A leaked Meta video revealed upcoming "Meta Ray-Ban Display" smart glasses with a monocular HUD and sEMG wristband control, set to debut at Connect 2025 for around $800. Despite past hesitation, it looks like EssilorLuxottica has agreed to co-brand after Meta invested $3.5 billion in the company, taking a 3% stake. UploadVR reports: Meta's HUD glasses with the sEMG wristband will in fact be Ray-Ban branded, a leaked video which also depicts the HUD and wristband in action reveals. A quickly removed unlisted video on Meta's YouTube channel showed what will soon be Meta and EssilorLuxottica's full lineup:

- The regular Ray-Ban Meta glasses.
- The recently-launched Oakley Meta HSTN glasses.
- The rumored Oakley Meta Sphaera glasses, with eye protection and a centered camera.
- The rumored monocular heads-up display (HUD) glasses controlled by Meta's long-in-development sEMG wristband, which are labeled as "Meta Ray-Ban" with the word "Display" underneath. The smart glasses are expected to be made official during the Meta Connect 2025 keynote at 5pm PT on Wednesday.

Lead times for high-capacity hard drives have exceeded 52 weeks as AI workloads drive unprecedented demand for warm storage that sits between fast SSDs and offline tape archives, according to TrendForce. Western Digital notified customers of price increases across its entire hard drive portfolio citing demand for "every capacity" in its product line.

The shortage stems from AI infrastructure requirements including training datasets, model checkpoints and inference logs that consume petabytes of storage space. These files are too large for primary SSD storage but must remain accessible for quick retrieval. Hard drive manufacturers have not significantly expanded production capacity in approximately a decade. Cloud service providers are evaluating QLC SSDs for cold data storage despite costs remaining four to five times higher per gigabyte than mechanical drives. Memory suppliers are developing SSD products specifically for this intermediate storage tier.

Long-time Slashdot reader schwit1 shared this article from IEEE Spectrum: The world's largest airplane, when it's built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that's sprouted wings — aeronautical engineering at a preposterous scale.

Called WindRunner, and expected by 2030, it'll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length of 70 meters, max. This size constraint comes not from the limits of blade engineering or physics; it's transportation. Any larger and the blades couldn't be moved over land, since they wouldn't fit through tunnels or overpasses, or be able to accommodate some of the sharper curves of roads and rails.

So the WindRunner's developer, Radia of Boulder, Colorado, has staked its business model on the idea that the only way to get extralarge blades to wind farms is to fly them there... Radia's plane will be able to hold two 95-meter blades or one 105-meter blade, and land on makeshift dirt runways adjacent to wind farms. This may sound audacious — an act of hubris undertaken for its own sake. But Radia's supporters argue that WindRunner is simply the right tool for the job — the only way to make onshore wind turbines bigger. Bigger turbines, after all, can generate more energy at a lower cost per megawatt. But the question is: Will supersizing airplanes be worth the trouble...?

Having fewer total turbines means a wind farm could space them farther apart, avoiding airflow interference. The turbines would be nearly twice as tall, so they'll reach a higher, gustier part of the atmosphere. And big turbines don't need to spin as quickly, so they would make economic sense in places with average wind speeds around 5 meters per second compared with the roughly 7 m/s needed to sustain smaller units. "The result...is more than a doubling of the acres in the world where wind is viable," says Mark Lundstrom [Radia's founder and CEO].
The executive director at America's National Renewable Energy Laboratory Foundation points out that one day blades could just be 3D-printed on-site — negating the need for the airplane altogether. But 3D printing for turbines is still in its earliest stages.

"Engineers from Ohio State University are developing a new way to power rocket engines," reports Gizmodo, "using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year..." Nuclear propulsion uses a nuclear reactor to heat a liquid propellant to extremely high temperatures, turning it into a gas that's expelled through a nozzle and used to generate thrust. The newly developed engine concept, called the centrifugal nuclear thermal rocket (CNTR), uses liquid uranium to heat rocket propellant directly. In doing so, the engine promises more efficiency than traditional chemical rockets, as well as other nuclear propulsion engines, according to new research published in Acta Astronautica...

Traditional chemical engines produce about 450 seconds of thrust from a given amount of propellant, a measure known as specific impulse. Nuclear propulsion engines can reach around 900 seconds, with the CNTR possibly pushing that number even higher. "You could have a safe one-way trip to Mars in six months, for example, as opposed to doing the same mission in a year," Spencer Christian, a PhD student at Ohio State and leader of CNTR's prototype construction, said in a statement.

