An anonymous reader quotes a report from The Guardian: The amount of wind and solar power under construction in China is now nearly twice as much as the rest of the world combined, a report has found. Research published on Thursday by Global Energy Monitor (GEM), an NGO, found that China has 180 gigawatts (GW) of utility-scale solar power under construction and 15GW of wind power. That brings the total of wind and solar power under construction to 339GW, well ahead of the 40GW under construction in the US. The researchers only looked at solar farms with a capacity of 20MW or more, which feed directly into the grid. That means that the total volume of solar power in China could be much higher, as small scale solar farms account for about 40% of China's solar capacity.

Between March 2023 and March 2024, China installed more solar than it had in the previous three years combined, and more than the rest of the world combined for 2023, the GEM analysts found. China is on track to reach 1,200GW of installed wind and solar capacity by the end of 2024, six years ahead of the government's target. "The unabated wave of construction guarantees that China will continue leading in wind and solar installation in the near future, far ahead of the rest of the world," the report said. Earlier analysis suggests that China will need to install between 1,600GW and 1,800GW of wind and solar energy by 2030 to meet its target of producing 25% of all energy from non-fossil sources. Between 2020 and 2023, only 30% of the growth in energy consumption was met by renewable sources, compared with the target of 50%.

Today, Amazon announced that it reached its 100% renewable energy goal seven years ahead of schedule. However, as Fast Company's Adele Peters reports, "a group of Amazon employees argues that the company's math is misleading." From the report: A report (PDF) from the group, Amazon Employees for Climate Justice, argues that only 22% of the company's data centers in the U.S. actually run on clean power. The employees looked at where each data center was located and the mix of power on the regional grids -- how much was coming from coal, gas, or oil versus solar or wind. Amazon, like many other companies, buys renewable energy credits (RECs) for a certain amount of clean power that's produced by a solar plant or wind farm. In theory, RECs are supposed to push new renewable energy to get built. In reality, that doesn't always happen. The employee research found that 68% of Amazon's RECs are unbundled, meaning that they didn't fund new renewable infrastructure, but gave credit for renewables that already existed or were already going to be built.

As new data centers are built, they can mean that fossil-fuel-dependent grids end up building new fossil fuel power plants. "Dominion Energy, which is the utility in Virginia, is expanding because of demand, and Amazon is obviously one of their largest customers," says Eliza Pan, a representative from Amazon Employees for Climate Justice and a former Amazon employee. "Dominion's expansion is not renewable expansion. It's more fossil fuels." Amazon also doesn't buy credits that are specifically tied to the grids powering their data centers. The company might purchase RECs from Canada or Arizona, for example, to offset electricity used in Virginia. The credits also aren't tied to the time that the energy was used; data centers run all day and night, but most renewable energy is only available some of the time. The employee group argues that the company should follow the approach that Google takes. Google aims to use carbon-free energy, 24/7, on every grid where it operates.

"Nature recently published an open-access article (not paywalled) that studies the lifecycle of lithium-ion batteries once they are manufactured," writes Slashdot reader NoWayNoShapeNoForm. "The study is a 'cradle-to-grave' look at these batteries and certain chemicals that they contain. The University researchers that authored the study found that the electrolytes and polymers inside lithium-ion batteries contain a class of PFAS known as bis-FASI chemicals. PFAS chemicals are internationally recognized pollutants, yet they are found in consumer and industrial processes, such as non-stick coatings, surfactants, and film-forming foams. PFAS chemicals have been found in windmill coatings, semiconductors, solar collectors, and photovoltaic cells." Phys.org reports: Texas Tech University's Jennifer Guelfo was part of a research team that found the use of a novel sub-class of per- and polyfluoroalkyl (PFAS) in lithium ion batteries is a growing source of pollution in air and water. Testing by the research team further found these PFAS, called bis-perfluoroalkyl sulfonimides (bis-FASIs), demonstrate environmental persistence and ecotoxicity comparable to older notorious compounds like perfluorooctanoic acid (PFOA). The researchers sampled air, water, snow, soil and sediment near manufacturing plants in Minnesota, Kentucky, Belgium and France. The bis-FASI concentrations in these samples were commonly at very high levels. Data also suggested air emissions of bis-FASIs may facilitate long-range transport, meaning areas far from manufacturing sites may be affected as well. Analysis of several municipal landfills in the southeastern U.S. indicated these compounds can also enter the environment through disposal of products, including lithium ion batteries.

