China plans to commercialize nuclear fusion for emissions-free power generation by 2050, with its first operational project expected around 2050 after a demonstration phase starting in 2045. Bloomberg reports: China National Nuclear Corp. (CNNC) last year formed an industry alliance and set up a new national fusion company, the China Fusion Corp. It has attracted about 1.75 billion yuan ($240 million) in investment from CNNC and Zhejiang Zheneng Electric Power Co. for cutting-edge tokamak devices, which use magnetic fields to confine and control superheated plasma to produce power without emissions or significant radioactive waste. CNNC also plans to scale up production of its homegrown designs for regular nuclear fission reactors and small modular reactors over the next five years, the company's Vice General Manager Xin Feng said at the briefing.

China is set to leapfrog the US and France as the owner of the world's biggest reactor fleet by 2030. About 10 new reactors have been approved every year since power shortages emerged in 2022 and the country is expected to keep up that pace through 2030 to meet climate goals, CNNC said on Friday.

Fabled RepairTuber and right-to-repair crusader Louis Rossmann accuses Brother of implementing forced firmware updates that block third-party ink cartridges and remove older firmware versions from support portals. These updates also prevent color calibration with aftermarket ink, rendering cheaper cartridges unusable. Tom's Hardware reports: As mentioned in the intro, Rossmann has seen two big issues emerge for Brother printer users with recent firmware updates. Firstly, models that used to work with aftermarket ink, might refuse to work with the same cartridges in place post-update. Brother doesn't always warn about such updates, so Rossmann says that it is important to keep your printer offline, if possible. Moreover, he reckons it is best to keep your printers offline, and "I highly suggest that you turn off your updates," in light of these anti-consumer updates. Another anti-consumer problem Rossmann highlights affects color devices. He cites reports from a Brother MFP user who noticed color calibration didn't work with aftermarket inks post-update. They used to work, and if the update doesn't allow the printer to calibrate with this aftermarket ink the cheaper carts become basically unusable.

Making matters worse, and an aspect of this tale which seems particularly dastardly, Rossmann says that older printer firmware is usually removed from websites. This means users can't roll back when they discover the unwanted new 'features' post-update. While he admittedly can't do much about these printer industry machinations, Rossmann says it feels important to document these changes which show that property rights for individuals are disappearing. Additional info about Brother's issues are available on Rossmann's wiki.

Earth's core "burns with an estimated forty-four trillion watts of power," the New Yorker reminds us — enough to "satisfy the entire world's energy needs" with a power source that's carbon-free, ubiquitous — and unlimited. (Besides running 24 hours a day, one of geothermal energy's key advantages is "it can be used for both electricity and heating, which collectively account for around 38% of global climate emissions...")

And one drilling expert tells them there's been an "exponential spin-up of activity in geothermal" energy projects over the last two years. (Ironically it was the fracking boom also brought an "explosion of new drilling practices — such as horizontal drilling and magnetic sensing — that inspired a geothermal resurgence.") In 2005 one research team calculated that just 2% of the heat just four miles underground in America "could meet the entire country's energy needs — two thousand times over," according to the article.

So their new article checks in on the progress of geothermal energy projects around the world, including a Utah company using a diamond-bit drill to dig nearly a mile into the earth to install a 150-ton steel tube surrounded by special heat-resistant cement — all to create "a massive straw" for transporting hot water (and steam). The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons... At 6:15 P.M. on May 3rd, cement had started flowing into the hole. Four hours later, part of the cement folded in on itself. The next morning, the cement supply ran out; the men had miscalculated how much they needed. This brought the three-hundred-million-dollar operation to a maddening halt... The cement truck from Bakersfield arrived around 8:30 P.M. By ten-thirty, the men were pouring cement again, gluing the enormous metal straw in place. Next, the team scanned the borehole with gamma rays...

"Thousands of buildings across the United States are staying cool with the help of cutting-edge batteries made from one of the world's simplest materials," reports the Washington Post — ice. When electricity is cheap, the batteries freeze water. When energy costs go up, building managers turn off their pricey chillers and use the ice to keep things cool. A typical building uses about a fifth of its electricity for cooling, according to the International Energy Agency. By shifting their energy use to cheaper times of day, the biggest buildings can save hundreds of thousands of dollars a year on their power bills. They can also avoid using electricity from the dirtiest fossil fuel plants. In places where the weather is hot and energy prices swing widely throughout the day — for instance, Texas, Southern California and most of the American Southwest — buildings could cut their power bills and carbon emissions by as much as a third, experts say...

