Collisions with birds are a serious problem for commercial aircraft, costing the industry billions of dollars and killing thousands of animals every year. New research shows that a robotic imitation of a peregrine falcon could be an effective way to keep them out of flight paths.
Worldwide, so-called birdstrikes are estimated to cost the civil aviation industry almost US $1.4 billion annually. Nearby habitats are often deliberately made unattractive to birds, but airports also rely on a variety of deterrents designed to scare them away, such as loud pyrotechnics or speakers that play distress calls from common species.
However, the effectiveness of these approaches tends to decrease over time, as the birds get desensitized by repeated exposure, says Charlotte Hemelrijk, a professor on the faculty of science and engineering at the University of Groningen, in the Netherlands. Live hawks or blinding lasers are also sometimes used to disperse flocks, she says, but this is controversial as it can harm the animals, and keeping and training falcons is not cheap.
“The birds don’t distinguish [RobotFalcon] from a real falcon, it seems.” —Charlotte Hemelrijk, University of Groningen
In an effort to find a more practical and lasting solution, Hemelrijk and colleagues designed a robotic peregrine falcon that can be used to chase flocks away from airports. The device is the same size and shape as a real hawk, and its fiberglass and carbon-fiber body has been painted to mimic the markings of its real-life counterpart.
Rather than flapping like a bird, the RobotFalcon relies on two small battery-powered propellers on its wings, which allows it to travel at around 30 miles per hour for up to 15 minutes at a time. A human operator controls the machine remotely from a hawk’s-eye perspective via a camera perched above the robot’s head.
To see how effective the RobotFalcon was at scaring away birds, the researchers tested it against a conventional quadcopter drone over three months of field testing, near the Dutch city of Workum. They also compared their results to 15 years of data collected by the Royal Netherlands Air Force that assessed the effectiveness of conventional deterrence methods such as pyrotechnics and distress calls.
In a paper published in the Journal of the Royal Society Interface, the team showed that the RobotFalcon cleared fields of birds faster and more effectively than the drone. It also kept birds away from fields longer than distress calls, the most effective of the conventional approaches.
There was no evidence of birds getting habituated to the RobotFalcon over three months of testing, says Hemelrijk, and the researchers also found that the birds exhibited behavior patterns associated with escaping from predators much more frequently with the robot than with the drone. “The way of reacting to the RobotFalcon is very similar to the real falcon,” says Hemelrijk. “The birds don’t distinguish it from a real falcon, it seems.”
Other attempts to use hawk-imitating robots to disperse birds have had less promising results, though. Morgan Drabik-Hamshare, a research wildlife biologist at the DoA, and her colleagues published a paper in Scientific Reports last year that described how they pitted a robotic peregrine falcon with flapping wings against a quadcopter and a fixed-wing remote-controlled aircraft.
They found the robotic falcon was the least effective of the three at scaring away turkey vultures, with the quadcopter scaring the most birds off and the remote-controlled plane eliciting the quickest response. “Despite the predator silhouette, the vultures did not perceive the predator UAS [unmanned aircraft system] as a threat,” Drabik-Hamshare wrote in an email.
Zihao Wang, an associate lecturer at the University of Sydney, in Australia, who develops UAS for bird deterrence, says the RobotFalcon does seem to be effective at dispersing flocks. But he points out that its wingspan is nearly twice the diagonal length of the quadcopter it was compared with, which means it creates a much larger silhouette when viewed from the birds’ perspective. This means the birds could be reacting more to its size than its shape, and he would like to see the RobotFalcon compared with a similar size drone in the future.
The unique design also means the robot requires an experienced and specially trained operator, Wang adds, which could make it difficult to roll out widely. A potential solution could be to make the system autonomous, he says, but it’s unclear how easy this would be.
Hemelrijk says automating the RobotFalcon is probably not feasible, both due to strict regulations around the use of autonomous drones near airports as well as the sheer technical complexity. Their current operator is a falconer with significant experience in how hawks target their prey, she says, and creating an autonomous system that could recognize and target bird flocks in a similar way would be highly challenging.
But while the need for skilled operators is a limitation, Hemelrijk points out that most airports already have full-time staff dedicated to bird deterrence, who could be trained. And given the apparent lack of habituation and the ability to chase birds in a specific direction—so that they head away from runways—she thinks the robotic falcon could be a useful addition to their arsenal.

IEEE Life Fellow Vinton “Vint” Cerf, widely known as the “Father of the Internet,” is the recipient of the 2023 IEEE Medal of Honor. He is being recognized “for co-creating the Internet architecture and providing sustained leadership in its phenomenal growth in becoming society’s critical infrastructure.”
While working as a program manager at the U.S. Defense Advanced Research Projects Agency (DARPA) Information Processing Techniques Office in 1974, Cerf and IEEE Life Fellow Robert Kahn designed the Transmission Control Protocol and the Internet Protocol. TCP manages data packets sent over the Internet, making sure they don’t get lost, are received in the proper order, and are reassembled at their destination correctly. IP manages the addressing and forwarding of data to and from its proper destinations. Together they make up the Internet’s core architecture and enable computers to connect and exchange traffic.
“Cerf’s tireless commitment to the Internet’s evolution, improvement, oversight, and evangelism throughout its history has made an indelible impact on the world,” said one of the endorsers of the award. “It is largely due to his efforts that we even have the Internet, which has changed the way society lives.
“The Internet has enabled a large part of the world to receive instant access to news, brought us closer to friends and loved ones, and made it easier to purchase products online,” the endorser said. “It’s improved access to education and scientific discourse, made smartphones useful, and opened the door for social media, cloud computing, video conferencing, and streaming. Cerf also saw early on the importance of decentralized control, with no one company or government completely in charge.”
Since 2005, Cerf has been vice president and chief Internet evangelist at Google in Reston, Va., spreading the word about adopting the Internet in service to public good. He is responsible for identifying new technologies and enabling policies that support the development of advanced, Internet-based products and services.
Enhancing the World Wide Web
Cerf left DARPA in 1982 to join Microwave Communications Inc. (now part of WorldCom), headquartered in Washington, D.C., as vice president of its digital information services division. A year later, he led the development of MCI Mail, the first commercial email service on the Internet.
In 1986 he left the company to become vice president of the newly formed Corporation for National Research Initiatives, also in Reston. He worked alongside Kahn at the not-for-profit organization, developing digital libraries, gigabit speed networks, and knowledge robots (mobile software agents used in computer networks).
He returned to MCI in 1994 and served as a senior vice president for 11 years before joining Google.
“It is largely due to Cerf’s efforts that we even have the Internet.”
Together with Kahn, Cerf founded the nonprofit Internet Society in 1992. The organization helps set technical standards, develops Internet infrastructure, and helps lawmakers set policy.
Cerf served as its president from 1992 to 1995 and was chairman of the board of the Internet Corp. for Assigned Names and Numbers from 2000 to 2007. ICANN works to ensure a stable, secure, and interoperable Internet by managing the assignment of unique IP addresses and domain names. It also maintains tables of registered parameters needed for the protocol standards developed by the Internet Engineering Task Force.

An astonishing amount of that data is recorded, stored, analyzed, and shared by media companies looking to pitch you content and ads, retailers aiming to sell you more of what you’ve already bought, and potential distant relatives hitting you up on genealogy sites. And sometimes, if you’re suspected of participating in illegal activities, that data can bring you under the scrutiny of law enforcement officials.
Contributing Editor Mark Harris spent months poring over court documents and other records to understand how the U.S. Federal Bureau of Investigation and other agencies exploited vast troves of data to conduct the largest criminal investigation in U.S. history: into the violent overtaking of the Capitol building on 6 January 2021.
The events of that day unfolded on live television watched by millions. But in order for investigators to identify suspects amidst a mob of thousands, it had to cast a very wide net and sought the cooperation of tech giants like Google, Facebook, and Snap and carriers like Verizon and T-Mobile. As Harris painstakingly documents in “How the Police Exploited the Capitol Rioters’ Digital Records,” some of the information the FBI used was intentionally shared by rioters on social media, while other information was gleaned from the kind of data we all heedlessly cast off during the course of the day, like the order for pizza that landed one group of rioters in hot water or the automated license-plate readings that were cited in 20 cases.
“In the eternal struggle between security and privacy, the best that digital-rights activists can hope for is to watch the investigators as closely as they are watching us.” —Mark Harris
The ability to ingest multiple data streams and analyze them to trace rioters’ journeys to, through, and back from the Capitol has led to 950 arrests, with more than half leading to guilty pleas and 40 to guilty verdicts as of this writing. But as the privacy advocates Harris interviewed point out, while these tools helped law enforcement hold some people accountable for their actions that day, those same tools can be used by the state against law-abiding citizens, not just in the United States, but anywhere. And the data we make available (knowingly or not), often for the sake of convenience or as the price of admission, leaves us vulnerable to bad actors, be they governments, corporations, or individuals.
The writer David Brin foretold a version of our current panopticon in his 1998 book The Transparent Society. In it, he acknowledges the risks of surveillance technology but contends that the very ubiquity of that technology is in itself a safeguard against abuse by giving everyone the ability to shine a light on the dark corners of individual and institutional behavior: His stance jibes with Harris’s final observation: “In the eternal struggle between security and privacy, the best that digital-rights activists can hope for is to watch the investigators as closely as they are watching us.”
But as Brin points out, watching the watchers isn’t enough to guarantee a free and open society. As data-driven prosecutions for the 6 January insurrection continue, it’s worth considering the linkage Brin makes between liberty and accountability, which he says, “is the one fundamental ingredient on which liberty thrives. Without the accountability that derives from openness—enforceable upon even the mightiest individuals and institutions—how can freedom survive?”

There are two major reasons for this: first, EVs are not going to reach the numbers required by 2050 to hit their needed contribution to net zero goals, and even if they did, a host of other personal, social and economic activities must be modified to reach the total net zero mark.
For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article) demonstrates the U.S. must have 90 percent of its vehicles, or some 350 million EVs, on the road by 2050 in order to hit its emission targets. The likelihood of this occurring is infinitesimal. Some estimates indicate that about 40 percent of vehicles on US roads will be ICE vehicles in 2050, while others are less than half that figure.
For the U.S. to hit the 90 percent EV target, sales of all new ICE vehicles across the U.S. must cease by 2038 at the latest, according to research company BloombergNEF (BNEF). Greenpeace, on the other hand, argues that sales of all diesel and petrol vehicles, including hybrids, must end by 2030 to meet such a target. However, achieving either goal would likely require governments offering hundreds of billions of dollars, if not trillions, in EV subsidies to ICE owners over the next decade, not to mention significant investments in EV charging infrastructure and the electrical grid. ICE vehicle households would also have to be convinced that they would not be giving activities up by becoming EV-only households.
As a reality check, current estimates for the number of ICE vehicles still on the road worldwide in 2050 range from a low of 1.25 billion to more than 2 billion.
Even assuming that the required EV targets were met in the U.S. and elsewhere, it still will not be sufficient to meet net zero 2050 emission targets. Transportation accounts for only 27 percent of greenhouse gas emissions (GHG) in the U.S.; the sources of the other 73 percent of GHG emissions must be reduced as well. Even in the transportation sector, more than 15 percent of the GHG emissions are created by air and rail travel and shipping. These will also have to be decarbonized.
Nevertheless, for EVs themselves to become true zero emission vehicles, everything in their supply chain from mining to electricity production must be nearly net-zero emission as well. Today, depending on the EV model, where it charges, and assuming it is a battery electric and not a hybrid vehicle, it may need to be driven anywhere from 8,400 to 13,500 miles, or controversially, significantly more to generate less GHG emissions than an ICE vehicle. This is due to the 30 to 40 percent increase in emissions EVs create in comparison to manufacturing an ICE vehicle, mainly from its battery production.
In states (or countries) with a high proportion of coal-generated electricity, the miles needed to break-even climb more. In Poland and China, for example, an EV would need to be driven 78,700 miles to break-even. Just accounting for miles driven, however, BEVs cars and trucks appear cleaner than ICE equivalents nearly everywhere in the U.S. today. As electricity increasingly comes from renewables, total electric vehicle GHG emissions will continue downward, but that will take at least a decade or more to happen everywhere across the U.S. (assuming policy roadblocks disappear), and even longer elsewhere.
If EVs aren’t enough, what else is needed?
Given that EVs, let alone the rest of the transportation sector, likely won’t hit net zero 2050 targets, what additional actions are being advanced to reduce GHG emissions?
A high priority, says IEA’s Birol, is investment in across-the-board energy-related technology research and development and their placement into practice. According to Birol, “IEA analysis shows that about half the reductions to get to net zero emissions in 2050 will need to come from technologies that are not yet ready for market.”
Many of these new technologies will be aimed at improving the efficient use of fossil fuels, which will not be disappearing anytime soon. The IEA expects that energy efficiency improvement, such as the increased use of variable speed electric motors, will lead to a 40 percent reduction in energy-related GHG emissions over the next twenty years.
But even if these hoped for technological improvements arrive, and most certainly if they do not, the public and businesses are expected to take more energy conscious decisions to close what the United Nations says is the expected 2050 “emissions gap.” Environmental groups foresee the public needing to use electrified mass transit, reduce long-haul flights for business as well as pleasure), increase telework, walk and cycle to work or stores, change their diet to eat more vegetables, or if absolutely needed, drive only small EVs. Another expectation is that homeowners and businesses will become “fully electrified” by replacing oil, propane and gas furnaces with heat pumps along with gas fired stoves as well as installing solar power and battery systems.

Underpinning the behavioral changes being urged (or encouraged by legislation) is the notion of rejecting the current car-centric culture and completely rethinking what personal mobility means. For example, researchers at University of Oxford in the U.K. argue that, “Focusing solely on electric vehicles is slowing down the race to zero emissions.” Their studyfound “emissions from cycling can be more than 30 times lower for each trip than driving a fossil fuel car, and about ten times lower than driving an electric one.” If just one out of five urban residents in Europe permanently changed from driving to cycling, emissions from automobiles would be cut by 8 percent, the study reports.
Even then, Oxford researchers concede, breaking the car’s mental grip on people is not going to be easy, given the generally poor state of public transportation across much of the globe.
Behavioral change is hard
How willing are people to break their car dependency and other energy-related behaviors to address climate change? The answer is perhaps some, but maybe not too much. A Pew Research Centersurvey taken in late 2021 of seventeen countries with advanced economies indicated that 80 percent of those surveyed were willing to alter how then live and work to combat climate change.
However, a Kanter Publicsurvey of ten of the same countries taken at about the same time gives a less positive view, with only 51 percent of those polled stating they would alter their lifestyles. In fact, some 74 percent of those polled indicated they were already “proud of what [they are] currently doing” to combat climate change.
What both polls failed to explore are what behaviors specifically would respondents being willing to permanently change or give up in their lives to combat climate change?
For instance, how many urban dwellers, if told that they must forever give up their cars and instead walk, cycle or take public transportation, would willingly agree to doing so? And how many of those who agreed, would also consent to go vegetarian, telework, and forsake trips abroad for vacation?
It is one thing to answer a poll indicating a willingness to change, and quite another to “walk the talk” especially if there are personal, social or economic inconveniences or costs involved. For instance, recent U.S. survey information shows that while 22 percent of new car buyers expressed interest in a battery electric vehicle (BEV), only 5 percent actually bought one.

However, in countless other urban areas, especially across most of the U.S., even those wishing to forsake owning a car would find it very difficult to do so without a massive influx of investment into all forms of public transport and personal mobility to eliminate the scores of US transit deserts.
As Tony Dutzik of the environmental advocacy group Frontier Group has written that in the U.S. “the price of admission to jobs, education and recreation is owning a car.” That’s especially true if you are a poor urbanite. Owning a reliable automobile has long been one of the only successful means of getting out of poverty.
Massive investment in new public transportation in the U.S. in unlikely, given its unpopularity with politicians and the public alike. This unpopularity has translated into aging and poorly-maintained bus, train and transit systems that few look forward to using. The American Society of Civil Engineers gives the current state of American public transportation a grade of D- and says today’s $176 billion investment backlog is expected to grow to $250 billion through 2029.
While the $89 billion targeted to public transportation in the recently passed Infrastructure Investment and Jobs Act will help, it also contains more than $351 billion for highways over the next five years. Hundreds of billions in annual investment are needed not only to fix the current public transport system but to build new ones to significantly reduce car dependency in America. Doing so would still take decades to complete.
Yet, even if such an investment were made in public transportation, unless its service is competitive with an EV or ICE vehicle in terms of cost, reliability and convenience, it will not be used. With EVs costing less to operate than ICE vehicles, the competitive hurdle will increase, despite the moves to offer free transit rides. Then there is the social stigma attached riding public transportation that needs to be overcome as well.
A few experts proclaim that ride-sharing using autonomous vehicles will separate people from their cars. Some even claim such AV sharing signals the both the end of individual car ownership as well as the need to invest in public transportation. Both outcomes are far from likely.
Other suggestions include redesigning cities to be more compact and more electrified, which would eliminate most of the need for personal vehicles to meet basic transportation needs. Again, this would take decades and untold billions of dollars to do so at the scale needed. The San Diego, California region has decided to spend $160 billion as a way to meet California’s net zero objectives to create “a collection of walkable villages serviced by bustling (fee-free) train stations and on-demand shuttles” by 2050. However, there has been public pushback over how to pay for the plan and its push to decrease personal driving by imposing a mileage tax.
According to University of Michigan public policy expert John Leslie King, the challenge of getting to net zero by 2050 is that each decarbonization proposal being made is only part of the overall solution. He notes, “You must achieve all the goals, or you don’t win. The cost of doing each is daunting, and the total cost goes up as you concatenate them.”
Concatenated costs also include changing multiple personal behaviors. It is unlikely that automakers, having committed more than a trillion dollars so far to EVs and charging infrastructure, are going to support depriving the public of the activities they enjoy today as a price they pay to shift to EVs. A war on EVs will be hard fought.
The number of Massachusetts households that can afford or are willing to buy an EV and or convert their homes to a heat pump system in the next eight years, even with a current state median household income of $89,000 and subsidies, is likely significantly smaller than the targets set. So, what happens if by 2030, the numbers are well below target, not only in Massachusetts, but other states like California, New York, or Illinois that also have aggressive GHG emission reduction targets?
Will governments move from encouraging behavioral changes to combat climate change or, in frustration or desperation, begin mandating them? And if they do, will there be a tipping point that spurs massive social resistance?
For example, dairy farmers in the Netherlands have been protesting plans by the government to force them to cut their nitrogen emissions. This will require dairy farms to reduce their livestock, which will make it difficult or impossible to stay in business. The Dutch government estimates 11,200 farms must close, and another 17,600 to reduce their livestock numbers. The government says farmers who do not comply will have their farms taken away by forced buyouts starting in 2023.
California admits getting to a zero-carbon transportation system by 2045 means car owners must travel 25 percent below 1990 levels by 2030 and even more by 2045. If drivers fail to do so, will California impose weekly or monthly driving quotas, or punitive per mile driving taxes, along with mandating mileage data from vehicles ever-more connected to the Internet? The San Diego backlash over a mileage tax may be just the beginning.
“EVs,” notes King, “pull an invisible trailer filled with required major lifestyle changes that the public is not yet aware of.”
When it does, do not expect the public to acquiesce quietly.
In the final article of the series, we explore potential unanticipated consequences of transitioning to EVs at scale.

If electric vertical takeoff and landing aircraft do manage to revolutionize transportation, the date of 5 October 2011, may live on in aviation lore. That was the day when a retired mechanical engineer named Marcus Leng flew a home-built eVTOL across his front yard in Warkworth, Ont., Canada, startling his wife and several of his friends.
“So, take off, flew about 6 feet above the ground, pitched the aircraft towards my wife and the two couples that were there, who were behind automobiles for protection, and decided to do a skidding stop in front of them. Nobody had an idea that this was going to be happening,” recalls Leng.
But as he looked to set his craft down, he saw a wing starting to dig into his lawn. “Uh-oh, this is not good,” he thought. “The aircraft is going to spin out of control. But what instead happened was the propulsion systems revved up and down so rapidly that as the aircraft did that skidding turn, that wing corner just dragged along my lawn exactly in the direction I was holding the aircraft, and then came to a stable landing,” says Leng. At that point, he knew that such an aircraft was viable “because to have that sort of an interference in the aircraft and for the control systems to be able to control it was truly remarkable.”
It was the
second time anyone, anywhere had ever flown an eVTOL aircraft.
350 organizations in 48 countries are designing, building, or flying eVTOLs, according to the Vertical Flight Society. These companies are fueled by more than US $7 billion and perhaps as much as $10 billion in startup funding. And yet, 11 years after Leng’s flight, no eVTOLs have been delivered to customers or are being produced at commercial scale. None have even been certified by a civil aviation authority in the West, such as the U.S. Federal Aviation Administration or the European Union Aviation Safety Agency.
But 2023 looks to be a pivotal year for eVTOLs. Several well-funded startups are expected to reach important early milestones in the certification process. And the company Leng founded, Opener, could beat all of them by making its first deliveries—which would also be the first for any maker of an eVTOL.
Today, some 350 organizations in 48 countries are designing, building, or flying eVTOLs, according to the Vertical Flight Society.
As of late October, the company had built at its facility in Palo Alto, Calif., roughly 70 aircraft—considerably more than are needed for simple testing and evaluation. It had flown more than 30 of them. And late in 2022, the company had begun training a group of operators on a state-of-the-art virtual-reality simulator system.
Opener’s highly unusual, single-seat flier is intended for personal use rather than transporting passengers, which makes it almost unique. Opener intends to have its aircraft classified as an “ultralight,” enabling it to bypass the rigorous certification required for commercial-transport and other aircraft types. The certification issue looms as a major unknown over the entire eVTOL enterprise, at least in the United States, because, as the blog Jetlaw.com
noted last August, “the FAA has no clear timeline or direction on when it will finalize a permanent certification process for eVTOL.”
Opener’s strategy is not without risks, either. For one, there’s no guarantee that the FAA will ultimately agree that Opener’s aircraft, called BlackFly, qualifies as an ultralight. And not everyone is happy with this approach. “My concern is, these companies that are saying they can be ultralights and start flying around in public are putting at risk a $10 billion [eVTOL] industry,” says Mark Moore, founder and chief executive of
Whisper Aero in Crossville, Tenn. “Because if they crash, people won’t know the difference” between the ultralights and the passenger eVTOLs, he adds. “To me, that’s unacceptable.” Previously, Moore led a team at NASA that designed a personal-use eVTOL and then served as engineering director at Uber’s Elevate initiative.

