Roomba Maker 'iRobot' Files for Bankruptcy After 35 Years
Roomba manufacturer iRobot filed for bankruptcy today, reports Bloomberg. After 35 years, iRobot reached a "restructuring support agrement that will hand control of the consumer robot maker to Shenzhen PICEA Robotics Co, its main supplier and lender, and Santrum Hong Kong Compny."Under the restructuring, vacuum cleaner maker Shenzhen PICEA will receive the entire equity stake in the reorganised company... The plan will allow the debtor to remain as a going concern and continue to meet its commitments to employees and make timely payments in full to vendors and other creditors for amounts owed throughout the court-supervised process, according to an iRobot statement... he company warned of potential bankruptcy in December after years of declining earnings. Roomba says it's sold over 50 million robots, the article points out, but earnings "began to decline since 2021 due to supply chain headwinds and increased competition. "A hoped-for by acquisition by Amazon.com in 2023 collapsed over regulatory concerns."

America Adds 11.7 GW of New Solar Capacity in Q3 - Third Largest Quarter on Record
America's solar industry "just delivered another huge quarter," reports Electrek, "installing 11.7 gigawatts (GW) of new capacity in Q3 2025. That makes it the third-largest quarter on record and pushes total solar additions this year past 30 GW..."According to the new "US Solar Market Insight Q4 2025" report from Solar Energy Industries Association (SEIA) and Wood Mackenzie, 85% of all new power added to the grid during the first nine months of the Trump administration came from solar and storage. And here's the twist: Most of that growth — 73% — happened in red [Republican-leaning] states. Eight of the top 10 states for new installations fall into that category, including Texas, Indiana, Florida, Arizona, Ohio, Utah, Kentucky, and Arkansas... Two new solar module factories opened this year in Louisiana and South Carolina, adding a combined 4.7 GW of capacity. That brings the total new U.S. module manufacturing capacity added in 2025 to 17.7 GW. With a new wafer facility coming online in Michigan in Q3, the U.S. can now produce every major component of the solar module supply chain... SEIA also noted that, following an analysis of EIA data, it found that more than 73 GW of solar projects across the U.S. are stuck in permitting limbo and at risk of politically motivated delays or cancellations.

Trump Ban on Wind Energy Permits 'Unlawful', Court Rules
A January order blocking wind energy projects in America has now been vacated by a U.S. judge and declared unlawful, reports the Associated Press:[Judge Saris of the U.S. district court for the district of Massachusetts] ruled in favor of a coalition of state attorneys general from 17 states and Washington DC, led by Letitia James, New York's attorney general, that challenged President Trump's day one order that paused leasing and permitting for wind energy projects... The coalition that opposed Trump's order argued that Trump does not have the authority to halt project permitting, and that doing so jeopardizes the states' economies, energy mix, public health and climate goals. The coalition includes Arizona, California, Colorado, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New Mexico, New York, Oregon, Rhode Island, Washington state and Washington DC. They say they have invested hundreds of millions of dollars collectively to develop wind energy and even more on upgrading transmission lines to bring wind energy to the electrical grid... Wind is the United States' largest source of renewable energy, providing about 10% of the electricity generated in the nation, according to the American Clean Power Association. But the BBC quotes Timothy Fox, managing director at the Washington, DC-based research firm ClearView Energy Partners, as saying he doesn't expect the ruling to reinvigorate the industry: "It's more symbolic than substantive," he said. "All the court is saying is ... you need to go back to work and consider these applications. What does that really mean?" he said.Officials could still deny permits or bog applications down in lengthy reviews, he noted.

