US Backs Three Mile Island Nuclear Restart With $1 Billion Loan To Constellation
An anonymous reader quotes a report from CNBC: The Trump administration will provide Constellation Energy with a $1 billion loan to restart the Crane Clean Energy Center nuclear plant in Pennsylvania, Department of Energy officials said Tuesday. Previously known as Three Mile Island Unit 1, the plant is expected to start generating power again in 2027. Constellation unveiled plans to rename and restart the reactor in Sept. 2024 through a power purchase agreement with Microsoft to support the tech company's data center demand in the region. Three Mile Island Unit 1 ceased operations in 2019, one of a dozen reactors that closed in recent years as nuclear struggled to compete against cheap natural gas. It sits on the same site as Three Mile Island Unit 2, the reactor that partially melted down in 1979 in the worst nuclear accident in U.S. history. The loan would cover the majority to the project's estimated cost of $1.6 billion. The first advance to Constellation is expected in the first quarter of 2026, said Greg Beard, senior advisor to the Energy Department's Loan Programs Office, in a call with reporters. The loan comes with a guarantee from Constellation that it will protect taxpayer money, Beard said.

Report Claims That Apple Has Yet Again Put the Mac Pro 'On the Back Burner'
An anonymous reader quotes a report from Ars Technica: Apple's Power Mac and Mac Pro towers used to be the company's primary workstations, but it has been years since they were updated with the same regularity as the MacBook Air or MacBook Pro. The Mac Pro has seen just four hardware updates in the last 15 years, and that's counting a 2012 refresh that was mostly identical to the 2010 version. Long-suffering Mac Pro buyers may have taken heart when Apple finally added an M2 Ultra processor to the tower in mid-2023, making it one of the very last Macs to switch from Intel to Apple Silicon -- surely this would mean that the computer would at least be updated once every year or two, like the Mac Studio has been? But Bloomberg's Mark Gurman says that Mac Pro buyers shouldn't get their hopes up for new hardware in 2026. Gurman says that the tower is "on the back burner" at Apple and that the company is "focused on a new Mac Studio" for the next-generation M5 Ultra chip that is in the works. As we reported earlier this year, Apple doesn't have plans to design or release an M4 Ultra, and the Mac Studio refresh from this spring included an M3 Ultra alongside the M4 Max. Note that Gurman carefully stops short of saying we definitely won't see a Mac Pro update next year -- the emphasis on the Mac Studio merely "suggests the Mac Pro won't be updated in 2026 in a significant way," and internal sources tell him "Apple has largely written off the Mac Pro." The current Mac Pro does still use the M2 Ultra rather than the M3 Ultra, which indicates that Apple doesn't see the need to update its high-end desktop every time it releases a suitable chip. But all of Apple's other desktops -- the iMac, the Mac mini, and the Studio -- have skipped a silicon generation once since the M1 came out in 2020.

Valar Atomics Says It's the First Nuclear Startup To Achieve Criticality
An anonymous reader quotes a report from Wired: Startup Valar Atomics said on Monday that it achieved criticality -- an essential nuclear milestone -- with the help of one of the country's top nuclear laboratories. The El Segundo, California-based startup, which last week announced it had secured a $130 million funding round with backing from Palmer Luckey and Palantir CTO Shyam Sankar, claims that it is the first nuclear startup to create a critical fission reaction. It's also, more specifically, the first company in a special Department of Energy pilot program aiming to get at least three startups to criticality by July 4 of next year to announce it had achieved this reaction. The pilot program, which was formed following an executive order President Donald Trump signed in May, has upended US regulation of nuclear startups, allowing companies to reach new milestones like criticality at a rapid pace. There's a difference between the type of criticality Valar reached this week -- what's known as cold criticality or zero-power criticality -- and what's needed to actually create nuclear power. Nuclear reactors use heat to create power, but in cold criticality, which is used to test a reactor's design and physics, the reaction isn't strong enough to create enough heat to make power. The reactor that reached criticality this week is not actually Valar's own model, but rather a blend of the startup's fuel and technology with key structural components provided by the Los Alamos National Laboratory, one of the DOE's research and development laboratories. The combination reactor builds off a separate fuel test performed last year at the laboratory, using fuel similar to what Valar's reactor will use. "Zero power criticality is a reactor's first heartbeat, proof the physics holds," Valar founder Isaiah Taylor said in a statement. "This moment marks the dawn of a new era in American nuclear engineering, one defined by speed, scale, and private-sector execution with closer federal partnership."

