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.

Leaked tax records suggest subsidiaries of international gas field contractors continued to make millions after the coup
In the two years since a murderous junta launched a coup in Myanmar, some of the world’s biggest oil and gas service companies continued to make millions of dollars from operations that have helped prop up the military regime, tax documents seen by the Guardian suggest.
US oil services giant Halliburton’s Singapore-based subsidiaryMyanmar Energy Services reported pre-tax profits of $6.3m in Myanmar in the year to September 2021, which includes eight months while the junta was in power.

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.

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.

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.

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.

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.”

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.

This past weekend, NASA scrubbed the Artemis I uncrewed mission to the moon and back. Reportedly, the space agency will try again to launch the inaugural moon mission featuring the gargantuan Space Launch System (SLS) at the end of this month or sometime in October. Meanwhile, half a world away, China is progressing on its own step-by-step program to put both robotic and, eventually, crewed spacecraft on the lunar surface and keep pace with NASA-led achievements.
Asia’s rapidly growing space power has already made a number of impressive lunar leaps but will need to build on these in the coming years. Ambitious sample-return missions, landings at the lunar south pole, testing the ability to 3D print using materials from regolith, and finally sending astronauts on a short-term visit to our celestial neighbor are in the cards before the end of the decade.
The next step, expected around 2024, is Chang’e-6: an unprecedented attempt to collect rock samples from the far side of the moon.
The mission will build on two recent major space achievements. In 2019, China became the first country to safely land a spacecraft on the far side of the moon, a hemisphere which cannot be seen from Earth—as the moon is tidally locked. The mission was made possible by a relay satellite out beyond the moon at Earth-moon Lagrange point 2, where it can bounce signals between Chang’e-4 and ground stations in China.
Chang’e-5 in 2020 performed the first sampling of lunar material in over four decades. The complex, four-spacecraft mission used an orbiter, lander, ascent vehicle, and return capsule to successfully deliver 1.731 grams of lunar rocks to Earth. The automated rendezvous and docking in lunar orbit of the orbiter and ascent spacecraft was also seen as a test of the technology for getting astronauts off the moon and back to Earth.
Chang’e-6 will again attempt to collect new samples, this time from the South pole-Aitken basin, a massive and ancient impact crater on the far side of the moon. The science return of such a mission could likewise be huge as its rocks have the potential to answer some significant questions about the moon’s geological past, says planetary scientist Katherine Joy of the University of Manchester, in England.
“We think that the basin-formation event was so large that the moon’s mantle could have been excavated from tens of kilometers deep,” says Joy. Fragments of this mantle material originating from deep in the moon would help us to understand how the Moon differentiated early in its history, the nature of its interior, and how volcanism on the far side of the moon is different or similar to that on the nearside.
Chang’e-7, also scheduled for 2024, will look at a different set of questions geared toward lunar resources. It will target the lunar south pole, a region where NASA’s Artemis 3 crewed mission is also looking to land.
The mission will involve a flotilla of spacecraft, including a new relay satellite, an orbiter, lander, rover and a small “hopping” spacecraft designed to inspect permanently shadowed craters which are thought to contain water ice which could be used in the future to provide breathable oxygen, rocket fuel, or drinking water to lunar explorers.
Following this Chang’e-8 is expected to launch around 2027 to test in situ resource utilization and conduct other experiments and technology tests such as oxygen extraction and 3D printing related to building a permanent lunar base—for both robots and crew—in the 2030s, named the International Lunar Research Station (ILRS).
The upcoming Chang’e-6, 7 and 8 missions are expected to launch on China’s largest current rocket, the Long March 5. But, as with NASA and Artemis, China will need its own megarockets to make human lunar exploration and ultimately, perhaps, crewed lunar bases a reality.
In part in reaction to the achievements of SpaceX, the China Aerospace Science and Technology Corporation (CASC), the country’s main space contractor, is developing a new rocket specifically for launching astronauts beyond low Earth orbit.
The “new generation crew launch vehicle” will essentially bundle three Long March 5 core stages together (which will be no mean feat of engineering) while also improving the performance of its kerosene engines. The result will be a roughly 90-meter-tall rocket resembling a Long March version of SpaceX’s Falcon Heavy, capable of sending 27 tonnes of payload into translunar injection.
Two launches of the rocket will by 2030, according to leading Chinese space officials, be able to put a pair of astronauts on the moon for a 6-hour stay. Such a mission also requires developing a lunar lander and a new spacecraft capable of keeping astronauts safe in deep space.
For building infrastructure on the moon, China is looking to the future Long March 9, an SLS-class rocket capable of sending 50 tonnes into translunar injection. The project will require CASC to make breakthroughs in a number of areas, including manufacturing new, wider rocket bodies of up to 10 meters in diameter, mastering massive, higher-thrust rocket engines, and building a new launch complex at Wenchang, Hainan island, to handle the monster.
Once again NASA is leading humanity’s journey to the moon, but China’s steady accumulation of capabilities and long-term ambitions means it will likely not be far behind.