Startup Successfully Uses AI to Find New Geothermal Energy Reservoirs
A Utah-based startup announced last week it used AI to locate a 250-degree Fahrenheit geothermal reservoir, reports CNN. It'll start producing electricity in three to five years, the company estimates — and at least one geologist believes AI could be an exciting "gamechanger" for the geothermal industry.[Startup Zanskar Geothermal & Minerals] named it "Big Blind," because this kind of site — which has no visual indication of its existence, no hot springs or geysers above ground, and no history of geothermal exploration — is known as a "blind" system. It's the first industry-discovered blind site in more than three decades, said Carl Hoiland, co-founder and CEO of Zanskar. "The idea that geothermal is tapped out has been the narrative for decades," but that's far from the case, he told CNN. He believes there are many more hidden sites across the Western U.S. Geothermal energy is a potential gamechanger. It offers the tantalizing prospect of a huge source of clean energy to meet burgeoning demand. It's near limitless, produces scarcely any climate pollution, and is constantly available, unlike wind and solar, which are cheap but rely on the sun shining and the wind blowing. The problem, however, has been how to find and scale it. It requires a specific geology: underground reservoirs of hot water or steam, along with porous rocks that allow the water to move through them, heat up, and be brought to the surface where it can power turbines... The AI models Zanskar uses are fed information on where blind systems already exist. This data is plentiful as, over the last century and more, humans have accidentally stumbled on many around the world while drilling for other resources such as oil and gas. The models then scour huge amounts of data — everything from rock composition to magnetic fields — to find patterns that point to the existence of geothermal reserves. AI models have "gotten really good over the last 10 years at being able to pull those types of signals out of noise," Hoiland said... Zanskar's discovery "is very significant," said James Faulds, a professor of geosciences at Nevada Bureau of Mines and Geology.... Estimates suggest over three-quarters of US geothermal resources are blind, Faulds told CNN. "Refining methods to find such systems has the potential to unleash many tens and perhaps hundreds of gigawatts in the western US alone," he said... Big Blind is the company's first blind site discovery, but it's the third site it has drilled and hit commercial resources. "We expect dozens, to eventually hundreds, of new sites to be coming to market," Hoiland said.... Hoiland says Zanskar's work shows conventional geothermal still has huge untapped potential.

The World's Electric Car Sales Have Spiked 21% So Far in 2025
Electrek reports:EV and battery supply chain research specialists Benchmark Mineral Intelligence reports that 2.0 million electric vehicles were sold globally in November 2025, bringing global EV sales to 18.5 million units year-to-date. That's a 21% increase compared to the same period in 2024.Europe was the clear growth leader in November, while North America continued to lag following the expiration of US EV tax credits. China, meanwhile, remains the world's largest EV market by a wide margin. Europe's EV market jumped 36% year-over-year in November 2025, with BEV sales up 35% and plug-in hybrid (PHEV) sales rising 39%. That brings Europe's total EV sales to 3.8 million units for the year so far, up 33% compared to January-November 2024... In North America, EV sales in the US did tick up month-over-month in November, following a sharp October drop after federal tax credits expired on September 30, 2025. Brands including Kia (up 30%), Hyundai (up 20%), Honda (up 11%), and Subaru (232 Solterra sales versus just 13 the month before) all saw gains, but overall volumes remain below levels when the federal tax credit was still available... [North America shows a -1% drop in EV sales from January to November 2025 vs. January to November 2024] Year-to-date, EV sales in China are up 19%, with 11.6 million units sold. One of the biggest headlines out of China is exports. BYD reported a record 131,935 EV exports in November, blowing past its previous high of around 90,000 units set in June. BYD sales in Europe have jumped more than fourfold this year to around 200,000 vehicles, doubled in Southeast Asia, and climbed by more than 50% in South America... "Overall, EV demand remains resilient, supported by expanding model ranges and sustained policy incentives worldwide," said Rho Motion data manager Charles Lester. Beyond China, Europe, and North America, the rest of the world saw a 48% spike in EV sales in 2025 vs the same 11 months in 2024, representing 1.5 million EVs sold. "The takeaway: EV demand continues to grow worldwide," the article adds, "but policy support — or the lack thereof — is increasingly shaping where this growth shows up."