Toxicity testing demonstrated concentrations of bis-FASIs similar to those found at the sampling sites can change behavior and fundamental energy metabolic processes of aquatic organisms. Bis-FASI toxicity has not yet been studied in humans, though other, more well-studied PFAS are linked to cancer, infertility and other serious health harms. Treatability testing showed bis-FASIs did not break down during oxidation, which has also been observed for other PFAS. However, data showed concentrations of bis-FASIs in water could be reduced using granular activated carbon and ion exchange, methods already used to remove PFAS from drinking water. "Our results reveal a dilemma associated with manufacturing, disposal, and recycling of clean energy infrastructure," said Guelfo, an associate professor of environmental engineering in the Edward E. Whitacre Jr. College of Engineering. "Slashing carbon dioxide emissions with innovations like electric cars is critical, but it shouldn't come with the side effect of increasing PFAS pollution. We need to facilitate technologies, manufacturing controls and recycling solutions that can fight the climate crisis without releasing highly recalcitrant pollutants."

An anonymous reader quotes a report from TechCrunch: Fast-food chain Whataburger's app has gone viral in the wake of Hurricane Beryl, which left around 1.8 million utility customers in Houston, Texas without power. Hundreds of thousands of those people may remain without power for days as Houston anticipates a heat wave, with temperatures climbing into the mid-90s. Amid frustrations with the local utility company CenterPoint Energy, which doesn't offer an app, some Houstonians got creative with their attempts to track the power outages. They turned to the Whataburger app instead.

Whataburger is a San Antonio-based fast-food chain with 127 stores in the Houston area, according to Newsweek. On the Whataburger app, users can see a map of Whataburger locations, with an orange logo indicating a store is open, and a grey logo meaning it's closed. Since CenterPoint Energy doesn't have an online map of outages, an X user with the screen name BBQBryan found that the map of which Whataburger stores are open could be a useful tool for seeing where there's power. This viral moment seems to have boosted Whataburger's download numbers. In the iOS App Store, Whataburger is currently ranked 16th in the food and drink category. Just three weeks ago, it was ranked 40th. "The Whataburger app works as a power outage tracker, handy since the electric company doesn't show a map," BBQBryan wrote in a post that now has over 22,000 likes and 6.9 million impressions.

"Well there's a use for our app we didn't think of!" the Whataburger X account replied. "We hope you and everyone else are okay!"

At its Galaxy Unpacked event today, Samsung unveiled a slew of new devices ushering in the "Next Frontier of Mobile AI." With "cross-device intelligence," each device has its own set of AI features that Samsung said will be personalized for users, good for humanity, and empowering for creators. Ars Technica's Kevin Purdy reports: Aiming to put its Galaxy AI onto your wrist and fingers, Samsung announced a seventh version of its Galaxy Watch, a rugged and larger Galaxy Watch Ultra, and the first version of a Galaxy Ring. [...] The Galaxy Watch 7 and Watch Ultra are strikingly similar to their inspirations: the Apple Watch Ultra and the previous Galaxy Watch, respectively. [...] The Galaxy Z Fold 6 ($1,900) and Z Flip 6 ($1,100) have the kinds of boosts from their prior models you might expect. There's a Snapdragon 8 Gen 3 chip inside. The folding glass on both is supposedly stronger and now rated for IP48, which means dust resistance went from "X" (good luck) to "4" (1 mm and greater particles), which is still unfortunate at these price points, but that's life on the folding edge.

The outward-facing screen on the Z Fold 6 got a smidge bigger (6.2 to 6.3 inches), though it has the same inner display. Its cameras are much the same (50 megapixel main, 10 megapixel telephoto, 12 megapixel ultrawide), though the ultrawide claims better low-light performance. The Z Flip 6's most notable upgrade is its 4,000 mAh battery and a vapor cooling chamber inside. The base model gets 12GB of RAM instead of 8GB and 512GB of storage instead of 256GB on the base model.

There are other products not mentioned here announced by Samsung today, including its Galaxy Buds3 and Buds3 Pro, which are wireless earbuds that will remind you of certain other very popular wireless earbuds. What Samsung really had to pitch today was how its own Galaxy AI was the connective tissue between all of them. The screens on the Fold and Flip models are ideal for circling things to search them. The cameras can auto-zoom, the notes can be summarized, and translations, in particular, are everywhere. The watches and rings can track your health and suggest ways to make it better in all kinds of ways that merit a lot of disclosure about where all that data is going. Rick Osterloh, Google's devices and services chief, showed up to give a kind of Gemini blessing to Samsung's efforts.