Electric Vehicle Sales Are Booming In South America
Chinese automakers are rapidly expanding across South America, boosted by the new Chinese-built Port of Chancay, aggressive pricing, local partnerships, and growing regional demand. Reuters reports: China has been ramping up sales since the opening last year of the Port of Chancay, north of Lima. The Chinese-built megaport has halved trans-Pacific shipping times just as Chinese manufacturers face rising barriers to entry in the United States and greater trade restrictions in Europe. BYD, which makes EVs, plug-in hybrids and combustion engine cars, plans to open a fourth dealership in Lima by the end of this year, while Chery and Geely have more than a dozen in total in Peru. Chinese carmakers face a profit-destroying price war at home and a growing surplus of new cars rolling out of Chinese factory lines. Much of this excess is being shipped overseas to the Middle East, Central Asia and Latin America, according to global automotive analyst Felipe Munoz at JATO Dynamics. The Chinese have "carved out space," across both electric and petrol-powered cars, said Martin Bresciani, president of Chile's automotive business chamber, CAVEM. "The Chinese have already demonstrated that they match global standards in quality." Chinese brands reached 29.6% of all new passenger car sales in Chile in the first quarter of this year. [...] Part of China's success has been partnering with trusted local importers to offer more affordable models tailored to regional tastes, according to seven dealerships Reuters spoke to in Peru, Chile, Uruguay and Argentina.

Some Americans Are Trying to Heat Their Homes With Bitcoin Mining
An anonymous reader shared this report from CNBC:[T]he computing power of crypto mining generates a lot ofheat, most which just ends up vented into the air. According todigital assets brokerage, K33, the bitcoin mining industry generates about 100 TWh of heat annually — enough to heat all ofFinland.This energy waste within a very energy-intenseindustry is leading entrepreneurs to look for ways to repurposethe heat for homes, offices, or other locations, especially in colderweather months. During a frigid snap earlier this year, TheNew York Times reviewed HeatTrio, a $900 space heater that alsodoubles as a bitcoin mining rig. Others use the heat from their ownin-home cryptocurrency mining to spread warmth throughout theirhouse. "I've seen bitcoin rigs running quietly in attics, withthe heat they generate rerouted through the home's ventilationsystem to offset heating costs. It's a clever use of what wouldotherwise be wasted energy," said Jill Ford, CEO of BitfordDigital, a sustainable bitcoin mining company based in Dallas..."Same price as heating the house, but the perk is that you aremining bitcoin," Ford said... The crypto-heated future may be unfolding in the town of Challis,Idaho, where Cade Peterson's company, Softwarm, is repurposingbitcoin heat to ward off the winter. Several shops and businesses intown are experimenting with Softwarm's rigs to mine and heat. At TCCar, Truck and RV Wash, Peterson says, the owner was spending $25 aday to heat his wash bays to melt snow and warm up the water."Traditional heaters would consume energy with no returns. Theyinstalled bitcoin miners and it produces more money in bitcoin thanit costs to run," Peterson said. Meanwhile, an industrial concretecompany is offsetting its $1,000 a month bill to heat its2,500-gallon water tank by heating it with bitcoin. Peterson hasheated his own home for two-and-a-half years using bitcoin miningequipment and believes that heat will power almost everything in thefuture. "You will go to Home Depot in a few years and buy a waterheater with a data port on it and your water will be heated withbitcoin," Peterson said. Derek Mohr, clinical associate professor at the University ofRochester Simon School of Business, remains skeptical.Bitcoin mining is so specialized now that a home computer, or evennetwork of home computers, would have almost zero chance of beinghelpful in mining a block of bitcoin, according to Mohr, with miningfarms use of specialized chips that are created to mine bitcoin muchfaster than a home computer... "The bitcoin heat devices I haveseen appear to be simple space heaters that use your own electricityto heat the room..." CNBC also spoke to Andrew Sobko, founder of Argentum AI (which isbuilding a marketplace for sharing computing power), who says theidea makes the most sense in larger settings. "We're workingwith partners who are already redirecting compute heat into buildingheating systems and even agricultural greenhouse warming. That'swhere the economics and environmental benefits make real sense.Instead of trying to move the heat physically, you move the computecloser to where that heat provides value."