CNTR promises faster routes, but it could also use different types of propellant, like ammonia, methane, hydrazine, or propane, that can be found in asteroids or other objects in space.
"Some potential hurdles include ensuring that the methods used for startup, operation and shutdown avoid instabilities," according to the researchers' announcement, as well as "envisioning ways to minimize the loss of uranium fuel and accommodate potential engine failures."

But "This team's CNTR concept is expected to reach design readiness within the next five years..."

RestOfWorld.org reports on "a global crisis nobody anticipated when governments started subsidizing electric vehicles..."

"EVs can lose almost half their driving distance when temperatures drop, and the billions spent on improving technology have failed to fix this fundamental limitation." In January, Seattle-based Recurrent, a company that tests and analyzes EVs, found an average range loss of 20% in extreme cold... Lithium-ion batteries rely on chemical reactions that slow dramatically in cold weather. When temperatures plunge, the electrolyte thickens, ions move sluggishly, and charging becomes not just inefficient but potentially dangerous. Charging in cold weather has been identified as a primary cause of thermal acceleration, which can lead to fires...

The failure pattern repeats globally wherever cold weather meets inadequate infrastructure. Manufacturers, too, have acknowledged the problem. Chinese EV maker BYD's user manual, for instance, advises drivers to charge indoors, with the heating on. That advice is useless for farmers parking in open courtyards.
In fact, research across 293 Chinese cities "found that many drivers in colder regions buy EVs only as supplementary vehicles," according to the article, "while still relying on gasoline-powered cars during winter."

The article also tells the story of an apple grower chilly Kashmir, India who discovered that his Chinese three-wheeler lost 60% of its 10-hour charge overnight. This made it impossible to begin the 56-kilometer (35-mile) trip on a route with no charging stations — and prevented him from selling his produce while it was fresh (to earn the highest prices). And the problem affects the entire region: Desperate drivers have formed WhatsApp groups, such as "EV Apple Transporters" and "Battery Help Kashmir," sharing increasingly absurd workarounds. Some have wrapped batteries in quilts; others have hauled power packs weighing 90 kilograms (over 200 pounds) into their homes for the night. One driver parked his battery in the living room. "The blankets caused overheating on the road; water bottles leaked into the circuits," [orchard owner] Sajad Ahmad said. "We became mechanics, engineers, and fools all at once." EVs are also not considered cost-efficient. "Diesel vans are expensive, but they can do four or five trips a day," Mohammad Yaseen, a driver based in Shopian, told Rest of World. "With EVs, one half-trip and you're stuck."

Norway, where winter temperatures average minus 7 degrees Celsius (19 degrees Fahrenheit), achieved 89% EV market share with its comprehensive infrastructure. It offers more than 200 models for year-round usage. "The ability to preheat batteries upon fast charging in winter is by far the most important improvement we have seen in the past five years," Christina Bu, secretary-general of the Norwegian EV Association, told Rest of World.
"These features are standard in Norway's mature market, but remain absent from basic models exported to developing countries."

"There has never been a successful, widespread malware attack against iPhone," notes Apple's security blog, pointing out that "The only system-level iOS attacks we observe in the wild come from mercenary spyware... historically associated with state actors and [using] exploit chains that cost millions of dollars..."

But they're doing something about it — this week announcing a new always-on memory-safety protection in the iPhone 17 lineup and iPhone Air (including the kernel and over 70 userland processes)... Known mercenary spyware chains used against iOS share a common denominator with those targeting Windows and Android: they exploit memory safety vulnerabilities, which are interchangeable, powerful, and exist throughout the industry... For Apple, improving memory safety is a broad effort that includes developing with safe languages and deploying mitigations at scale...

Our analysis found that, when employed as a real-time defensive measure, the original Arm Memory Tagging Extension (MTE) release exhibited weaknesses that were unacceptable to us, and we worked with Arm to address these shortcomings in the new Enhanced Memory Tagging Extension (EMTE) specification, released in 2022. More importantly, our analysis showed that while EMTE had great potential as specified, a rigorous implementation with deep hardware and operating system support could be a breakthrough that produces an extraordinary new security mechanism.... Ultimately, we determined that to deliver truly best-in-class memory safety, we would carry out a massive engineering effort spanning all of Apple — including updates to Apple silicon, our operating systems, and our software frameworks. This effort, together with our highly successful secure memory allocator work, would transform MTE from a helpful debugging tool into a groundbreaking new security feature.