When every building is blasting its air conditioner at the same moment on a hot day, power companies often fire up backup generators, known as peaker plants, which are generally extra pricey and polluting. If utilities avoid using peaker plants, they'll pollute less and save money. Last year, the Energy Department struck a tentative $306 million loan deal with the ice-battery-maker Nostromo Energy to install its systems in 193 California buildings to make energy cheaper and cleaner while lowering the state's blackout risk.
"The batteries themselves are huge..." the article acknowledges, citing one in New York City that uses 100 parking spot-sized tanks "which collectively make 3 million margaritas' worth of ice each night... But that's starting to change." (And they believe new smaller designs "could bring the batteries into smaller buildings and even houses.") Wherever they can squeeze into the market, ice batteries could be a cheaper and longer-lasting option than the lithium-ion batteries that power phones, cars and some buildings because their main ingredient is water, experts say. The pricey chemicals in a lithium-ion cell might degrade after 10 years, but water never wears out.
And according to the article, one company has already installed ice batteries in over 4,000 buildings...

Can a new 3D-printing technique shorten 3D printing times to just seconds? A team of researchers in Europe has modified Tomographic Volumetric Additive Manufacturing, which can "create entire objects in one shot by shining light patterns into liquid resin," according to the 3D Printing Industry blog. (The liquid resin then solidifies when the light intensity is high enough...) While this approach can fabricate support-free, micro-scale parts within tens of seconds, it is "highly inefficient." This is because under 1% of the encoded light reaches the resin vial. Conventional TVAM can also lead to unwanted distortions and poor resolution due to light blurring and projection artifacts. To address these limitations, the researchers developed HoloVAM, a new technique that uses a 3D hologram instead of conventional volumetric light projections. This approach reportedly boosts light efficiency by 20 times, resulting in faster and more accurate 3D printing.

According to their paper, published in Nature Communications, HoloVAM successfully fabricated several millimeter-scale objects in under 60 seconds with fine details as small as 31 micrometers...

They believe this new approach offers value for medical bioprinting applications, thanks to HoloVAM's use of "self-healing beams." These can generate and retain their shape when passing through materials, which is particularly valuable when 3D printing with cell-laden bio-resins and hydrogels.

A German nuclear fusion startup called Proxima Fusion has unveiled its "Stellaris" fusion power plant designed to operate reliably and continuously without the instabilities of tokamaks. It's backed by $65 million in funding, with plans to build a fully operational fusion reactor by 2031. TechCrunch reports: Tokamaks and stellarators are types of fusion reactors that use electromagnets to contain fusion plasma. Tokamaks rely on external magnets and an induced plasma current but are known for instability. Stellarators, by contrast, use only external magnets, which, in theory, enable better stability and continuous operation. However, according to Dr. Francesco Sciortino, co-founder and CEO of Proxima Fusion, Proxima's "Stellaris" design is the first peer-reviewed fusion power plant concept that demonstrates it can operate reliably and continuously, without the instabilities and disruptions seen in tokamaks and other approaches.

Proxima published its findings in Fusion Engineering and Design, choosing to share this information publicly to support open-source science. "Our American friends can see it. Our Chinese friends can see it. Our claim is that we can execute on this faster than anyone else, and we do that by creating a framework for integrated physics, engineering, and economics. So we're not a science project anymore," Sciortino told TechCrunch over a call. "We started out as a group of founders saying it's going to take us two years to get to the Stellaris design ... We actually finished after one year. So we've accelerated by a year," he added.

Chinese robotics company Zhongqing Robotics (also known as Engine AI) posted a video of what is claimed to be the world's first humanoid robot front flip. New Atlas reports: Ten years ago, this kind of stuff simply did not exist. And now you can buy your very own open-source PM01 robot for US$13,700, according to EngineAI's website. Its specs aren't bad: 5-DoF (degrees of freedom) in each arm and six per leg. That's 23-DoF in body movement in total. The bot also boasts 221 lb-ft of torque (300 Nm), which seems like quite a punch when the little guy is only 4.5 ft (138 cm) tall and weighs 88 lb (40kg). You can watch the video here.