Alberta's last coal plant went offline on June 16, marking the end of coal-fired electricity in the province. "So, for the first time in 150 years, coal is no longer part of Alberta's electricity mix," writes Chris Severson-Baker in an opinion piece for The Globe and Mail. "It is important to celebrate and reflect on these milestones, while recognizing there is no time to rest before redoubling our efforts and looking to what's next." From the report: Many organizations contributed to this successful campaign through advocacy and research. The Canadian Association of Physicians for the Environment, the Lung Association and the Asthma Society of Canada were instrumental in highlighting the health impacts associated with air pollution from coal-fired electricity. The Pembina Institute, an Alberta-based clean-energy think tank, first intervened in a coal plant regulatory process in the late 1990s and, in 2009, published the first major proposal that showed the province could move to an unabated coal-free grid by 2030. Our research was ahead of its time and criticized as idealistic.

Coal accounted for 80 per cent of Alberta's electricity grid in the early 2000s and it still amounted to 60 per cent just 10 years ago. When phasing out coal was just an idea being batted around, many said it couldn't be done. This is not dissimilar to the rhetoric today around decarbonizing the grid. But Alberta's experience phasing out coal shows environmental progress of this magnitude is possible. [...] Phasing out coal in Alberta was supported by good policy design driven by carbon pricing and regulations with clear targets that offered necessary certainty to the industry and stakeholders. Rapidly growing, low-cost renewable energy further supported the phase-out, along with companies investing in gas-fired electricity. All these actions accelerated the transition away from coal at a faster rate than anticipated. Chris Severson-Baker is the executive director of the Pembina Institute, a Canadian non-profit think tank focused on advancing clean energy solutions and sustainable environmental practices through research, advocacy, and collaboration.

An anonymous reader writes: Per a report from DruckerChannel, HP has finally been forced to discontinue its cheaper e-series LaserJet printers due to customers experiencing problems with their online-only and always tied to HP+ subscription requirements. Among other things, HP+ requires a permanent Internet connection, and customers only use HP-original ink and toners, not allowing for third-party alternatives to be used at all. There are benefits to HP+, including cloud printing and an extra year's warranty, but the forced online requirement for a cheaper printer left a bad taste in the mouths of many consumers.

In any case, it's important to clarify that this discontinuation of HP printers will only impact HP LaserJet printers that have an "e" added to the end of their model name to denote the alternative business model. So, the HP Laserjet M110w is unaffected by this, but the HP LaserJet M110we and M209dwe, two cheaper always-online alternatives, will no longer be produced or sold by HP. Another critical point of clarification is that the existing HP e-series LaserJet printer models in the wild will still function exactly as they did when they were purchased. No software updates are forthcoming to unlock the true potential of the hardware, so existing customers will have to deal with it and HP+ until they can replace their printers entirely. At least they'll still get HP+ benefits, but after such backlash, it'd be nice if HP acknowledged its mistake enough to remove some of the restrictions on e-series printer users.

Remember those researchers who spent years training AI tools to analyze the reviews drivers left on the smartphone apps where they pay for EV charging?

There was one more unexpected finding. "Rideshare drivers who work for companies such as Uber are increasingly turning to electric vehicles to reduce fuel costs." That trend is boosting demand for conveniently located, publicly accessible EV chargers... "They are mostly relying on public chargers for their daily Uber needs, usually every day or every couple of days, which dramatically increases electric vehicle miles traveled," [climate fellow Omar Asensio told the Institute's blog], explaining that many drivers live in apartments that lack garages or space for a residential EV charger. Uber CEO Dara Khosrowshahi considers the issue so pressing he urged U.S. policymakers to accelerate plans to improve the nation's EV charging infrastructure in a Fast Co. op-ed in January — during the World Economic Forum in Davos, when media messaging can influence policymakers.

Independent Uber drivers, Khosrowshahi said, are converting to electric vehicles seven times faster than the general public and they tend to be disproportionately from low- and middle-income households that need access to public charging stations. "Charging infrastructure must be more equitable," Khosrowshahi wrote. "Many drivers don't have driveways or garages, so access to nearby overnight charging is essential. Yet our data shows us that Uber drivers often live in neighborhoods lacking this infrastructure. These 'charging deserts' hold countless people back from making the switch."