Making eVTOLs personal
Opener’s aircraft is as singular as its business model. It’s a radically different kind of aircraft, and it sprang almost entirely from Leng’s fertile mind.
“As a kid,” he says, “I already envisioned what it would be like to have an aircraft that could seamlessly do a vertical takeoff, fly, and land again without any encumbrances whatsoever.” It was a vision that never left him, from a mechanical-engineering degree at the University of Toronto, management jobs in the aerospace industry, starting a company and making a pile of money by
inventing a new kind of memory foam, and then retiring in 1996 at the age of 36.
The fundamental challenge to designing a vertical-takeoff aircraft is endowing it with both vertical lift and efficient forward cruising. Most eVTOL makers achieve this by physically tilting multiple large rotors from a vertical rotation axis, for takeoff, to a horizontal one, for cruising. But the mechanism for tilting the rotors must be extremely robust, and therefore it inevitably adds substantial complexity and weight. Such tilt-rotors also entail significant compromises and trade-offs in the size of the rotors and their placement relative to the wings.
Opener’s BlackFly ingeniously avoids having to make those trade-offs and compromises. It has two wings, one in front and one behind the pilot. Affixed to each wing are four motors and rotors—and these never change their orientation relative to the wings. Nor do the wings move relative to the fuselage. Instead, the entire aircraft rotates in the air to transition between vertical and horizontal flight.
To control the aircraft,
the pilot moves a joystick, and those motions are instantly translated by redundant flight-control systems into commands that alter the relative thrust among the eight motor-propellers.
Visually, it’s an astounding aircraft, like something from a 1930s pulp sci-fi magazine. It’s also a triumph of engineering.
Leng says the journey started for him in 2008, when “I just serendipitously stumbled upon the fact that all the key technologies for making electric VTOL human flight practical were coming to a nexus.”
The journey that made Leng’s dream a reality kicked into high gear in 2014 when a chance meeting with investor Sebastian Thrun at an aviation conference led to Google cofounder
Larry Page investing in Leng’s project.
Designing an eVTOL from first principles
Leng started in his basement in 2010, spending his own money on a mélange of home-built and commercially available components. The motors were commercial units that Leng modified himself, the motor controllers were German and off the shelf, the inertial-measurement unit was open source and based on an Arduino microcontroller. The batteries were modified model-aircraft lithium-polymer types.
“The main objective behind this was proof of concept,” he says.“I had to prove it to myself, because up until that point, they were just equations on a piece of paper. I had to get to the point where I knew that this could be practical.”
After his front-yard flight in 2011, there followed several years of refining and rebuilding all of the major components until they achieved the specifications Leng wanted. “Everything on BlackFly is from first principles,” he declares.
The motors started out generating 160 newtons (36 pounds) of static thrust. It was way too low. “I actually tried to purchase motors and motor controllers from companies that manufactured those, and I specifically asked them to customize those motors for me, by suggesting a number of changes,” he says. “I was told that, no, those changes won’t work.”
So he started designing his own brushless AC motors. “I did not want to design motors,” says Leng. “In the end, I was stunned at how much improvement we could make by just applying first principles to this motor design.”
Eleven years after Leng’s flight, no eVTOLs have been delivered to customers or are being produced at commercial scale.
To increase the power density, he had to address the tendency of a motor in an eVTOL to overheat at high thrust, especially during hover, when cooling airflow over the motor is minimal. He began by designing a system to force air through the motor. Then he began working on the rotor of the motor (not to be confused with the rotor wings that lift and propel the aircraft). This is the spinning part of a motor, which is typically a single piece of electrical steel. It’s an iron alloy with very high magnetic permeability.
By layering the steel of the rotor, Leng was able to greatly reduce its heat generation, because the thinner layers of steel limited the eddy currents in the steel that create heat. Less heat meant he could use higher-strength neodymium magnets, which would otherwise become demagnetized. Finally, he rearranged those magnets into a configuration called a Halbach array. In the end Leng’s motors were able to produce 609 newtons (137 lbs.) of thrust.
Overall, the 2-kilogram motors are capable of sustaining 20 kilowatts, for a power density of 10 kilowatts per kilogram, Leng says. It’s an extraordinary figure. One of the few motor manufacturers claiming a density in that range is
H3X Technologies, which says its HPDM-250 clocks in at 12 kw/kg.
Software engineer Bodhi Connolly took a BlackFly eVTOL aircraft for a twilight spin on 29 July 2022, at the EAA AirVenture show in Oshkosh, Wis.
Advanced air mobility for everybody
The brain of the BlackFly consists of three independent flight controllers, which calculate the aircraft’s orientation and position, based on readings from the inertial-measurement units, GPS receivers, and magnetometers. They also use pitot tubes to measure airspeed. The flight controllers continually cross-check their outputs to make sure they agree. They also feed instructions, based on the operator’s movement of the joystick, to the eight motor controllers (one for each motor).
Equipped with these sophisticated flight controllers, the fly-by-wire BlackFly is similar in that regard to the hobbyist drones that rely on processors and clever algorithms to avoid the tricky manipulations of sticks, levers, and pedals required to fly a traditional fixed- or rotary-wing aircraft.
That sophisticated, real-time control will allow a far larger number of people to consider purchasing a BlackFly when it becomes available. In late November, Opener had not disclosed a likely purchase price, but in the past the company had suggested that BlackFly would cost as much as a luxury SUV. So who might buy it? CEO Ken Karklin points to several distinct groups of potential buyers who have little in common other than wealth.
There are early tech adopters and also people who are already aviators and are “passionate about the future of electric flight, who love the idea of being able to have their own personal vertical-takeoff-and-landing, low-maintenance, clean aircraft that they can fly in rural and uncongested areas,” Karklin says. “One of them is a business owner. He has a plant that’s a 22-mile drive but would only be a 14-mile flight, and he wants to install charging infrastructure on either end and wants to use it to commute every day. We love that.”
Others are less certain about how, or even whether, this market segment will establish itself. “When it comes to personal-use eVTOLs, we are really struggling to see the business case,” says Sergio Cecutta, founder and partner at SMG Consulting, where he studies eVTOLs among other high-tech transportation topics. “I’m not saying they won’t sell. It’s how many will they sell?” He notes that Opener is not the only eVTOL maker pursuing a path to success through the ultralight or some other specialized FAA category. As of early November, the list included
Alauda Aeronautics,Air,Alef, Bellwether Industries, Icon Aircraft, Jetson, Lift Aircraft, andRyse Aero Technologies.
What makes Opener special? Both Karklin and Leng emphasize the value of all that surrounds the BlackFly aircraft. For example, there are virtual-reality-based simulators that they say enable them to fully train an operator in 10 to 15 hours. The aircraft themselves are heavily instrumented: “Every flight, literally, there’s over 1,000 parameters that are recorded, some of them at 1,000 hertz, some 100 Hz, 10 Hz, and 1 Hz,” says Leng. “All that information is stored on the aircraft and downloaded to our database at the end of the flight. When we go and make a software change, we can do what’s called regression testing by running that software using all the data from our previous flights. And we can compare the outputs against what the outputs were during any specific flight and can automatically confirm that the changes that we’ve made are without any issues. And we can also compare, to see if they make an improvement.”
Ed Lu, a former NASA astronaut and executive at Google, sits on Opener’s safety-review board. He says what impressed him most when he first met the BlackFly team was “the fact that they had based their entire development around testing. They had a wealth of flight data from flying this vehicle in a drone mode, an unmanned mode.” Having all that data was key. “They could make their decisions based not on analysis, but after real-world operations,” Lu says, adding that he is particularly impressed by Opener’s ability to manage all the flight data. “It allows them to keep track of every aircraft, what sensors are in which aircraft, which versions of code, all the way down to the flights, to what happened in each flight, to videos of what’s happening.” Lu thinks this will be a huge advantage once the aircraft is released into the “real” world.
Karklin declines to comment on whether an ultralight approval, which is governed by what the FAA designates “
Part 103,” might be an opening move toward an FAA type certification in the future. “This is step one for us, and we are going to be very, very focused on personal air vehicles for recreational and fun purposes for the foreseeable future,” he says. “But we’ve also got a working technology stack here and an aircraft architecture that has considerable utility beyond the realm of Part-103 [ultralight] aircraft, both for crewed and uncrewed applications.” Asked what his immediate goals are, Karklin responds without hesitating. “We will be the first eVTOL company, we believe, in serial production, with a small but steadily growing revenue and order book, and with a growing installed base of cloud-connected aircraft that with every flight push all the telemetry, all the flight behavior, all the component behavior, all the operator-behavior data representing all of this up to the cloud, to be ingested by our back office, and processed. And that provides us a lot of opportunity.”

Some observers say the metaverse is an expanded set of digital worlds that will grow out of the online environments that people are already familiar with, such as enhancing the extended-reality (XR) experience used in online gaming. The world they imagine is expected to offer new features and capabilities that accelerate society’s digital transformation and enhance sustainability by reducing the need for people to travel to meetings and perform resource-intensive activities.
Others say the metaverse will usher in a decentralized ecosystem that empowers users to create digital assets of their own choosing and engage in digital commerce. Because the architecture would be open, decentralized, and without gatekeepers, this version is expected to democratize the Internet by making it transparent, accessible, and interoperable to everyone.
However the metaverse evolves, one thing is certain: It has tremendous potential to fundamentally transform the ways we work, learn, play, and live. But there will be issues to deal with along the way.
That is why the IEEE Standards Association (IEEE SA) is working to help define, develop, and deploy the technologies, applications, and governance practices needed to help turn metaverse concepts into practical realities, and to drive new markets.
Technical and societal challenges
The technical and societal challenges that come with designing and building metaverse environments include:
Better user interfaces.
Lower system latency.
More tightly integrated, interoperable XR technologies.
Better 3D modeling and volumetric video rendering.
Improved ways to acquire, render, store, and protect geospatial data.
Lower power consumption.
Interacting with the Internet.
Consensus is needed to address the wide variety of views held on technosocial issues such as user identity, credentialing, privacy, openness, ethics, accessibility, and user safety.
New technical standards
IEEE SA recently formed its metaverse standards committee, the first committee of a major worldwide standards development organization designed to advance metaverse-related technologies and applications. It will do so by developing and maintaining technical standards, creating recommended practices, and writing guides.
In addition, technical standards and activities are incubating new ideas on topics that are expected to be of great interest to industry.
The IEEE P7016 Standard for Ethically Aligned Design and Operation of Metaverse Systems will provide a high-level overview of the technosocial aspects of metaverse systems and specify an ethical assessment methodology for use in their design and operation. The standard will include guidance to developers on how to adapt their processes to prioritize ethically aligned design. In addition, IEEE P7016 will help define ethical system content on accessibility and functional safety. Also included will be guidance on how to promote ethically aligned values and robust public engagement in the research, implementation, and proliferation of metaverse systems to increase human well-being and environmental sustainability.
Two industry-focused initiatives
IEEE SA also recently launched two Industry Connections activities specifically for the metaverse. The IC program facilitates collaboration and consensus-building among participants. It also provides IEEE resources to help produce standards proposals; white papers and other reports; events; software tools; and Web services.
The Decentralized Metaverse Initiative has identified a goal of developing and providing guidelines for implementing decentralized metaverses, which not only could capitalize on intellectual property and virtual assets in decentralized ways but also could benefit from other potential features of decentralized architectures.
The Persistent Computing for Metaverse Initiative will focus on the technologies needed to build, operate, and upgrade metaverse experiences. It includes computation, storage, communications, data structures, and artificial intelligence. This group will facilitate discussions and collaborations on persistent computing, steer and give advice on research and development, and provide technical guidelines and references.
Webinars with experts
The IEEE Metaverse Congress offers a series of webinars that provide a comprehensive, global view from experts who are involved with the technology’s development, design, and governance.

This is the tenth in a
series of articles exploring the major technological and social challenges that must be addressed as we move from vehicles with internal-combustion engines to electric vehicles at scale. In reviewing each article, readers should bear in mind Nobel Prize–winning physicist Richard Feynman’s admonition: “For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.”
Perhaps, but getting the vast majority of 111 million
US households who own one or more light duty internal combustion vehicles to switch to EVs is going to take time. Even if interest in purchasing an EV is increasing, close to 70 percent of Americans are still leaning towards buying an ICE vehicles as their next purchase. In the UK, only 14 percent of drivers plan to purchase an EV as their next car.
Even when there is an expressed interest in purchasing a battery electric or hybrid vehicle, it often did not turn into an actual purchase. A
2022 CarGurus survey found that 35 percent of new car buyers expressed an interest in purchasing a hybrid, but only 13 percent eventually did. Similarly, 22 percent expressed interest in a battery electric vehicle (BEV), but only 5 percent bought one.
Each potential EV buyer assesses their individual needs against the benefits and risks an EV offers. However, until mainstream public confidence reaches the point where the perceived combination of risks of a battery electric vehicle purchase (range, affordability, reliability and behavioral changes) match that of an ICE vehicle, then EV purchases are going to be the exception rather than the norm.
Arguments over how much range is needed are contentious. There are some who argue that because
95 percent of American car trips are 30 miles or less, a battery range of 250 miles or less is all that is needed. They also point out that this would reduce the price of the EV, since batteries account for about 30 percent of an EVs total cost. In addition, using smaller batteries would allow more EVs to be built, and potentially relieve pressure on the battery supply chain. If longer trips are needed, well, “bring some patience and enjoy the charging experience” seems to be the general advice.
While perhaps logical, these arguments are not going to influence typical buying decisions much. The first question potential EV buyers are going to ask themselves is, “Am I going to be paying more for a compromised version of mobility?” says Alexander Edwards, President of
Strategic Vision, a research-based consultancy that aims to understand human behavior and decision-making.
Driver’s side view of 2024 Chevrolet Equinox EV 3LT.Chevrolet
Edwards explains potential customers do not have
range anxietyper se: If they believe they require a vehicle that must go 400 miles before stopping, “even if once a month, once a quarter, or once a year,” all vehicles that cannot meet that criteria will be excluded from their buying decision. Range anxiety, therefore, is more a concern for EV owners. Edwards points out that regarding range, most BEV owners own at least one ICE vehicle to meet their long-distance driving needs.
What exactly is the “range” of a BEV is itself becoming a heated point of contention. While ICE vehicles driving ranges are affected by weather and driving conditions, the effects are well-understood after decades of experience. This experience is lacking with non-EV owners. Extreme heat and cold negatively
affect EV battery ranges and charging time, as do driving speeds and terrain.
Peter Rawlinson serves as the CEO and CTO of Lucid.Lucid
Some automakers are reticent to say how much range is affected under differing conditions. Others, like Ford’s CEO Jim Farley, freely admits, “If you’re pulling 10,000 pounds, an electric truck is not the right solution. And 95 percent of our customers tow more than 10,000 pounds.” GM, though, is promising it will meet heavier towing requirements with its 2024 Chevrolet Silverado EV. However, Lucid Group CEO Peter Rawlinson in a non-too subtle dig at both Ford and GM said, “The correct solution for an affordable pickup truck today is the internal combustion engine.”
Ford’s Farley foresees that the heavy-duty truck segment will be sticking with ICE trucks for a while, as “it will probably go hydrogen fuel cell before it goes pure electric.” Many in the auto industry are warning that realistic BEV range numbers under varying conditions
need to be widely published, else risk creating a backlash against EVs in general.
Price is another EV purchase risk that is comparable to EV range. Buying a new car is the second most expensive purchase a consumer makes behind buying a house. Spending nearly
100 percent of an annual US median household income on an unfamiliar technology is not a minor financial ask.
That is one reason why legacy automakers and EV start-ups are attempting to follow
Tesla’s success in the luxury vehicle segment, spending much of their effort producing vehicles that are “above the median average annual US household income, let alone buyer in new car market,” Strategic Vision’s Edwards says. On top of the twenty or so luxury EVs already or soon to be on the market, Sony and Honda recently announced that they would be introducing yet another luxury EV in 2026.
It is true that there are some EVs that will soon appear in the competitive price range of ICE vehicles like the low-end
GM EV Equinox SUV presently priced around $30,000 with a 280-mile range. How long GM will be able to keep that price in the face of battery cost increases and inflationary pressure, is anyone’s guess. It has already started to increase the cost of its Chevrolet Bolt EVs, which it had slashed last year, “due to ongoing industry-related pricing pressures.”
The Lucid Air’s price ranges from $90,000 to $200,000 depending on options.Lucid.
Analysts believe Tesla intends to
spark an EV price war before its competitors are ready for one. This could benefit consumers in the short-term, but could also have long-term downside consequences for the EV industry as a whole. Tesla fired its first shot over its competitors’ bows with a recently announced price cut from $65,990 to $52,990 for its basic Model Y, with a range of 330 miles. That makes the Model Y cost-competitive with Hyundai’s $45,500 IONIQ 5 e-SUV with 304 miles of range.
Tesla’s pricing power could be hard to counter, at least in the short term. Ford’s cheapest F-150 Lightning Pro is now $57,869 compared to $41,769 a year ago due to what Ford
says are “ongoing supply chain constraints, rising material costs and other market factors.” The entry level F-150 XL with an internal combustion engine has risen in the past year from about $29,990 to $33,695 currently.
Carlos Tavares, CEO of Stellantis.Stellantis
Automakers like Stellantis, freely acknowledge that EVs are too expensive for most buyers, with
Stellantis CEO Carlos Tavares even warning that if average consumers can’t afford EVs as ICE vehicle sales are banned, “There is potential for social unrest.” However, other automakers like BMW are quite unabashed about going after the luxury market which it terms “white hot.” BMW’s CEO Oliver Zipse does say the company will not leave the “lower market segment,” which includes the battery electric iX1 xDrive30 that retails for A$82,900 in Australia and slightly lower elsewhere. It is not available in the United States.
The fact that luxury EVs are
more profitable no doubt helps keep automakers focused on that market. Ford’s very popular Mustang Mach-E is having trouble maintaining profitability, for instance, which has forced Ford to raise its base price from $43,895 to $46,895. Even in the Chinese market where smaller EV sales are booming, profits are not. Strains on profitability for automakers and their suppliers may increase further as battery metals prices increase, warns data analysis company S&P Global Mobility.
Jim Rowan, Volvo Cars’ CEO and President.Volvo Cars
Interestingly, a 2019
Massachusetts Institute of Technology (MIT) study predicted that as EVs became more widespread, battery prices would climb because the demand for lithium and other battery metals would rise sharply. As a result, the study indicated EV/ICE price parity was likely closer to 2030 with the expectation that new battery chemistries would be introduced by then.
Many argue, however, that
total cost of ownership (TCO) should be used as the EV purchase decision criterion rather than sticker price. Total cost of ownership of EVs is generally less than an ICE vehicle over its expected life since they have lower maintenance costs and electricity is less expensive per mile than gasoline, and tax incentives and rebates help a lot as well.
However, how long it takes to hit the break-even point
depends on many factors, like the cost differential of a comparable ICE vehicle, depreciation, taxes, insurance costs, the cost of electricity/petrol in a region, whether charging takes place at home, etc. And TCO rapidly loses it selling point appeal if electricity prices go up, however, as is happening in the UK and in Germany.
Even if the total cost of ownership is lower for an EV, a potential EV customer may not be interested if meeting today’s monthly auto payments is difficult. Extra costs like needing to install a fast charger at home, which can add
several thousand dollars more, or higher insurance costs, which could add an extra $500-$600 a year, may also be seen as buying impediment and can change the TCO equation.
Reliability and other major tech risks
To perhaps distract wary EV buyers from range and affordability issues, the automakers have focused their efforts on highlighting EV performance.
Raymond Roth, a director at financial advisory firm Stout Risius Ross, observes among automakers, “There’s this arms race right now of best in class performance” being the dominant selling point.
This “wow” experience is being pursued by every EV automaker.
Mercedes CEO Kallenius, for example, says to convince its current luxury vehicle owners to an EV, “the experience for the customer in terms of the torque, the performance, everything [must be] fantastic.” Nissan, which seeks a more mass market buyer, runs commercials exclaiming, “Don’t get an EV for the ‘E’, but because it will pin you in your seat, sparks your imagination and takes your breath away.”
Ford believes it will earn $20 billion, Stellantis some $22.5 billion and GM $20 to $25 billion from paid software-enabled vehicle features by 2030.
EV reliability issues may also take one’s breath away. Reliability is “extremely important” to new-car buyers,
according to a 2022 report from Consumer Reports (CR). Currently, EV reliability is nothing to brag about. CR’s report says that “On average, EVs have significantly higher problem rates than internal combustion engine (ICE) vehicles across model years 2019 and 2020.” BEVs dwell at the bottom of the rankings.
Reliability may prove to be an Achilles heel to automakers like GM and Ford. GM CEO Mary Barra has very publicly promised that GM would no longer build “
crappy cars.” The ongoing problems with the Chevy Bolt undercuts that promise, and if its new Equinox EV has issues, it could hurt sales. Ford has reliability problems of its own, paying $4 billion in warranty costs last year alone. Its e-Mustang has been subject to several recalls over the past year. Even perceived quality-leader Toyota has been embarrassed by wheels falling off weeks after the introduction of its electric bZ4X SUV, the first in a new series “bZ”—beyond zero—electric vehicles.

Another reliability risk-related issue is getting an EV repaired when something goes awry, or there is an accident. Right now, there is a dearth of EV-certified mechanics and repair shops. The
UK Institute of the Motor Industry (IMI) needs 90,000 EV-trained technicians by 2030. The IMI estimates that less than 7 percent of the country’s automotive service workforce of 200,000 vehicle technicians is EV qualified. In the US, the situation is not better. The National Institute for Automotive Service Excellence (ASE), which certifies auto repair technicians, says the US has 229,000 ASE-certified technicians. However, there are only some 3,100 certified for electric vehicles. With many automakers moving to reduce their dealership networks, resolving problems that over-the-air (OTA) software updates cannot fix might be troublesome.
Furthermore, the costs and time needed to repair an EV are higher than for ICE vehicles,
according to the data analytics company CCC. Reasons include a greater need to use original equipment manufacturer (OEM) parts and the cost of scans/recalibration of the advanced driver assistance systems, which have been rising for ICE vehicles as well. Furthermore, technicians need to ensure battery integrity to prevent potential fires.
And some of batteries along with their battery management systems need work. Two examples: Recalls involving the GM Bolt and Hyundai Kona, with the former likely to cost GM $1.8 billion and Hyundai $800 million to fix, according to
Stout’s 2021 Automotive Defect and Recall Report. Furthermore, the battery defect data compiled by Stout indicates “incident rates are rising as production is increasing and incidents commonly occur across global platforms,” with both design and manufacturing defects starting to appear.
For a time in New York City, one had to be a licensed engineer to drive a steam-powered auto. In some aspects, EV drivers return to these roots. This might change over time, but for now it is a serious issue.” —John Leslie King
CCC data indicate that when damaged, battery packs do need replacement after a crash, and more than 50 percent of such vehicles were deemed a total loss by the insurance companies. EVs also need to revisit the repair center more times after they’ve been repaired than ICE vehicles, hinting at the increased difficulty in repairing them. Additionally, EV tire tread wear
needs closer inspection than on ICE vehicles. Lastly, as auto repair centers need to invest in new equipment to handle EVs, these costs will be passed along to customers for some time.
The risk has reached the attention of the
US Office of the National Cyber Director, which recently held a forum of government and automaker, suppliers and EV charging manufacturers focusing on “cybersecurity issues in the electric vehicle (EV) and electric vehicle supply equipment (EVSE) ecosystem.” The concern is that EV uptake could falter if EV charging networks are not perceived as being secure.
A sleeper risk that may explode into a massive problem is an EV owner’s right-to-repair their vehicle. In 2020, Massachusetts passed a law that allows a vehicle owner to take it to whatever repair shop they wish and gave independent repair shops the right to access the real-time vehicle data for diagnosis purposes. Auto dealers have sued to overturn the law, and some auto makers like Subaru and Kia have
disabled the advanced telematic systems in cars sold in Massachusetts, often without telling new customers about it. GM and Stellantis have also said they cannot comply with the Massachusetts law, and are not planning to do so because it would compromise their vehicles’ safety and cybersecurity. The Federal Trade Commission is looking into the right-to-repair issue, and President Biden has come out in support of it.
You expect me to do what, exactly?
Failure to change consumer behavior poses another major risk to the EV transition. Take charging. It requires a new consumer behavior in terms of
understanding how and when to charge, and what to do to keep an EV battery healthy. The information on the care and feeding of a battery as well as how to maximize vehicle range can resemble a manual for owning a new, exotic pet. It does not help when an automaker like Ford tells its F-150 Lightning owners they can extend their driving range by relying on the heated seats to stay warm instead of the vehicle’s climate control system.
Keeping in mind such issues, and how one might work around them, increases a driver’s cognitive load—things that must be remembered in case they must be acted on. “Automakers spent decades reducing cognitive load with dash lights instead of gauges, or automatic instead of manual transmissions,” says
University of Michigan professor emeritus John Leslie King, who has long studied human interactions with machines.
King notes, “In the early days of automobiles, drivers and chauffeurs had to monitor and be able to fix their vehicles. They were like engineers. For a time in New York City, one had to be a licensed engineer to drive a steam-powered auto. In some aspects, EV drivers return to these roots. This might change over time, but for now it is a serious issue.”

This cognitive load keeps changing as well. For instance, “common knowledge” about when EV owners should charge is not set in concrete. The long-standing mantra for charging EV batteries has been do so at home from at night when electricity rates were low and stress on the electric grid was low. Recent research from Stanford University says this is wrong, at least for Western states.
research shows that electricity rates should encourage EV charging during the day at work or at public chargers to prevent evening grid peak demand problems, which could increase by as much as 25 percent in a decade. The Wall Street Journal quotes the study’s lead author Siobhan Powell as saying if everyone were charging their EVs at night all at once, “it would cause really big problems.”
Asking EV owners to refrain from charging their vehicles at home during the night is going to be difficult, since EVs are being sold on the convenience of charging at home.
Transportation Secretary Pete Buttigieg emphasized this very point when describing how great EVs are to own, “And the main charging infrastructure that we count on is just a plug in the wall.”
Another behavior change risk relates to automakers’ desired EV owner post-purchase buying behavior. Automakers see EV (and ICE vehicle) advanced software and connectivity as a gateway to a
software-as-a-service model to generate new, recurring revenue streams across the life of the vehicle. Automakers seem to view EVs as razors through which they can sell software as the razor blades. Monetizing vehicle data and subscriptions could generate $1.5 trillion by 2030, according to McKinsey.
VW thinks that it will generate “triple-digit-millions” in future sales through selling customized subscription services, like offering autonomous driving on a pay-per-use basis. It envisions customers would be willing to
pay 7 euros per hour for the capability. Ford believes it will earn $20 billion, Stellantis some $22.5 billion and GM $20 to $25 billion from paid software-enabled vehicle features by 2030.
Already for ICE vehicles, BMW is reportedly
offering an $18 a month subscription (or $415 for “unlimited” access) for heated front seats in multiple countries, but not the U.S. as of yet. GM has started charging $1,500 for a three-year “optional” OnStar subscription on all Buick and GMC vehicles as well as the Cadillac Escalade SUV whether the owner uses it or not. And Sony and Honda have announced their luxury EV will be subscription-based, although they have not defined exactly what this means in terms of standard versus paid-for features. It would not be surprising to see it follow Mercedes’ lead. The automaker will increase the acceleration of its EQ series if an owner pays a $1,200 a year subscription fee.
Essentially, automakers are trying to normalize paying for what used to be offered as standard or even an upgrade option. Whether they will be successful is debatable, especially in the U.S. “No one is going to pay for subscriptions,” says Strategic Vision’s Edwards, who points out that
microtransactions are absolutely hated in the gaming community. Automakers risk a major consumer backlash by using them.
To get to EV at scale, each of the EV-related range, affordability, reliability and behavioral changes risks will need to be addressed by automakers and
policy makers alike. With dozens of new battery electric vehicles becoming available for sale in the next two years, potential EV buyers now have a much great range of options than previously. The automakers who manage EV risks best— along with offering compelling overall platform performance—will be the ones starting to claw back some of their hefty EV investments.
No single risk may be a deal breaker for an early EV adopter, but for skeptical ICE vehicle owners, each risk is another reason not to buy, regardless of perceived benefits offered. If EV-only families are going to be the norm, the benefits of purchasing EVs will need to be above—and the risks associated with owning will need to match or be below—those of today’s and future ICE vehicles.
In the next articles of this series, we’ll explore the changes that may be necessary to personal lifestyles to achieve 2050 climate goals.

That industry was television.
RCA president David Sarnoff’s speech at the 1939 World’s Fair was broadcast live.
Sarnoff’s speech was unusual at that time for the United States simply because it was the first time a news event was broadcast live for television. Although television technology had been in development for decades, and the BBC had been airing live programs since 1929 in the United Kingdom, competing technologies and licensing disputes kept the U.S. television market from taking off. With the World’s Fair and its theme of the World of Tomorrow, Sarnoff aimed to change that. Ten days after Sarnoff’s speech, the National Broadcasting Corporation (NBC), a fully owned subsidiary of RCA, began a regular slate of television programming, beginning with President Franklin Delano Roosevelt’s speech officially opening the fair.
RCA’s Phantom Teleceiver was the TV of tomorrow
The architecture of RCA’s pavilion at the fair was a nod to the company’s history. Designed by Skidmore & Owens, it was shaped like a radio vacuum tube. But the inside held a vision of the future.
Entering the pavilion, fairgoers encountered the Phantom Teleceiver, RCA’s latest technological wonder. This special model of the TRK-12 television receiver, which today we would call a television set or simply a TV, was housed in a cabinet constructed from DuPont’s new clear plastic, Lucite. The transparent case allowed visitors to inspect the inner workings from all sides.
An unusual aspect of the TRK-12 was its vertically positioned cathode-ray tube, which projected the image upward onto a 30.5-centimeter (12-inch) mirror on the underside of the cabinet lid. Industrial designer John Vassos, who was responsible for creating the shape of RCA’s televisions, found the size of that era’s tubes to be a unique challenge. Had the CRT been positioned horizontally, the television cabinet would have pushed out almost a meter into the room. As it was, the set was a heavyweight, standing 102 cm tall and weighing more than 91 kilograms.The image in the mirror was the reverse of that projected by the CRT, but Vassos must have decided it wasn’t a deal breaker.
According to art historian Danielle Shapiro, the author of John Vassos: Industrial Designer for Modern Life, Vassos drew on the modernist principles of streamlining to design the cabinetry for the TRK-12. In addition to contending with the size of the tube, he had to find a way to dissipate its extreme heat. He chose to integrate vents throughout the cabinet, creating a louver as a design motif. Production sets (meaning all the ones not made out of Lucite for the fair) were crafted from different shades and patterns of walnut with stripes of walnut veneer, so the overall look was of an elegant wooden box.