A massive blackout has hit Chile, leaving millions without power and disrupting transportation, businesses, and essential services across 14 of the country's 16 regions. The Associated Press reports: The National Electrical Coordinator, Chile's grid operator, said a disruption had occurred in a high-voltage transmission line that carries power from the Atacama Desert of northern Chile to the capital of Santiago in the country's central valley. It did not say what actually caused the disruption that pushed much of the country's power grid into shutdown, from the northernmost Chilean port of Arica to the southern Los Lagos agricultural region.

Interior Minister Carolina Toha said hospitals, prisons and government buildings were switching on backup generators to keep essential equipment operating. In a press conference, Toha urged the public to stay calm and said officials were racing to put the grid back in operation and restore electric service across the country of some 19 million people. "It's affecting the entire electrical system of the country," she said of the breakdown in the 500-kV backbone transmission line. Toha said if all areas didn't return to normal by sunset the government would take emergency measures to avert a crisis. [...]

Videos on social media from all over Chile, a long ribbon of a country stretching 4,300 kilometers (over 2,600 miles) along the southern Pacific coast, showed chaos at intersections with no functioning traffic lights, people having to use their mobile phones as torches in the underground metro and police dispatched to help evacuate office buildings.

At its "Second Gen" event today, Framework detailed three new computers: an updated Framework Laptop 13 with AMD Ryzen AI 300, a 4.5-liter Mini-ITX desktop powered by Ryzen AI Max, and a colorful, convertible Framework Laptop 12 designed with students in mind. The latter is defined by Framework as a "defining product." Tom's Hardware reports: Framework Desktop: The Framework Desktop is a 4.5L Mini-ITX machine using AMD's Ryzen AI Max "Strix Halo" chips with Radeon 8060S graphics. While this is a mobile chip, Framework says putting it in a desktop chassis gets it to 120W sustained power and 140W boost "while staying quiet and cool." Framework says this should allow 1440p gaming on intense titles, as well as workstation-class projects and local AI. [...] The base model, with a Ryzen AI Max 385 and 32GB of RAM, starts at $1,099, while the top-end machine with a Ryzen AI Max+ 395 with 128GB of RAM begins at $1,999. Framework is only doing "DIY" editions here, so you'll have to get your own storage drive and bring your own operating system (the company is calling it "the easiest PC you'll ever build"). The mainboard on its own will be available from $799. Pre-orders are open now, and Framework expects to ship sometime in Q3.

Framework Laptop 12: The Laptop 12 is designed to bring the flexibility from the Laptop 12 but make it smaller, cheaper, and in more colors (with an optional stylus to match). These machines are made of ABS plastic molded in thermoplastic polyurethane, all around a metal frame. Framework says that it's "our easiest product ever to repair," but that more information on that will come closer to its launch in mid-2025. I'm really looking forward to this repair guide. It comes in five colorways: lavender, sage, gray, black, and bubblegum. The laptop will come with 13th Gen Intel Core i3 and i5 processors, which aren't the latest, but better than entry-level junk. You'll get up to 48GB of RAM, 2TB of storage, and Wi-Fi 6E. It has a 1920 x 1200 touch screen that the company claims will surpass 400 nits of brightness. There's no pricing information yet, and Framework says there's more to share on pricing and specs later in the year. Pre-orders will open in April ahead of the mid-year launch.

Framework Laptop 13: The Framework Laptop 13 is getting a significant refresh with AMD Ryzen AI 300 Series. It doesn't look all that different on the outside, with a 13.5-inch design that largely resembles the one from way back in 2021. But there are new features. Beyond the processors, the Framework Laptop 3 is getting bumped up to Wi-Fi 7 and is getting a new thermal system, a "next-generation" keyboard, and new colorways for the Expansion Cards and bezels (though I still don't know why you would want a bezel in anything other than black). [...] The new Framework Laptop 13 with AMD Ryzen AI 300 starts at $899 for a DIY Edition without storage or an OS, and $1,099 for a pre-built model. If you're buying the mainboard to put in an old system, that's $449. (Framework is keeping the Ryzen 7040 systems around starting at $749). No word for now on any new Intel models.

An anonymous reader quotes a report from 9to5Google: Starting with the Snapdragon 8 Elite, Qualcomm will offer device manufacturers (OEMs) the "ability to provide support for up to eight consecutive years of Android software and security updates." Qualcomm today announced a "program" in partnership with Google: "What this means is that support for platform software included in this program will be made available to OEMs for eight consecutive years, including both Android OS and kernel upgrades, without requiring significant changes or upgrades to the platform and OEM code on the device (a separation commonly referred as 'Project Treble' or the 'vendor implementation'). While kernel changes will require updating kernel mode drivers, the vendor code can remain unchanged while the software support is being provided."