How a 23-Year-Old in 1975 Built the World's First Handheld Digital Camera
In 1975, 23-year-old electrical engineer Steve Sasson joined Kodak. And in a new interview with the BBC, he remembers that he'd found the whole photographic process "really annoying.... I wanted to build a camera with no moving parts. Now that was just to annoy the mechanical engineers...""You take your picture, you have to wait a long time, you have to fiddle with these chemicals. Well, you know, I was raised on Star Trek, and all the good ideas come from Star Trek. So I said what if we could just do it all electronically...?" Researchers at Bell Labs in the US had, in 1969, created a type of integrated circuit called a charge-coupled device (CCD). An electric charge could be stored on a metal-oxide semiconductor (MOS), and could be passed from one MOS to another. Its creators believed one of its applications might one day be used as part of an imaging device — though they hadn't worked out how that might happen. The CCD, nevertheless, was quickly developed. By 1974, the US microchip company Fairchild Semiconductors had built the first commercial CCD, measuring just 100 x 100 pixels — the tiny electronic samples taken of an original image. The new device's ability to capture an image was only theoretical — no-one had, as yet, tried to take an image and display it. (NASA, it turned out, was also looking at this technology, but not for consumer cameras....) The CCD circuit responded to light but could only form an image if Sasson was somehow able to attach a lens to it. He could then convert the light into digital information — a blizzard of 1s and 0s — but there was just one problem: money. "I had no money to build this thing. Nobody told me to build it, and I certainly couldn't demand any money for it," he says. "I basically stole all the parts, I was in Kodak and the apparatus division, which had a lot of parts. I stole the optical assembly from an XL movie camera downstairs in a used parts bin. I was just walking by, you see it, and you take it, you know." He was also able to source an analogue to digital converter from a $12 (about £5 in 1974) digital voltmeter, rather than spending hundreds on the part. I could manage to get all these parts without anybody really noticing," he says.... The bulky device needed a way to store the information the CCD was capturing, so Sasson used an audio cassette deck. But he also needed a way to view the image once it was saved on the magnetic tape. "We had to build a playback unit," Sasson says. "And, again, nobody asked me to do that either. So all I got to do is the reverse of what I did with the camera, and then I have to turn that digital pattern into an NTSC television signal." NTSC (National Television System Committee) was the conversion standard used by American TV sets. Sasson had to turn only 100 lines of digital code captured by the camera into the 400 lines that would form a television signal. The solution was a Motorola microprocessor, and by December 1975, the camera and its playback unit was complete, the article points out. With his colleague Jim Schueckler, Sasson had spent more than a year putting together the "increasingly bulky" device, that "looked like an oversized toaster."The camera had a shutter that would take an image at about 1/20th of a second, and — if everything worked as it should — the cassette tape would start to move as the camera transferred the stored information from its CCD [which took 23 seconds]. "It took about 23 seconds to play it back, and then about eight seconds to reconfigure it to make it look like a television signal, and send it to the TV set that I stole from another lab...." In 1978, Kodak was granted the first patent for a digital camera. It was Sasson's first invention. The patent is thought to have earned Eastman Kodak billions in licensing and infringement payments by the time they sold the rights to it, fearing bankruptcy, in 2012... As for Sasson, he never worked on anything other than the digital technology he had helped to create until he retired from Eastman Kodak in 2009.