(If you want to see the original World’s Fair TV, it now resides at the MZTV Museum of Television, in Toronto. A clever replica, built by the Early Television Museum with an LCD screen instead of a vintage cathode-ray tube, is at the ACMI in Melbourne, Australia.)
The TRK-12 wasn’t just a TV. It was the first multimedia center. The cabinet housed the television as well as a three-band, all-wave radio and a Victrola switch to attach an optional phonograph, the sound from which would play through the radio speaker. A fidelity selector knob allowed users to switch easily among the different entertainment options, and a single knob controlled the power and volume for all settings. On the left-hand side of the console were two radio knobs (range selector and tuning control), and on the right were three dual-control knobs for the television (vertical and horizontal hold; station selection and fine tuning; and contrast and brightness).
In 1939, TV was still so novel that the owner’s manual for the TRK-12 devoted a section to explaining “How You Receive Television Pictures.”
Although the home user could select any of five different television stations and fiddle with the picture quality, a bold-faced warning in the owner’s manual cautioned that only a competent television technician should install the receiver because it had the ability to produce high voltages and electrical shocks. TV was then so novel that the manual devoted a section to explaining “How You Receive Television Pictures”: “Television reception follows the laws governing high frequency wave transmission and reception. Television waves act in many respects like light waves.” So long as you knew how light waves behaved, you were good.
In addition to designing the television sets for the fair, Vassos created two exhibits to help new users envision how these machines could fit into their homes. When David Sarnoff gave his dedication speech, for example, only a few hundred people were able to watch it live simply because so few people owned TV sets. Shapiro argues that Vassos was one of the earliest modern designers to focus on the user experience and try to alleviate the anxiety and frenzy caused by the urban environment. His design for the Radio Living Room of Today blended the latest RCA technology, including a facsimile machine, with contemporary furnishings.
In 1940, Vassos added the Radio Living Room of Tomorrow. This exhibit, dubbed the Musicorner, included dimmable fluorescent lights to allow for ideal television-watching conditions. Foreshadowing cassette recorders and CD burners was a device for recording and producing phonographs. Tasteful modular cabinets concealed the television and radio receivers, not unlike some style trends today.

Each day, thousands of visitors to the RCA pavilion encountered television, often for the first time, and watched programming on 13 TRK-12 receivers. But if television really was going to be the future, RCA had to convince consumers to buy sets. Throughout the fair’s 18-month run, the company arranged to have four models of television receivers, all designed by Vassos, available for sale at various department stores in the New York metropolitan region.
The smallest of these was the TT-5 tabletop television, which only provided a picture. It plugged into an existing radio to receive sound. The TT-5 was considered the “everyman’s version” and had a starting price of $199 ($4,300 today). Next biggest was the TRK-5, then the TRK-9, and finally the TRK-12, which sold for $600 (nearly $13,000 today). Considering that the list price of a modest new automobile in 1939 was $700 and the average annual income was $1,368, even the everyman’s television remained beyond the reach of most families.

The technical challenge of missile defense has been compared with that of hitting a bullet with a bullet. Then there is the still tougher economic challenge of using an expensive interceptor to kill a cheaper target—like hitting a lead bullet with a golden one.
Maybe trouble and money could be saved by shooting down such targets with a laser. Once the system was designed, built, and paid for, the cost per shot would be low. Such considerations led planners at the Pentagon to seek a solution from Lockheed Martin, which has just delivered a 300-kilowatt laser to the U.S. Army. The new weapon combines the output of a large bundle of fiber lasers of varying frequencies to form a single beam of white light. This laser has been undergoing tests in the lab, and it should see its first field trials sometime in 2023. General Atomics, a military contractor in San Diego, is also developing a laser of this power for the Army based on what’s known as the distributed-gain design, which has a single aperture.
Both systems offer the prospect of being inexpensive to use. The electric bill itself would range “from US $5 to $10,” for a pulse lasting a few seconds, says Michael Perry, the vice president in charge of laser systems for General Atomics.
Why are we getting ray guns only now, more than a century after H.G. Wells imagined them in his sci-fi novel The War of the Worlds? Put it down partly to the rising demand for cheap antimissile defense, but it’s mainly the result of technical advances in high-energy lasers.
The old standby for powerful lasers employed chemical reactions in flowing gas. That method was clumsy, heavy, and dangerous, and the laser itself became a flammable target for enemies to attack. The advantage was that these chemical lasers could be made immensely powerful, a far cry from the puny pulsed ruby lasers that wowed observers back in the 1960s by punching holes in razor blades (at power levels jocularly measured in “gillettes”).
“With lasers, if you can see it, you can kill it.” —Robert Afzal, Lockheed Martin
By 2014, fiber lasers had reached the point where they could be considered for weapons, and one 30-kW model was installed on the USS Ponce, where it demonstrated the ability to shoot down speedboats and small drones at relatively close range. The 300-kW fiber lasers being employed now in the two Army projects emit about 100 kW in optical power, enough to burn through much heftier targets (not to mention quite a few gillettes) at considerable distances.
“A laser of that class can be effective against a wide variety of targets, including cruise missiles, mortars, UAVs, and aircraft,” says Perry. “But not reentry vehicles [launched by ballistic missiles].” Those are the warheads, and to ward them off, he says, you’d probably have to hit the rocket when it’s still in the boost phase, which would mean placing your laser in orbit. Laser tech is still far from performing such a feat.
Even so, these futuristic weapons will no doubt find plenty of applications in today’s world. Israel made news in April by field-testing an airborne antimissile laser called Iron Beam, a play on the name Iron Dome, the missile system it has used to down rockets fired from Gaza. The laser system, reportedly rated at about 100 kW, is still not in service and hasn’t seen combat, but one day it may be able to replace some, if not all, of Iron Dome’s missiles with photons. Other countries have similar capabilities, or say they do. In May, Russia said it had used a laser to incinerate a Ukrainian drone from 5 kilometers away, a claim that Ukraine’s president, Volodymyr Zelenskyy, derided.
Not all ray guns must be lasers, though. In March, Taiwan News reported that Chinese researchers had built a microwave weapon that in principle could be placed in orbit from where its 5-megawatt pulses could fry the electronic heart of an enemy satellite. But making such a machine in the lab is quite different from operating it in the field, not to mention in outer space, where supplying power and removing waste heat constitute major problems.
Because lasers performance falls off in bad weather, they can’t be relied on by themselves to defend critically important targets. They must instead be paired with kinetic weapons—missiles or bullets—to create a layered defense system.
“With lasers, if you can see it, you can kill it; typically rain and snow are not big deterrents,” says Robert Afzal, an expert on lasers at Lockheed Martin. “But a thundercloud—that’s hard.”
Afzal says that the higher up a laser is placed, the less interference it will face, but there is a trade-off. “With an airplane you have the least amount of resources—least volume, least weight—that is available to you. On a ship, you have a lot more resources available, but you’re in the maritime atmosphere, which is pretty hazy, so you may need a lot more power to get to the target. And the Army is in between: It deals with closer threats, like rockets and mortars, and they need a deep magazine, because they deal with a lot more targets.”
In every case, the point is to use expensive antimissile missiles only when you must. Israel opted to pursue laser weapons in part because its Iron Dome missiles cost so much more than the unguided, largely homemade rockets they defend against. Some of the military drones that Russia and Ukraine are now flying wouldn’t break the budget of the better-heeled sort of hobbyist. And it would be a Pyrrhic victory indeed to shoot them from the sky with projectiles so costly that you went broke.

Three days before astronauts left on Apollo 8, the first-ever flight around the moon, NASA’s safety chief, Jerome Lederer, gave a speech that was at once reassuring and chilling. Yes, he said, the United States’ moon program was safe and well-planned—but even so, “Apollo 8 has 5,600,000 parts and one and one half million systems, subsystems, and assemblies. Even if all functioned with 99.9 percent reliability, we could expect 5,600 defects.”
The mission, in December 1968, was nearly flawless—a prelude to the Apollo 11 landing the next summer. But even today, half a century later, engineers wrestle with the sheer complexity of the machines they build to go to space. NASA’s Artemis I, its Space Launch System rocket mandated by Congress in 2010, endured a host of delays before it finally launched in November 2022. And Elon Musk’sSpaceX may be lauded for its engineering acumen, but it struggled for six years before its first successful flight into orbit.
Relativity envisions 3D-printing facilities someday on the Martian surface, fabricating much of what people from Earth would need to live there.
Is there a better way? An upstart company called Relativity Space is about to try one. Its Terran 1 rocket, the company says, has about a tenth as many parts as comparable launch vehicles do, because it is made through 3D printing. Instead of bending metal and milling and welding, engineers program a robot to deposit layers of metal alloy in place.
Relativity’s first rocket, the company says, is ready to go from launch complex 16 at Cape Canaveral, Fla. When it happens, possibly later this month, the company says it will stream the liftoff on YouTube.

“Over 85 percent of the rocket by mass is 3D printed,” said Scott Van Vliet, Relativity’s head of software engineering. “And what’s really cool is not only are we reducing the amount of parts and labor that go into building one of these vehicles over time, but we’re also reducing the complexity, we’re reducing the chance of failure when you reduce the part count, and you streamline the build process.”
Relativity says it can put together a Terran rocket in two months, compared to two years for some conventionally built ones. The speed and cost of making a prototype—say, for wind-tunnel testing—are reduced because you tell the printer to make a scaled-down model. There is less waste because the process is additive. And if something needs to be modified, you reprogram the 3D printer instead of slow, expensive retooling.
“If you walk into any rocket factory today other than ours,” said Josh Brost, the company’s head of business development, “you still will see hundreds of thousands of parts coming from thousands of vendors, and still being assembled using lots of touch labor and lots of big-fix tools.”
Terran 1, rated as capable of putting a 1,250-kilogram payload in low Earth orbit, is mainly intended as a test bed. Relativity has signed up a variety of future customers for satellite launches, but the first Terran 1 (“Terran” means “earthling”) will not carry a paying customer’s satellite. The first flight has been given the playful name “Good Luck, Have Fun”—GLHF for short. Eventually, if things are going well, Relativity will build a larger booster, called Terran R, which the company hopes will compete with the SpaceX Falcon 9 for launches of up to 20,000 kg. Relativity says the Terran R should be fully reusable, including the upper stage—something that other commercial launch companies have not accomplished. In current renderings, the rocket is, as the company puts it, “inspired by nature,” shaped to slice through the atmosphere as it ascends and comes back for recovery.
A number of Relativity’s top people came from Musk’s SpaceX or Jeff Bezos’s space company, Blue Origin, and, like Musk, they say their vision is a permanent presence on Mars. Brost calls it “the long-term North Star for us.” They say they can envision 3D-printing facilities someday on the Martian surface, fabricating much of what people from Earth would need to live there. “For that to happen,” says Brost, “you need to have manufacturing capabilities that are autonomous and incredibly flexible.”
Relativity’s fourth-generation Stargate 3D printer.Relativity
Just how Relativity will do all these things is a work in progress. The company says its 3D technology will help it work iteratively—finding mistakes as it goes, then correcting them as it prints the next rocket, and the next, and so on.
“In traditional manufacturing, you have to do a ton of work up front and have a lot of the design features done well ahead of time,” says Van Vliet. “You have to invest in fixed tooling that can often take years to build before you’ve actually developed an article for your launch vehicle. With 3D printing, additive manufacturing, we get to building something very, very quickly.”
The next step is to get the first rocket off the pad. Will it succeed? Brost says a key test will be getting through max q—the point of maximum dynamic pressure on the rocket as it accelerates through the atmosphere before the air around it thins out.
“If you look at history, at new space companies doing large rockets, there’s not a single one that’s done their first rocket on their first try. It would be quite an achievement if we were able to achieve orbit on our inaugural launch,” says Brost.
“I’ve been to many launches in my career,” he says, “and it never gets less exciting or nerve wracking to me.”

NASA’s Artemis I mission launched early in the predawn hours this morning, at 1:04 a.m. eastern time, carrying with it the hopes of a space program aiming now to land American astronauts back on the moon. The Orion spacecraft now on its way to the moon also carries with it a lot of CubeSat-size science. (As of press time, some satellites have even begun to tweet.)
And while the objective of Artemis I is to show that the launch system and spacecraft can make a trip to the moon and return safely to Earth, the mission is also a unique opportunity to send a whole spacecraft-load of science into deep space. In addition to the interior of the Orion capsule itself, there are enough nooks and crannies to handle a fair number of CubeSats, and NASA has packed as many experiments as it can into the mission. From radiation phantoms to solar sails to algae to a lunar surface payload, Artemis I has a lot going on.
Most of the variety of the science on Artemis I comes in the form of CubeSats, little satellites that are each the size of a large shoebox. The CubeSats are tucked snugly into berths inside the Orion stage adapter, which is the bit that connects the interim cryogenic propulsion stage to the ESA service module and Orion. Once the propulsion stage lifts Orion out of Earth orbit and pushes it toward the moon, the stage and adapter will separate from Orion, and the CubeSats will launch themselves.

While the CubeSats look identical when packed up, each one is totally unique in both hardware and software, with different destinations and mission objectives. There are 10 in total (three weren’t ready in time for launch, which is why there are a couple of empty slots in the image above).
Here is what each one is and does:
While the CubeSats head off to do their own thing, inside the Orion capsule itself will be the temporary home of a trio of mannequins. The first, a male-bodied version provided by NASA, is named Commander Moonikin Campos, after NASA electrical engineer Arturo Campos, who was the guy who wrote the procedures that allowed the Apollo 13 command module to steal power from the lunar module’s batteries, one of many actions that saved the Apollo 13 crew.

Moonikin Campos will spend the mission in the Orion commander’s seat, wearing an Orion crew survival system suit. Essentially itself a spacecraft, the suit is able to sustain its occupant for up to six days if necessary. Moonikin Campos’s job will be to pretend to be an astronaut, and sensors inside him will measure radiation, acceleration, and vibration to help NASA prepare to launch human astronauts in the next Artemis mission.

Accompanying Moonikin Campos are two female-bodied mannequins, named Helga and Zohar, developed by the German Aerospace Center (DLR) along with the Israel Space Agency. These are more accurately called “anthropomorphic phantoms,” and their job is to provide a detailed recording of the radiation environment inside the capsule over the course of the mission. The phantoms are female because women have more radiation-sensitive tissue than men. Both Helga and Zohar have over 6,000 tiny radiation detectors placed throughout their artificial bodies, but Zohar will be wearing an AstroRad radiation protection vest to measure how effective it is.
NASA’s Biology Experiment-1 is transferred to the Orion team.NASA/KSC
The final science experiment to fly onboard Orion is NASA’s Biology Experiment-1. The experiment is really just seeing what time in deep space does to some specific kinds of biology, so all that has to happen is for Orion to successfully haul some packages of sample tubes around the moon and back. Samples include:
Plant seeds to characterize how spaceflight affects nutrient stores
Photosynthetic algae to identify genes that contribute to its survival in deep space
Aspergillus fungus to investigate radioprotective effects of melanin and DNA damage response
Yeast used as a model organism to identify genes that enable adaptations to conditions in both low Earth orbit and deep space
There is some concern that because of the extensive delays with the Artemis launch, the CubeSats have been sitting so long that their batteries may have run down. Some of the CubeSats could be recharged, but for others, recharging was judged to be so risky that they were left alone. Even for CubeSats that don’t start right up, though, it’s possible that after deployment, their solar panels will be able to get them going. But at this point, there’s still a lot of uncertainty, and the CubeSats’ earthbound science teams are now pinning their hopes on everything going well after launch.
For the rest of the science payloads, success mostly means Orion returning to Earth safe and sound, which will also be a success for the Artemis I mission as a whole. And assuming it does so, there will be a lot more science to come.

People find it amazing that some users spend thousands or millions of dollars on a single NFT-based image of a monkey or other token, but you can simply take a screenshot for free. So here we share some freuently asked question about NFTs.
1) What is an NFT?
NFT stands for non-fungible token, which is a cryptographic token on a blockchain with unique identification codes that distinguish it from other tokens. NFTs are unique and not interchangeable, which means no two NFTs are the same. NFTs can be a unique artwork, GIF, Images, videos, Audio album. in-game items, collectibles etc.
2) What is Blockchain?
A blockchain is a distributed digital ledger that allows for the secure storage of data. By recording any kind of information—such as bank account transactions, the ownership of Non-Fungible Tokens (NFTs), or Decentralized Finance (DeFi) smart contracts—in one place, and distributing it to many different computers, blockchains ensure that data can’t be manipulated without everyone in the system being aware.
3) What makes an NFT valuable?
The value of an NFT comes from its ability to be traded freely and securely on the blockchain, which is not possible with other current digital ownership solutionsThe NFT points to its location on the blockchain, but doesn’t necessarily contain the digital property. For example, if you replace one bitcoin with another, you will still have the same thing. If you buy a non-fungible item, such as a movie ticket, it is impossible to replace it with any other movie ticket because each ticket is unique to a specific time and place.
4) How do NFTs work?
One of the unique characteristics of non-fungible tokens (NFTs) is that they can be tokenised to create a digital certificate of ownership that can be bought, sold and traded on the blockchain.
As with crypto-currency, records of who owns what are stored on a ledger that is maintained by thousands of computers around the world. These records can’t be forged because the whole system operates on an open-source network.
NFTs also contain smart contracts—small computer programs that run on the blockchain—that give the artist, for example, a cut of any future sale of the token.
5) What’s the connection between NFTs and cryptocurrency?
Non-fungible tokens (NFTs) aren't cryptocurrencies, but they do use blockchain technology. Many NFTs are based on Ethereum, where the blockchain serves as a ledger for all the transactions related to said NFT and the properties it represents.5) How to make an NFT?
Anyone can create an NFT. All you need is a digital wallet, some ethereum tokens and a connection to an NFT marketplace where you’ll be able to upload and sell your creations
6) How to validate the authencity of an NFT?
When you purchase a stock in NFT, that purchase is recorded on the blockchain—the bitcoin ledger of transactions—and that entry acts as your proof of ownership.
7) How is an NFT valued? What are the most expensive NFTs?
The value of an NFT varies a lot based on the digital asset up for grabs. People use NFTs to trade and sell digital art, so when creating an NFT, you should consider the popularity of your digital artwork along with historical statistics.
In the year 2021, a digital artist called Pak created an artwork called The Merge. It was sold on the Nifty Gateway NFT market for $91.8 million.
8) Can NFTs be used as an investment?
Non-fungible tokens can be used in investment opportunities. One can purchase an NFT and resell it at a profit. Certain NFT marketplaces let sellers of NFTs keep a percentage of the profits from sales of the assets they create.
9) Will NFTs be the future of art and collectibles?
Many people want to buy NFTs because it lets them support the arts and own something cool from their favorite musicians, brands, and celebrities. NFTs also give artists an opportunity to program in continual royalties if someone buys their work. Galleries see this as a way to reach new buyers interested in art.
10) How do we buy an NFTs?
There are many places to buy digital assets, like opensea and their policies vary. On top shot, for instance, you sign up for a waitlist that can be thousands of people long. When a digital asset goes on sale, you are occasionally chosen to purchase it.
11) Can i mint NFT for free?
To mint an NFT token, you must pay some amount of gas fee to process the transaction on the Etherum blockchain, but you can mint your NFT on a different blockchain called Polygon to avoid paying gas fees. This option is available on OpenSea and this simply denotes that your NFT will only be able to trade using Polygon's blockchain and not Etherum's blockchain. Mintable allows you to mint NFTs for free without paying any gas fees.
12) Do i own an NFT if i screenshot it?
The answer is no. Non-Fungible Tokens are minted on the blockchain using cryptocurrencies such as Etherum, Solana, Polygon, and so on. Once a Non-Fungible Token is minted, the transaction is recorded on the blockchain and the contract or license is awarded to whoever has that Non-Fungible Token in their wallet.
12) Why are people investing so much in NFT?
Non-fungible tokens have gained the hearts of people around the world, and they have given digital creators the recognition they deserve. One of the remarkable things about non-fungible tokens is that you can take a screenshot of one, but you don’t own it. This is because when a non-fungible token is created, then the transaction is stored on the blockchain, and the license or contract to hold such a token is awarded to the person owning the token in their digital wallet.
You can sell your work and creations by attaching a license to it on the blockchain, where its ownership can be transferred. This lets you get exposure without losing full ownership of your work. Some of the most successful projects include Cryptopunks, Bored Ape Yatch Club NFTs, SandBox, World of Women and so on. These NFT projects have gained popularity globally and are owned by celebrities and other successful entrepreneurs. Owning one of these NFTs gives you an automatic ticket to exclusive business meetings and life-changing connections.