This program specifically includes "two upgrades to the mobile platform's Android Common Kernel (ACK) to support the eight-year window." It's ultimately up to manufacturers to update their devices, but the bottleneck going forward won't be the chip. Qualcomm today notes how the extended software support it's providing can "lower costs for OEMs interested in supporting their devices longer." The first devices to benefit are Snapdragon 8 Elite-powered smartphones launching with Android 15. Notably, the program runs for the "next five generations" of SoCs, including Snapdragon 8 and 7-series chips launching "later this year." Older chipsets will not benefit from this program.

Microsoft has updated its CPU compatibility list for Windows 11 24H2, excluding pre-11th-generation Intel processors for OEMs building new PCs. The Register reports: Windows 11 24H2 has been available to customers for months, yet Microsoft felt compelled in its February update to confirm that builders, specifically, must use Intel's 11th-generation or later silicon when building brand new PCs to run its most recent OS iteration. "These processors meet the design principles around security, reliability, and the minimum system requirements for Windows 11," Microsoft says.

Intel's 11th-generation chips arrived in 2020 and were discontinued last year. It would be surprising, if not unheard of, for OEMs to build machines with unsupported chips. Intel has already transitioned many pre-11th generation chips to "a legacy software support model," so Microsoft's decision to omit the chips from the OEM list is understandable. However, this could be seen as a creeping problem. Chips made earlier than that were present very recently, in the list of supported Intel processors for Windows 11 22H2 and 23H2.

This new OEM list may add to worries of some users looking at the general hardware compatibility specs for Windows 11 and wondering if the latest information means that even the slightly newer hardware in their org's fleet will soon no longer meet the requirements of Microsoft's flagship operating system. It's a good question, and the answer -- currently -- appears to be that those "old" CPUs are still suitable. Microsoft has a list of hardware compatibility requirements that customers can check, and they have not changed much since the outcry when they were first published.

"A line idle for decades has been accused of starting the LA area's deadly Eaton Fire," writes Bloomberg, describing California's abandoned power lines as "a fire risk hiding in plain sight." [Abandoned power lines] fall out of use, either because they've been replaced or because the power plants they once connected to the grid shut down... Sometimes the utilities that own idled lines disconnect them from the power grid, cutting off the flow of electricity through the cables. Other times, they don't, keeping them energized. California regulations require the companies to remove power lines they don't anticipate using again, but there's no set deadline. The companies can keep idled lines in place if they foresee needing them in the future, so long as they're regularly inspected and maintained.

Even those that have been unplugged from the grid can potentially pose a danger. The line under scrutiny due to the Eaton Fire is owned by Edison International's Southern California utility and was retired in 1971. Under normal circumstances, it carries no electricity, according to the company. Lawyers suing Edison allege that a January 7 power surge on a nearby, active line created a magnetic field that briefly re-energized the dormant cable, setting off the sparks that ignited the blaze. Edison said in a state filing that it is investigating that theory. State investigators have yet to announce a cause for the fire.
A 2019 fire that burned 77,700 acres (31,444 hectares) was started by an old power line for a plant that closed in 2001, according to the article. PG&E, the state's largest utility, "hadn't removed it, and it stayed connected to the grid, energized." [PG&E] agreed to remove 72 permanently abandoned transmission lines — representing about 260 miles (418 kilometers) of dormant cables. The work could cost as much as $268 million spread over 10 years, the company estimated at the time. PG&E had removed 64 of the idled lines by the end of 2024, according to a spokesman.

"At the right conditions, failing idle facilities can pose significant wildfire and safety risks," PG&E said in its plan to remove the equipment.

An anonymous reader shared this report from the Associated Press: A computerized system that calls balls and strikes is being tested during Major League Baseball spring training exhibition games starting Thursday after four years of experiments in the minor leagues. Baseball Commissioner Rob Manfred is an advocate of the Automated Ball-Strike System, which potentially as early as 2026 could be used to aid MLB home plate umpires, but not replace them...