Are Data Centers Raising America's Electricity Prices?
Residential utility bills in America "rose 6% on average nationwide in August compared with the same period in the previous year," reports CNBC, citing statistics from the U.S. Energy Information Administration:The reasons for price increases are often complex and vary by region. But in at least three states with high concentrations of data centers, electric bills climbed much faster than the national average during that period. Prices, for example, surged by 13% in Virginia, 16% in Illinois and 12% in Ohio. The tech companies and AI labs are building data centers that consume a gigawatt or more of electricity in some cases, equivalent to more than 800,000 homes, the size of a city essentially... "The techlash is real," said Abraham Silverman, who served as general counsel for New Jersey's public utility board from 2019 until 2023 under outgoing Democratic Gov. Phil Murphy. "Data centers aren't always great neighbors," said Silverman, now a researcher at Johns Hopkins University. "They tend to be loud, they can be dirty and there's a number of communities, particularly in places with really high concentrations of data centers, that just don't want more data centers..." [C]apacity prices get passed down to consumers in their utility bills, Silverman said. The data center load in PJM [America's largest grid, serving 13 states] is also impacting prices in states that are not industry leaders such as New Jersey, where prices jumped about 20% year over year... There are other reasons for rising electricity prices, Silverman said. The aging electric grid needs upgrades at a time of broad inflation and the cost of building new transmission lines has gone up by double digits, he said. The utilities also point to rising demand from the expansion of domestic manufacturing and the broader electrification of the economy, such as electric vehicles and the adoption of electric heat pumps in some regions... In other states, however, the relationship between rising electricity prices and data centers is less clear. Texas, for example, is second only to Virginia with more than 400 data centers. But prices in the Lone Star state increased about 4% year over year in August, lower than the national average. Texas operates its own grid, ERCOT, with a relatively fast process that can connect new electric supply to the grid in around three years, according to a February 2024 report from the Brattle Group. California, meanwhile, has the third most data centers in the nation and the second highest residential electricity prices, nearly 80% above the national average. But prices in the Golden State increased about 1% in August 2024 over the prior year period, far below the average hike nationwide. One of the reasons California's electricity rates are so much higher than most of the country is the costs associated with preventing wildfires.

Solar and Wind are Covering All New Power Demand in 2025
An anonymous reader shared this report from Electrek:Solar and wind are growing fast enough to meet all new electricity demand worldwide for the first three quarters of 2025, according to new data from energy think tank Ember. The group now expects fossil power to stay flat for the full year, marking the first time since the pandemic that fossil generation won't increase. Solar and wind aren't just expanding; they're outpacing global electricity demand itself. Solar generation jumped 498 TWh (+31%) compared to the same period last year, already topping all the solar power produced in 2024. Wind added another 137 TWh (+7.6%). Together, they supplied 635 TWh of new clean electricity, beating out the 603 TWh rise in global demand (+2.7%). That lifted solar and wind to 17.6% of global electricity in the first three quarters of the year, up from 15.2% year-over-year. That brought the total share of renewables in global electricity -solar, wind, hydro, bioenergy, and geothermal — to 43%. Fossil fuels slid to 57.1%, down from 58.7%. For the first time in 2025, renewables collectively generated more electricity than coal. And fossil generation as a whole has stalled. Fossil output slipped slightly by 0.1% (-17 TWh) through the end of Q3. Ember expects no fossil-fuel growth for the full year, driven by clean power growth outpacing demand.