Andrew Ng has serious street cred in artificial intelligence. He pioneered the use of graphics processing units (GPUs) to train deep learning models in the late 2000s with his students at Stanford University, cofounded Google Brain in 2011, and then served for three years as chief scientist for Baidu, where he helped build the Chinese tech giant’s AI group. So when he says he has identified the next big shift in artificial intelligence, people listen. And that’s what he told IEEE Spectrum in an exclusive Q&A.
Ng’s current efforts are focused on his company
Landing AI, which built a platform called LandingLens to help manufacturers improve visual inspection with computer vision. He has also become something of an evangelist for what he calls the data-centric AI movement, which he says can yield “small data” solutions to big issues in AI, including model efficiency, accuracy, and bias.
The great advances in deep learning over the past decade or so have been powered by ever-bigger models crunching ever-bigger amounts of data. Some people argue that that’s an unsustainable trajectory. Do you agree that it can’t go on that way?
Andrew Ng: This is a big question. We’ve seen foundation models in NLP [natural language processing]. I’m excited about NLP models getting even bigger, and also about the potential of building foundation models in computer vision. I think there’s lots of signal to still be exploited in video: We have not been able to build foundation models yet for video because of compute bandwidth and the cost of processing video, as opposed to tokenized text. So I think that this engine of scaling up deep learning algorithms, which has been running for something like 15 years now, still has steam in it. Having said that, it only applies to certain problems, and there’s a set of other problems that need small data solutions.
When you say you want a foundation model for computer vision, what do you mean by that?
Ng: This is a term coined by Percy Liang and some of my friends at Stanford to refer to very large models, trained on very large data sets, that can be tuned for specific applications. For example, GPT-3 is an example of a foundation model [for NLP]. Foundation models offer a lot of promise as a new paradigm in developing machine learning applications, but also challenges in terms of making sure that they’re reasonably fair and free from bias, especially if many of us will be building on top of them.
What needs to happen for someone to build a foundation model for video?
Ng: I think there is a scalability problem. The compute power needed to process the large volume of images for video is significant, and I think that’s why foundation models have arisen first in NLP. Many researchers are working on this, and I think we’re seeing early signs of such models being developed in computer vision. But I’m confident that if a semiconductor maker gave us 10 times more processor power, we could easily find 10 times more video to build such models for vision.
Having said that, a lot of what’s happened over the past decade is that deep learning has happened in consumer-facing companies that have large user bases, sometimes billions of users, and therefore very large data sets. While that paradigm of machine learning has driven a lot of economic value in consumer software, I find that that recipe of scale doesn’t work for other industries.
It’s funny to hear you say that, because your early work was at a consumer-facing company with millions of users.
Ng: Over a decade ago, when I proposed starting the Google Brain project to use Google’s compute infrastructure to build very large neural networks, it was a controversial step. One very senior person pulled me aside and warned me that starting Google Brain would be bad for my career. I think he felt that the action couldn’t just be in scaling up, and that I should instead focus on architecture innovation.
“In many industries where giant data sets simply don’t exist, I think the focus has to shift from big data to good data. Having 50 thoughtfully engineered examples can be sufficient to explain to the neural network what you want it to learn.”
—Andrew Ng, CEO & Founder, Landing AI
I remember when my students and I published the first
NeurIPS workshop paper advocating using CUDA, a platform for processing on GPUs, for deep learning—a different senior person in AI sat me down and said, “CUDA is really complicated to program. As a programming paradigm, this seems like too much work.” I did manage to convince him; the other person I did not convince.
I expect they’re both convinced now.
Ng: I think so, yes.
Over the past year as I’ve been speaking to people about the data-centric AI movement, I’ve been getting flashbacks to when I was speaking to people about deep learning and scalability 10 or 15 years ago. In the past year, I’ve been getting the same mix of “there’s nothing new here” and “this seems like the wrong direction.”
How do you define data-centric AI, and why do you consider it a movement?
Ng: Data-centric AI is the discipline of systematically engineering the data needed to successfully build an AI system. For an AI system, you have to implement some algorithm, say a neural network, in code and then train it on your data set. The dominant paradigm over the last decade was to download the data set while you focus on improving the code. Thanks to that paradigm, over the last decade deep learning networks have improved significantly, to the point where for a lot of applications the code—the neural network architecture—is basically a solved problem. So for many practical applications, it’s now more productive to hold the neural network architecture fixed, and instead find ways to improve the data.
When I started speaking about this, there were many practitioners who, completely appropriately, raised their hands and said, “Yes, we’ve been doing this for 20 years.” This is the time to take the things that some individuals have been doing intuitively and make it a systematic engineering discipline.
The data-centric AI movement is much bigger than one company or group of researchers. My collaborators and I organized a
data-centric AI workshop at NeurIPS, and I was really delighted at the number of authors and presenters that showed up.
You often talk about companies or institutions that have only a small amount of data to work with. How can data-centric AI help them?
Ng: You hear a lot about vision systems built with millions of images—I once built a face recognition system using 350 million images. Architectures built for hundreds of millions of images don’t work with only 50 images. But it turns out, if you have 50 really good examples, you can build something valuable, like a defect-inspection system. In many industries where giant data sets simply don’t exist, I think the focus has to shift from big data to good data. Having 50 thoughtfully engineered examples can be sufficient to explain to the neural network what you want it to learn.
When you talk about training a model with just 50 images, does that really mean you’re taking an existing model that was trained on a very large data set and fine-tuning it? Or do you mean a brand new model that’s designed to learn only from that small data set?
Ng: Let me describe what Landing AI does. When doing visual inspection for manufacturers, we often use our own flavor of RetinaNet. It is a pretrained model. Having said that, the pretraining is a small piece of the puzzle. What’s a bigger piece of the puzzle is providing tools that enable the manufacturer to pick the right set of images [to use for fine-tuning] and label them in a consistent way. There’s a very practical problem we’ve seen spanning vision, NLP, and speech, where even human annotators don’t agree on the appropriate label. For big data applications, the common response has been: If the data is noisy, let’s just get a lot of data and the algorithm will average over it. But if you can develop tools that flag where the data’s inconsistent and give you a very targeted way to improve the consistency of the data, that turns out to be a more efficient way to get a high-performing system.
“Collecting more data often helps, but if you try to collect more data for everything, that can be a very expensive activity.”
For example, if you have 10,000 images where 30 images are of one class, and those 30 images are labeled inconsistently, one of the things we do is build tools to draw your attention to the subset of data that’s inconsistent. So you can very quickly relabel those images to be more consistent, and this leads to improvement in performance.
Could this focus on high-quality data help with bias in data sets? If you’re able to curate the data more before training?
Ng: Very much so. Many researchers have pointed out that biased data is one factor among many leading to biased systems. There have been many thoughtful efforts to engineer the data. At the NeurIPS workshop, Olga Russakovsky gave a really nice talk on this. At the main NeurIPS conference, I also really enjoyed Mary Gray’s presentation, which touched on how data-centric AI is one piece of the solution, but not the entire solution. New tools like Datasheets for Datasets also seem like an important piece of the puzzle.
One of the powerful tools that data-centric AI gives us is the ability to engineer a subset of the data. Imagine training a machine-learning system and finding that its performance is okay for most of the data set, but its performance is biased for just a subset of the data. If you try to change the whole neural network architecture to improve the performance on just that subset, it’s quite difficult. But if you can engineer a subset of the data you can address the problem in a much more targeted way.
When you talk about engineering the data, what do you mean exactly?
Ng: In AI, data cleaning is important, but the way the data has been cleaned has often been in very manual ways. In computer vision, someone may visualize images through a Jupyter notebook and maybe spot the problem, and maybe fix it. But I’m excited about tools that allow you to have a very large data set, tools that draw your attention quickly and efficiently to the subset of data where, say, the labels are noisy. Or to quickly bring your attention to the one class among 100 classes where it would benefit you to collect more data. Collecting more data often helps, but if you try to collect more data for everything, that can be a very expensive activity.
For example, I once figured out that a speech-recognition system was performing poorly when there was car noise in the background. Knowing that allowed me to collect more data with car noise in the background, rather than trying to collect more data for everything, which would have been expensive and slow.
What about using synthetic data, is that often a good solution?
Ng: I think synthetic data is an important tool in the tool chest of data-centric AI. At the NeurIPS workshop, Anima Anandkumar gave a great talk that touched on synthetic data. I think there are important uses of synthetic data that go beyond just being a preprocessing step for increasing the data set for a learning algorithm. I’d love to see more tools to let developers use synthetic data generation as part of the closed loop of iterative machine learning development.
Do you mean that synthetic data would allow you to try the model on more data sets?
Ng: Not really. Here’s an example. Let’s say you’re trying to detect defects in a smartphone casing. There are many different types of defects on smartphones. It could be a scratch, a dent, pit marks, discoloration of the material, other types of blemishes. If you train the model and then find through error analysis that it’s doing well overall but it’s performing poorly on pit marks, then synthetic data generation allows you to address the problem in a more targeted way. You could generate more data just for the pit-mark category.
“In the consumer software Internet, we could train a handful of machine-learning models to serve a billion users. In manufacturing, you might have 10,000 manufacturers building 10,000 custom AI models.”
Synthetic data generation is a very powerful tool, but there are many simpler tools that I will often try first. Such as data augmentation, improving labeling consistency, or just asking a factory to collect more data.
To make these issues more concrete, can you walk me through an example? When a company approaches Landing AI and says it has a problem with visual inspection, how do you onboard them and work toward deployment?
Ng: When a customer approaches us we usually have a conversation about their inspection problem and look at a few images to verify that the problem is feasible with computer vision. Assuming it is, we ask them to upload the data to the LandingLens platform. We often advise them on the methodology of data-centric AI and help them label the data.
One of the foci of Landing AI is to empower manufacturing companies to do the machine learning work themselves. A lot of our work is making sure the software is fast and easy to use. Through the iterative process of machine learning development, we advise customers on things like how to train models on the platform, when and how to improve the labeling of data so the performance of the model improves. Our training and software supports them all the way through deploying the trained model to an edge device in the factory.
How do you deal with changing needs? If products change or lighting conditions change in the factory, can the model keep up?
Ng: It varies by manufacturer. There is data drift in many contexts. But there are some manufacturers that have been running the same manufacturing line for 20 years now with few changes, so they don’t expect changes in the next five years. Those stable environments make things easier. For other manufacturers, we provide tools to flag when there’s a significant data-drift issue. I find it really important to empower manufacturing customers to correct data, retrain, and update the model. Because if something changes and it’s 3 a.m. in the United States, I want them to be able to adapt their learning algorithm right away to maintain operations.
In the consumer software Internet, we could train a handful of machine-learning models to serve a billion users. In manufacturing, you might have 10,000 manufacturers building 10,000 custom AI models. The challenge is, how do you do that without Landing AI having to hire 10,000 machine learning specialists?
So you’re saying that to make it scale, you have to empower customers to do a lot of the training and other work.
Ng: Yes, exactly! This is an industry-wide problem in AI, not just in manufacturing. Look at health care. Every hospital has its own slightly different format for electronic health records. How can every hospital train its own custom AI model? Expecting every hospital’s IT personnel to invent new neural-network architectures is unrealistic. The only way out of this dilemma is to build tools that empower the customers to build their own models by giving them tools to engineer the data and express their domain knowledge. That’s what Landing AI is executing in computer vision, and the field of AI needs other teams to execute this in other domains.
Is there anything else you think it’s important for people to understand about the work you’re doing or the data-centric AI movement?
Ng: In the last decade, the biggest shift in AI was a shift to deep learning. I think it’s quite possible that in this decade the biggest shift will be to data-centric AI. With the maturity of today’s neural network architectures, I think for a lot of the practical applications the bottleneck will be whether we can efficiently get the data we need to develop systems that work well. The data-centric AI movement has tremendous energy and momentum across the whole community. I hope more researchers and developers will jump in and work on it.
Apptronik, a Texas-based robotics company with its roots in the Human Centered Robotics Lab at University of Texas at Austin, has spent the last few years working toward a practical, general-purpose humanoid robot. By designing its robot (called Apollo) completely from the ground up, including electronics and actuators, Apptronik is hoping that it’ll be able to deliver something affordable, reliable, and broadly useful. But at the moment, the most successful robots are not generalized systems—they’re uni-taskers, robots that can do one specific task very well but more or less nothing else. A general purpose robot, especially one in a human form factor, would have enormous potential. But the challenge is enormous, too.
So why does Apptronik believe that it has the answer to general-purpose humanoid robots with Apollo? To find out, we spoke with Apptronik’s founders, CEO Jeff Cardenas and CTO Nick Paine.
IEEE Spectrum: Why are you developing a general-purpose robot when the most successful robots in the supply chain focus on specific tasks?
Nick Paine: It’s about our level of ambition. A specialized tool is always going to beat a general tool at one task, but if you’re trying to solve 10 tasks, or 100 tasks, or 1,000 tasks, it’s more logical to put your effort into a single versatile hardware platform with specialized software that solves a myriad of different problems.
How do you know that you’ve reached an inflection point where building a general-purpose commercial humanoid is now realistic, when it wasn’t before?
Paine: There are a number of different things. For one, Moore’s Law has slowed down, but computers are evolving in a way that has helped advance the complexity of algorithms that can be deployed on mobile systems. Also, there are new algorithms that have been developed recently that have enabled advancements in legged locomotion, machine vision, and manipulation. And along with algorithmic improvements, there have been sensing improvements. All of this has influenced the ability to design these types of legged systems for unstructured environments.
Jeff Cardenas: I think it’s taken decades for it to be the right time. After many, many iterations as a company, we’ve gotten to the point where we’ve said, “Okay, we see all the pieces to where we believe we can build a robust, capable, affordable system that can really go out and do work.” It’s still the beginning, but we’re now at an inflection point where there’s demand from the market, and we can get these out into the world.
The reason that I got into robotics is that I was sick of seeing robots just dancing all the time. I really wanted to make robots that could be useful in the world. —Nick Paine, CTO of Apptronik
Why did you need to develop and test 30 different actuators for Apollo, and how did you know that the 30th actuator was the right one?
Paine: The reason for the variety was that we take a first-principles approach to designing robotic systems. The way you control the system really impacts how you design the system, and that goes all the way down to the actuators. A certain type of actuator is not always the silver bullet: Every actuator has its strengths and weaknesses, and we’ve explored that space to understand the limitations of physics to guide us toward the right solutions.
With your focus on making a system that’s affordable, how much are you relying on software to help you minimize hardware costs?
Paine: Some groups have tried masking the deficiencies of cheap, low-quality hardware with software. That’s not at all the approach we’re taking. We are leaning on our experience building these kinds of systems over the years from a first-principles approach. Building from the core requirements for this type of system, we’ve found a solution that hits our performance targets while also being far more mass producible compared to anything we’ve seen in this space previously. We’re really excited about the solution that we’ve found.
How much effort are you putting into software at this stage? How will you teach Apollo to do useful things?
Paine: There are some basic applications that we need to solve for Apollo to be fundamentally useful. It needs to be able to walk around, to use its upper body and its arms to interact with the environment. Those are the core capabilities that we’re working on, and once those are at a certain level of maturity, that’s where we can open up the platform for third-party application developers to build on top of that.
Cardenas: If you look at Willow Garage with the PR2, they had a similar approach, which was to build a solid hardware platform, create a powerful API, and then let others build applications on it. But then you’re really putting your destiny in the hands of other developers. One of the things that we learned from that is if you want to enable that future, you have to prove that initial utility. So what we’re doing is handling the full-stack development on the initial applications, which will be targeting supply chain and logistics.
NASA officials have expressed their interest in Apptronik developing “technology and talent that will sustain us through the Artemis program and looking forward to Mars.”
“In robotics, seeing is believing. You can say whatever you want, but you really have to prove what you can do, and that’s been our focus. We want to show versus tell.” —Jeff Cardenas, CEO of Apptronik
Apptronik plans for the alpha version of Apollo to be ready in March, in time for a sneak peak for a small audience at SXSW. From there, the alpha Apollos will go through pilots as Apptronik collects feedback to develop a beta version that will begin larger deployments. The company expects these programs to lead to full a gamma version and full production runs by the end of 2024.

Transmission of respiratory pathogens has always occurred, yet in the past we have reserved mask-wearing for the most high-risk situations, such as around those with tuberculosis or severe immunosuppression. Now it appears that social connection has been sacrificed permanently in favour of some victory in the battle between humanity and microbes. This may turn out to be the most important war humans have ever faced. Yet if it is worth sacrificing the ability to see another person’s face, why are only healthcare workers doing it?

The 1985 action-adventure TV series MacGyver showcased the life of Angus MacGyver, a secret agent who solved problems using items he had on hand. For example, in one episode, he made a heat shield out of used refrigerator parts. In another, he made a fishing lure with a candy wrapper. More than three decades later, the show still has relevance. The verb MacGyver, to design something in a makeshift or creative way, was added to the Oxford English Dictionary in 2015.
Try putting your MacGyver skills to the test: If you were handed some CDs, what would you make out of them? Reflective wall art, mosaic ornaments, or a wind chime, perhaps? What about a miniaturized water treatment plant?
This is what a team of engineers and researchers are doing at Eden Tech, a company based in Paris, France, that specializes in the development of microfluidics technology. Within their R&D department, Eden Cleantech, they are developing a compact, energy-saving water treatment system to help tackle the growing presence of micropollutants in wastewater. To analyze the performance of their AKVO system (named after the Latin word for water, aqua), which is made from CDs, Eden Tech turned to multiphysics simulation.
Contaminants of Emerging Concern
“There are many ways micropollutants make it into wastewater,” says Wei Zhao, a senior chemical engineer and chief product officer at Eden Tech. The rise of these microscopic chemicals in wastewater worldwide is a result of daily human activities. For instance, when we wash our hands with soap, wipe down our sinks with cleaning supplies, or flush medications out of our bodies, various chemicals are washed down the drain and end up in sewage systems. Some of these chemicals are classified as micropollutants, or contaminants of emerging concern (CECs). In addition to domestic waste, agricultural pollution and industrial waste are also to blame for the rise of micropollutants in our waterways.
Micropollutants are added to the world’s lakes, rivers, and streams every day. Many conventional wastewater treatment plants are not equipped to remove these potentially hazardous chemical residues from wastewater.
Unfortunately, many conventional wastewater treatment plants (WWTP, Figure 1) are not designed to remove these contaminants. Therefore, they are often reintroduced to various bodies of water, including rivers, streams, lakes, and even drinking water. Although the risk they pose to human and environmental health is not fully understood, the increasing number of pollution found in the world’s bodies of water is of concern.
With this growing problem in mind, Eden Tech got to work on developing a solution, thus AKVO was born. Each AKVO CD core is designed to have a diameter of 15 cm and a thickness of 2 mm. One AKVO cartridge is composed of stacked CDs of varying numbers, combined to create a miniaturized factory. One AKVO core treats 0.5 to 2 m3 water/day, which means that an AKVO system composed of 10,000 CDs can treat average municipal needs. This raises the question: How can a device made from CDs decontaminate water?
A Sustainable Wastewater Treatment Method
A single AKVO system (Figure 2) consists of a customizable cartridge filled with stacked CDs that each have a microchannel network inscribed on them. It removes undesirable elements in wastewater, like micropollutants, by circulating the water in its microchannel networks. These networks are energy savvy because they only require a small pump to circulate and clean large volumes of water. The AKVO system’s cartridges can easily be replaced, with Eden Tech taking care of their recycling.
AKVO’s revolutionary design combines photocatalysis and microfluidics into one compact system. Photocatalysis, a type of advanced oxidation process (AOP), is a fast and effective way to remove micropollutants from wastewater. Compared to other AOPs, it is considered safer and more sustainable because it is powered by a light source. During photocatalysis, light is absorbed by photocatalysts that have the ability to create electron-hole pairs, which generate free hydroxyl radicals that are able to react with target pollutants and degrade them. The combination of photocatalysis and microfluidics for the treatment of wastewater has never been done before. “It is a very ambitious project,” said Zhao. “We wanted to develop an innovative method in order to provide an environmentally friendly, efficient way to treat wastewater.” AKVO’s current design did not come easy, as Zhao and his team faced several design challenges along the way.
Overcoming Design Challenges
When in use, a chemical agent (catalyst) and wastewater are dispersed through AKVO’s microchannel walls. The purpose of the catalyst, titanium dioxide in this case, is to react with the micropollutants and help remove them in the process. However, AKVO’s fast flow rate complicates this action. “The big problem is that [AKVO] has microchannels with fast flow rates, and sometimes when we put the chemical agent inside one of the channels’ walls, the micropollutants in the wastewater cannot react efficiently with the agent,” said Zhao. In order to increase the opportunity of contact between the micropollutants and the immobilized chemical agent, Zhao and his team opted to use a staggered herringbone micromixer (SHM) design for AKVO’s microchannel networks (Figure 3).
To analyze the performance of the SHM design to support chemical reactions for micropollutant degradation, Zhao used the COMSOL Multiphysics software.
Simulating Chemical Reactions for Micropollutant Degradation
In his work, Zhao built two different models in COMSOL Multiphysics (Figure 4), named the Explicit Surface Adsorption (ESA) model and the Converted Surface Concentration (CSC) model. Both of these models account for chemical and fluid phenomena.
In both models, Zhao found that AKVO’s SHM structure creates vortices in the flow moving through it, which enables the micropollutants and the chemical agent to have a longer reaction period and enhances the mass transfer between each fluid layer. However, the results of the ESA model displayed that the design purified about 50 percent of the micropollutants under treatment, fewer than what Zhao expected.
Unlike the ESA model (Figure 5), in the CSC model, it is assumed that there is no adsorption limitation. Therefore, as long as a micropollutant arrives at the surface of a catalyst, a reaction happens, which has been discussed in existing literature (Ref. 1). In this model, Zhao analyzed how the design performed for the degradation of six different micropollutants, including gemfibrozil, ciprofloxacin, carbamazepine, clofibric acid, bisphenol A, and acetaminophen (Figure 6). The results of this model were in line with what Zhao expected, with more than 95 percent of the micropollutants being treated.
“We are really satisfied with the results of COMSOL Multiphysics. My next steps will be focused on laboratory testing [of the AKVO prototype]. We are expecting to have our first prototype ready by the beginning of 2022,” said Zhao. The prototype will eventually be tested at hospitals and water treatment stations in the south of France.
Using simulation for this project has helped the Eden Tech team save time and money. Developing a prototype of a microfluidic system, like AKVO, is costly. To imprint microchannel networks on each of AKVO’s CDs, a microchannel photomask is needed. According to Zhao, to fabricate one photomask would cost about €3000 (3500 USD). Therefore, it is very important that they are confident that their system works well prior to its fabrication. “COMSOL Multiphysics has really helped us validate our models and our designs,” said Zhao.
Pioneer in the Treatment of Micropollutants
In 2016, Switzerland introduced legislation mandating that wastewater treatment plants remove micropollutants from wastewater. Their goal? Filter out over 80 percent of micropollutants at more than 100 Swiss WWTPs. Following their lead, many other countries are currently thinking of how they want to handle the growing presence of these contaminants in their waterways. AKVO has the potential to provide a compact, environmentally friendly way to help slow this ongoing problem.
The next time you go to throw out an old CD, or any other household item for that matter, ask yourself: What would MacGyver do? Or, better yet: What would Eden Tech do? You might be holding the building blocks for their next innovative design.

At Moffett Field in Mountain View, Calif., Lighter Than Air (LTA) Research is floating a new approach to a technology that saw its rise and fall a century ago: airships. Although airships have long since been supplanted by planes, LTA, which was founded in 2015 by CEO Alan Weston, believes that through a combination of new materials, better construction techniques, and technological advancements, airships are poised to—not reclaim the skies, certainly—but find a new niche.
Although airships never died off entirely—the
Goodyear blimps, familiar to sports fans, are proof of that—the industry was already in decline by 1937, the year of the Hindenburg disaster. By the end of World War II, airships couldn’t compete with the speed airplanes offered, and they required larger crews. Today, what airships still linger serve primarily for advertising and sightseeing.
LTA’s Pathfinder 1 carries bigger dreams than hovering over a sports stadium, however. The company sees a natural fit for airships in humanitarian and relief missions. Airships can stay aloft for long periods of time, in case ground conditions aren’t ideal, have a long range, and carry significant payloads, according to
Carl Taussig, LTA’s chief technical officer.
Pathfinder’s cigar-shaped envelope is just over 120 meters in length and 20 meters in diameter. While that dwarfs Goodyear’s current, 75-meter
Wingfoot One, it’s still only half the length of the Hindenburg. LTA expects Pathfinder 1 to carry approximately 4 tonnes of cargo, in addition to its crew, water ballast, and fuel. The airship will have a top speed of 65 knots, or about 120 kilometers per hour—on par with the Hindenburg—with a sustained cruise speed of 35 to 40 knots (65 to 75 km/h).
Some 21st-century Airship Tech
It may not seem much of an advance to be building an airship that flies no faster than the Hindenburg. But Pathfinder 1 carries a lot of new tech that LTA is betting will prove key to an airship resurgence.
For one, airships used to be constructed around riveted aluminum girders, which provided the highest strength-to-weight ratio available at the time. Instead, LTA will be using carbon-fiber tubes attached to titanium hubs. As a result, Pathfinder 1’s primary structure will be both stronger and lighter.
Pathfinder 1’s outer covering is also a step up from past generations. Airships like the 1930s’
Graf Zeppelin had coverings made out of doped cotton canvas. The dope painted on the fabric increased its strength and resiliency. But canvas is still canvas. LTA has instead built its outer coverings out of a three-layer laminate of synthetics. The outermost layer is DuPont’s Tedlar, which is a polyvinyl fluoride. The middle layer is a loose weave of fire-retardant aramid fibers. The inner layer is polyester. “It’s very similar to what’s used in a lot of racing sailboats,” says Taussig. “We needed to modify that material to make it fire resistant and change a little bit about its structural performance.”
But neither the materials science nor the manufacturing advances will take primary credit for LTA’s looked-for success, according to Taussig—instead, it’s the introduction of electronics. “Everything’s electric on Pathfinder,” he says. “All the actuation, all the propulsion, all the actual power is all electrically generated. It’s a fully electric fly-by-wire aircraft, which is not something that was possible 80 years ago.” Pathfinder 1 has 12 electric motors for propulsion, as well as four tail fins with steering rudders controlled by its fly-by-wire system. (During initial test flights, the airship will be powered by two reciprocating aircraft engines).
There’s one other piece of equipment making an appearance on Pathfinder 1 that wasn’t available 80 years ago:
lidar. Installed at the top of each of Pathfinder 1’s helium gas cells is an automotive-grade lidar. “The lidar can give us a point cloud showing the entire internal hull of that gas cell,” says Taussig, which can then be used to determine the gas cell’s volume accurately. In flight, the airship’s pilots can use that information, as well as data about the helium’s purity, pressure, and temperature, to better keep the craft pitched properly and to avoid extra stress on the internal structure during flight.
Although LTA’s initial focus is on humanitarian applications, there are other areas where airships might shine one day. “An airship is kind of a ‘tweener,’ in between sea cargo and air freight,” says Taussig. Being fully electric, Pathfinder 1 is also greener than traditional air- or sea-freight options.
After completing Pathfinder 1’s construction late in 2022, LTA plans to conduct a series of ground tests on each of the airship’s systems in the first part of 2023. Once the team is satisfied with those tests, they’ll move to tethered flight tests and finally untethered flight tests over San Francisco’s South Bay later in the year.
The company will also construct an approximately 180-meter-long airship,
Pathfinder 3 at its Akron Airdock facility in Ohio. Pathfinder 3 won’t be ready to fly in 2023, but its development shows LTA’s aspirations for an airship renaissance is more than just hot air.

Elon Musk, step aside. You may be the richest rich man in the space business, but you’re not first. Musk’s SpaceX corporation is a powerful force, with its weekly launches and visions of colonizing Mars. But if you want a broader view of how wealthy entrepreneurs have shaped space exploration, you might want to look at George Ellery Hale, James Lick, William McDonald or—remember this name—John D. Hooker.
All this comes up now because SpaceX, joining forces with the billionaire
Jared Isaacman, has made what sounds at first like a novel proposal to NASA: It would like to see if one of the company’s Dragon spacecraft can be sent to service the fabled, invaluable (and aging) Hubble Space Telescope, last repaired in 2009.
Private companies going to the rescue of one of NASA’s crown jewels? NASA’s mantra in recent years has been to let
private enterprise handle the day-to-day of space operations—communications satellites, getting astronauts to the space station, and so forth—while pure science, the stuff that makes history but not necessarily money, remains the province of government. Might that model change?
“We’re working on crazy ideas all the time,” said
Thomas Zurbuchen, NASA’s space science chief. "Frankly, that’s what we’re supposed to do.”
It’s only a six-month feasibility study for now; no money will change hands between business and NASA. But Isaacman, who made his fortune in
payment-management software before turning to space, suggested that if a Hubble mission happens, it may lead to other things. “Alongside NASA, exploration is one of many objectives for the commercial space industry,” he said on a media teleconference. “And probably one of the greatest exploration assets of all time is the Hubble Space Telescope.”
So it’s possible that at some point in the future, there may be a SpaceX Dragon, perhaps with Isaacman as a crew member, setting out to grapple the Hubble, boost it into a higher orbit, maybe even replace some worn-out components to lengthen its life.
Aerospace companies say privately mounted repair sounds like a good idea. So good that they’ve proposed it already.
The Chandra X-ray telescope, as photographed by space-shuttle astronauts after they deployed it in July 1999. It is attached to a booster that moved it into an orbit 10,000 by 100,000 kilometers from Earth.NASA
Northrop Grumman, one of the United States’ largest aerospace contractors, has quietly suggested to NASA that it might service one of the Hubble’s sister telescopes, the Chandra X-ray Observatory. Chandra was launched into Earth orbit by the space shuttle Columbia in 1999 (Hubble was launched from the shuttle Discovery in 1990), and the two often complement each other, observing the same celestial phenomena at different wavelengths.
As in the case of the SpaceX/Hubble proposal, Northrop Grumman’s Chandra study is at an early stage. But there are a few major differences. For one, Chandra was assembled by TRW, a company that has since been bought by Northrop Grumman. And another company subsidiary,
SpaceLogistics, has been sending what it calls Mission Extension Vehicles (MEVs) to service aging Intelsat communications satellites since 2020. Two of these robotic craft have launched so far. The MEVs act like space tugs, docking with their target satellites to provide them with attitude control and propulsion if their own systems are failing or running out of fuel. SpaceLogistics says it is developing a next-generation rescue craft, which it calls a Mission Robotic Vehicle, equipped with an articulated arm to add, relocate, or possibly repair components on orbit.
“We want to see if we can apply this to space-science missions,” says
Jon Arenberg, Northrop Grumman’s chief mission architect for science and robotic exploration, who worked on Chandra and, later, the James Webb Space Telescope. He says a major issue for servicing is the exacting specifications needed for NASA’s major observatories; Chandra, for example, records the extremely short wavelengths of X-ray radiation (0.01–10 nanometers).
“We need to preserve the scientific integrity of the spacecraft,” he says. “That’s an absolute.”
But so far, the company says, a mission seems possible. NASA managers have listened receptively. And Northrop Grumman says a servicing mission could be flown for a fraction of the cost of a new telescope.
New telescopes need not be government projects. In fact, NASA’s chief economist,
Alexander MacDonald, argues that almost all of America’s greatest observatories were privately funded until Cold War politics made government the major player in space exploration. That’s why this story began with names from the 19th and 20th centuries—Hale, Lick, and McDonald—to which we should add Charles Yerkes and, more recently, William Keck. These were arguably the Elon Musks of their times—entrepreneurs who made millions in oil, iron, or real estate before funding the United States’ largest telescopes. (Hale’s father manufactured elevators—highly profitable in the rebuilding after the Great Chicago Fire of 1871.) The most ambitious observatories, MacDonald calculated for his book The Long Space Age, were about as expensive back then as some of NASA’s modern planetary probes. None of them had very much to do with government.
To be sure, government will remain a major player in space for a long time. “NASA pays the cost, predominantly, of the development of new commercial crew vehicles, SpaceX’s Dragon being one,” MacDonald says. “And now that those capabilities exist, private individuals can also pay to utilize those capabilities.” Isaacman doesn’t have to build a spacecraft; he can hire one that SpaceX originally built for NASA.
“I think that creates a much more diverse and potentially interesting space-exploration future than we have been considering for some time,” MacDonald says.
So put these pieces together: Private enterprise has been a driver of space science since the 1800s. Private companies are already conducting on-orbit satellite rescues. NASA hasn’t said no to the idea of private missions to service its orbiting observatories.
And why does John D. Hooker’s name matter? In 1906, he agreed to put up US $45,000 (about $1.4 million today) to make the mirror for a
100-inch reflecting telescope at Mount Wilson, Calif. One astronomer made the Hooker Telescope famous by using it to determine that the universe, full of galaxies, was expanding.
The astronomer’s name was
Edwin Hubble. We’ve come full circle.