Harvard Business School has an "Institute for Business in Global Society" that explores the societal impacts of business. And they've recently published some new AI-powered research about EV charging infrastructure, according to the Institute's blog, conducted by climate fellow Omar Asensio.

"Asensio and his team, supported by Microsoft and National Science Foundation awards, spent years building models and training AI tools to extract insights and make predictions," using the reviews drivers left (in more than 72 languages) on the smartphone apps drivers use to pay for charging. And ultimately this research identified "a significant obstacle to increasing electric vehicle (EV) sales and decreasing carbon emissions in the United States: owners' deep frustration with the state of charging infrastructure, including unreliability, erratic pricing, and lack of charging locations..." [C]harging stations in the U.S. have an average reliability score of only 78%, meaning that about one in five don't work. They are, on average, less reliable than regular gas stations, Asensio said. "Imagine if you go to a traditional gas station and two out of 10 times the pumps are out of order," he said. "Consumers would revolt...." EV drivers often find broken equipment, making charging unreliable at best and simply not as easy as the old way of topping off a tank of gas. The reason? "No one's maintaining these stations," Asensio said.
One problem? Another blog post by the Institute notes that America's approach to public charging has differed sharply from those in other countries: In Europe and Asia, governments started making major investments in public charging infrastructure years ago. In America, the initial thinking was that private companies would fill the public's need by spending money to install charging stations at hotels, shopping malls and other public venues. But that decentralized approach failed to meet demand and the Biden administration is now investing heavily to grow the charging network and facilitate EV sales... "No single market actor has sufficient incentive to build out a national charging network at a pace that meets our climate goals," the report declared. Citing research and the experience of other countries, it noted that "policies that increase access to charging stations may be among the best policies to increase EV sales." But the U.S. is far behind other countries.

John Timmer reports via Ars Technica: On Tuesday, the people managing the ITER experimental fusion reactor announced (PDF) that a combination of delays and altered priorities meant that its first-of-its-kind hardware wouldn't see plasma until 2036, with the full-energy deuterium-tritium fusion pushed back to 2039. The latter represents a four-year delay relative to the previous roadmap. While the former is also a delay, it's due in part to changing priorities.

ITER is an attempt to build a fusion reactor that's capable of sustaining plasmas that allow it to operate well beyond the break-even point, where the energy released by fusion reactions significantly exceeds the energy required to create the conditions that enable those reactions. It's meant to hit that milestone by scaling up a well-understood design called a tokamak. But the problem has been plagued by delays and cost overruns nearly from its start. At early stages, many of these stemmed from changes in designs necessitated by a better and improved understanding of plasmas held at extreme pressures and temperatures due to better modeling capabilities and a better understanding of the behavior of plasmas in smaller reactions.

The latest delays are due to more prosaic reasons. One of them is the product of the international nature of the collaboration, which sees individual components built by different partner organizations before assembly at the reactor site in France. The pandemic, unsurprisingly, severely disrupted the production of a lot of these components, and the project's structure meant that alternate suppliers couldn't be used (assuming alternate suppliers of one-of-a-kind hardware existed in the first place). The second problem relates to the location of the reactor in France. The country's nuclear safety regulator had concerns about the assembly of some of the components and halted construction on the reactor.

Longtime Slashdot reader theodp writes: "If Einstein paved the way for a new era in physics," explains auction house Christie's in a promotion piece for its upcoming offering of 150+ "objects of scientific and historical importance" from the Paul G. Allen Collection (including items from the shuttered Living Computers Museum), "Mr. Allen and his collaborators ushered in a new era of computing. Starting with MS-DOS in 1981, Microsoft then went on to revolutionize personal computing with the launch of Windows in 1985."

Christie's auction and characterization of MS-DOS as an Allen and Microsoft innovation comes 30 years after the death of Gary Kildall, whose unpublished memoir, the Seattle Times reported in Kildall's July 1994 obituary, called DOS "plain and simple theft" of Kildall's CP/M OS. PC Magazine's The Rise of DOS: How Microsoft Got the IBM PC OS Contract notes that Paul Allen himself traced the genesis of MS-DOS back to a phone call Allen made to Seattle Computer Products owner Rod Brock in which Microsoft licensed Tim Paterson's CP/M-inspired QDOS (Quick and Dirty Operating System) for $10,000 plus a royalty of $15,000 for every company that licensed the software. A shrewd buy-low-sell-high business deal, yes, but hardly an Einstein-caliber breakthrough idea.