Update 5 Sept.: For now, NASA’s giant Artemis I remains on the ground after two launch attempts scrubbed by a hydrogen leak and a balky engine sensor. Mission managers say Artemis will fly when everything's ready—but haven't yet specified whether that might be in late September or in mid-October.
“When you look at the rocket, it looks almost retro,” said Bill Nelson, the administrator of NASA. “Looks like we’re looking back toward the Saturn V. But it’s a totally different, new, highly sophisticated—more sophisticated—rocket, and spacecraft.”
Artemis, powered by the Space Launch System rocket, is America’s first attempt to send astronauts to the moon since Apollo 17 in 1972, and technology has taken giant leaps since then. On Artemis I, the first test flight, mission managers say they are taking the SLS, with its uncrewed Orion spacecraft up top, and “stressing it beyond what it is designed for”—the better to ensure safe flights when astronauts make their first landings, currently targeted to begin with Artemis III in 2025.
But Nelson is right: The rocket is retro in many ways, borrowing heavily from the space shuttles America flew for 30 years, and from the Apollo-Saturn V.
Much of Artemis’s hardware is refurbished: Its four main engines, and parts of its two strap-on boosters, all flew before on shuttle missions. The rocket’s apricot color comes from spray-on insulation much like the foam on the shuttle’s external tank. And the large maneuvering engine in Orion’s service module is actually 40 years old—used on 19 space shuttle flights between 1984 and 1992.
“I have a name for missions that use too much new technology—failures.” —John Casani, NASA
Perhaps more important, the project inherits basic engineering from half a century of spaceflight. Just look at Orion’s crew capsule—a truncated cone, somewhat larger than the Apollo Command Module but conceptually very similar.
Old, of course, does not mean bad. NASA says there is no need to reinvent things engineers got right the first time.
“There are certain fundamental aspects of deep-space exploration that are really independent of money,” says Jim Geffre, Orion vehicle-integration manager at the Johnson Space Center in Houston. “The laws of physics haven’t changed since the 1960s. And capsule shapes happen to be really good for coming back into the atmosphere at Mach 32.”
Roger Launius, who served as NASA’s chief historian from 1990 to 2002 and as a curator at the Smithsonian Institution from then until 2017, tells of a conversation he had with John Casani, a veteran NASA engineer who managed the Voyager, Galileo, and Cassini probes to the outer planets.
“I have a name for missions that use too much new technology,” he recalls Casani saying. “Failures.”
The Artemis I flight is slated for about six weeks. (Apollo 11 lasted eight days.) The ship roughly follows Apollo’s path to the moon’s vicinity, but then puts itself in what NASA calls a distant retrograde orbit. It swoops within 110 kilometers of the lunar surface for a gravity assist, then heads 64,000 km out—taking more than a month but using less fuel than it would in closer orbits. Finally, it comes home, reentering the Earth’s atmosphere at 11 km per second, slowing itself with a heatshield and parachutes, and splashing down in the Pacific not far from San Diego.
If all four, quadruply redundant flight computer modules fail, there is a fifth, entirely separate computer onboard, running different code to get the spacecraft home.
“That extra time in space,” says Geffre, “allows us to operate the systems, give more time in deep space, and all those things that stress it, like radiation and micrometeoroids, thermal environments.”
There are, of course, newer technologies on board. Orion is controlled by two vehicle-management computers, each composed of two flight computer modules (FCMs) to handle guidance, navigation, propulsion, communications, and other systems. The flight control system, Geffre points out, is quad-redundant; if at any point one of the four FCMs disagrees with the others, it will take itself offline and, in a 22-second process, reset itself to make sure its outputs are consistent with the others’. If all four FCMs fail, there is a fifth, entirely separate computer running different code to get the spacecraft home.
Guidance and navigation, too, have advanced since the sextant used on Apollo. Orion uses a star tracker to determine its attitude, imaging stars and comparing them to an onboard database. And an optical navigation camera shoots Earth and the moon so that guidance software can determine their distance and position and keep the spacecraft on course. NASA says it’s there as backup, able to get Orion to a safe splashdown even if all communication with Earth has been lost.
But even those systems aren’t entirely new. Geffre points out that the guidance system’s architecture is derived from the Boeing 787. Computing power in deep space is limited by cosmic radiation, which can corrupt the output of microprocessors beyond the protection of Earth’s atmosphere and magnetic field.
Beyond that is the inevitable issue of cost. Artemis is a giant project, years behind schedule, started long before NASA began to buy other launches from companies like SpaceX and Rocket Lab. NASA’s inspector general, Paul Martin, testified to Congressin March that the first four Artemis missions would cost US $4.1 billion each—“a price tag that strikes us as unsustainable.”
Launius, for one, rejects the argument that government is inherently wasteful. “Yes, NASA’s had problems in managing programs in the past. Who hasn’t?” he says. He points out that Blue Origin and SpaceX have had plenty of setbacks of their own—they’re just not obliged to be public about them. “I could go on and on. It’s not a government thing per se and it’s not a NASA thing per se.”
So why return to the moon with—please forgive the pun—such a retro rocket? Partly, say those who watch Artemis closely, because it’s become too big to fail, with so much American money and brainpower invested in it. Partly because it turns NASA’s astronauts outward again, exploring instead of maintaining a space station. Partly because new perspectives could come of it. And partly because China and Russia have ambitions in space that threaten America’s.
“Apollo was a demonstration of technological verisimilitude—to the whole world,” says Launius. “And the whole world knew then, as they know today, that the future belongs to the civilization that can master science and technology.”
Update 7 Sept.: Artemis I has been on launchpad 39B, not 39A as previously reported, at Kennedy Space Center.