Direct Comparisons: Ahrefs vs SEMrush
Now that you know a little more about each tool, let's take a look at how they compare. I'll analyze each tool to see how they differ in interfaces, keyword research resources, rank tracking, and competitor analysis.
Ahrefs and SEMrush both offer comprehensive information and quick metrics regarding your website's SEO performance. However, Ahrefs takes a bit more of a hands-on approach to getting your account fully set up, whereas SEMrush's simpler dashboard can give you access to the data you need quickly.
In this section, we provide a brief overview of the elements found on each dashboard and highlight the ease with which you can complete tasks.
The Ahrefs dashboard is less cluttered than that of SEMrush, and its primary menu is at the very top of the page, with a search bar designed only for entering URLs.
Additional features of the Ahrefs platform include:
You can see analytics from the dashboard, including search engine rankings to domain ratings, referring domains, and backlink
Jumping from one tool to another is easy. You can use the Keyword Explorer to find a keyword to target and then directly track your ranking with one click.
The website offers a tooltip helper tool that allows you to hover your mouse over something that isn't clear and get an in-depth explanation.
When you log into the SEMrush Tool, you will find four main modules. These include information about your domains, organic keyword analysis, ad keyword, and site traffic.
You'll also find some other options like

Both Ahrefs and SEMrush have user-friendly dashboards, but Ahrefs is less cluttered and easier to navigate. On the other hand, SEMrush offers dozens of extra tools, including access to customer support resources.
When deciding on which dashboard to use, consider what you value in the user interface, and test out both.
If you're looking to track your website's search engine ranking, rank tracking features can help. You can also use them to monitor your competitors.
Let's take a look at Ahrefs vs. SEMrush to see which tool does a better job.
The Ahrefs Rank Tracker is simpler to use. Just type in the domain name and keywords you want to analyze, and it spits out a report showing you the search engine results page (SERP) ranking for each keyword you enter.
Rank Tracker looks at the ranking performance of keywords and compares them with the top rankings for those keywords. Ahrefs also offers:
You'll see metrics that help you understand your visibility, traffic, average position, and keyword difficulty.
It gives you an idea of whether a keyword would be profitable to target or not.
SEMRush offers a tool called Position Tracking. This tool is a project tool—you must set it up as a new project. Below are a few of the most popular features of the SEMrush Position Tracking tool:

The platform provides opportunities to track several SERP features, including Local tracking.
Intuitive reports allow you to track statistics for the pages on your website, as well as the keywords used in those pages.
Identify pages that may be competing with each other using the Cannibalization report.
Ahrefs is a more user-friendly option. It takes seconds to enter a domain name and keywords. From there, you can quickly decide whether to proceed with that keyword or figure out how to rank better for other keywords.
SEMrush allows you to check your mobile rankings and ranking updates daily, which is something Ahrefs does not offer. SEMrush also offers social media rankings, a tool you won't find within the Ahrefs platform. Both are good which one do you like let me know in the comment.
Keyword research is closely related to rank tracking, but it's used for deciding which keywords you plan on using for future content rather than those you use now.
When it comes to SEO, keyword research is the most important thing to consider when comparing the two platforms.
The Ahrefs Keyword Explorer provides you with thousands of keyword ideas and filters search results based on the chosen search engine.
Ahrefs supports several features, including:
It can search multiple keywords in a single search and analyze them together. At SEMrush, you also have this feature in Keyword Overview.

Quantum computing is a devilishly complex technology, with many technical hurdles impacting its development. Of these challenges two critical issues stand out: miniaturization and qubit quality.
IBM has adopted the superconducting qubit road map of reaching a 1,121-qubit processor by 2023, leading to the expectation that 1,000 qubits with today’s qubit form factor is feasible. However, current approaches will require very large chips (50 millimeters on a side, or larger) at the scale of small wafers, or the use of chiplets on multichip modules. While this approach will work, the aim is to attain a better path toward scalability.
Now researchers at MIT have been able to both reduce the size of the qubits and done so in a way that reduces the interference that occurs between neighboring qubits. The MIT researchers have increased the number of superconducting qubits that can be added onto a device by a factor of 100.
“We are addressing both qubit miniaturization and quality,” said William Oliver, the director for the Center for Quantum Engineering at MIT. “Unlike conventional transistor scaling, where only the number really matters, for qubits, large numbers are not sufficient, they must also be high-performance. Sacrificing performance for qubit number is not a useful trade in quantum computing. They must go hand in hand.”
The key to this big increase in qubit density and reduction of interference comes down to the use of two-dimensional materials, in particular the 2D insulator hexagonal boron nitride (hBN). The MIT researchers demonstrated that a few atomic monolayers of hBN can be stacked to form the insulator in the capacitors of a superconducting qubit.
Just like other capacitors, the capacitors in these superconducting circuits take the form of a sandwich in which an insulator material is sandwiched between two metal plates. The big difference for these capacitors is that the superconducting circuits can operate only at extremely low temperatures—less than 0.02 degrees above absolute zero (-273.15 °C).
Superconducting qubits are measured at temperatures as low as 20 millikelvin in a dilution refrigerator.Nathan Fiske/MIT
In that environment, insulating materials that are available for the job, such as PE-CVD silicon oxide or silicon nitride, have quite a few defects that are too lossy for quantum computing applications. To get around these material shortcomings, most superconducting circuits use what are called coplanar capacitors. In these capacitors, the plates are positioned laterally to one another, rather than on top of one another.
As a result, the intrinsic silicon substrate below the plates and to a smaller degree the vacuum above the plates serve as the capacitor dielectric. Intrinsic silicon is chemically pure and therefore has few defects, and the large size dilutes the electric field at the plate interfaces, all of which leads to a low-loss capacitor. The lateral size of each plate in this open-face design ends up being quite large (typically 100 by 100 micrometers) in order to achieve the required capacitance.
In an effort to move away from the large lateral configuration, the MIT researchers embarked on a search for an insulator that has very few defects and is compatible with superconducting capacitor plates.
“We chose to study hBN because it is the most widely used insulator in 2D material research due to its cleanliness and chemical inertness,” said colead author Joel Wang, a research scientist in the Engineering Quantum Systems group of the MIT Research Laboratory for Electronics.
On either side of the hBN, the MIT researchers used the 2D superconducting material, niobium diselenide. One of the trickiest aspects of fabricating the capacitors was working with the niobium diselenide, which oxidizes in seconds when exposed to air, according to Wang. This necessitates that the assembly of the capacitor occur in a glove box filled with argon gas.
While this would seemingly complicate the scaling up of the production of these capacitors, Wang doesn’t regard this as a limiting factor.
“What determines the quality factor of the capacitor are the two interfaces between the two materials,” said Wang. “Once the sandwich is made, the two interfaces are “sealed” and we don’t see any noticeable degradation over time when exposed to the atmosphere.”
This lack of degradation is because around 90 percent of the electric field is contained within the sandwich structure, so the oxidation of the outer surface of the niobium diselenide does not play a significant role anymore. This ultimately makes the capacitor footprint much smaller, and it accounts for the reduction in cross talk between the neighboring qubits.
“The main challenge for scaling up the fabrication will be the wafer-scale growth of hBN and 2D superconductors like [niobium diselenide], and how one can do wafer-scale stacking of these films,” added Wang.
Wang believes that this research has shown 2D hBN to be a good insulator candidate for superconducting qubits. He says that the groundwork the MIT team has done will serve as a road map for using other hybrid 2D materials to build superconducting circuits.

Email is the marketing tool that helps you create a seamless, connected, frictionless buyer journey. More importantly, email marketing allows you to build relationships with prospects, customers, and past customers. It's your chance to speak to them right in their inbox, at a time that suits them. Along with the right message, email can become one of your most powerful marketing channels.
2. What is benefits of email marketing?
Email marketing is best way for creating long term relationship with your clients, and increasing sales in our company.
Benefits of email marketing for bussiness:
Better brand recognition
Statistics of what works best
More traffic to your products/services/newsletter
Most bussinesses are using email marketing and making tons of money with email marketing.
3. What is the simplest day and time to send my marketing emails?
Again, the answer to this question varies from company to company. And again, testing is the way to find out what works best. Typically, weekends and mornings seem to be times when multiple emails are opened, but since your audience may have different habits, it's best to experiment and then use your data to decide.
4. Which metrics should I be looking at?
The two most important metrics for email marketing are open rate and click-through rate. If your emails aren't opened, subscribers will never see your full marketing message, and if they open them but don't click through to your site, your emails won't convert.
5. How do I write a decent subject line?
The best subject lines are short and to the point, accurately describing the content of the email, but also catchy and intriguing, so the reader wants to know more. Once Again, this is the perfect place for A/B testing, to see what types of subject lines work best with your audience. Your call to action should be clear and simple. It should be somewhere at the top of your email for those who haven't finished reading the entire email, then repeated at the end for those reading all the way through. It should state exactly what you want subscribers to do, for example "Click here to download the premium theme for free.
6. Is email marketing still effective?
Email marketing is one of the most effective ways for a business to reach its customers directly. Think about it. You don't post something on your site hoping people will visit it. You don't even post something on a social media page and hope fans see it. You're sending something straight to each person's inbox, where they'll definitely see it! Even if they don't open it, they'll still see your subject line and business name every time you send an email, so you're still communicating directly with your audience.
7. However do I grow my email subscribers list? Should i buy an email list or build it myself?
Buying an email list is waste of time & money. These email accounts are unverified and not interested in your brand. The mailing list is useless if your subscribers do not open your emails. There are different ways to grow your mailing list.
Give them a free ebook and host it on a landing page where they have to enter the email to download the file and also create a forum page on your website, asks your visitors what questions they might have about your business, and collects email addresses to follow up with them.
8. How do I prevent audience from unsubscribing?
If the subject line of the email is irrelevant to customers, they will ignore it multiple times. But, if it keeps repeating, they are intercepted and unsubscribed from your emails. So, send relevant emails for the benefit of the customer. Don't send emails that often only focus on sales, offers and discounts.
Submit information about your business and offers so you can connect with customers. You can also update them on recent trends in your industry. The basic role of an email is first and foremost to connect with customers, get the most out of this tool.
9. What is the difference between a cold email and a spam email?
Cold emails are mostly sales emails that are sent with content align to the needs of the recipient. It is usually personalized and includes a business perspective. However, it is still an unsolicited email. And all unsolicited emails are marked as SPAM.
Regularly receiving this type of unsolicited email in your users' inboxes, chances are your emails will soon be diverted to spam or junk folders. The most important thing to prevent this from happening is to respect your recipients' choice to opt-out of receiving emails from you. You can add the links to easily unsubscribe. You must be familiar with the CAN-SPAM Act and its regulations.
10. Where can I find email template?
Almost all email campaign tools provide you with ready-made templates. Whether you use MailChimp or Pardot, you'll get several email templates ready to use.
However, if you want to create a template from scratch, you can do so.Most of email campaign tools have option to paste the HTML code of your own design.
11. What email marketing trend will help marketers succeed in 2022?
Is it a trend to listen to and get to know your customers? I think people realize how bad it feels for a brand or a company to obsess over themselves without knowing their customers personal needs. People who listen empathetically and then provide value based on what they learn will win.
You can approach email marketing in different ways. We have compiled a list of most frequently asked questions to help you understand how to get started, what constraints you need to keep in mind, and what future development you will need, we don’t have 100% answers to every situation and there’s always a chance you will have something new and different to deal with as you market your own business.

From the time the ancient Sumerians started making sausage around 4,000 years ago, the process has been the province of artisans dedicated to the craft of preserving meat so it remained safe to eat for as long as possible. Yet even traditional methods can stand to be improved on from time to time. Katharina Koch of the Landfleischerei Koch in Calden, Germany [right], has retained ancient customs such as the clay chambers in which Ahle sausages ripen while also fine-tuning the conditions under which the meats are cured (such as temperature and moisture level) via AI algorithms. The digital modifications she and scientists at the nearby University of Kassel have developed replicate the production methods that have been passed down for generations. So, instead of spending nearly a year manually monitoring the meats’ maturation process, a sausage maker using the new AI methods will be able to set it and forget it.
People with diabetes will usually prick their fingers multiple times a day in order to get readings on the amount of glucose (the type of sugar the body uses for fuel) that is in their bloodstream. But researchers at the University of California, San Diego, have developed a bloodless method for tracking blood sugar and other chemical metabolites in the gastrointestinal tract that can be used to infer the person’s relative state of health. Their solution to the finger-pricking problem: an electronic pill capable of sensing metabolite levels and transmitting data wirelessly every 5 seconds over a span of several hours. So, instead of snapshots of how the body is reacting to stimuli like food, clinicians will get a steady stream of data. The major innovation boasted by the UCSD team is that their pill draws power from a fuel cell that runs on the glucose in the gut, instead of relying on a battery laden with potentially harmful chemicals.
The phrase musical arrangement has long referred to the work of art that results from a composition being adapted for different instruments or voices. But going forward, sound will get in on the act of arranging. Engineers at the Korea Advanced Institute of Science and Technology report that they used sound waves to disperse metallic droplets embedded in a polymer in order to make flexible circuits. This “musical arrangement” yields an archipelago of droplets spaced so that electrical conductivity is maintained even when the polymer is bent or twisted.

The relative proportions of a bee’s body and its wings say that, at least in theory, it shouldn’t be able to fly. But where would we be if bees were incapable of flitting from flower to flower, collecting nectar and spreading pollen? Roboticists at ETH Zurich, taking a page from nature, say they too have created a machine whose movement seems to defy the laws of physics. The 1.TK-meter-long gadget, called Cubli, balances on a single point, with a single internal reaction wheel whose spin keeps the unit upright. The way this is supposed to work, the Cubli would need a wheel to manage pitch and another to handle roll. But the Zurich team worked out the Cubli’s dimensions so the one wheel is capable of counterbalancing any forces that would topple the machine.

There’s a handful of robotics companies currently working on what could be called general-purpose humanoid robots. That is, human-size, human-shaped robots with legs for mobility and arms for manipulation that can (or, may one day be able to) perform useful tasks in environments designed primarily for humans. The value proposition is obvious—drop-in replacement of humans for dull, dirty, or dangerous tasks. This sounds a little ominous, but the fact is that people don’t want to be doing the jobs that these robots are intended to do in the short term, and there just aren’t enough people to do these jobs as it is.
We tend to look at claims of commercializable general-purpose humanoid robots with some skepticism, because humanoids are really, really hard. They’re still really hard in a research context, which is usually where things have to get easier before anyone starts thinking about commercialization. There are certainly companies out there doing some amazing work toward practical legged systems, but at this point, “practical” is more about not falling over than it is about performance or cost effectiveness. The overall approach toward solving humanoids in this way tends to be to build something complex and expensive that does what you want, with the goal of cost reduction over time to get it to a point where it’s affordable enough to be a practical solution to a real problem.
Apptronik, based in Austin, Texas, is the latest company to attempt to figure out how to make a practical general-purpose robot. Its approach is to focus on things like cost and reliability from the start, developing (for example) its own actuators from scratch in a way that it can be sure will be cost effective and supply-chain friendly. Apptronik’s goal is to develop a platform that costs well under US $100,000 of which it hopes to be able to deliver a million by 2030, although the plan is to demonstrate a prototype early this year. Based on what we’ve seen of commercial humanoid robots recently, this seems like a huge challenge. And in part two of this story (to be posted tomorrow), we will be talking in depth to Apptronik’s cofounders to learn more about how they’re going to make general-purpose humanoids happen.
But Apptronik has by no means abandoned its NASA roots. In 2019, NASA had plans for what was essentially going to be a Valkyrie 2, which was to be a ground-up redesign of the Valkyrie platform. As with many of the coolest NASA projects, the potential new humanoid didn’t survive budget prioritization for very long, but even at the time it wasn’t clear to us why NASA wanted to build its own humanoid rather than asking someone else to build one for it considering how much progress we’ve seen with humanoid robots over the last decade. Ultimately, NASA decided to move forward with more of a partnership model, which is where Apptronik fits in—a partnership between Apptronik and NASA will help accelerate commercialization of Apollo.
“We recognize that Apptronik is building a production robot that’s designed for terrestrial use,” says NASA’s Shaun Azimi, who leads the Dexterous Robotics Team at NASA’s Johnson Space Center. “From NASA’s perspective, what we’re aiming to do with this partnership is to encourage the development of technology and talent that will sustain us through the Artemis program and looking forward to Mars.”
Apptronik is positioning Apollo as a high-performance, easy-to-use, and versatile system. It is imagining an “iPhone of robots.”
“Apollo is the robot that we always wanted to build,” says Jeff Cardenas, Apptronik cofounder and CEO. This new humanoid is the culmination of an astonishing amount of R&D, all the way down to the actuator level. “As a company, we’ve built more than 30 unique electric actuators,” Cardenas explains. “You name it, we’ve tried it. Liquid cooling, cable driven, series elastic, parallel elastic, quasi-direct drive…. And we’ve now honed our approach and are applying it to commercial humanoids.”
Apptronik’s emphasis on commercialization gives it a much different perspective on robotics development than you get when focusing on pure research the way that NASA does. To build a commercial product rather than a handful of totally cool but extremely complex bespoke humanoids, you need to consider things like minimizing part count, maximizing maintainability and robustness, and keeping the overall cost manageable. “Our starting point was figuring out what the minimum viable humanoid robot looked like,” explains Apptronik CTO Nick Paine. “Iteration is then necessary to add complexity as needed to solve particular problems.”
This robot is called Astra. It’s only an upper body, and it’s Apptronik’s first product, but (not having any legs) it’s designed for manipulation rather than dynamic locomotion. Astra is force controlled, with series-elastic torque-controlled actuators, giving it the compliance necessary to work in dynamic environments (and particularly around humans). “Astra is pretty unique,” says Paine. “What we were trying to do with the system is to approach and achieve human-level capability in terms of manipulation workspace and payload. This robot taught us a lot about manipulation and actually doing useful work in the world, so that’s why it’s where we wanted to start.”
While Astra is currently out in the world doing pilot projects with clients (mostly in the logistics space), internally Apptronik has moved on to robots with legs. The following video, which Apptronik is sharing publicly for the first time, shows a robot that the company is calling its Quick Development Humanoid, or QDH:
QDH builds on Astra by adding legs, along with a few extra degrees of freedom in the upper body to help with mobility and balance while simplifying the upper body for more basic manipulation capability. It uses only three different types of actuators, and everything (from structure to actuators to electronics to software) has been designed and built by Apptronik. “With QDH, we’re approaching minimum viable product from a usefulness standpoint,” says Paine, “and this is really what’s driving our development, both in software and hardware.”
“What people have done in humanoid robotics is to basically take the same sort of architectures that have been used in industrial robotics and apply those to building what is in essence a multi-degree-of-freedom industrial robot,” adds Cardenas. “We’re thinking of new ways to build these systems, leveraging mass manufacturing techniques to allow us to develop a high-degree-of-freedom robot that’s as affordable as many industrial robots that are out there today.”
Cardenas explains that a major driver for the cost of humanoid robots is the number of different parts, the precision machining of some specific parts, and the resulting time and effort it then takes to put these robots together. As an internal-controls test bed, QDH has helped Apptronik to explore how it can switch to less complex parts and lower the total part count. The plan for Apollo is to not use any high-precision or proprietary components at all, which mitigates many supply-chain issues and will help Apptronik reach its target price point for the robot.
Apollo will be a completely new robot, based around the lessons Apptronik has learned from QDH. It’ll be average human size: about 1.75 meters tall, weighing around 75 kilograms, with the ability to lift 25 kg. It’s designed to operate untethered, either indoors or outdoors. Broadly, Apptronik is positioning Apollo as a high-performance, easy-to-use, and versatile robot that can do a bunch of different things. It is imagining an “iPhone of robots,” where apps can be created for the robot to perform specific tasks. To extend the iPhone metaphor, Apptronik itself will make sure that Apollo can do all of the basics (such as locomotion and manipulation) so that it has fundamental value, but the company sees versatility as the way to get to large-scale deployments and the cost savings that come with them.
“I see the Apollo robot as a spiritual successor to Valkyrie. It’s not Valkyrie 2—Apollo is its own platform, but we’re working with Apptronik to adapt it as much as we can to space use cases.” —Shaun Azimi, NASA Johnson Space Center
The challenge with this app approach is that there’s a critical mass that’s required to get it to work—after all, the primary motivation to develop an iPhone app is that there are a bajillion iPhones out there already. Apptronik is hoping that there are enough basic manipulation tasks in the supply-chain space that Apollo can leverage to scale to that critical-mass point. “This is a huge opportunity where the tasks that you need a robot to do are pretty straightforward,” Cardenas tells us. “Picking single items, moving things with two hands, and other manipulation tasks where industrial automation only gets you to a certain point. These companies have a huge labor challenge—they’re missing labor across every part of their business.”
While Apptronik’s goal is for Apollo to be autonomous, in the short to medium term, its approach will be hybrid autonomy, with a human overseeing first a few and eventually a lot of Apollos with the ability to step in and provide direct guidance through teleoperation when necessary. “That’s really where there’s a lot of business opportunity,” says Paine. Cardenas agrees. “I came into this thinking that we’d need to make Rosie the robot before we could have a successful commercial product. But I think the bar is much lower than that. There are fairly simple tasks that we can enter the market with, and then as we mature our controls and software, we can graduate to more complicated tasks.”
Apptronik is still keeping details about Apollo’s design under wraps, for now. We were shown renderings of the robot, but Apptronik is understandably hesitant to make those public, since the design of the robot may change. It does have a firm date for unveiling Apollo for the first time: SXSW, which takes place in Austin in March.

In parts of the United States, using the term “systemic racism” to refer to persistent discrimination against Black people has become a political flash point. To some ears, it sounds like an attack on the country and the local community. Several states have enacted laws that ban, or would appear to ban, discussing the concept in public schools and colleges, and even private workplaces. But racial-equity consultant Tynesia Boyea-Robinson uses the term with an engineer’s precision. When she first heard the phrase, she recalled her training in quality control in the transportation unit of GE Research, in Erie, Pa. And, sure enough, a lightbulb went on in her head: The system could be reengineered. “Oh my God, we can fix this!” she thought. “I don’t think everybody else sees it that way.”
Boyea-Robinson helps companies, government agencies, and other organizations meet goals for diversity and equity through her consulting firm, CapEQ. In October, her second book on this work, The Social Impact Advantage, was published. And she is the steward of Path to 15/55, an ambitious effort to deliver desperately needed capital to Black businesses across the United States. Since 2018, Boyea-Robinson has been assembling a coalition—including financial institutions, grassroots community groups, political and policy leaders, and corporate and philanthropic donors—to reprogram the systems of lending to and investing in these businesses.