An anonymous reader shares a report: It resembles an enormous, malevolent robot from 1980s sci-fi but West Japan Railway's new humanoid employee was designed with nothing more sinister than a spot of painting and gardening in mind. Starting this month, the large machine with enormous arms, a crude, disproportionately small Wall-E-like head and coke-bottle eyes mounted on a truck -- which can drive on rails -- will be put to use for maintenance work on the company's network. Its operator sits in a cockpit on the truck, "seeing" through the robot's eyes via cameras and operating its powerful limbs and hands remotely. With a vertical reach of 12 metres (40ft), the machine can use various attachments for its arms to carry objects as heavy as 40kg (88lb), hold a brush to paint or use a chainsaw. For now, the robot's primary task will focus on trimming tree branches along rails and painting metal frames that hold cables above trains, the company said. The technology will help fill worker shortages in ageing Japan as well as reduce accidents such as workers falling from high places or suffering electric shocks, the company said.

Matthew Connatser reports via The Register: Utility firms American Electric Power (AEP) and Exelon have filed an official objection with the Federal Energy Regulatory Commission (FERC) over Talen Energy's nuclear power deal with Amazon. Back in March, Amazon bought a nuclear-powered datacenter from Talen Energy -- an operator of electricity generation and transmission facilities in the US. As part of the deal, Amazon would get 480 MW straight from the 2.7 GW Talen nuclear power plant in Susquehanna, Pennsylvania, and may even be able to upgrade to 960 MW down the line. However, that Susquehanna atomic plant also provides power to PJM Interconnection, the regional power grid operator for much of the eastern US. The two companies -- Talen and PJM -- have an interconnection service agreement (ISA) that sets the rules for how Talen should deliver power to PJM's transmission system.

To better accommodate the nuclear datacenter, Talen and PJM agreed to a new ISA, which has caught the ire of AEP and Exelon. The duo claim Talen and Amazon are basically getting a free ride that other PJM ratepayers will have to pay for, saying that even though Amazon's datacenter isn't directly connected to PJM, it still benefits from the power grid, meaning the other ratepayers are left holding the short end of the stick. Each of the station's two reactors has 1,350 MW available, and Amazon is already able to use 480 MW, and up to 960 MW in the future. If one of the reactors experiences an outage, the ISA says the datacenter is first in line for power from the other reactor, which leaves PJM with far less electricity than normal. That in turn would mean a lower energy supply for PJM's customers, who would have to pay more, at least according to the complaint's reasoning. The Talen-PJM ISA states that in this event, the nuclear datacenter will separate from the plant and get its power elsewhere, but AEP and Exelon are skeptical and want to know how exactly that would work.

The complaint argues Amazon's DC is essentially using the grid, saying the "premise" of the tweaked ISA "is that this datacenter co-located load is like load on a remote island -- one that simply has no impact on the PJM grid and would thus be properly excluded from economic and other responsibility for maintaining the PJM grid. But that storyline does not stand up to scrutiny." "They present their filing as no more than a replacement of older agreements with updated terms and 'clarifications' regarding the parties' roles and obligations," the two utility companies told [PDF] FERC, requesting a hearing over the matter. "The filing [new ISA] casts the submission as a mere housekeeping exercise, as if there is nothing to see here."

The protest adds: "The co-located load should not be allowed to operate as a free rider, making use of, and receiving the benefits of, a transmission system paid for by transmission ratepayers. We have no objection to co-location per se, but such load should pay its fair share of system use and other charges, just like other loads and customers." AEP and Exelon claim the new terms of the ISA contains a key loophole that hinges on the datacenter's co-location with the nuclear power plant, which allows its power usage to not be considered "in-network," even though the power load is synced to PJM's grid and could theoretically get power from it. [...] The end result, or so AEP and Exelon allege, is that Talen would be able to benefit from PJM's services without the associated cost. That would cost other customers between $58 million and $140 million per year overall, according to an analysis from Concentric Energy Advisors CEO Danielle Powers and chairman John Reed included with the filing. AEP and Exelon asked FERC to either hold a hearing to answer questions it feels are unresolved or to reject the new ISA outright. For its part, Talen claims the complaint's narrative is "demonstrably false" and that "transmission is not implicated."