EV Sales Are Still Rising. They Have Not Slumped
"Media headlines suggesting some slowdown in EV sales are simply incorrect," writes the site Electrek, "and leave out the bigger picture that gas car sales actually are dropping..."Over the course ofthe last two years or so, sales of battery electric vehicles, whilecontinuing to grow, have posted lower year-over-year percentagegrowth rates than they had in years prior. EV sales used to grow at50%+ per year, but for the last couple years, they have grown closerto ~25% per year. This alone is not particularly remarkable — itis inevitable that any growing product or category will show slowerpercentage growth rates as sales rise, particularly one that has beengrowing at such a fast rate for so long. In some recent years, wehad even seen year-over-yeardoublings in EV market share (though one of those was 2020->2021,which was anomalous). To expect improvement at that level perpetuallywould be close to impossible — after 3 years of doublingmarket share from 2023's 18% number, EVs would account for morethan 100% of the global automotive market, which cannot happen... We have seen a global EV sales growth rate of 23% in the first 10months of this year, according to a report just released by RhoMotion (recently acquired by Benchmark Mineral Intelligence). Thatincludes a +32% bump in Europe, +22% bump in China, +4% in NorthAmerica, and a big +48% bump in the "rest of the world." Notably,this 23% global growth rate is higher than last year's YTD growthrate, which was 22%at this time... In covering these trends, some journalists have attempted to usethe less-wrong phrase "slower growth," showing that EV sales arestill growing, but at a lower percentage change than previously seen. But for the first ten months of this year, that isn't true — EVsales are up more in 2025 than in 2024 by a percentage basis. Theyare also up in raw sales numbers — in 2024, EVsales grew by a larger number than in 2023. And the same is trueso far in 2025. Going back to 2023, 10.7 million EVs were soldglobally in the first 10 months. Then in 2024, 13.3 million weresold, a difference of 2.6 million. And so far in 2025, 16.5 millionEVs have sold, a difference of 3.2 million. Not only are the numbersgetting bigger, but the growth in unit sales is getting bigger aswell. Even in America, theEV market "has increased so far this year, with 11.7%US EV sales growth YTD."In terms of US hybrid sales, much has been made of customers"shifting from EVs to hybrids," which is also not the case.Conventional gas-hybrid sales areindeed up and plug-in hybrids, which have grown more slowlythan gas-hybrids/BEVs, have also shown some growth lately. Butgas-hybrid sales have not come at the cost of EV sales, rather at thecost of gas-only car sales. Because that'sjust the thing: the number of gas-only vehiclesbeing sold worldwide is a number that actually is falling.That number continues to go down year over year. Sales of newgas-powered cars are down by abouta quarter from their peak in 2017, and show no signs ofrecovering... And yet, somehow, virtually every headline you read isabout the "EV sales slump," rather than the "gas-car salesslump." The one you keep hearing about isn't happening,but the one you rarely hear about is happening... No matterwhat region of the world you're in, EV sales were up in the first10 months of this year.

Why Solarpunk Is Already Happening In Africa
Long-time Slashdot reader schwit1 shares a Substack post by economist/entrepreneur Skander Garroum:You know that feeling when you're waiting for the cable guy, and they said 'between 8am and 6pm, and you waste your entire day, and they never show up? Now imagine that, except the cable guy is 'electricity,' the day is '50 years,' and you're one of 600 million people. At some point, you stop waiting and figure it out yourself. What's happening across Sub-Saharan Africa right now is the most ambitious infrastructure project in human history, except it's not being built by governments or utilities or World Bank consortiums. It's being built by startups selling solar panels to farmers on payment plans. And it's working. Over 30 million solar products sold in 2024. 400,000 new solar installations every month across Africa. 50% market share captured by companies that didn't exist 15 years ago. Carbon credits subsidizing the cost. IoT chips in every device. 90%+ repayment rates on loans to people earning $2/day. And if you understand what's happening in Africa, you understand the template for how infrastructure will get built everywhere else for the next 50 years.