Boyea-Robinson helps companies, government agencies, and other organizations meet goals for diversity and equity through her consulting firm, CapEQ. In October, her second book on this work, The Social Impact Advantage, was published. And she is the steward of Path to 15/55, an ambitious effort to deliver desperately needed capital to Black businesses across the United States. Since 2018, Boyea-Robinson has been assembling a coalition—including financial institutions, grassroots community groups, political and policy leaders, and corporate and philanthropic donors—to reprogram the systems of lending to and investing in these businesses.
Boyea-Robinson grew up in Cocoa Beach, Fla., where her father fixed satellites for the U.S. Air Force and her stepmother gave manicures in the family’s living room. In other circumstances, the straight As Boyea-Robinson earned at school and the lessons in mechanics her dad taught her might have ensured a trajectory toward a top STEM university. But her parents hadn’t gone to college and didn’t push her in that direction. Moreover, as the oldest, she was expected to help care for her four younger siblings. She expected to enroll at a community college until one of her stepmother’s clients pushed her to set her sights higher.
She attended Duke University’s Pratt School of Engineering, in Durham, N.C., where she earned a dual bachelor’s degree in electrical engineering and computer science. The curriculum was daunting, and she had to confront a persistent sense of being an outsider. But it was more than just the academics.
“There’s so many things about the culture of college that my parents couldn’t teach me,” she says. Adding to her initial anxiety was her status as one of the relatively few women at the engineering school—women made up just a quarter of the student body at Pratt—and there were even fewer Black students enrolled there (around 5 percent).
But when Boyea-Robinson graduated in 1999, she landed a plum information-management job at General Electric through the company’s prestigious leadership program. Though her anxiety about fitting in lingered, her career flourished. In 2003, she headed to Harvard Business School for an MBA that could give her upward trajectory an extra boost. Then her course changed when she took an internship at a nonprofit called Year Up. The organization helps prepare young adults, mostly poorer people of color, for entry-level IT jobs at large companies—jobs that recalled her first assignments at GE. “That student was me,” she says, “with different options and choices.”
Her assignment was to map out an expansion of Year Up from Boston to either Washington, D.C., or New York City. Boyea-Robinson pitched both. When she graduated in 2005, the nonprofit hired her to open the Washington location. She launched the first class in January 2006, and as she built Year Up’s presence in Washington, Boyea-Robinson’s work became a model for the organization nationwide, starting in New York later that year. Today, the nonprofit serves 16 metro areas and operates virtually in five others.
At Year Up, Boyea-Robinson began to hear about systemic racism, the biases that people collectively inject, consciously or not, into so many of the institutions and the rules governing society, leading to the disparate treatment of different groups of people. The knock-on effects from that discrimination exacerbate inequality—which then reinforces those biases in a sort of feedback loop. Thinking about all this, Boyea-Robinson concluded that she wanted to use systems engineering to tackle the problems of systemic racism on a larger scale.
Since launching CapEQ in 2011, Boyea-Robinson has worked with more than 50 clients, helping businesses such as Marriott and Nordstrom address their diversity and equity shortcomings. She has also worked with nonprofits and others seeking broader change, including those collaborating on Path to 15/55.
Path to 15/55 takes its premise from recent research by one of those organizations, the Association for Enterprise Opportunity, a trade group of nonprofits that make small loans to underserved entrepreneurs. The group found that if 15 percent of existing Black businesses could finance a single new employee, it would create US $55 billion in new economic activity. But Black entrepreneurs have been hobbled by the effects of an especially pernicious example of systemic racism. Until the 1960s, federal government policies explicitly prohibited Black people from buying homes in white neighborhoods and simultaneously decimated the value of Black neighborhoods. The result has been to deny most Black families the opportunity to build generational wealth on par with their white counterparts. Even today, Blacks are less likely to seek, or obtain, a home mortgage. Most small businesses are financed by savings or loans conditioned on good credit scores and a home that serves as collateral.
The coalition Boyea-Robinson assembled is pressing for systemic change on several levels. It’s pushing bankers and the financial industry at large to confront their own biases in lending. It also disseminates novel strategies for financing Black businesses to avoid the barriers that Black borrowers face, such as the use of credit scores to assess creditworthiness. The group will then rigorously collect data on which strategies work and which don’t to propagate what’s successful. Separately, it’s agitating for government policy changes to allow these new strategies to flourish.
Boyea-Robinson manages Path to 15/55 as if she were testing software with a feedback loop of its own. It starts with building awareness around a specific issue and forging alliances, or alignments, with like-minded organizations, which then go to work as communities of action to implement change.
“Everything we learn from communities of action becomes the information that we raise awareness on,” she says. “And the loop starts again: awareness, alignment, action. These are all unit tests that become systems tests.”
Boyea-Robinson still finds resistance to financing equity among bank loan officers. “The way racism shows up in lending is bankers saying that this work is not investable,” she says. “Shifting the narrative is why we spend so much time sharing reports and stories.”
Backed with a $250,000 grant from the Walmart Foundation, Path to 15/55 launched its first Community of Action in January. Piggybacking on work led by the Beneficial State Foundation, Boyea-Robinson has recruited five financial institutions to experiment with innovative ways to underwrite loans, and to build durable support within their organizations for the work—which, Boyea-Robinson says, is the only way these changes will stick. These institutions are expected to begin lending money by midyear. To lessen the risk of losses, Path to 15/55 will make the $1 million it has raised so far available for these loans.
And she’s joining forces with business accelerators to launch a second community of action, aimed at helping Black entrepreneurs buy existing businesses in corporate supply chains, later this year.
“Being able to kind of turbocharge work that is already compelling,” she says, “has been pretty exciting.”

In the latest push for nuclear power in space, the Pentagon’s Defense Innovation Unit (DIU) awarded a contract in May to Seattle-based Ultra Safe Nuclear to advance its nuclear power and propulsion concepts. The company is making a soccer ball–size radioisotope battery it calls EmberCore. The DIU’s goal is to launch the technology into space for demonstration in 2027.
Ultra Safe Nuclear’s system is intended to be lightweight, scalable, and usable as both a propulsion source and a power source. It will be specifically designed to give small-to-medium-size military spacecraft the ability to maneuver nimbly in the space between Earth orbit and the moon. The DIU effort is part of the U.S. military’s recently announced plans to develop a surveillance network in cislunar space.
Besides speedy space maneuvers, the DIU wants to power sensors and communication systems without having to worry about solar panels pointing in the right direction or batteries having enough charge to work at night, says Adam Schilffarth, director of strategy at Ultra Safe Nuclear. “Right now, if you are trying to take radar imagery in Ukraine through cloudy skies,” he says, “current platforms can only take a very short image because they draw so much power.”
Radioisotope power sources are well suited for small, uncrewed spacecraft, adds Christopher Morrison, who is leading EmberCore’s development. Such sources rely on the radioactive decay of an element that produces energy, as opposed to nuclear fission, which involves splitting atomic nuclei in a controlled chain reaction to release energy. Heat produced by radioactive decay is converted into electricity using thermoelectric devices.
Radioisotopes have provided heat and electricity for spacecraft since 1961. The Curiosity and Perseverance rovers on Mars, and deep-space missions including Cassini, New Horizons, and Voyager all use radioisotope batteries that rely on the decay of plutonium-238, which is nonfissile—unlike plutonium-239, which is used in weapons and power reactors.
For EmberCore, Ultra Safe Nuclear has instead turned to medical isotopes such as cobalt-60 that are easier and cheaper to produce. The materials start out inert, and have to be charged with neutrons to become radioactive. The company encapsulates the material in a proprietary ceramic for safety.
Cobalt-60 has a half-life of five years (compared to plutonium-238’s 90 years), which is enough for the cislunar missions that the DOD and NASA are looking at, Morrison says. He says that EmberCore should be able to provide 10 times as much power as a plutonium-238 system, providing over 1 million kilowatt-hours of energy using just a few pounds of fuel. “This is a technology that is in many ways commercially viable and potentially more scalable than plutonium-238,” he says.
One downside of the medical isotopes is that they can produce high-energy X-rays in addition to heat. So Ultra Safe Nuclear wraps the fuel with a radiation-absorbing metal shield. But in the future, the EmberCore system could be designed for scientists to use the X-rays for experiments. “They buy this heater and get an X-ray source for free,” says Schilffarth. “We’ve talked with scientists who right now have to haul pieces of lunar or Martian regolith up to their sensor because the X-ray source is so weak. Now we’re talking about a spotlight that could shine down to do science from a distance.”
Ultra Safe Nuclear’s contract is one of two awarded by the DIU—which aims to speed up the deployment of commercial technology through military use—to develop nuclear power and propulsion for spacecraft. The other contract was awarded to Avalanche Energy, which is making a lunchbox-size fusion device it calls an Orbitron. The device will use electrostatic fields to trap high-speed ions in slowly changing orbits around a negatively charged cathode. Collisions between the ions can result in fusion reactions that produce energetic particles.
Both companies will use nuclear energy to power high-efficiency electric propulsion systems. Electric propulsion technologies such as ion thrusters, which use electromagnetic fields to accelerate ions and generate thrust, are more efficient than chemical rockets, which burn fuel. Solar panels typically power the ion thrusters that satellites use today to change their position and orientation. Schilffarth says that the higher power from EmberCore should give a greater velocity change of 10 kilometers per second in orbit than today’s electric propulsion systems.
Ultra Safe Nuclear is also one of three companies developing nuclear fission thermal propulsion systems for NASA and the Department of Energy. Meanwhile, the Defense Advanced Research Projects Agency (DARPA) is seeking companies to develop a fission-based nuclear thermal rocket engine, with demonstrations expected in 2026.

Update 4 Nov. 2:45 p.m. EDT:Rocket Lab says its launch was successful, but booster recovery was not. It says it lost telemetry signals from the descending first stage during reentry.
“As standard procedure, we pull the helicopter from the recovery zone if this happens,” a company spokesperson said.
“If at first you don’t succeed….” Rocket Lab, the space launch company with two launchpads on the New Zealand coast, almost did succeed in May at something very difficult: To make its Electron booster reusable (and therefore far less expensive to fly), it tried catching the used first stage—in midair—with a helicopter as it descended by parachute toward the Pacific Ocean.
It came oh-so-close. On its first try, Rocket Lab’s helicopter successfully snagged the parachute with a hook at the end of a long cable—a remarkable piece of planning and flying. But the pilot, in the company’s words, “detected different load characteristics than previously experienced in testing,” and let the rocket fall in the water for a ship to recover it.
So try, try again. Rocket Lab is now making a new recovery attempt, this time with a rocket carrying an atmospheric-research satellite for the Swedish National Space Agency. If the helicopter can catch and hold onto the booster, it will fly it back to Rocket Lab’s production complex near Auckland for possible reuse.
“We’re eager to get the helicopter back out there,” said Peter Beck, Rocket Lab’s CEO and founder.
During Rocket Lab’s launch on 2 May 2022, the helicopter was able to catch the Electron rocket booster, but load issues forced the pilot to let the rocket fall to the water.Rocket Lab
“No changes since the May recovery,” said Morgan Bailey of Rocket Lab in an email to IEEE Spectrum, “but our team has carried out a number of capture rehearsals with test stages in preparation for this launch.”
Satellite operators are watching closely because, after Elon Musk’s SpaceX, Rocket Lab has established itself as a contender in space launches, especially for companies and government agencies with smaller payloads. This is its 32nd Electron launch since 2017. “They’ve become a major player,” said Chad Anderson of Space Capital, a venture capital firm.
Many of the world’s launch bases have historically been near the ocean for good reason: If rockets failed, open water is a relatively safe place for debris to fall. That’s why the United States uses coastal Florida and California, and the European Space Agency uses Kourou, French Guiana, on the northern coast of South America. Rocket Lab started in New Zealand and is expanding to the Virginia coast.
The downside is that saltwater and rocket hardware don’t mix very well; the water is corrosive, and cleanup is expensive. SpaceX goes to great lengths to land its boosters on barges or back at Cape Canaveral; Rocket Lab, whose boosters are smaller, can change its commercial space business dramatically if helicopter recoveries become routine.
The name of the mission for its first booster-recovery attempt was a playful “There and Back Again”; the second, suggested by an American space enthusiast, is “Catch Me if You Can.”
Here’s the plan: The Electron rocket, 18 meters tall, lifts off over the southern Pacific, aiming to place the satellite in a sun-synchronous orbit 585 kilometers high. The first stage, which made up 80 percent of the vehicle’s mass at launch, burns out after the first 70 km. Two minutes and 32 seconds into the flight, it drops off, following a long arc that, on past flights, would have sent it crashing into the ocean, about 280 km downrange.
This artist's conception envisions the helicopter, having successfully snagged the booster's parachute, carrying it back to dry land. A recovery ship is on standby. Rocket Lab
But Rocket Lab has equipped it with heat shielding, a guidance computer and control thrusters, protecting and steering it as it falls tailfirst at up to 8,300 kilometers per hour. Temperatures reach 2,400 °C as it’s slowed by the thickening air around it.
At an altitude of 13 km a small drogue parachute is deployed, followed by a main chute less than a minute later. They slow the booster’s descent to about 36 km/h.
The helicopter, a Sikorsky S-92, is waiting in the landing zone, trailing a grappling hook on a long cable. If all goes well, the helicopter flies over the descending rocket and snags the parachute cables about 2,000 meters above the ocean’s surface. Then it flies back to land with the rocket hanging underneath.
“The main advantage of air capture is that we’re not cleaning salt water out of it,” said Rocket Lab’s Bailey in an earlier interview. “We’re still in the test phase part of the program, and in terms of time and cost savings, that’ll be determined.”
But engines recovered from the ocean after previous launches have been refurbished and test-fired successfully, says Rocket Lab. Like many engineering efforts, it’s a step at a time.
“Being able to refly Electron without too much rework is the aim of the game,” says the company. “If we can achieve high level performance with engine parts recovered from the ocean, imagine what we can do with returned dry engines.”

6. Is it possible to promote affiliate offers on mobile devices?
Smartphones are essentially miniature computers, so publishers can display the same websites and offers that are available on a PC. But mobiles also offer specific tools not available on computers, and these can be used to good effect for publishers. Publishers can optimize their ads for mobile users by making them easy to access by this audience. Publishers can also make good use of text and instant messaging to promote their offers. As the mobile market is predicted to make up 80% of traffic in the future, publishers who do not promote on mobile devices are missing out on a big opportunity.

If you want to pay online, you need to register an account and provide credit card information. If you don't have a credit card, you can pay with bank transfer. With the rise of cryptocurrencies, these methods may become old.
Imagine a world in which you can do transactions and many other things without having to give your personal information. A world in which you don’t need to rely on banks or governments anymore. Sounds amazing, right? That’s exactly what blockchain technology allows us to do.
It’s like your computer’s hard drive. blockchain is a technology that lets you store data in digital blocks, which are connected together like links in a chain.
Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. They first proposed the system to ensure that timestamps could not be tampered with.
A few years later, in 1998, software developer Nick Szabo proposed using a similar kind of technology to secure a digital payments system he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first Blockchain and Bitcoin.
So, What is Blockchain?
A blockchain is a distributed database shared between the nodes of a computer network. It saves information in digital format. Many people first heard of blockchain technology when they started to look up information about bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure, decentralized records of transactions.
Blockchain allowed people to guarantee the fidelity and security of a record of data without the need for a third party to ensure accuracy.
To understand how a blockchain works, Consider these basic steps:
Blockchain collects information in “blocks”.
A block has a storage capacity, and once it's used up, it can be closed and linked to a previously served block.
Blocks form chains, which are called “Blockchains.”
More information will be added to the block with the most content until its capacity is full. The process repeats itself.
Each block in the chain has an exact timestamp and can't be changed.
Let’s get to know more about the blockchain.
How does blockchain work?
Blockchain records digital information and distributes it across the network without changing it. The information is distributed among many users and stored in an immutable, permanent ledger that can't be changed or destroyed. That's why blockchain is also called "Distributed Ledger Technology" or DLT.
Here’s how it works:
Someone or a computer will transacts
The transaction is transmitted throughout the network.
A network of computers can confirm the transaction.
When it is confirmed a transaction is added to a block
The blocks are linked together to create a history.
And that’s the beauty of it! The process may seem complicated, but it’s done in minutes with modern technology. And because technology is advancing rapidly, I expect things to move even more quickly than ever.
A new transaction is added to the system. It is then relayed to a network of computers located around the world. The computers then solve equations to ensure the authenticity of the transaction.
Once a transaction is confirmed, it is placed in a block after the confirmation. All of the blocks are chained together to create a permanent history of every transaction.
How are Blockchains used?
Even though blockchain is integral to cryptocurrency, it has other applications. For example, blockchain can be used for storing reliable data about transactions. Many people confuse blockchain with cryptocurrencies like bitcoin and ethereum.
Blockchain already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. For example, IBM's Food Trust uses blockchain to track food's journey before reaching its final destination.
Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases where dangerous allergens such as peanuts have accidentally been introduced into certain products.
Tracing and identifying the sources of an outbreak is a challenging task that can take months or years. Thanks to the Blockchain, however, companies now know exactly where their food has been—so they can trace its location and prevent future outbreaks.
Blockchain technology allows systems to react much faster in the event of a hazard. It also has many other uses in the modern world.
What is Blockchain Decentralization?
Blockchain technology is safe, even if it’s public. People can access the technology using an internet connection.
Have you ever been in a situation where you had all your data stored at one place and that one secure place got compromised? Wouldn't it be great if there was a way to prevent your data from leaking out even when the security of your storage systems is compromised?
Blockchain technology provides a way of avoiding this situation by using multiple computers at different locations to store information about transactions. If one computer experiences problems with a transaction, it will not affect the other nodes.
Instead, other nodes will use the correct information to cross-reference your incorrect node. This is called “Decentralization,” meaning all the information is stored in multiple places.
Blockchain guarantees your data's authenticity—not just its accuracy, but also its irreversibility. It can also be used to store data that are difficult to register, like legal contracts, state identifications, or a company's product inventory.
Pros and Cons of Blockchain
Blockchain has many advantages and disadvantages.
Accuracy is increased because there is no human involvement in the verification process.
One of the great things about decentralization is that it makes information harder to tamper with.
Safe, private, and easy transactions
Provides a banking alternative and safe storage of personal information
Data storage has limits.
The regulations are always changing, as they differ from place to place.
It has a risk of being used for illicit activities
Frequently Asked Questions About Blockchain
I’ll answer the most frequently asked questions about blockchain in this section.
Is Blockchain a cryptocurrency?
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It's a digital ledger that records every transaction seamlessly.
Is it possible for Blockchain to be hacked?
Yes, blockchain can be theoretically hacked, but it is a complicated task to be achieved. A network of users constantly reviews it, which makes hacking the blockchain difficult.
What is the most prominent blockchain company?
Coinbase Global is currently the biggest blockchain company in the world. The company runs a commendable infrastructure, services, and technology for the digital currency economy.
Who owns Blockchain?
Blockchain is a decentralized technology. It’s a chain of distributed ledgers connected with nodes. Each node can be any electronic device. Thus, one owns blockhain.
What is the difference between Bitcoin and Blockchain technology?
Bitcoin is a cryptocurrency, which is powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency
What is the difference between Blockchain and a Database?
Generally a database is a collection of data which can be stored and organized using a database management system. The people who have access to the database can view or edit the information stored there. The client-server network architecture is used to implement databases. whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, timestamp and transaction information. Modification of data is not allowed due to the design of the blockchain. The technology allows decentralized control and eliminates risks of data modification by other parties.
Blockchain has a wide spectrum of applications and, over the next 5-10 years, we will likely see it being integrated into all sorts of industries. From finance to healthcare, blockchain could revolutionize the way we store and share data. Although there is some hesitation to adopt blockchain systems right now, that won't be the case in 2022-2023 (and even less so in 2026). Once people become more comfortable with the technology and understand how it can work for them, owners, CEOs and entrepreneurs alike will be quick to leverage blockchain technology for their own gain.

Are you searching for an ecomerce platform to help you build an online store and sell products?
In this Sellfy review, we'll talk about how this eCommerce platform can let you sell digital products while keeping full control of your marketing.
And the best part? Starting your business can be done in just five minutes.
Let us then talk about the Sellfy platform and all the benefits it can bring to your business.
What is Sellfy?
Sellfy is an eCommerce solution that allows digital content creators, including writers, illustrators, designers, musicians, and filmmakers, to sell their products online. Sellfy provides a customizable storefront where users can display their digital products and embed "Buy Now" buttons on their website or blog. Sellfy product pages enable users to showcase their products from different angles with multiple images and previews from Soundcloud, Vimeo, and YouTube. Files of up to 2GB can be uploaded to Sellfy, and the company offers unlimited bandwidth and secure file storage. Users can also embed their entire store or individual project widgets in their site, with the ability to preview how widgets will appear before they are displayed.
Sellfy is a powerful e-commerce platform that helps you personalize your online storefront. You can add your logo, change colors, revise navigation, and edit the layout of your store. Sellfy also allows you to create a full shopping cart so customers can purchase multiple items. And Sellfy gives you the ability to set your language or let customers see a translated version of your store based on their location.
Sellfy gives you the option to host your store directly on its platform, add a custom domain to your store, and use it as an embedded storefront on your website. Sellfy also optimizes its store offerings for mobile devices, allowing for a seamless checkout experience.
Sellfy allows creators to host all their products and sell all of their digital products on one platform. Sellfy also does not place storage limits on your store but recommends that files be no larger than 5GB. Creators can sell both standard and subscription-based products in any file format that is supported by the online marketplace. Customers can purchase products instantly after making a purchase – there is no waiting period.
You can organize your store by creating your product categories, sorting by any characteristic you choose. Your title, description, and the image will be included on each product page. In this way, customers can immediately evaluate all of your products. You can offer different pricing options for all of your products, including "pay what you want," in which the price is entirely up to the customer. This option allows you to give customers control over the cost of individual items (without a minimum price) or to set pricing minimums—a good option if you're in a competitive market or when you have higher-end products. You can also offer set prices per product as well as free products to help build your store's popularity.
Sellfy is ideal for selling digital content, such as ebooks. But it does not allow you to copyrighted material (that you don't have rights to distribute).
Sellfy offers several ways to share your store, enabling you to promote your business on different platforms. Sellfy lets you integrate it with your existing website using "buy now" buttons, embed your entire storefront, or embed certain products so you can reach more people. Sellfy also enables you to connect with your Facebook page and YouTube channel, maximizing your visibility.
Payments and security
Sellfy is a simple online platform that allows customers to buy your products directly through your store. Sellfy has two payment processing options: PayPal and Stripe. You will receive instant payments with both of these processors, and your customer data is protected by Sellfy's secure (PCI-compliant) payment security measures. In addition to payment security, Sellfy provides anti-fraud tools to help protect your products including PDF stamping, unique download links, and limited download attempts.
Marketing and analytics tools
The Sellfy platform includes marketing and analytics tools to help you manage your online store. You can send email product updates and collect newsletter subscribers through the platform. With Sellfy, you can also offer discount codes and product upsells, as well as create and track Facebook and Twitter ads for your store. The software's analytics dashboard will help you track your best-performing products, generated revenue, traffic channels, top locations, and overall store performance.
To expand functionality and make your e-commerce store run more efficiently, Sellfy offers several integrations. Google Analytics and Webhooks, as well as integrations with Patreon and Facebook Live Chat, are just a few of the options available. Sellfy allows you to connect to Zapier, which gives you access to hundreds of third-party apps, including tools like Mailchimp, Trello, Salesforce, and more.
Sellfy has its benefits and downsides, but fortunately, the pros outweigh the cons.
It takes only a few minutes to set up an online store and begin selling products.
You can sell your products on a single storefront, even if you are selling multiple product types.
Sellfy supports selling a variety of product types, including physical items, digital goods, subscriptions, and print-on-demand products.
Sellfy offers a free plan for those who want to test out the features before committing to a paid plan.
You get paid the same day you make a sale. Sellfy doesn't delay your funds as some other payment processors do.
Print-on-demand services are available directly from your store, so you can sell merchandise to fans without setting up an integration.
You can conduct all store-related activities via the mobile app and all online stores have mobile responsive designs.
Everything you need to make your website is included, including a custom domain name hosting, security for your files, and the ability to customize your store
The file security features can help you protect your digital property by allowing you to put PDF stamps, set download limits, and SSL encryption.
Sellfy provides unlimited support.
Sellfy provides simple and intuitive tax and VAT configuration settings.
Marketing strategies include coupons, email marketing, upselling, tracking pixels, and cart abandonment.
Although the free plan is helpful, but it limits you to only 10 products.
Payment plans often require an upgrade if you exceed a certain sales amount per year.
The storefront designs are clean, but they're not unique templates for creating a completely different brand image.
Sellfy's branding is removed from your hosted product when you upgrade to the $49 per month Business plan.
The free plan does not allow for selling digital or subscription products.
In this article, we have taken a look at some of the biggest benefits associated with using sellfy for eCommerce. Once you compare these benefits to what you get with other platforms such as Shopify, you should find that it is worth your time to consider sellfy for your business. After reading this article all of your questions will be solved but if you have still some questions let me know in the comment section below, I will be happy to answer your questions.