Today we're introducing the culmination of this effort: Memory Integrity Enforcement (MIE), our comprehensive memory safety defense for Apple platforms. Memory Integrity Enforcement is built on the robust foundation provided by our secure memory allocators, coupled with Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and supported by extensive Tag Confidentiality Enforcement policies. MIE is built right into Apple hardware and software in all models of iPhone 17 and iPhone Air and offers unparalleled, always-on memory safety protection for our key attack surfaces including the kernel, while maintaining the power and performance that users expect. In addition, we're making EMTE available to all Apple developers in Xcode as part of the new Enhanced Security feature that we released earlier this year during WWDC...

Based on our evaluations pitting Memory Integrity Enforcement against exceptionally sophisticated mercenary spyware attacks from the last three years, we believe MIE will make exploit chains significantly more expensive and difficult to develop and maintain, disrupt many of the most effective exploitation techniques from the last 25 years, and completely redefine the landscape of memory safety for Apple products. Because of how dramatically it reduces an attacker's ability to exploit memory corruption vulnerabilities on our devices, we believe Memory Integrity Enforcement represents the most significant upgrade to memory safety in the history of consumer operating systems.

Wind and solar power generated more than a third of Brazil's electricity in August, the first month on record the two renewable sources have crossed that threshold, according to government data made public on Thursday and analyzed by energy think tank Ember. AP: The clean energy sources accounted for 34% of the country's electricity generation last month, producing a monthly record of 19 terawatt-hours (TWh), enough to power about 119 million average Brazilian homes for a month, Ember told The Associated Press.

That surpassed the previous high of 18.6 TWh set in September 2024. The milestone came as hydroelectric output, Brazil's dominant power source, fell to a four-year low. "Brazil shows how a rapidly growing economy can meet its rising need for electricity with solar and wind," said Raul Miranda, Ember's global program director based in Rio de Janeiro.

Researchers in China have developed a "DNA cassette," a retro-styled plastic tape embedded with synthetic DNA strands that can store up to 36 petabytes of digital data -- enough to hold every song ever recorded. New Scientist reports: Xingyu Jiang at the Southern University of Science and Technology in Guangdong, China, and his colleagues created the cassette by printing synthetic DNA molecules on to a plastic tape. "We can design its sequence so that the order of the DNA bases (A, T, C, G) represents digital information, just like 0s and 1s in a computer," he says. This means it can store any type of digital file, whether text, image, audio or video.

One problem with previous DNA storage techniques is the difficulty in accessing data, so the team then overlaid a series of barcodes on the tape to assist with retrieval. "This process is like finding a book in the library," says Jiang. "We first need to find the shelf corresponding to the book, then find the book on the corresponding shelf."

The tape is also coated in what the researchers describe as "crystal armor" made of zeolitic imidazolate, which prevents the DNA bonds from breaking down. That means the cassette could store data for centuries without deteriorating. While a traditional cassette tape could boast around 12 songs on each side, 100 meters of the new DNA cassette tape can hold more than 3 billion pieces of music, at 10 megabytes a song. The total data storage capacity is 36 petabytes of data -- equivalent to 36,000 terabyte hard drives. The research has been published in the journal Science Advances.

Apple's new Watch lineup introduces blood pressure monitoring, sleep scoring, and upgraded hardware across the Series 11 ($399), Ultra 3 ($799), and SE 3 ($249). Ars Technica reports: The Apple Watch 11 is supposed to be able to alert users about "possible hypertension" by using data from an optical heart rate sensor "to analyze how a user's blood vessels respond to the beats of the heart," per its announcement. According to Apple's presentation, the smartwatch will look for chronic hypertension over 30-day periods. Apple's presentation noted that the Watch Series 11 won't be able to identify all hypertension, but the company said that it expects to notify over 1 million people with undiagnosed hypertension during the feature's first year of availability. The feature is based on machine-learning and training data built from multiple studies examining over 100,000 people combined, Apple noted. Apple said it expects the blood pressure monitoring feature to receive Food and Drug Administration clearance soon and to get approval in 150 regions this month.