The orbiting Tiangong-2 space lab has transmitted quantum-encryption keys to four ground stations, researchers reported on 18 August. The same network of ground stations is also able to receive quantum keys from the orbiting Micius satellite, which is in a much higher orbit, using the space station as a repeater. It comes just after the late July launch of Jinan 1, China’s second quantum-encrypting satellite, by the University of Science and Technology of China. USTC told the Xinhua News Agency that the new satellite is one-sixth the mass of its 2016 predecessor.
“The launch is significant,” says physicist Paul Kwiat of the University of Illinois in Urbana-Champaign, because it means the team are starting to build, not just plan, a quantum network. USTC researchers did not reply to IEEE Spectrum’s request for comments.
In quantum-key distribution (QKD), the quantum states of a single photon, such as polarization, encode and distribute random information that can be used to encrypt a classical message. Because it is impossible to copy the quantum state without changing it, senders and recipients can verify that their transmission got through without tampering or reading by third parties. In some scenarios it involves sending just one well-described photon at a time, but single photons are difficult to produce, and in this case, researchers used an attenuated laser to send small pulses that might also come out a couple of photons at a time, or not at all.
The USTC research team, led by Jian-Wei Pan, had already established quantum-key distribution from Micius to a single ground station in 2017, not long after the 2016 launch of the satellite. The work that Pan and colleagues reported this month, but which took place in 2018 and 2019, is a necessary step for building a constellation of quantum-encryption-compatible satellites across a range of orbits, to ensure more secure long-distance communications.
Several other research groups have transmitted quantum keys, and others are now building microsatellites for the same purpose. However, the U.S. National Security Agency’s site about QKD lists several technical limitations, such as requiring an initial verification of the counterparty’s identity, the need for special equipment, the cost, and the risk of hardware-based security vulnerabilities. In the absence of fixes, the NSA does not anticipate approving QKD for national security communications.
“A quantum network with entangled nodes is the thing that would be really interesting, enabling distributed quantum computing and sensing, but that’s a hard thing to make. Being able to do QKD is a necessary but not sufficient first step,” Kwiat says. The USTC experiments are a chance to establish many technical abilities, such as the precise control of the pulse duration and direction of the lasers involved, or the ability to accurately transfer and measure the quantum signals to the standard necessary for a more complex quantum network.
That is a step ahead of the many other QKD efforts made so far on laboratory benchtops, over ground-to-ground cables, or aboard balloons or aircraft. “You have to do things very differently if you’re not allowed to fiddle with something once it’s launched into space,” Kwiat says.

With the historic Kunming-Montreal Agreement of 18 December 2022, more than 200 countries agreed to halt and reverse biodiversity loss. But becoming nature-positive is an ambitious goal, also held back by the lack of efficient and accurate tools to capture snapshots of global biodiversity. This is a task where robots, in combination with environmental DNA (eDNA) technologies, can make a difference.
Our recent findings show a new way to sample surface eDNA with a drone, which could be helpful in monitoring biodiversity in terrestrial ecosystems. The eDrone can land on branches and collect eDNA from the bark using a sticky surface. The eDrone collected surface eDNA from the bark of seven different trees, and by sequencing the collected eDNA we were able to identify 21 taxa, including insects, mammals, and birds.
How can we bring limbed robots into real-world environments to complete challenging tasks? Dr. Dimitrios Kanoulas and the team at UCL Computer Science’s Robot Perception and Learning Lab are exploring how we can use autonomous and semi-autonomous robots to work in environments that humans cannot.