But AI holds still more promise and potential for the semiconductor industry. To better understand how AI is set to revolutionize chip design, we spoke with Heather Gorr, senior product manager for MathWorks’ MATLAB platform.
How is AI currently being used to design the next generation of chips?
Heather Gorr: AI is such an important technology because it’s involved in most parts of the cycle, including the design and manufacturing process. There’s a lot of important applications here, even in the general process engineering where we want to optimize things. I think defect detection is a big one at all phases of the process, especially in manufacturing. But even thinking ahead in the design process, [AI now plays a significant role] when you’re designing the light and the sensors and all the different components. There’s a lot of anomaly detection and fault mitigation that you really want to consider.
Then, thinking about the logistical modeling that you see in any industry, there is always planned downtime that you want to mitigate; but you also end up having unplanned downtime. So, looking back at that historical data of when you’ve had those moments where maybe it took a bit longer than expected to manufacture something, you can take a look at all of that data and use AI to try to identify the proximate cause or to see something that might jump out even in the processing and design phases. We think of AI oftentimes as a predictive tool, or as a robot doing something, but a lot of times you get a lot of insight from the data through AI.
What are the benefits of using AI for chip design?
Gorr: Historically, we’ve seen a lot of physics-based modeling, which is a very intensive process. We want to do a reduced order model, where instead of solving such a computationally expensive and extensive model, we can do something a little cheaper. You could create a surrogate model, so to speak, of that physics-based model, use the data, and then do your parameter sweeps, your optimizations, your Monte Carlo simulations using the surrogate model. That takes a lot less time computationally than solving the physics-based equations directly. So, we’re seeing that benefit in many ways, including the efficiency and economy that are the results of iterating quickly on the experiments and the simulations that will really help in the design.
So it’s like having a digital twin in a sense?
Gorr: Exactly. That’s pretty much what people are doing, where you have the physical system model and the experimental data. Then, in conjunction, you have this other model that you could tweak and tune and try different parameters and experiments that let sweep through all of those different situations and come up with a better design in the end.
So, it’s going to be more efficient and, as you said, cheaper?
Gorr: Yeah, definitely. Especially in the experimentation and design phases, where you’re trying different things. That’s obviously going to yield dramatic cost savings if you’re actually manufacturing and producing [the chips]. You want to simulate, test, experiment as much as possible without making something using the actual process engineering.
We’ve talked about the benefits. How about the drawbacks?
Gorr: The [AI-based experimental models] tend to not be as accurate as physics-based models. Of course, that’s why you do many simulations and parameter sweeps. But that’s also the benefit of having that digital twin, where you can keep that in mind—it's not going to be as accurate as that precise model that we’ve developed over the years.
Both chip design and manufacturing are system intensive; you have to consider every little part. And that can be really challenging. It's a case where you might have models to predict something and different parts of it, but you still need to bring it all together.
One of the other things to think about too is that you need the data to build the models. You have to incorporate data from all sorts of different sensors and different sorts of teams, and so that heightens the challenge.
How can engineers use AI to better prepare and extract insights from hardware or sensor data?
Gorr: We always think about using AI to predict something or do some robot task, but you can use AI to come up with patterns and pick out things you might not have noticed before on your own. People will use AI when they have high-frequency data coming from many different sensors, and a lot of times it’s useful to explore the frequency domain and things like data synchronization or resampling. Those can be really challenging if you’re not sure where to start.
One of the things I would say is, use the tools that are available. There’s a vast community of people working on these things, and you can find lots of examples [of applications and techniques] on GitHub or MATLAB Central, where people have shared nice examples, even little apps they’ve created. I think many of us are buried in data and just not sure what to do with it, so definitely take advantage of what’s already out there in the community. You can explore and see what makes sense to you, and bring in that balance of domain knowledge and the insight you get from the tools and AI.
What should engineers and designers consider when using AI for chip design?
Gorr: Think through what problems you’re trying to solve or what insights you might hope to find, and try to be clear about that. Consider all of the different components, and document and test each of those different parts. Consider all of the people involved, and explain and hand off in a way that is sensible for the whole team.
How do you think AI will affect chip designers’ jobs?
Gorr: It’s going to free up a lot of human capital for more advanced tasks. We can use AI to reduce waste, to optimize the materials, to optimize the design, but then you still have that human involved whenever it comes to decision-making. I think it’s a great example of people and technology working hand in hand. It’s also an industry where all people involved—even on the manufacturing floor—need to have some level of understanding of what’s happening, so this is a great industry for advancing AI because of how we test things and how we think about them before we put them on the chip.
How do you envision the future of AI and chip design?
Gorr: It's very much dependent on that human element—involving people in the process and having that interpretable model. We can do many things with the mathematical minutiae of modeling, but it comes down to how people are using it, how everybody in the process is understanding and applying it. Communication and involvement of people of all skill levels in the process are going to be really important. We’re going to see less of those superprecise predictions and more transparency of information, sharing, and that digital twin—not only using AI but also using our human knowledge and all of the work that many people have done over the years.

A bomb explodes — medical devices set to action.
It is only in war that both sides of human ingenuity coexist so brutally. On the one side, it innovates to wound and kill, on the other it heals and saves lives. Side by side, but viscerally opposed.
Dr. Joe Fisher is devoted to the light side of human ingenuity, medicine. His research at Toronto’s University Health Network has made major breakthroughs in understanding the absorption and use of oxygen by the body. Then, based on the results, he developed new, highly efficient methods of delivering oxygen to patients.
In 2004, together with other physicians and engineers, he created a company to develop solutions based on his innovations. He named it after the Toronto neighborhood where he still lives — Thornhill Medical.
Meanwhile, the studies conducted by Dr. Fisher started drawing attention from the U.S. Marines. They had been looking for solutions to reduce the use of large, heavy, and potentially explosive oxygen tanks transported by their medical teams to military operation sites.
“At first, they asked us if we could prove that it was possible to ventilate patients using much less oxygen,” says Veso Tijanic, COO of Thornhill Medical. “We proved it. Then, they asked us whether we could develop a device for this. Finally, whether we could integrate other functionalities into this device.”
The device is currently saving lives in Ukraine, Thornhill Medical having donated a number of them as well as its mobile anesthesia delivery module MADM.
These back-and-forths lasted about five years, gradually combining science and technology. It resulted in a very first product, launched in 2011: MOVES, an innovative portable life support unit.
This cooperation has also deeply transformed Thornhill Medical.
“We used to see ourselves as an R&D laboratory, we have now also become a medical device manufacturer!” says Tijanic.
Whilst the U.S. Marines started using MOVES, Thornhill Medical continued to innovate. In 2017, it launched an enhanced version, MOVES SLC.
Today, the Canadian company employs a staff of about 70. It continues to do research and development with its own team and partners around the world, publishing regularly in scientific journals. It has sold MOVES SLC around the world and launched two other solutions, MADM and ClearMate.
MADM is a portable device (capable of functioning on extreme terrain) which connects to any ventilator to deliver gas anaesthesia. ClearMate is an instrument — also portable and without electricity — which allows to take quick action in case of carbon monoxide poisoning. This is the most common respiratory poisoning, where every second without treatment worsens consequences on the brain and other organs.
An innovative ventilator design
Just like these two products, the heart of MOVES SLC is a technology stemming directly from Dr. Fisher’s research in breathing sciences. It includes a ventilator operating in circle-circuit: It recovers the oxygen expired by the patient, carefully controls its concentration (high FiO2) and redistributes only the strict minimum to the patient.
MOVES SLC operates with significantly less oxygen than required by traditional open-circuit ventilators. This is so little that a small oxygen-concentrator — integrated into MOVES SLC, that extracts oxygen from ambient air — is sufficient. No need for supplies from large oxygen tanks.
Yet, MOVES SLC is more than an innovative ultra-efficient ventilator, says Tijanic: “It is a complete life support device.” In addition to its integrated oxygen concentrator, it also includes suction and several sensors that monitor vital signs and brings it all together via a unique interface that can be operated on the device or by a mobile touch screen.
The user can intubate a patient and monitor its ventilation (FiO2, ETCO2, SpO2, ABP and other indicators) in addition to the patient’s temperature (two sensors), blood pressure (internal and external) and 12-lead ECG. The evolution of these measurements can be followed over the last 24 hours.
All of this, in a device measuring only 84 cm x 14 cm x 25 cm, weighing about 21 kilograms (including interchangeable batteries) which can be slung across the shoulder.
“MOVES must function in the middle of military operations, and be resistant to vibrations, crashes and shock, continue operating smoothly in sandstorms or in the rain.” —Veso Tijanic, COO of Thornhill Medical
“MOVES SLC represents no more than 30 percent of the volume and weight of traditional equipment — ventilator, concentrator, suction, monitoring device,” adds the COO. Integrating various technologies in such a lightweight, compact package was, without surprise, a major challenge for the engineers. Still, not the most difficult one.
Making medical device components capable of withstanding extreme conditions will have been even more complex. “Traditional technologies were designed to function in hospitals,” explains Tijanic. “MOVES must function in the middle of military operations, and be resistant to vibrations, crashes and shock, continue operating smoothly in sandstorms or in the rain, in temperatures between -26°C and +54°C.”
Sometimes, the engineers could take existing components and develop protective features for them. Occasionally, they would recast them from different markets (oxygen sensors, for instance) to integrate them into their device. And in other cases, they had to start from scratch, creating their own robust components.
The challenge was successfully overcome: “MOVES is designed under the highest industry standards and has been tested and fully certified by various regulatory bodies.” It has been certified MIL-STD-810G, a ruggedness U.S. military standard, verified by over twenty different tests (acoustic vibration, explosive atmosphere, etc.).
The device is hence approved for use — not only transported, but actually used on a patient — in various helicopters, aircraft and land vehicles. And this makes a world of difference for Tijanic. “Critical care, such as we provide, normally requires specially equipped facilities or vehicles. With MOVES SLC, any place or vehicle — even civilian — of sufficient size, is an opportunity for treatment.”
Thornhill’s fully integrated mobile life support has been used by military medical teams for five years already. The device is currently saving lives in Ukraine, Thornhill Medical having donated a number of them as well as its mobile anesthesia delivery module MADM.
An Introduction to MOVES SLC
In July 2022, the U.S. Army published a report summarizing its medical modernization strategy. The 22-page report confirms the need for ever more lightweight, compact, and cost-effective technology. It also mentions the use of artificial intelligence for more autonomous monitoring of the patients’ medical condition. Thornhill is exploring the AI angle.
“There isn’t always a qualified expert available everywhere,” explains Tijanic. “AI could ensure the optimum settings of the device, and then modify these depending on how the patient’s condition evolves.”
Thornhill is also exploring another solution for cases where no experts are available on spot. Last April, a MOVES SLC was used in a demonstration of “remote control of ventilators and infusion pumps to support disaster care.” Operators based in Seattle successfully controlled remotely a device based in Toronto. Science-fiction thus becomes science, and turns into reality.
The Canadian company continues innovating to heal and save lives on rough chaotic terrain and in the most extreme and unpredictable circumstances. It is driven by medical and technological progress. It is also driven by a many-thousand-year-old trend: Humans will likely never stop waging war.

Over 80 million magnetic resonance imaging (MRI) scans are conducted worldwide every year. MRI systems come in many different shapes and sizes, and are identified by their magnetic field strength. These scanners can range from below 0.55 tesla (T) to 3 T and beyond, where tesla is the unit for the static magnetic field strength. For patients with implanted metallic medical devices, the strong magnetic fields generated by MRI systems can pose several safety concerns.
For instance, high-powered magnets generate forces and torques that can cause the implant to migrate and potentially harm the patient. In addition, the gradient coils in MRI systems, used for spatial localization, can cause gradient-induced heating, vibrations, stimulation of the tissue, and device malfunction. Lastly, the large radiofrequency (RF) coil in MRI systems can cause the electrically conductive implant to electromagnetically resonate (called the “antenna effect”), resulting in RF-induced heating that can potentially burn the patient (Ref. 1).
MED Institute, a full-service contract research organization (CRO) for the medical device industry, is using multiphysics simulation to better understand the effects of RF-induced heating of medically implanted devices for patients that need MRI scans (Ref. 2).
Standardized Test Methods for Medical Devices
MED Institute provides support throughout the entire product development cycle. Its MRI Safety team helps manufacturers evaluate and perform physical testing of their medical devices for safety and compliance in the MRI environment (Figure 1). The team works closely with the Food and Drug Administration (FDA), which oversees the development of medical products to ensure safe and effective use. Furthermore, the team complies with the standards of the American Society for Testing and Materials (ASTM) and International Organization for Standardization (ISO). Specifically, it follows the ASTM F2182 standard to measure RF-induced heating of a medical implant within a gel phantom (Figure 2) and follows ISO/TS 10974 to evaluate electrically active implantable medical devices (AIMD) during MRI.
The gel phantom used for testing is a rectangular acrylic container filled with a conductive gel that approximates the thermal and electrical properties of average human tissue (Ref. 3). The phantom is placed on the patient table inside the RF coil of an MRI scanner and fiber optic temperature probes (1 mm in diameter) are attached to the device before submerging it into the gel. The probes measure the temperature changes experienced by the device during the MRI scan. This type of physical experiment is used often, but it poses some potential problems. For instance, movement within the phantom can introduce uncertainty into the experiment, and inaccurate probe placement can lead to invalid results. In addition, depending on the materials of construction and their magnetic susceptibility, magnetic force could also be an issue (Ref. 4).
To help address these issues, the team at MED Institute uses computational modeling and simulation as an alternative to physical testing. David Gross, PhD, PE, Director of MRI Safety Evaluations and Engineering Simulations, leads a team of analysts that use simulation to gain a better understanding of physics-based problems. He says, “The simulation provides us with 3D temperature contours anywhere within a volume of interest; we are not limited to discrete point-probe measurements, and we do not have to worry about the inaccuracies of the equipment or uncertainty of probe placement from the experiment.”
The team has experience conducting these simulations for closed-bore MRI systems, in which a patient is contained in a compact tube. The team is now using simulation to perform these same analyses for open-bore systems (Figure 3), which have wider physical access, making them beneficial for “imaging pediatric, bariatric, geriatric and claustrophobic patients”, as is explained on the MED Institute website (Ref. 5).
Multiphysics Simulation for RF-Induced Heating
With COMSOL Multiphysics, MED Institute is able to evaluate the RF-induced temperature rise of implants and compare the results of various sizes and constructs of a device within a product family to determine a worst-case configuration. The analysts at MED can import a CAD file of a client’s device using the CAD Import Module, an add-on to COMSOL Multiphysics. In terms of RF-induced heating, the team uses the RF Module and Heat Transfer Module add-on products to combine the physics of electromagnetics with transient heat transfer. For analyzing electromagnetics, the RF Module enables the use of Maxwell’s equations to solve for the wave equation at every point within the model that is impacted by electromagnetic fields. This is done in a steady-state frequency domain, which is then sequentially coupled to the transient heat transfer. With the Heat Transfer Module, the team is also able to solve heat conduction equations.
In the example below, MED Institute imported a CAD file of a knee implant into the COMSOL Multiphysics software. The geometry of the implant included a stem extension, tibial tray, femoral tray, and other components. All of these components can have various sizes and can be assembled in various ways, and patients with the implant can be scanned in various MRI systems that create different electromagnetic fields. With the overwhelming amount of permutations that these variables can produce, it is often not clear which configuration would result in the worst-case RF-induced heating.
“With our Medical Device Development Tool (MDDT), we can not only augment physical testing but even replace it with simulation in some cases. The immediate, positive results are that our clients are able to have their products evaluated quicker and at less cost because we are able to rely on the simulation.”
—David Gross, MED Institute Director of MRI Safety Evaluations and Engineering Simulations
“This is where the use of simulation comes in; you focus your efforts on the primary factors that can change the resonance of a particular implant,” Gross says. By using the COMSOL software, the organization is able to better understand the relative bounds of where it would expect to see resonance and how the device behaves under different electromagnetic fields. This helps with performing sensitivity analyses, where the team can test what causes the change in resonance, such as modifying the diameter of the stem or other components of the implant. For this particular case, the team ran hundreds of simulations to determine the worst-case device size and worst-case RF frequency.
Using worst-case analysis is crucial in the verification process because it allows manufacturers to test different factors for a wide range of devices — such as determining which size brings the most complications — rather than conducting physical testing for every variant of one product (Ref. 6). “Performing multiple physical experiments becomes very expensive and time-consuming, especially when you account for the hourly cost of using a physical MRI scanner,” says Gross.
As shown in Figure 4, the electric field in the gel phantom of a 1.2 T open-bore system (upper left) is very different from a 1.5 T closed-bore system (upper right). The knee implant was simulated in both systems, where the results show a different resonance and maximum temperature rise at the end of the stem (lower images).
Using COMSOL allowed the team to better understand how a device behaves under electromagnetic fields. With these results, the team was then able to determine where they should place temperature probes while physically testing the device in an actual MRI system to obtain temperature rise results.
FDA Qualification of MED Institute’s Virtual MRI Safety Evaluations
MED Institute’s experience with using simulation to test RF-induced heating of medical devices has inspired development of a promising new simulation tool that accelerates the product development cycle. The MED Institute team submitted this simulation tool to the FDA’s Medical Device Development Tool (MDDT) program, which allows the FDA to evaluate new tools with the purpose of furthering medical products and studies. As stated on the FDA website, “The MDDT program is a way for the FDA to qualify tools that medical device sponsors can choose to use in the development and evaluation of medical devices.” (Ref. 7) Once qualified, the FDA recognizes the tool as an official MDDT.
In November 2021, MED Institute was granted FDA qualification of its MDDT, “Virtual MRI Safety Evaluations of Medical Devices”. This is an evaluation process that involves using multiphysics modeling and simulation to test the interactions of medical devices in an MRI environment. The tool is used for modeling an RF coil of an MRI system, ASTM gel phantom, and a medical device placed within the gel. Simulation is then used to analyze the electromagnetics and the heat that generates around the device (Ref. 8).
After testing is complete, the labeling of the device is described by ASTM 2503 or, if it is an electrically active implant, by the ISO 10974 test. The labeling is placed on the device packaging and inside the instructions for use (IFU) so that an MRI technologist or radiologist can see the relevant information for a patient with an implanted device.
“With our MDDT, we can not only augment physical testing but even replace it with simulation in some cases,” says Gross.
Modeling and Simulation Support from the FDA
Over the years, MED Institute has evaluated many medical devices for MRI safety with COMSOL Multiphysics simulations. It has found that COMSOL is a powerful and efficient platform for solving complex multiphysics problems. “The immediate, positive results are that our clients are able to have their products evaluated quicker and at less cost because we are able to rely on the simulation. It does not require them to send us the actual product to test for RF-induced heating,” says Gross.
The FDA has been supportive of computational modeling and is willing to evaluate and accept data from simulation in lieu of physical testing. “It is important for medical device sponsors to know that they have the encouragement and support of the Agency,” Gross says. MED Institute has had the privilege of working alongside the FDA for many years for the benefit of patients. “It goes to show that they are invested and believe in the power of modeling and simulation,” Gross adds.
An experimental, potentially revolutionary all-electric airplane designed by NASA will soon be taking its first test flight, which will mark a major milestone for battery-powered aviation. However, the program already appears destined to fall short of its lofty goal to exploit the unique features of electric propulsion to rewrite the design rules for modern aircraft. Its time and funding has nearly run out.
Part of the agency’s storied X-plane program, the X-57 Maxwell set out with the ambitious goal of tackling two grand challenges in aerospace engineering simultaneously. Not only did it aim to show that an airplane could be powered entirely by electricity, it also planned to demonstrate the significant gains in efficiency and performance that could be made by switching from two large engines to many smaller ones evenly distributed across the wings—a configuration known as a “blown wing.”
The plan was to demonstrate both of these propositions through a series of increasingly advanced test vehicles. Ultimately though, the complexity of the first challenge, compounded by disruptions caused by the COVID-19 pandemic, saw timelines repeatedly pushed back. As a result, the project’s leaders say it no longer has the funding to progress to the latter stages of the program.
“It turned out to be actually a pretty tall order to work through all of those airworthiness, and qualification, and design challenges.” —Sean Clarke, NASA
The first iteration of the X-57, a modified Tecnam P2006T light aircraft whose gas-powered engines have been replaced with electric motors, will take flight this coming spring or possibly summer. (As of early January, NASA is still unclear as to precisely when that maiden voyage will be. NASA officials Spectrum contacted could only narrow the timeframe down to “first half of 2023.”) That will be a significant achievement, making the X-57 one of just a handful of electrically powered aircraft to get off the ground. But the team say they plan to wrap up flight testing by the end of the year and will no longer be building more advanced designs featuring novel wing configurations and distributed propulsion, such as the blown wing.
“We tried to do a very ambitious thing. Trying to do a new type of airframe and a new motor project is not very typical, because those are both very, very challenging endeavors,” says Nick Borer, deputy principal investigator for the X-57 project at the NASA Langley Research Center. “The agency funds a lot of different things and they’ve been very generous with what they’ve provided to us. But there are priorities at the top and eventually, you’ve got to finish up.”
The project’s ultimate goal was to take advantage of the benefits of electric propulsion to reimagine the design of aircraft wings. For instance, in the case of that blown wing: the large number of motors and props on the leading-edge force air at high rates over the wing, which can generate significant lift even at low speeds. This makes it possible to take off from shorter runways and can also allow you to shrink the size of the wing, reducing drag and boosting cruise efficiency.
The design is difficult to achieve with conventional combustion engines, because they are relatively heavy and become increasingly inefficient as they are scaled down in size. The same is not true of electric motors though, which means it’s relatively simple to switch from several large motors to many smaller ones distributed along the wing.
The current iteration of the X-57, pictured here, is powered by two electric motors and is based at the NASA Armstrong Flight Research Center in California.Carla Thomas/NASA
The final design iteration of the X-57 had six small electrically powered propellers across the front of each wing. The wings themselves would be only 40 percent of the size of a conventional P2006T wing. The design also featured two larger motors mounted on the tips of each wing, which would further reduce drag by counteracting the vortices normally produced at the end of each wing. Because the high lift generated by the smaller propellers along the leading edge would only be needed at take-off, these were designed to fold up once at cruising altitude to further reduce drag.
“The whole idea of an X-plane is to do something that has never been done before, and so I think it is just normal to expect that there is a learning curve.” —Sergio Cecutta, SMG Consulting
Altogether these aerodynamic innovations would slash the planes’ power consumption at cruise by as much as a third, according to Borer. Electric motors are also about three times more efficient in terms of their power-to-weight ratio compared to gasoline-burning ones, he adds, so combined these design changes were expected to lead to a roughly fivefold reduction in energy requirements while flying at cruise speeds of around 280 kilometers per hour.
Switching to electric propulsion turned out to be more complicated than envisioned. The team had to completely redesign their battery packs in 2017 to avoid the risk of catastrophic fires. The high voltages and power levels required for electric aviation also posed significant complications, says Borer, requiring several iterations of the systems designed to protect components from electromagnetic interference.
Early on in the project they also found that state-of-the-art transistors able to withstand high power levels couldn’t tolerate the vibrations and temperatures involved in flight. This was resolved only recently by switching to a newer generation of silicon carbide MOSFET modules, says Sean Clarke, principal investigator for the X-57 project at the NASA Armstrong Flight Research Center in California. “It turned out to be actually a pretty tall order to work through all of those airworthiness, and qualification, and design challenges,” he says.
This led to delays that will mean the more ambitious goals of the project may not come to fruition, but Borer hopes that others will be able to pick up from where they left off. The team has been regularly publishing their findings and data as they’ve progressed, he says. They are also actively contributing to standards for electric aviation and are working with regulators to help develop aircraft certification processes. “We’re pushing out everything that we can,” says Borer.

This information sharing has already borne fruit. NASA’s main subcontractor for the project California-based Empirical Systems Aerospace has been able to commercialize the X-57’s battery pack design, and the agency has a technology-transfer agreement with Virginia-based electric-aircraft designer Electra, which involved the team sharing information on their aerodynamic innovations. The company that NASA initially contracted to build their electric motors, Joby Aviation, has also gone on to develop their own electric vertical take-off and landing (eVTOL) vehicle and is today one of the leaders in the industry.
This is the beauty of a publicly funded effort like the X-57, says Sergio Cecutta, founder and partner at SMG Consulting, who covers the electric-aviation industry. Unlike a private development effort, he says, all of the advances and lessons that have come out of the project will be in the public domain and can spread throughout the industry. And while it may not have achieved its most ambitious goals, Cecutta says it has done exactly what was intended, which was to remove some of the roadblocks holding back electric aviation.

There is currently a lot of interest in AI tools designed to help programmers write software. GitHub’s Copilot and Amazon’s CodeWhisperer apply deep-learning techniques originally developed for generating natural-language text by adapting it to generate source code. The idea is that programmers can use these tools as a kind of auto-complete on steroids, using prompts to produce chunks of code that developers can integrate into their software.
Looking at these tools, I wondered: Could we take the next step and take the human programmer
out of the loop? Could a working program be written and deployed on demand with just the touch of a button?
In my day job, I write embedded software for microcontrollers, so I immediately thought of a self-contained handheld device as a demo platform. A screen and a few controls would allow the user to request and interact with simple AI-generated software. And so was born the idea of infinite
Pong for a number of reasons. The gameplay is simple, famously explained on Atari’s original 1972 Pong arcade cabinet in a triumph of succinctness: “Avoid missing ball for high score.” An up button and a down button is all that’s needed to play. As with many classic Atari games created in the 1970s and 1980s, Pong can be written in a relatively few lines of code, and has been implemented as a programming exercise many, many times. This means that the source-code repositories ingested as training data for the AI tools are rich in Pong examples, increasing the likelihood of getting viable results.
I used a US $6
Raspberry Pi Pico W as the core of my handheld device—its built-in wireless allows direct connectivity to cloud-based AI tools. To this I mounted a $9 Pico LCD 1.14 display module. Its 240 x 135 color pixels is ample for Pong, and the module integrates two buttons and a two-axis micro joystick.
My choice of programming language for the Pico was
MicroPython, because it is what I normally use and because it is an interpreted- language code that can be run without the need of a PC-based compiler. The AI coding tool I used was the OpenAI Codex. The OpenAI Codex can be accessed via an API that responds to queries using the Web’s HTTP format, which are straightforward to construct and send using the urequests and ujson libraries available for MicroPython. Using the OpenAI Codex API is free during the current beta period, but registration is required and queries are limited to 20 per minute—still more than enough to accommodate even the most fanatical Pong jockey.
Only two hardware modules are needed–a Rasperry Pi Pico W [bottom left] that supplies the compute power and a plug-in board with a screen and simple controls [top left]. Nothing else is needed except a USB cable to supply power.James Provost
The next step was to create a container program. This program is responsible for detecting when a new version of Pong is requested via a button push and when it, sends a prompt to the OpenAI Codex, receives the results, and launches the game. The container program also sets up a hardware abstraction layer, which handles the physical connection between the Pico and the LCD/control module.
The most critical element of the whole project was creating the prompt that is transmitted to the OpenAI Codex every time we want it to spit out a new version of
Pong. The prompt is a chunk of plain text with the barest skeleton of source code—a few lines outlining a structure common to many video games, namely a list of libraries we’d like to use, and a call to process events (such as keypresses), a call to update the game state based on those events, and a call to display the updated state on the screen.
The code that comes back produces a workable Pong game about 80 percent of the time.
How to use those libraries and fill out the calls is up to the AI. The key to turning this generic structure into a
Pong game are the embedded comments—optional in source code written by humans, really useful in prompts. The comments describe the gameplay in plain English—for example, “The game includes the following classes…Ball: This class represents the ball. It has a position, a velocity, and a debug attributes [sic]. Pong: This class represents the game itself. It has two paddles and a ball. It knows how to check when the game is over.” (My container and prompt code are available on Hackaday.io) (Go to Hackaday.io to play an infinite number of Pong games with the Raspberry Pi Pico W; my container and prompt code are on the site.)
What comes back from the AI is about 300 lines of code. In my early attempts the code would fail to display the game because the version of the MicroPython
framebuffer library that works with my module is different from the framebuffer libraries the OpenAI Codex was trained on. The solution was to add the descriptions of the methods my library uses as prompt comments, for example: “def rectangle(self, x, y, w, h, c).” Another issue was that many of the training examples used global variables, whereas my initial prompt defined variables as attributes scoped to live inside individual classes, which is generally a better practice. I eventually had to give up, go with the flow, and declare my variables as global.
The variations of Pong created by the OpenAI Codex vary widely in ball and paddle size and color and how scores are displayed. Sometimes the code results in an unplayable game, such as at the bottom right corner, where the player paddles have been placed on top of each other.James Provost
The code that comes back from my current prompt produces a workable
Pong game about 80 percent of the time. Sometimes the game doesn’t work at all, and sometimes it produces something that runs but isn’t quite Pong, such as when it allows the paddles to be moved left and right in addition to up and down. Sometimes it’s two human players, and other times you play against the machine. Since it is not specified in the prompt, Codex takes either of the two options. When you play against the machine, it’s always interesting to see how Codex has implemented that part of code logic.
So who is the author of this code? Certainly there are
legal disputes stemming from, for example, how this code should be licensed, as much of the training set is based on open-source software that imposes specific licensing conditions on code derived from it. But licenses and ownership are separate from authorship, and with regard to the latter I believe it belongs to the programmer who uses the AI tool and verifies the results, as would be the case if you created artwork with a painting program made by a company and used their brushes and filters.
As for my project, the next step is to look at more complex games. The 1986 arcade hit
Arkanoid on demand, anyone?

