"A new type of battery storage is about to be deployed on the Midwestern grid for the first time," reports Electrek: Sodium-ion battery storage manufacturer Peak Energy and global energy company RWE Americas will pilot a passively cooled sodium-ion battery system in eastern Wisconsin on the Midcontinent Independent System Operator network — the first sodium-ion deployment on that grid. Peak Energy says its technology is specifically designed for grid-scale storage and leverages sodium-ion chemistry's inherent stability. Unlike many lithium-ion systems, sodium-ion batteries don't require active cooling and can operate over a wide temperature range without losing performance. That simpler design could make a meaningful dent in the cost of storing electricity. According to Peak Energy, its system cuts the lifetime cost of stored energy by an average of $70 per kilowatt-hour. That's roughly half the total cost of a typical battery system today. The company says it achieves those savings by removing energy-hungry cooling systems, eliminating routine maintenance requirements, and reducing the need to overbuild storage capacity to account for battery degradation over time... If the Wisconsin pilot proves successful, it could open the door to wider adoption of sodium-ion batteries for large-scale energy storage across the US.

Starting in September, even Android developers not in Google's Play Store will still be required to register with Google to distribute their apps in Brazil, Singapore, Indonesia, and Thailand, with Google continuing "to roll out these requirements globally" four months later. Even developers distributing Android apps on the web for sideloading will be required to register, pay Google a $25 fee, and provide a government ID. But there's a new theory on what's secretly been motivating Google from an unnamed source in the "Keep Android Open" movement, writes long-time Slashdot reader destinyland: "You can't separate this really from their ongoing interactions with Epic and the settlement that they came to," they argue. Twelve days ago Epic Games and Google announced a new proposal for settling their long-running dispute over the legality of alternative app stores on Android phones. (Rather than agreeing to let third-party app stores into their Play Store, Google wants them to continue being sideloaded, promising in a blog post last week that they'll even offer a "more streamlined" and "simplified" sideloading alternative for rival app stores. "This Registered App Store program will begin outside of the US first, and we intend to bring it to the US as well, subject to court approval.") So "developer verification" could be Google's fallback plan if U.S. courts fail to approve this. "If the Google Play Store has to allow any third-party repository app store, Google essentially has given up all control of the apps. But if they're able to claw back that control by requiring that all developers, no matter how they distribute their apps, have to register with Google — have to agree to their Terms & Conditions, pay them money, provide identification — then they have a large degree of indirect control over any app that can be developed for the entire platform." But that plan threatens millions of people using the alternative F/OSS app distributor F-Droid, since Google also wants to have only one signature attached to Android apps. Marc Prud'hommeaux, a member of F-Droid's board of directors, says that "all of a sudden breaks all those versions of the application distributed through F-Droid or any other app store!" Prud'hommeaux says they've told Google's Android team "You know perfectly well that you're killing F-Droid!" creating an "existential" threat to an app distributor "that has existed happily for over 10 years." But good things started happening when he created the website Keep Android Open: There's now a "huge backlog" of signers for an Open Letter that already includes EFF, the Software Freedom Conservancy, and the Free Software Foundation. He believes Android's existing Play Protect security "is completely sufficient to handle the particular scenarios they claim that developer verification is meant to address"... The Keep Android Open site urges developers not to sign up for Android's early access program when it launches next week. (Instead, they're asking developers to respond to invites with an email about their concerns — and to spread the word to other developers and organizations in forums and social media posts.) There's also a petition at Change.org currently signed by 64,000 developers — adding 20,000 new signatures in the last 10 days. And "If you have an Android device, try installing F-Droid!" he adds. Google tracks how many people install these alternative app repositories, and a larger user base means greater consequences from any Android policy changes. Plus, installing F-Droid "might be refreshing!" Prud'hommeaux says. "You don't see all the advertisements and promotions and scam and crapware stuff that you see in the commercial app stores!"

In 2024 Anthropic was sued over claims it infringed copyrights when training LLMs. But as they try to settle, they may have a problem. The Free Software Foundation announced Friday that Anthropic's training data apparently even included the book "Free as in Freedom: Richard Stallman's Crusade for Free Software" — for which the Free Software Foundation holds a copyright. It was published by O'Reilly and by the FSF under the GNU Free Documentation License (GNU FDL). This is a free license allowing use of the work for any purpose without payment. Obviously, the right thing to do is protect computing freedom: share complete training inputs with every user of the LLM, together with the complete model, training configuration settings, and the accompanying software source code. Therefore, we urge Anthropic and other LLM developers that train models using huge datasets downloaded from the Internet to provide these LLMs to their users in freedom. We are a small organization with limited resources and we have to pick our battles, but if the FSF were to participate in a lawsuit such as Bartz v. Anthropic and find our copyright and license violated, we would certainly request user freedom as compensation. "The FSF doesn't usually sue for copyright infringement," reads the headline on the FSF's announcement, "but when we do, we settle for freedom."

The UK's science minister is announcing details of a five-year, £2.5 billion investment in nuclear fusion, reports the Times of London, "including building one of the world's first prototype fusion power plants in Nottinghamshire and developing a UK sector projected to employ 10,000 people by 2030." Despite the potentially transformative impact of fusion, which in theory could provide limitless clean energy and create a £12 trillion global market, no country has managed to use this fledgling technology to generate useable electricity... [T]he UK is backing a spherical tokamak design... investing an initial £1.3 billion into a prototype fusion power plant called Step (Spherical Tokamak for Energy Production) on the site of a decommissioned coal-fired power station at West Burton in Nottinghamshire. Paul Methven, chief executive of the government-owned UK Industrial Fusion Solutions, which is delivering the Step project, said the aim is to get the reactor operating early in the 2040s. "It's quite an aggressive programme," he said. "We need to show that we can achieve genuine 'wall socket' energy — which has not been done before." On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds... Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.