The FTC has issued warnings to several tech firms, including PC manufacturers ASRock, Gigabyte, and Zotac, regarding potential violations of the Magnuson-Moss Warranty Act. The agency expressed concerns that the companies' warranty and repair policies may be infringing on consumer rights. PCWorld adds: While the specific concerns vary by company, the FTC reminded the three companies that they can't, for example, place stickers on a laptop that caution consumers that opening or repairing the laptop violates warranty policies.

Neither can they state or imply that their products can only be repaired via an authorized service from the company. In the letter sent to Gigabyte (PDF), the FTC said that its staff is "concerned" by the Gigabyte written warranty, which includes the phrase: "If the manufacturing sticker inside the product was removed or damaged, it would no longer be covered by the warranty."

An anonymous reader shares a report: Sony plans to eventually stop producing consumer-grade recordable Blu-ray discs, but commercial products such as game and film Blu-rays will still be produced. Sony Group will lay off 250 employees at a division that produces recordable media discs, and start winding down the production of specific Blu-ray products, sources have told Japanese newspaper Mainichi.

However, contrary to recent reports, this decision will not affect Blu-ray discs that contain games, TV shows, or films. The staff reduction is happening to the Sony Sendai Technology Center, which produces recordable disc formats like CD-R, DVD-R, BD-R and archival discs for the Japanese region. Standard Blu-rays, 4K UHD discs, and PlayStation 4, PlayStation 5, and Xbox Blu-ray discs--which are made at Sony's separate DADC (Digital Audio Disc Corporation) facility--will still be manufactured, shipped, and sold worldwide. In other words, physical media will not go anywhere anytime soon, despite the prevalence and growth of streaming and/or digital media.

Astro is leaving its job to spend more time with family. From a report: Amazon informed customers and employees Wednesday morning that it plans to discontinue its Astro for Business program, less than a year after launching the robot security guard for small- and medium-sized businesses. The decision will help the company focus on its home version of Astro, according to an internal email. Astro for Business robots will stop working Sept. 25, the company said in a separate email to customers, encouraging them to recycle the devices.

Businesses will receive full refunds for the original cost of the device, plus a $300 credit "to help support a replacement solution for your workplace," the email said. They will also receive refunds for unused, pre-paid Astro Secure subscription fees. Announced in November 2023, the business version of Amazon's rolling robot used an HD periscope and night vision technology to autonomously patrol and map up to 5,000 square feet of space. It followed preprogrammed routes and routines, and could be controlled manually and remotely via the Amazon Astro app.

Tech companies scouring the country for electricity supplies have zeroed in on a key target: America's nuclear-power plants. From a report: The owners of roughly a third of U.S. nuclear-power plants are in talks with tech companies to provide electricity to new data centers needed to meet the demands of an artificial-intelligence boom. Among them, Amazon Web Services is nearing a deal for electricity supplied directly from a nuclear plant on the East Coast with Constellation Energy, the largest owner of U.S. nuclear-power plants, according to people familiar with the matter. In a separate deal in March, the Amazon subsidiary purchased a nuclear-powered data center in Pennsylvania for $650 million.

The discussions have the potential to remove stable power generation from the grid while reliability concerns are rising across much of the U.S. and new kinds of electricity users -- including AI, manufacturing and transportation -- are significantly increasing the demand for electricity in pockets of the country. Nuclear-powered data centers would match the grid's highest-reliability workhorse with a wealthy customer that wants 24-7 carbon-free power, likely speeding the addition of data centers needed in the global AI race. But instead of adding new green energy to meet their soaring power needs, tech companies would be effectively diverting existing electricity resources. That could raise prices for other customers and hold back emission-cutting goals.

Longtime Slashdot reader fahrbot-bot shares a report from CNN, written by Olesya Dmitracova: Nyobolt, based in Cambridge, has developed a new 35kWh lithium-ion battery that was charged from 10% to 80% in just over four and a half minutes in its first live demonstration last week. [...] Nyobolt's technology builds on a decade of research led by University of Cambridge battery scientist Clare Grey and Cambridge-educated Shivareddy, the company said. Key to its batteries' ability to be charged super-fast without a big impact on their longevity is a design that means they generate less heat. It also makes them safer as overheating can cause a lithium-ion battery to catch fire and explode. In addition, the materials used to make the batteries' anodes allow for a faster transfer of electrons. Nyobolt is currently in talks to sell its batteries to eight electric car manufacturers. At 35 kWh, the battery is much smaller than the 85 kWh in a more typical American electric vehicle (EV). Yet the technology may be used in larger battery packs in the future.