A 'Peak Oil' Prediction Surprise From the International Energy Agency
"The International Energy Agency's latest outlook signals that oil demand could keep growing through to the middle of the century," reports CNBC, "reflecting a sharp tonal shift from the world's energy watchdog and raising further questions about the future of fossil fuels."In its flagship World Energy Outlook, the Paris-based agency on Wednesday laid out a scenario in which demand for oil climbs to 113 million barrels per day by 2050, up 13% from 2024 levels. The IEA had previously estimated a peak in global fossil fuel demand before the end of this decade and said that, in order to reach net-zero emissions by 2050, there should be no new investments in coal, oil and gas projects... The IEA's end-of-decade peak oil forecast kick-started a long-running war of words with OPEC, an influential group of oil exporting countries, which accused the IEA of fearmongering and risking the destabilization of the global economy. The IEA's latest forecast of increasing oil demand was outlined in its "Current Policies Scenario" — one of a number of scenarios outlined by the IEA. This one assumes no new policies or regulations beyond those already in place. The CPS was dropped five years ago amid energy market turmoil during the coronavirus pandemic, and its reintroduction follows pressure from the Trump administration... Gregory Brew, an analyst at Eurasia Group's Energy, Climate and Resources team, said the IEA's retreat on peak oil demand signified "a major shift" from the group's position over the last five years. "The justifications offered for the shift include policy changes in the U.S., where slow EV penetration indicates robust oil [consumption], but is also tied to expected increases in petrochemical and aviation fuel in East and Southeast Asia," Brew told CNBC by email. "It's unlikely the agency is adjusting based on political pressure — though there has been some of that, with the Trump administration criticizing the group's supposed bias in favor of renewable energy — and the shift reflects a broader skepticism that oil demand is set to peak any time soon," he added... Alongside its CPS, the IEA also laid out projections under its so-called "Stated Policies Scenario" (STEPS), which reflects the prevailing direction of travel for the global energy system. In this assumption, the IEA said it expects oil demand to peak at 102 million barrels per day around 2030, before gradually declining. Global electric car sales are much stronger under this scenario compared to the CPS. The IEA said its multiple scenarios explore a range of consequences from various policy choices and should not be considered forecasts. Thanks to Slashdot reader magzteel for sharing the news.

Jack Dorsey Funds diVine, a Vine Reboot That Includes Vine's Video Archive
An anonymous reader quotes a report from TechCrunch: As generative AI content starts to fill our social apps, a project to bring back Vine's six-second looping videos is launching with Twitter co-founder Jack Dorsey's backing. On Thursday, a new app called diVine will give access to more than 100,000 archived Vine videos, restored from an older backup that was created before Vine's shutdown. The app won't just exist as a walk down memory lane; it will also allow users to create profiles and upload their own new Vine videos. However, unlike on traditional social media, where AI content is often haphazardly labeled, diVine will flag suspected generative AI content and prevent it from being posted. According to TechCrunch, a volunteer preservation group called the Archive Team saved Vine's content when it shut down in 2016. The only problem was that everything was stored in massive 40-50 GB binary blob files that were basically unusable for casual viewing. Evan Henshaw-Plath (who goes by the name Rabble), an early Twitter employee and member of Jack Dorsey's nonprofit "and Other Stuff," dug into those backup files to try and salvage as much as he could. He spent months writing big-data extraction scripts, reverse-engineering how the archived binaries were structured, and reconstructing the original video files, old user info, view counts, and more. "I wasn't able to get all of them out, but I was able to get a lot out and basically reconstruct these Vines and these Vine users, and give each person a new user [profile] on this open network," he said. Rabble estimates that through this process he was able to successfully recover 150,000-200,000 Vine videos from around 60,000 creators. diVine then rebuilt user profiles on top of the decentralized Nostr protocol so creators can reclaim their accounts, request takedowns, or upload missing videos. You can check out the app for yourself at diVine.video. It's available in beta form on both iOS and Android.