The new watch will use a 5G modem and also introduce a feature that provides wearers with a "sleep score" that's based on the duration of their sleep, the consistency of their bedtime, how often they awaken from their sleep, and how much time they spend in each sleep stage. The Watch will analyze those factors every night and then provide a breakdown of how each score is calculated. The feature is based on an algorithm tested with 5 million nights of sleep data, Apple said. Other updates include the use of INX glass with ceramic coating that's supposed to make the Watch Series 11 two times more scratch-resistant than its predecessor. The Apple Watch Ultra 3 also debuted with hypertension notifications and sleep scoring, but comes equipped with a brighter edge-viewable OLED display, stronger radios with 5G and satellite support, and a larger 42-hour battery. It starts at $799.

Meanwhile, the budget-friendly SE 3 adds the new S10 chip with always-on display, faster charging, and expanded health tracking -- including sleep scores, apnea alerts, and temperature monitoring. It starts at $249.

Apple has unveiled the AirPods Pro 3 with heart-rate sensing, improved noise cancellation, a more compact case, and upcoming live translation features powered by Apple Intelligence. They'll be available for preorder today at a price of $249. TechCrunch reports: One of the standout features of the AirPods Pro 3 is its heart-rate sensing capability, a first for the AirPods line. This addition will operate similarly to the Powerbeats Pro 2, using LED sensors to provide precise measurements. The collected data will sync with Apple's Fitness app. The active noise cancellation, which reduces external noise, has been significantly improved. Apple says it removes twice the noise compared to Pro 2.

A noteworthy upcoming feature is a live translation capability, thanks to Apple's iOS 26 software update. This lets you have conversations in different languages, using your iPhone to translate while the phone plays one language and the AirPods handle the other. Other notable updates include smaller, more comfortable earbuds. Apple now offers foam ear tips in five different sizes, and the company claims it's "the best-fitting AirPods."

Four years ago a small Microsoft Research team started creating an analog optical computer. They used commercially available parts like sensors from smartphone cameras, optical lenses, and micro-LED lights finer than a human hair. "As the light passes through the sensor at different intensities, the analog optical computer can add and multiply numbers," explains a Microsoft blog post.

They envision the technology scaling to a computer that for certain problems is 100X faster and 100X more energy efficient — running AI workloads "with a fraction of the energy needed and at much greater speed than the GPUs running today's large language models." The results are described in a paper published in the scientific journal Nature, according to the blog post: At the same time, Microsoft is publicly sharing its "optimization solver" algorithm and the "digital twin" it developed so that researchers from other organizations can investigate this new computing paradigm and propose new problems to solve and new ways to solve them. Francesca Parmigiani, a Microsoft principal research manager who leads the team developing the AOC, explained that the digital twin is a computer-based model that mimics how the real analog optical computer [or "AOC"] behaves; it simulates the same inputs, processes and outputs, but in a digital environment — like a software version of the hardware. This allowed the Microsoft researchers and collaborators to solve optimization problems at a scale that would be useful in real situations. This digital twin will also allow other users to experiment with how problems, either in optimization or in AI, would be mapped and run on the analog optical computer hardware. "To have the kind of success we are dreaming about, we need other researchers to be experimenting and thinking about how this hardware can be used," Parmigiani said.

Hitesh Ballani, who directs research on future AI infrastructure at the Microsoft Research lab in Cambridge, U.K. said he believes the AOC could be a game changer. "We have actually delivered on the hard promise that it can make a big difference in two real-world problems in two domains, banking and healthcare," he said. Further, "we opened up a whole new application domain by showing that exactly the same hardware could serve AI models, too." In the healthcare example described in the Nature paper, the researchers used the digital twin to reconstruct MRI scans with a good degree of accuracy. The research indicates that the device could theoretically cut the time it takes to do those scans from 30 minutes to five. In the banking example, the AOC succeeded in resolving a complex optimization test case with a high degree of accuracy...

As researchers refine the AOC, adding more and more micro-LEDs, it could eventually have millions or even more than a billion weights. At the same time, it should get smaller and smaller as parts are miniaturized, researchers say.

At CES in January, Nvidia's CEO Jensen Huang "stood flanked by 14 humanoid robots from different companies," remembers the Washington Post. But how close are we to real-world robot deployments?