More of America's Coal-Fired Power Plants Cease Operations
New England's last coal-fired power plant "has ceased operations three years ahead of its planned retirement date," reports the New Hampshire Bulletin. "The closure of the New Hampshire facility paves the way for its owner to press ahead with an initiative to transform the site into a clean energy complex including solar panels and battery storage systems.""The end of coal is real, and it is here," said Catherine Corkery, chapter director for Sierra Club New Hampshire. "We're really excited about the next chapter...." The closure in New Hampshire — so far undisputed by the federal government — demonstrates that prolonging operations at some facilities just doesn't make economic sense for their owners. "Coal has been incredibly challenged in the New England market for over adecade," said Dan Dolan, president of the New England Power Generators Association. Merrimack Station, a 438-megawatt power plant, came online in the1960s and provided baseload power to the New England region for decades. Gradually, though, natural gas — which is cheaper and more efficient — took over the regional market... Additionally, solar power production accelerated from 2010 on, lowering demand on the grid during the day and creating more evening peaks. Coal plants take longer to ramp up production than other sources, and are therefore less economical for these shorter bursts of demand, Dolan said. In recent years, Merrimack operated only a few weeks annually. In 2024, the plant generated just0.22% of the region's electricity. It wasn't making enough money to justify continued operations, observers said. The closure "is emblematic of the transition that has been occurring in the generation fleet in New England for many years," Dolan said. "The combination of all those factors has meant that coal facilities are no longer economic in this market." Meanwhile Los Angeles — America's second-largest city — confirmed that the last coal-fired power plant supplying its electricity stopped operations just before Thanksgiving, reports the Utah News Dispatch:Advocates from the Sierra Club highlighted in a news release that shutting down the units had no impact on customers, and questioned who should "shoulder the cost of keeping an obsolete coal facility on standby...." Before ceasing operations, the coal units had been working at low capacities for several years because the agency's users hadn't been calling on the power [said John Ward, spokesperson for Intermountain Power Agency]. The coal-powered units "had a combined capacity of around 1,800 megawatts when fully operational," notes Electrek, "and as recently as 2024, they still supplied around 11% of LA's electricity. The plant sits in Utah's Great Basin region and powered Southern California for decades." Now, for the first time, none of California's power comes from coal.There's a political hiccup with IPP, though: the Republican-controlled Utah Legislature blocked the Intermountain Power Agency from fully retiring the coal units this year, ordering that they can't be disconnected or decommissioned. But despite that mandate, no buyers have stepped forward to keep the outdated coal units online. The Los Angeles Department of Water and Power (LADWP) is transitioning to newly built, hydrogen-capable generating units at the same IPP location, part of a modernization effort called IPP Renewed. These new units currently run on natural gas, but they're designed to burn a blend of natural gas and up to 30% green hydrogen, and eventually100% green hydrogen. LADWP plans to start adding green hydrogen to the fuel mix in 2026. "With the plant now idled but legally required to remain connected, serious questions remain about who will shoulder the cost of keeping an obsolete coal facility on standby," says the Sierra Club. One of the natural gas units started commerical operations last Octoboer, with the second starting later this month, IPP spokesperson John Ward told Agency]. the Utah News Dispatch.

Germany Covers Nearly 56 Percent of 2025 Electricity Use With Renewables
Longtime Slashdot reader AmiMoJo shares a report from Clean Energy Wire: Renewable energy sources covered nearly 56 percent of Germany's gross electricity consumption in 2025, according to preliminary figures by energy industry group BDEW and research institute ZSW. Despite a 'historically weak' first quarter of the year for wind power production and a significant drop in hydropower output, the share of renewables grew by 0.7 percentage points compared to the previous year thanks to an increase in installed solar power capacity. Solar power output increased by 18.7 percent over the whole year, while the strong growth in installed capacity from previous years could be sustained, with more than 17 gigawatts (GW) added to the system. With March being the least windy month in Germany since records began in 1950, wind power output, on the other hand, faced a drop of 5.2 percent compared to 2024. However, stronger winds in the second and third quarter compensated for much of the early-year decrease. Onshore turbines with a capacity of 5.2 GW were added to the grid, a marked increase from the 3.3 GW in the previous year. Due to significantly less precipitation this year compared to 2024, hydropower output dropped by nearly one quarter (24.1%), while remaining only a fraction (3.2%) of total renewable power output.