Almost 95 percent of the leaders said incorporating technologies that would help their organization become more sustainable and energy efficient was a top priority.
The executives said they thought telecommunications, transportation, energy, and financial services would be the areas most affected by technology this year.
They also shared what areas would benefit from 5G implementation.
The impact of 5G
Almost all of the tech leaders agreed that 5G is likely to impact vehicle connectivity and automation the most. They said areas that will benefit from 5G include remote learning and education; telemedicine; live streaming of sports and other entertainment programs; day-to-day communications; and transportation and traffic control.
About 95 percent said satellites that are used to provide connectivity in rural areas will enable devices with 5G to connect from anywhere at any time. In aninterview with IEEE Transmitter about the results, IEEE Senior Member Eleanor Watson predicted that the space satellites will be game-changers because they “enable leapfrogging off the need to build very expensive terrestrial infrastructure. They’re also the ultimate virtual private network—VPN—for extrajurisdictional content access.”
Automation through AI and digital twins
Nearly all the tech leaders—98 percent—said routine tasks and processes such as data analysis will be automated thanks to AI-powered autonomous collaborative software and mobile robots, allowing workers to be more efficient and effective.
The same percentage agreed that digital twin technology and virtual simulations that more efficiently design, develop, and test prototypes and manufacturing processes will become more important. A digital twin is a virtual model of a real-world object, machine, or system that can be used to assess how the real-world counterpart is performing.
Meetings in the metaverse
The leaders are considering ways to use the metaverse in their operations. Ninety-one percent said they plan to use the technology for corporate training sessions, conferences, and hybrid meetings. They said that 5G and ubiquitous connectivity, virtual reality headsets, and augmented reality glasses will be important for advancing the development of the metaverse.
Companies are looking to the metaverse to help them with their sustainable development goals. IEEE Senior Member Daozhuang Lin told IEEE Transmitter that “metaverse-related technology will be a major contributor to reducing carbon emissions because it allows technologists and engineers to perform simulations, rather than relying on real-world demonstrations that run on traditional energy.” But for the technology to really take off, the respondents said, more innovations are needed in 5G and ubiquitous connectivity, virtual-reality headsets, augmented-reality glasses, and haptic devices.

Optical fiber has long since replaced copper wiring in core information networks. But that’s not the case for free-space optical (FSO) communications using optical lasers to transmit data through the air. Despite FSO having the potential to provide orders of magnitude more data capacity compared with that of the traditional radio-frequency communications space missions currently rely on, the technology has been stuck on the launch pad because of atmospheric interference that can absorb and scatter the signals, as well as the strict acquisition and tracking requirements for communicating between ground stations and orbiting satellites.
“We’ve been able to maintain a robust single-mode fiber coupling resulting in an uninterrupted 100-gigabits-per-second optical-data link,” says Shane Walsh, team leader of the project. “We do this by tracking the drone at angular rates up to 1.5 degrees a second—the equivalent of tracking a satellite in low Earth orbit (LEO).”
With the greater data capacity of coherent communications and its compatibility with standard fiber optics, Walsh says the way is now open to developing terabits-per-second communications between LEO satellites and suitably equipped ground stations. “You can think of it as taking ground-to-space communications from dial-up speeds to superfast broadband speeds,” he adds.
“This multidisciplinary approach by the researchers and the test results are impressive,” says Alan Willner, a professor of electrical engineering specializing in optical communications at the University of Southern California. “They appear to have mitigated some of the key issues with free-space optical communications such as communicating through turbulence, and in pointing and tracking at speeds needed to communicate with low-orbiting satellites.”
Benjamin Dix-Matthews, who is researching the optics for the project, describes the setup used. A PlaneWave Instruments L-350 direct-drive mount is employed to enable tracking of the target. Attached to it is an optical breadboard housing the tracking and acquisition systems. These include a GPS module for initial tracking, a closed-loop machine-vision (MV) system that provides intermediate acquisition and tracking, and a tip-tilt adaptive optics (AO) system consisting of a 2-inch-diameter mirror connected to a commercial piezo tip/tilt platform.
“We’re reaching the limits in what we can do, at least not without a lot of pain, in communicating using radio frequencies. So we will likely adopt new optical technologies. And I don’t see any obvious showstoppers to further advances using the researchers’ approach.” —Alan Willner
“The tip/tilt AO system operates at 200 hertz,” says Dix-Matthews. “It plays a dual role of correcting beam wander of the outgoing beam to maintain pointing accuracy, and it also corrects the angle of arrival of the return beam to maintain fiber-coupling efficiency.”
Given the challenges “of tracking and dealing with turbulence, coupling light into a single-mode fiber is no easy matter,” says Willner. “That the researchers are able to do so is noteworthy.”
To test the technology, Walsh says they set up the terminal on the roof of the Institute’s physics building, 34 meters above sea level. To simulate the angular motion of a LEO satellite, they employed a drone outfitted with a gimbal-mounted corner cube retroreflector that returns the 1,550-nm signal, four green beacon LEDs for machine-vision tracking, and a camera for orienting the gimbal. Also included is GPS and a barometric altimeter to relay initial coordinates to the optical terminal.
The drone flew at an altitude of 120 meters at a line-of-sight distance of up to 700 meters for a laser-beam-folded link length of 1.4 kilometers. Initially, the gimbal was adjusted manually by the pilot so that the beacons were oriented toward the mount. At the next stage, the GPS module transmitted the drone’s position to the terminal computer, which enabled software to point the terminal at the target. With the target located, the MV loop closed and the mount-pointing was adjusted to track the drone beacons. The tip/tilt loop was then closed to provide fine-scale tracking. The MV and tip/tilt loops were run concurrently to maintain tracking and to correct for beam wander and wind buffeting.
“We conducted some 30 test flights, flying the drone in passes simulating the tracking rates needed for free-space optical links to satellites in LEO,” says Walsh. “And in spite of atmospheric turbulence and macroscopic motion, we were able to sustain a 100-gigabit-per-second link.”
“There’s a good reason why space agencies and major corporations are interested in free-space optical communications,” says Willner. “We’re reaching the limits in what we can do, at least not without a lot of pain, in communicating using radio frequencies. So we will likely adopt new optical technologies. And I don’t see any obvious showstoppers to further advances using the researchers approach.”
The terminal needs to be optimized further, and the MV system will require changes for satellite use. Walsh says the next step is to test the technology with an aircraft flying at higher altitudes and after that, testing with a satellite would begin.
In addition, the researchers are developing a purpose-built optical-communications ground station that they believe will lead to the commercialization of the technology. To this end, they are working with three space-related companies in Australia, says Walsh. “So we anticipate receiving our first LEO downlink sometime in 2023, and hope to provide commercial high-data-rate coherent optical communications to and from space in the next few years.”

Armageddon ruined everything. Armageddon—the 1998 movie, not the mythical battlefield—told the story of an asteroid headed straight for Earth, and a bunch of swaggering roughnecks sent in space shuttles to blow it up with a nuclear weapon.
“Armageddon is big and noisy and stupid and shameless, and it’s going to be huge at the box office,” wrote Jay Carr of the Boston Globe.
Carr was right—the film was the year’s second biggest hit (after Titanic)—and ever since, scientists have had to explain, patiently, that cluttering space with radioactive debris may not be the best way to protect ourselves. NASA is now trying a slightly less dramatic approach with a robotic mission called DART—short for Double Asteroid Redirection Test. On Monday at 7:14 p.m. EDT, if all goes well, the little spacecraft will crash into an asteroid called Dimorphos, about 11 million kilometers from Earth. Dimorphos is about 160 meters across, and orbits a 780-meter asteroid, 65803 Didymos. NASA TV plans to cover it live.
DART’s end will be violent, but not blockbuster-movie-violent. Music won’t swell and girlfriends back on Earth won’t swoon. Mission managers hope the spacecraft, with a mass of about 600 kilograms, hitting at 22,000 km/h, will nudge the asteroid slightly in its orbit, just enough to prove that it’s technologically possible in case a future asteroid has Earth in its crosshairs.
“Maybe once a century or so, there’ll be an asteroid sizeable enough that we’d like to certainly know, ahead of time, if it was going to impact,” says Lindley Johnson, who has the title of planetary defense officer at NASA.
“If you just take a hair off the orbital velocity, you’ve changed the orbit of the asteroid so that what would have been impact three or four years down the road is now a complete miss.”
So take that, Hollywood! If DART succeeds, it will show there are better fuels to protect Earth than testosterone.
The risk of a comet or asteroid that wipes out civilization is really very small, but large enough that policymakers take it seriously. NASA, ordered by the U.S. Congress in 2005 to scan the inner solar system for hazards, has found nearly 900 so-called NEOs—near-Earth objects—at least a kilometer across, more than 95 percent of all in that size range that probably exist. It has plotted their orbits far into the future, and none of them stand more than a fraction of a percent chance of hitting Earth in this millennium.
The DART spacecraft should crash into the asteroid Dimorphos and slow it in its orbit around the larger asteroid Didymos. The LICIACube cubesat will fly in formation to take images of the impact.Johns Hopkins APL/NASA
But there are smaller NEOs, perhaps 140 meters or more in diameter, too small to end civilization but large enough to cause mass destruction if they hit a populated area. There may be 25,000 that come within 50 million km of Earth’s orbit, and NASA estimates telescopes have only found about 40 percent of them. That’s why scientists want to expand the search for them and have good ways to deal with them if necessary. DART is the first test.
NASA takes pains to say this is a low-risk mission. Didymos and Dimorphos never cross Earth’s orbit, and computer simulations show that no matter where or how hard DART hits, it cannot possibly divert either one enough to put Earth in danger. Scientists want to see if DART can alter Dimorphos’s speed by perhaps a few centimeters per second.
The DART spacecraft, a 1-meter cube with two long solar panels, is elegantly simple, equipped with a telescope called DRACO, hydrazine maneuvering thrusters, a xenon-fueled ion engine and a navigation system called SMART Nav. It was launched by a SpaceX rocket in November. About 4 hours and 90,000 km before the hoped-for impact, SMART Nav will take over control of the spacecraft, using optical images from the telescope. Didymos, the larger object, should be a point of light by then; Dimorphos, the intended target, will probably not appear as more than one pixel until about 50 minutes before impact. DART will send one image per second back to Earth, but the spacecraft is autonomous; signals from the ground, 38 light-seconds away, would be useless for steering as the ship races in.
The DART spacecraft separated from its SpaceX Falcon 9 launch vehicle, 55 minutes after liftoff from Vandenberg Space Force Base, in California, 24 November 2021. In this image from the rocket, the spacecraft had not yet unfurled its solar panels.NASA
What’s more, nobody knows the shape or consistency of little Dimorphos. Is it a solid boulder or a loose cluster of rubble? Is it smooth or craggy, round or elongated? “We’re trying to hit the center,” says Evan Smith, the deputy mission systems engineer at the Johns Hopkins Applied Physics Laboratory, which is running DART. “We don’t want to overcorrect for some mountain or crater on one side that’s throwing an odd shadow or something.”
So on final approach, DART will cover 800 km without any steering. Thruster firings could blur the last images of Dimorphos’s surface, which scientists want to study. Impact should be imaged from about 50 km away by an Italian-made minisatellite, called LICIACube, which DART released two weeks ago.
“In the minutes following impact, I know everybody is going be high fiving on the engineering side,” said Tom Statler, DART’s program scientist at NASA, “but I’m going be imagining all the cool stuff that is actually going on on the asteroid, with a crater being dug and ejecta being blasted off.”
There is, of course, a possibility that DART will miss, in which case there should be enough fuel on board to allow engineers to go after a backup target. But an advantage of the Didymos-Dimorphos pair is that it should help in calculating how much effect the impact had. Telescopes on Earth (plus the Hubble and Webb space telescopes) may struggle to measure infinitesimal changes in the orbit of Dimorphos around the sun; it should be easier to see how much its orbit around Didymos is affected. The simplest measurement may be of the changing brightness of the double asteroid, as Dimorphos moves in front of or behind its partner, perhaps more quickly or slowly than it did before impact.
“We are moving an asteroid,” said Statler. “We are changing the motion of a natural celestial body in space. Humanity’s never done that before.”

Each contender is taking a different approach to space-based cellular service. The Apple offering uses the existing satellite bandwidth Globalstar once used for messaging offerings, but without the need for a satellite-specific handset. The AST project and another company, Lynk Global, would use a dedicated network of satellites with larger-than-normal antennas to produce a 4G, 5G, and someday 6G cellular signal compatible with any existing 4G-compatible phone (as detailed in other recent IEEESpectrum coverage of space-based 5G offerings). Assuming regulatory approval is forthcoming, the technology would work first in equatorial regions and then across more of the planet as these providers expand their satellite constellations. T-Mobile and Starlink’s offering would work in the former PCS band in the United States. SpaceX, like AST and Lynk, would need to negotiate access to spectrum on a country-by-country basis.
Apple’s competitors are unlikely to see commercial operations before 2024.
“Regulators have not decided on the power limits from space, what concerns there are about interference, especially across national borders. There’s a whole bunch of regulatory issues that simply haven’t been thought about to date.” —Tim Farrar, telecommunications consultant
The T-Mobile–Starlink announcement is “in some ways an endorsement” of AST and Lynk’s proposition, and “in other ways a great threat,” says telecommunications consultant Tim Farrar of Tim Farrar Associates in Menlo Park, Calif. AST and Lynk have so far told investors they expect their national mobile network operator partners to charge per use or per day, but T-Mobile announced that they plan to include satellite messaging in the 1,900-megahertz range in their existing services. Apple said their Emergency SOS via Satellite service would be free the first two years for U.S. and Canadian iPhone 14 buyers, but did not say what it would cost after that. For now, the Globalstar satellites it is using cannot offer the kind of broadband bandwidth AST has promised, but Globalstar has reported to investors orders for new satellites that might offer new capabilities, including new gateways.
Even under the best conditions—a clear view of the sky—users will need 15 seconds to send a message via Apple’s service. They will also have to follow onscreen guidance to keep the device pointed at the satellites they are using. Light foliage can cause the same message to take more than a minute to send. Ashley Williams, a satellite engineer at Apple who recorded the service’s announcement, also mentioned a data-compression algorithm and a series of rescue-related suggested auto-replies intended to minimize the amount of data that users would need to send during a rescue.
Meanwhile, AST SpaceMobile says it aims to launch an experimental satellite Saturday, 10 September, to test its cellular broadband offering.
Last month’s T-Mobile-SpaceX announcement “helped the world focus attention on the huge market opportunity for SpaceMobile, the only planned space-based cellular broadband network. BlueWalker 3, which has a 693 sq ft array, is scheduled for launch within weeks!” tweeted AST SpaceMobile CEO Abel Avellan on 25 August. The size of the array matters because AST SpaceMobile has so far indicated in its applications for experimental satellite licenses that it intends to use lower radio frequencies (700–900 MHz) with less propagation loss but that require antennas much larger than conventional satellites carry.
So far government agencies have issued licenses for thousands of low-Earth-orbiting satellites, which have the biggest impact on astronomers. Even with the constellations starting to form, satellite-cellular telecommunications companies are still open to big regulatory risks. “Regulators have not decided on the power limits from space, what concerns there are about interference, especially across national borders. There’s a whole bunch of regulatory issues that simply haven’t been thought about to date,” Farrar says.
James Webb Space Telescope (JWST) reveals its first images on 12 July, they will be the by-product of carefully crafted mirrors and scientific instruments. But all of its data-collecting prowess would be moot without the spacecraft’s communications subsystem.
The Webb’s comms aren’t flashy. Rather, the data and communication systems are designed to be incredibly, unquestionably dependable and reliable. And while some aspects of them are relatively new—it’s the first mission to use
Ka-band frequencies for such high data rates so far from Earth, for example—above all else, JWST’s comms provide the foundation upon which JWST’s scientific endeavors sit.
As previous articles in this series have noted, JWST is parked at
Lagrange point L2. It’s a point of gravitational equilibrium located about 1.5 million kilometers beyond Earth on a straight line between the planet and the sun. It’s an ideal location for JWST to observe the universe without obstruction and with minimal orbital adjustments.
Being so far away from Earth, however, means that data has farther to travel to make it back in one piece. It also means the communications subsystem needs to be reliable, because the prospect of a repair mission being sent to address a problem is, for the near term at least, highly unlikely. Given the cost and time involved, says
Michael Menzel, the mission systems engineer for JWST, “I would not encourage a rendezvous and servicing mission unless something went wildly wrong.”
According to Menzel, who has worked on JWST in some capacity for over 20 years, the plan has always been to use well-understood K
a-band frequencies for the bulky transmissions of scientific data. Specifically, JWST is transmitting data back to Earth on a 25.9-gigahertz channel at up to 28 megabits per second. The Ka-band is a portion of the broader K-band (another portion, the Ku-band, was also considered).
The Lagrange points are equilibrium locations where competing gravitational tugs on an object net out to zero. JWST is one of three craft currently occupying L2 (Shown here at an exaggerated distance from Earth). IEEE Spectrum
Both the data-collection and transmission rates of JWST dwarf those of the older
Hubble Space Telescope. Compared to Hubble, which is still active and generates 1 to 2 gigabytes of data daily, JWST can produce up to 57 GB each day (although that amount is dependent on what observations are scheduled).
Menzel says he first saw the frequency selection proposals for JWST around 2000, when he was working at
Northrop Grumman. He became the mission systems engineer in 2004. “I knew where the risks were in this mission. And I wanted to make sure that we didn’t get any new risks,” he says.
a-band frequencies can transmit more data than X-band (7 to 11.2 GHz) or S-band (2 to 4 GHz), common choices for craft in deep space. A high data rate is a necessity for the scientific work JWST will be undertaking. In addition, according to Carl Hansen, a flight systems engineer at the Space Telescope Science Institute (the science operations center for JWST), a comparable X-band antenna would be so large that the spacecraft would have trouble remaining steady for imaging.
Although the 25.9-GHz K
a-band frequency is the telescope’s workhorse communication channel, it also employs two channels in the S-band. One is the 2.09-GHz uplink that ferries future transmission and scientific observation schedules to the telescope at 16 kilobits per second. The other is the 2.27-GHz, 40-kb/s downlink over which the telescope transmits engineering data—including its operational status, systems health, and other information concerning the telescope’s day-to-day activities.
Any scientific data the JWST collects during its lifetime will need to be stored on board, because the spacecraft doesn’t maintain round-the-clock contact with Earth. Data gathered from its scientific instruments, once collected, is stored within the spacecraft’s 68-GB solid-state drive (3 percent is reserved for engineering and telemetry data).
Alex Hunter, also a flight systems engineer at the Space Telescope Science Institute, says that by the end of JWST’s 10-year mission life, they expect to be down to about 60 GB because of deep-space radiation and wear and tear.
The onboard storage is enough to collect data for about 24 hours before it runs out of room. Well before that becomes an issue, JWST will have scheduled opportunities to beam that invaluable data to Earth.
Sandy Kwan, a DSN systems engineer, says that contact windows with spacecraft are scheduled 12 to 20 weeks in advance. JWST had a greater number of scheduled contact windows during its commissioning phase, as instruments were brought on line, checked, and calibrated. Most of that process required real-time communication with Earth.
All of the communications channels use the
Reed-Solomonerror-correction protocol—the same error-correction standard as used in DVDs and Blu-ray discs as well as QR codes. The lower data-rate S-band channels use binary phase-shift key modulation—involving phase shifting of a signal’s carrier wave. The K-band channel, however, uses a quadrature phase-shift key modulation. Quadrature phase-shift keying can double a channel’s data rate, at the cost of more complicated transmitters and receivers.
JWST’s communications with Earth incorporate an acknowledgement protocol—only after the JWST gets confirmation that a file has been successfully received will it go ahead and delete its copy of the data to clear up space.
The communications subsystem was assembled along with the rest of the spacecraft bus by
Northrop Grumman, using off-the-shelf components sourced from multiple manufacturers.
JWST has had a long and
often-delayed development, but its communications system has always been a bedrock for the rest of the project. Keeping at least one system dependable means it’s one less thing to worry about. Menzel can remember, for instance, ideas for laser-based optical systems that were invariably rejected. “I can count at least two times where I had been approached by people who wanted to experiment with optical communications,” says Menzel. “Each time they came to me, I sent them away with the old ‘Thank you, but I don’t need it. And I don’t want it.’”

A rocket built by Indian startup Skyroot has become the country’s first privately developed launch vehicle to reach space, following a successful maiden flight earlier today. The suborbital mission is a major milestone for India’s private space industry, say experts, though more needs to be done to nurture the fledgling sector.
In the longer run, India’s space industry has ambitions of capturing a significant chunk of the global launch market.
Pawan Kumar Chandana, cofounder of the Hyderabad-based startup, says the success of the launch is a major victory for India’s nascent space industry, but the buildup to the mission was nerve-racking. “We were pretty confident on the vehicle, but, as you know, rockets are very notorious for failure,” he says. “Especially in the last 10 seconds of countdown, the heartbeat was racing up. But once the vehicle had crossed the launcher and then went into the stable trajectory, I think that was the moment of celebration.”
At just 6 meters (20 feet) long and weighing only around 550 kilograms (0.6 tonnes), the Vikram-S is not designed for commercial use. Today’s mission, called Prarambh, which means “the beginning” in Sanskrit, was designed to test key technologies that will be used to build the startup’s first orbital rocket, the Vikram I. The rocket will reportedly be capable of lofting as much as 480 kg up to an 500-km altitude and is slated for a maiden launch next October.

In particular, the mission has validated Skyroot’s decision to go with a novel all-carbon fiber structure to cut down on weight, says Chandana. It also allowed the company to test 3D-printed thrusters, which were used for spin stabilization in Vikram-S but will power the upper stages of its later rockets. Perhaps the most valuable lesson, though, says Chandana, was the complexity of interfacing Skyroot's vehicle with ISRO’s launch infrastructure. “You can manufacture the rocket, but launching it is a different ball game,” he says. “That was a great learning experience for us and will really help us accelerate our orbital vehicle.”
Skyroot is one of several Indian space startups looking to capitalize on recent efforts by the Indian government to liberalize its highly regulated space sector. Due to the dual-use nature of space technology, ISRO has historically had a government-sanctioned monopoly on most space activities, says Rajeswari Pillai Rajagopalan, director of the Centre for Security, Strategy and Technology at the Observer Research Foundation think tank, in New Delhi. While major Indian engineering players like Larsen & Toubro and Godrej Aerospace have long supplied ISRO with components and even entire space systems, the relationship has been one of a supplier and vendor, she says.
But in 2020, Finance Minister Nirmala Sitharaman announced a series of reforms to allow private players to build satellites and launch vehicles, carry out launches, and provide space-based services. The government also created the Indian National Space Promotion and Authorisation Centre (InSpace), a new agency designed to act as a link between ISRO and the private sector, and affirmed that private companies would be able to take advantage of ISRO’s facilities.
The first launch of a private rocket from an ISRO spaceport is a major milestone for the Indian space industry, says Rajagopalan. “This step itself is pretty crucial, and it’s encouraging to other companies who are looking at this with a lot of enthusiasm and excitement,” she says. But more needs to be done to realize the government’s promised reforms, she adds. The Space Activities Bill that is designed to enshrine the country’s space policy in legislation has been languishing in draft form for years, and without regulatory clarity, it’s hard for the private sector to justify significant investments. “These are big, bold statements, but these need to be translated into actual policy and regulatory mechanisms,” says Rajagopalan.
Skyroot’s launch undoubtedly signals the growing maturity of India’s space industry, says Saurabh Kapil, associate director in PwC’s space practice. “It’s a critical message to the Indian space ecosystem, that we can do it, we have the necessary skill set, we have those engineering capabilities, we have those manufacturing or industrialization capabilities,” he says.

However, crossing this technical milestone is only part of the challenge, he says. The industry also needs to demonstrate a clear market for the kind of launch vehicles that companies like Skyroot are building. While private players are showing interest in launching small satellites for applications like agriculture and infrastructure monitoring, he says, these companies will be able to build sustainable businesses only if they are allowed to compete for more lucrative government and defense-sector contacts.
In the longer run, though, India’s space industry has ambitions of capturing a significant chunk of the global launch market, says Kapil. ISRO has already developed a reputation for both reliability and low cost—its 2014 mission to Mars cost just US $74 million, one-ninth the cost of a NASA Mars mission launched the same week. That is likely to translate to India’s private space industry, too, thanks to a considerably lower cost of skilled labor, land, and materials compared with those of other spacefaring nations, says Kapil. “The optimism is definitely there that because we are low on cost and high on reliability, whoever wants to build and launch small satellites is largely going to come to India,” he says.