Agility Robotics "says its factory is designed to eventually manufacture 10,000 robots a year," the Post adds (with "some" of its robots "already at work in e-commerce warehouses and auto parts factories.") Amazon even invested $150 million in the 10-year-old company (spun out from Oregon State University's robotics lab) in 2022, according to the article, "and has tested the company's robots in its warehouses." The e-commerce revolution has spawned sprawling warehouses across the country where products must be organized and customer orders assembled and shipped, but some human workers have said the repetitive work is low paid and leaves them prone to injury. Agility rents out its robots to warehouse owners it says have struggled to keep their human jobs filled, including logistics company GXO, which uses them at a warehouse for Spanx shapewear in Flowery Branch, Georgia, northeast of Atlanta. The robots pick up baskets of clothing from wheeled robots and walk them over to conveyor belts that take them to other parts of the facility.

Agility Chief Business Officer Daniel Diez said facilities like this represent a first step for humanoid robots into gainful employment. "This work gets paid, and we have eyes on large-scale deployments just doing this, and that's what we're focused on," he said. German auto parts company Schaeffler uses Agility robots to load and unload equipment at a factory in Cheraw, South Carolina. Auto part plants have become a favored proving ground for humanoid robots, with Boston Dynamics, the company famous for its videos of back-flipping robots, doing tests with its majority owner, Hyundai.
But meanwhile, RoboForce makes a robot that has two arms on a base with four wheels, the article notes, "providing stability and making it possible to lift more weight than a bipedal robot." Humanoid designs make sense "if it is so important to justify the trade-off and sacrifice of other things," RoboForce CEO Leo Ma tells the Post. "Other than that, there is a great invention called wheels."

Still, the article argues there's "a new drive to make humanoid robots practical," fueled by "the surge of investment in AI" combined with advancements in robotics that "make humanoid designs more capable and affordable." Years of steady progress have made legged robots better at balancing and stepping through tricky terrain. Improved batteries allow them to operate for longer without trailing industrial power cords. AI developers are adapting the innovations behind services like ChatGPT to help humanoids act more independently... The progress has triggered a frenzy of investment in humanoid robots and made them into a mascot for the idea that AI will soon reorder the world on the scale tech leaders have promised... Venture capitalists have invested over $5 billion in humanoid robotics start-ups since the beginning of 2024, according to financial data firm Pitchbook, and the largest tech corporations are also placing bets... Meta is working on integrating its own AI technology with humanoid robots, and Google researchers are collaborating with Austin-based humanoid robot start-up Apptronik... A host of humanoid robot companies has spawned in China, the world leader in complex manufacturing, where the government is subsidizing the industry. Six of the 14 robots that shared the stage with Nvidia's Huang were made by Chinese companies; five were American.

This week Finland inaugurated the world's largest sand battery, according to the Independent, "capable of storing vast amounts of energy generated from renewable sources like solar and wind."

The battery "will enable residents to eliminate oil from their district heating network, thereby cutting emissions by nearly 70%," notes EuroNews: Euronews Green previously spoke to the young Finnish founders, Tommi Eronen and Markku Ylönen, who engineered the technology... Lithium batteries work well for specific applications, explains Markku, but aside from their environmental issues and expense, they cannot take in a huge amount of energy. Grains of sand, it turns out, are surprisingly roomy when it comes to energy storage... The sand can store heat at around 500C for several days to even months, providing a valuable store of cheaper energy during the winter... The battery's thermal energy storage capacity equates to almost one month's heat demand in summer and a one-week demand in winter in Pornainen, Polar Night Energy says...

Polar Night Energy has big ambitions to take its technology worldwide, and is currently in "active discussions" with both Finnish and international partners.
This project (in the Finnish city of Pornainen) "is really important for us because now we can show that this really works," a spokesperson for Polar Night told Clean Technica: The profitability of the sand battery is based on charging it according to electricity prices and Fingrid's reserve markets. Its large storage capacity enables balancing the electricity grid and optimizing consumption over several days or even weeks... "The Pornainen plant can be adjusted quickly and precisely," explained Jukka-Pekka Salmenkaita, vice president of AI and special projects at Elisa Industriq, "and it also has a remarkably long energy buffer, making it well suited for reserve market optimization. Our AI solution automatically identifies the best times to charge and discharge the Sand Battery and allocates flexibility capacity to the reserve products that need it most. Continuous optimization makes it a genuinely profitable investment."