Russia's AI Robot Falls Seconds After Being Unveiled
Russia's first AI humanoid robot, Aldol, fell just seconds after its debut at a technology event in Moscow on Tuesday. "The robot was being led on stage to the soundtrack from the film 'Rocky,' before it suddenly lost its balance and fell," reports the BBC. "Assistants could then be seen scrambling to cover it with a cloth -- which ended up tangling in the process." Developers of Aldol blamed poor lighting and calibration issues for the collapse, saying the robot's stereo cameras are sensitive to light and the hall was dark.

Ask Slashdot: Are There Any Good Android Tablets Out There?
Longtime Slashdot reader hadleyburg writes: For a user with an Android phone and who's happy to stick within the Google ecosystem, an Android tablet might seem like the more obvious choice over an iPad. Of course, iPads are a lot more popular, and asking about Android tablets is likely to invite advice about sticking with what everyone else has. The Slashdot community on the other hand -- being a discerning and thoughtful crowd -- might have some experience in this area and be willing to share the pros and cons they have found.

Valve Rejoins the VR Hardware Wars With Standalone Steam Frame
Valve is ready to rejoin the VR hardware race with the Steam Frame, a lightweight standalone SteamOS headset that can run games locally or stream wirelessly from a PC using new "foveated streaming" tech. It's set to launch in early 2026. Ars Technica reports: Powered by a Snapdragon 8 Gen 3 processor with 16 GB of RAM, the Steam Frame sports a 2160 x 2160 resolution display per eye at an "up to 110 degrees" field-of-view and up to 144 Hz. That's all roughly in line with 2023's Meta Quest 3, which runs on the slightly less performant Snapdragon XR2 Gen 2 processor. Valve's new headset will be available in models sporting 256GB and 1TB or internal storage, both with the option for expansion via a microSD card slot. Pricing details have not yet been revealed publicly. The Steam Frame's inside-out tracking cameras mean you won't have to set up the awkward external base stations that were necessary for previous SteamVR headsets (including the Index). But that also means old SteamVR controllers won't work with the new hardware. Instead, included Steam Frame controllers will track your hand movements, provide haptic feedback, and offer "input parity with a traditional game pad" through the usual buttons and control sticks. For those who want to bring desktop GPU power to their VR experience, the Steam Frame will be able to connect wirelessly to a PC using an included 6 GHz Wi-Fi 6E adapter. That streaming will be enhanced by what Valve is calling "foveated rendering" technology, which sends the highest-resolution video stream to where your eyes are directly focused (as tracked by two internal cameras). That will help Steam Frame streaming establish a "fast, direct, low-latency link" to the machine, Valve said, though the company has yet to respond to questions about just how much additional wireless latency users can expect.

Data Centers in Nvidia's Hometown Stand Empty Awaiting Power
Two of the world's biggest data center developers have projects in Nvidia's hometown that may sit empty for years because the local utility isn't ready to supply electricity. From a report: In Santa Clara, California, where the world's biggest supplier of artificial-intelligence chips is based, Digital Realty Trust applied in 2019 to build a data center. Roughly six years later, the development remains an empty shell awaiting full energization. Stack Infrastructure, which was acquired earlier this year by Blue Owl Capital, has a nearby 48-megawatt project that's also vacant, while the city-owned utility, Silicon Valley Power, struggles to upgrade its capacity. The fate of the two facilities highlights a major challenge for the US tech sector and indeed the wider economy. While demand for data centers has never been greater, driven by the boom in cloud computing and AI, access to electricity is emerging as the biggest constraint. That's largely because of aging power infrastructure, a slow build-out of new transmission lines and a variety of regulatory and permitting hurdles. And the pressure on power systems is only going to increase. Electricity requirements from AI computing will likely more than double in the US alone by 2035, based on BloombergNEF projections. Nvidia's Jensen Huang and OpenAI's Sam Altman are among corporate leaders that have predicted trillions of dollars will pour into building new AI infrastructure.