Stadiums are outfitted with cameras that track each pitch and judge whether it crossed home plate within the strike zone. In early testing, umpires wore ear buds and would hear "ball" or "strike," then relay that to players and fans with traditional hand signals. The challenge system adds a wrinkle. During spring training, human umps will call every pitch, but each team will have the ability to challenge two calls per game, with no additions for extra innings. A team retains its challenge if successful, similar to the regulations for big league teams with video reviews, which were first used for home run calls in August 2008 and widely expanded to many calls for the 2014 season.

Only a batter, pitcher or catcher may challenge a call, signaling with the tap of a helmet or cap; and assistance from the dugout is not allowed. A challenge must be made within 2 seconds... MLB has installed the system in 13 spring training ballparks that are home to 19 teams.
After a full season of testing in the Triple-A minor league, roughly 51% of the challenges were successful. Interestingly, the system makes its call exactly halfway across home plate> , where human umpires consider the strike zone to cover the whole 17 inches from the front to the back of home plate.

New power plants burning natural gas are being built all across America, reports the Washington Post, calling it a gas boom "driven in large part by AI."

They blame tech companies like Microsoft and Meta — which "looked to gas amid a shortage of adequate new clean energy" — while noting that those companies "say they plan to offset their development of natural gas capacity with equal investments in clean energy like solar and wind." [E]ven coal is making a comeback. But the biggest push is for gas, with more than 220 plants in various stages of development nationwide. They are often pitched as a bridge until more clean power is available, sometimes with promises the plants will eventually be equipped with nascent technology that traps greenhouse gas emissions. But the timeline for installing such "carbon capture" is vague. "These companies are building these massive new gas plants that are going to be there for 30 to 50 years," said Bill Weihl, a former director of sustainability at Facebook and founder of the nonprofit ClimateVoice. "That's not a bridge. It is a giant bomb in our carbon budget...."

Public filings from some of the big tech companies driving this development show their greenhouse gas emissions are soaring... "The last few years have revealed that a global energy transition is more complex and less linear than anticipated," Microsoft's board wrote in urging rejection of a December shareholder resolution demanding the company confront the climate risks of AI. "While urgency builds for decarbonization, so does the demand for energy."

Shareholders rejected the resolution. Microsoft is battling with environmental groups over its plans to build a multibillion-dollar data center in Mount Pleasant, Wisconsin, powered with electricity from natural gas. Their petition warns Microsoft's project "will push our state's climate goals out of reach, locking us into 30 more years of fossil fuels." The company said in a statement that it remains committed to erasing its emissions by adding substantial clean power to regional power grids. "By the end of 2025 we expect to meet our goal of adding new sources of carbon-free electricity to the grid equal to 100 percent of the electricity used by our datacenters," the statement said.

Meta says it is doing the same in Louisiana [where it's building a new 4-million-square-foot data center] and is "committed to matching our electricity use with 100 percent clean and renewable energy."
The article includes two revealing quotes:

• "It is like everyone just gave up," said Aaron Zubaty, CEO of Eolian, a large clean energy developer that works with data centers.

• American Petroleum Institute President Mike Sommers (who represents the oil and gas industry in Washington), said "The words that have replaced 'energy transition' are 'AI' and 'data centers'. We're transitioning from the energy transition to the energy reality ... We're going to need a lot more oil and gas."

Remember that battery plant fire last month in Moss Landing, California? Tuesday night local firefighters "determined that a group of lithium batteries in an area that had previously burned during the January 16 fire had smoldered and reignited," reports SFGate.

Fire Chief Joel Mendoza said the flames burned at varying intensities throughout Tuesday night before the fire burned itself out at about 8 a.m. on Wednesday. Additional flare-ups at the site are expected due to weather exposure and damage to the remaining batteries. "Rekindling is very, very likely — almost a certainty," said EPA onsite coordinator Eric Sandusky, adding that rain and humidity can interact with the damaged batteries, leading to short circuits and reignition. To further reduce fire risk, Sandusky said the EPA is working with Vistra to begin "de-linking the batteries," a process that disconnects them to lower the risk of propagation and prevent a large-scale fire...
"Vistra said that since the January 16 fire, they have brought in a private fire crew that is on-site at all times to monitor the Moss 300 building," according to a local news site.

Fire Chief Joel Mendoza shared more details with the digital newspaper Lookout Santa Cruz. "We've been saying all along that batteries exposed to heat that didn't burn can ignite. We were hoping that it wouldn't happen, but it did."