BMW unveiled its new iX3 — with nearly 500 miles of rangeand ultra-fast charging. The EV news site Electrek reports: To maximize range, BMW gave it a clean, aerodynamic design with very few lines... The BMW iX3 offers an impressive WLTP range of up to nearly 500 miles (800 km). On the EPA scale, it's expected to deliver around 400 miles of range.

Based on an 800V architecture, the BMW iX3 can deliver charging speeds of up to 400 kW. According to BMW, that means it can add over 230 miles (370 km) in just 10 minutes.
It's also BMW's first EV with bidirectional charging, according to the article.

But MotorTrend calls it "BMW's Biggest Reinvention Since the '60s." The decision to move forward in every aspect — design, architecture, technology, software, and manufacturing — was made five years ago... The new Neue Klasse architecture will start out with EVs only, but aspects of this new vision will be adopted by 40 vehicles — SUVs, sedans, coupes, maybe even a supercar — with an assortment of powertrains by the end of 2027. In other words, Neue Klasse will touch and influence everything BMW does going forward... The design philosophy for the Neue Klasse vehicles is that they should look like they skipped an entire generation.
From BMW's announcement for the iX3: Physical controls are on hand, including for the windscreen wipers, turn signal indicators, exterior mirrors, volume control, gear selector, parking brake, hazard warning lights, rear window heating and defrost function. Other functions have been optimised for use by touch and voice command or via the multifunction steering wheel... [MotorTrends notes "you must use the screen to adjust the air vents."]

The BMW Panoramic Vision projects information across the full width of the windscreen, from A-pillar to A-pillar. The content in the centre and on the front passenger side can be adapted to personal tastes and requirements. Key driving information appears in the driver's field of vision. And above the BMW Panoramic Vision, the BMW 3D Head-Up Display (if specified) can now also show integrated navigation and automated driving displays on the road with spatial depth. The free-cut-design Central Display with matrix backlight technology is located in an ergonomically ideal position next to the steering wheel. On the driver's side, vertically arranged widgets enable fast and direct access to particularly frequently used functions using QuickSelect tech. The new multifunction steering wheel serves as the primary physical control point. Its button panels help the driver and vehicle to work together symbiotically using illuminations, a relief-like surface and haptic feedback.
Some details from MotorTrends: There's an avatar for the intelligent personal assistant, activated by saying, "Hey, BMW." The BMW roundel morphs into a blue circle with big, expressive eyes and eyebrows. It looks like an amiable alien that turns to face the person addressing it, and it's programmed to wink, blush, and more, as well as to not stare too long at anyone. The assistant is quick to respond, using Alexa tech and a male or female voice to provide directions, answer questions, and perform functions.
MotorTrends adds that the iX3 "is BMW's first software-defined vehicle, meaning it can use over-the-air updates to fix problems and add features and functions, keeping it fresh over its lifetime with software that BMW developed itself."

BMW's announcement also notes "the latest systems for automated driving optimise symbiotic human-vehicle interaction..." Whenever the driver wants to accelerate, brake or steer, their inputs merge seamlessly and intuitively with AI-enabled software... The functionality offered by the City Assistant includes traffic light detection, where the car automatically stops and then moves off again.

"A U.S.-based nuclear fusion developer wants to deploy a reactor in Japan in the late 2030s or early 2040s," reports Bloomberg, "in line with the Asian country's broader plans to adopt the potent, low-carbon energy source." Commonwealth Fusion Systems, which last week announced it raised $863 million from investors including Nvidia, has been in dialogue with Japanese government officials on the use of its technology, CEO Bob Mumgaard said in an interview in Tokyo on Wednesday... Several countries are eyeing the technology for its climate and energy security benefits but only some, like China, the U.S., Russia and South Korea have managed to crack the basics. Japan revised its national strategy in June to support fusion deployment and build a demonstration plant in the 2030s.
The article notes that Commonwealth "does not currently have any reactors in operation" — but that Mitsubishi this week invested in the company, in collaboration with a consortium of 12 Japanese companies. From Mitsubishi's announcement: The Japanese Consortium will acquire technical and commercial expertise in policy, regulatory, and the development, construction, operation, and maintenance of ARC [power plant] from CFS's commercialization projects in the United States. In addition, each consortium company will bring together its know-how and expertise and aspire to expedite the commercialization and industrialization of fusion energy power generation in Japan.