Framework Raises DDR5 Memory Prices By 50% For DIY Laptops
Framework Computer raised DDR5 memory prices for its Laptop DIY Editions by 50% due to industry-wide memory shortages. Phoronix reports: Framework Computer is keeping the prior prices for existing pre-orders and also is foregoing any price changes for their pre-built laptops or the Framework Desktop. Framework Computer also lets you order DIY laptops without any memory at all if so desired for re-using existing modules or should you score a deal elsewhere. Due to their memory pricing said to be more competitive below market rates, they also adjusted their return policy to prevent scalpers from purchasing DIY Edition laptops with memory while then returning just the laptops. The DDR5 must be returned now with DIY laptop order returns. Additional details can be found via the Framework Blog.

RoboCrop: Teaching Robots How To Pick Tomatoes
alternative_right quotes a report from Phys.org: To teach robots how to become tomato pickers, Osaka Metropolitan University Assistant Professor Takuya Fujinaga, Graduate School of Engineering, programmed them to evaluate the ease of harvesting for each tomato before attempting to pick it. Fujinaga's new model uses image recognition paired with statistical analysis to evaluate the optimal approach direction for each fruit. The system involves image processing/vision of the fruit, its stems, and whether it is concealed behind another part of the plant. These factors inform robot control decisions and help it choose the best approach. The model represents a shift in focus from the traditional 'detection/recognition' model to what Fujinaga calls a 'harvest-ease estimation.' "This moves beyond simply asking 'can a robot pick a tomato?' to thinking about 'how likely is a successful pick?', which is more meaningful for real-world farming," he explained. When tested, Fujinaga's new model demonstrated an 81% success rate, far above predictions. Notably, about a quarter of the successes were tomatoes that were successfully harvested from the right or left side that had previously failed to be harvested by a front approach. This suggested that the robot changed its approach direction when it initially struggled to pick the fruit. "This is expected to usher in a new form of agriculture where robots and humans collaborate," said Fujinaga. "Robots will automatically harvest tomatoes that are easy to pick, while humans will handle the more challenging fruits." The findings are published in Smart Agricultural Technology.

Nvidia Can Sell H200 Chips To China For 25% US Cut
The Trump administration will allow Nvidia to resume selling H200 chips to China, but only if the U.S. government takes a 25% cut. Axios reports: Trump said on Truth Social that he'll allow Nvidia to sell H200 chips -- the generation of chips before its current, more-advanced Blackwell lineup -- to China, with the U.S. government pocketing a quarter of the revenue. He said he would apply "the same approach to AMD, Intel, and other GREAT American Companies." American defense hawks fear that China could use Nvidia chips to advance its military ambitions. Trump said Monday that the sales will be subject to "conditions that allow for continued strong National Security." The blockade remains in place for Nvidia's current generation of Blackwell chips, which will be replaced in the second half of 2026 by even more advanced Rubin chips. Huang said recently he was unsure if China would want the older chips. "We applaud President Trump's decision to allow America's chip industry to compete to support high paying jobs and manufacturing in America," Nvidia said in a statement. "Offering H200 to approved commercial customers, vetted by the Department of Commerce, strikes a thoughtful balance that is great for America."