Independent testing of Nyobolt's batteries by what it called a leading global manufacturer found that they can achieve over 4,000 fast-charge cycles, equivalent to 600,000 miles (965,600 kilometers), while retaining more than 80% of capacity, Nyobolt said in its Friday statement. William Kephart, an e-mobility specialist at consultancy P3 Group and a former engineer, said EV batteries of the kind Nyobolt has developed could "theoretically" be charged as fast as the firm is promising, but the challenge was manufacturing such batteries on an industrial scale. A crucial chemical element in Nyobolt's batteries is niobium but, as Kephart pointed out, last year only an estimated 83,000 tons (94,500 tons) was mined worldwide. Compare that with graphite, commonly used as anode material in lithium-ion batteries: an estimated 1.6 million tons (1.8 million tons) was produced in 2023. In addition, there are currently "a lot of unknowns" with the niobium battery technology, he told CNN. "The industry will work it out (but) it's not seen by the industry as a scalable technology just yet," he added.

An anonymous reader quotes a report from the Financial Times: Google's greenhouse gas emissions have surged 48 percent in the past five years due to the expansion of its data centers that underpin artificial intelligence systems, leaving its commitment to get to "net zero" by 2030 in doubt. The Silicon Valley company's pollution amounted to 14.3 million tons of carbon equivalent in 2023, a 48 percent increase from its 2019 baseline and a 13 percent rise since last year, Google said in its annual environmental report on Tuesday. Google said the jump highlighted "the challenge of reducing emissions" at the same time as it invests in the build-out of large language models and their associated applications and infrastructure, admitting that "the future environmental impact of AI" was "complex and difficult to predict."

Chief sustainability officer Kate Brandt said the company remained committed to the 2030 target but stressed the "extremely ambitious" nature of the goal. "We do still expect our emissions to continue to rise before dropping towards our goal," said Brandt. She added that Google was "working very hard" on reducing its emissions, including by signing deals for clean energy. There was also a "tremendous opportunity for climate solutions that are enabled by AI," said Brandt. [...] In Tuesday's report, Google said its 2023 energy-related emissions -- which come primarily from data center electricity consumption -- rose 37 percent year on year, and overall represented a quarter of its total greenhouse gas emissions. Google's supply chain emissions -- its largest chunk, representing 75 percent of its total emissions -- also rose 8 percent. Google said they would "continue to rise in the near term" as a result in part of the build-out of the infrastructure needed to run AI systems.

Google has pledged to achieve net zero across its direct and indirect greenhouse gas emissions by 2030, and to run on carbon-free energy during every hour of every day within each grid it operates by the same date. However, the company warned in Tuesday's report that the "termination" of some clean energy projects during 2023 had pushed down the amount of renewables it had access to. Meanwhile, the company's data centre electricity consumption had "outpaced" Google's ability to bring more clean power projects online in the US and Asia-Pacific regions. Google's data centre electricity consumption increased 17 percent in 2023, and amounted to approximately 7-10 percent of global data center electricity consumption, the company estimated.Its data centers also consumed 17 percent more water in 2023 than during the previous year, Google said.

To stop their smartphone battery from swelling, long-time Slashdot reader shanen bought a Samsung Galaxy with a "restrictive charging option." But what setting should they use? The way this battery protection option worked was to stop charging the phone at 85%. That left me enough charge for my normal daily travels, which rarely took the phone below 50%, and the battery remained unswollen after a year, which included a month of quite heavy tethering, too. Unfortunately... After a recent upgrade, now my Galaxy has three options for the battery where it had two. The 85% option is still there, but it has been lowered to 80%. I've been using that for now and it still seems good enough. However my main concern is with the best option to maximize the overall lifespan of the smartphone...

The other old option says something about using AI to control the battery charging, but I don't trust it and think it is just the old approach that causes phones to die quickly... The new third option is the one that is interesting me. This seems to be a kind of flutter charge where the phone will charge to 100% and then stop until it has dropped to 95% before charging again, even if it remains plugged in. This sounds attractive and would give me more battery insurance when I'm traveling, but maybe it reduces the overall lifetime of the phone?
They tried getting answers from Samsung, but "I think I have been flagged as a low-profit customer." And of course, this raises several other questions? (Are other smartphones better? Have iPhones solved the battery-swelling issue?) And most importantly: is there a way to charge batteries without reducing their lifespan?