More Than 200 Environmental Groups Demand Halt To New US Datacenters
An anonymous reader quotes a report from the Guardian: A coalition of more than 230 environmental groups has demanded a national moratorium on new datacenters in the U.S., the latest salvo in a growing backlash to a booming artificial intelligence industry that has been blamed for escalating electricity bills and worsening the climate crisis. The green groups, including Greenpeace, Friends of the Earth, Food & Water Watch and dozens of local organizations, have urged members of Congress to halt the proliferation of energy-hungry datacenters, accusing them of causing planet-heating emissions, sucking up vast amounts of water and exacerbating electricity bill increases that have hit Americans this year. "The rapid, largely unregulated rise of datacenters to fuel the AI and crypto frenzy is disrupting communities across the country and threatening Americans' economic, environmental, climate and water security," the letter states, adding that approval of new data centers should be paused until new regulations are put in place. The push comes amid a growing revolt against moves by companies such as Meta, Google and Open AI to plow hundreds of billions of dollars into new datacenters, primarily to meet the huge computing demands of AI. At least 16 datacenter projects, worth a combined $64 billion, have been blocked or delayed due to local opposition to rising electricity costs. The facilities' need for huge amounts of water to cool down equipment has also proved controversial, particularly in drier areas where supplies are scarce. [...] At the current rate of growth, datacenters could add up to 44m tons of carbon dioxide to the atmosphere by 2030, equivalent to putting an extra 10m cars on to the road and exacerbating a climate crisis that is already spurring extreme weather disasters and ripping apart the fabric of the American insurance market. But it is the impact upon power bills, rather than the climate crisis, that is causing anguish for most voters, acknowledged Emily Wurth, managing director of organizing at Food & Water Watch, the group behind the letter to lawmakers. "I've been amazed by the groundswell of grassroots, bipartisan opposition to this, in all types of communities across the US," said Wurth. "Everyone is affected by this, the opposition has been across the political spectrum. A lot of people don't see the benefits coming from AI and feel they will be paying for it with their energy bills and water." "It's an important talking point. We've seen outrageous utility price rises across the country and we are going to lean into this. Prices are going up across the board and this is something Americans really do care about."

Idaho Lab Produces World's First Molten Salt Fuel for Nuclear Reactors
America's Energy Department runs a research lab in Idaho — and this week announced successful results from a ground-breaking experiment. "This is the first time in history that chloride-based molten salt fuel has been produced for a fast reactor," says Bill Phillips, the lab's technical lead for salt synthesis. He calls it "a major milestone for American innovation and a clear signal of our national commitment to advanced nuclear energy."Unlike traditional reactors that use solid fuel rods and water as a coolant, most molten salt reactors rely on liquid fuel — a mixture of salts containing fissile material. This design allows for higher operating temperatures, better fuel efficiency, and enhanced safety. It also opens the door to new applications, including compact nuclear systems for ships and remote installations. "The Molten Chloride Fast Reactor represents a paradigm shift in the nuclear fuel cycle, and the Molten Chloride Reactor Experiment (MCRE) will directly inform the commercialization of that reactor," said Jeff Latkowski, senior vice president of TerraPower and program director for the Molten Chloride Fast Reactor. "Working with world-leading organizations such as INL to successfully synthesize this unique new fuel demonstrates how real progress in Gen IV nuclear is being made together." "The implications for the maritime industry are significant," said Don Wood, senior technical advisor for MCRE. "Molten salt reactors could provide ships with highly efficient, low-maintenance nuclear power, reducing emissions and enabling long-range, uninterrupted travel. The technology could spark the rise of a new nuclear sector — one that is mobile, scalable and globally transformative. More details from America's Energy Department:MCRE will require a total of 72 to 75 batches of fuel salt to go critical, making it the largest fuel production effort at INL since the operations of Experimental Breeder Reactor-II more than 30 years ago. The full-scale demonstration of the new fuel salt synthesis line for MCRE was made possible by a breakthrough in 2024. After years of testing, the team found the right recipe to convert 95 percent of uranium metal feedstock into 18 kilograms of uranium chloride fuel salt in only a few hours — a process that previously took more than a week to complete... After delivering the first batch of fuel salt this fall, the team anticipates delivering four additional batches by March of 2026. MCRE is anticipated to run in 2028 for approximately six months at INL in the Laboratory for Operation and Testing (LOTUS) in the United States test bed. "With the first batch of fuel salt successfully created at INL, researchers will now conduct testing to better understand the physics of the process, with a goal of moving the process to a commercial scale over the next decade," says Cowboy State Daily.

Can This Simple Invention Convert Waste Heat Into Electricity?
Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun.But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.] Waste heat...The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source. As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more.Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about.Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat... For Johnson, the potential application he's most excited about lies beneath our feet.Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity."You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said... On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon. "Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."
