Utilities Are Trying Enormous 'Flow' Batteries Big Enough to Oust Coal Power Plants
To help replace power plants, Japan's northernmost island, Hokkaido, "is turning to a new generation of batteries designed to stockpile massive amounts of energy," reports the Washington Post. "The Hokkaido Electric Power Network (HEPCO Network) is deploying flow batteries, an emerging kind of battery that stores energy in hulking tanks of metallic liquid."[F]low batteries are making their debut in big real-world projects. Sumitomo Electric, the company that built the Hokkaido plant, has also built flow batteries in Taiwan, Belgium, Australia, Morocco and California. Hokkaido's flow battery farm was the biggest in the world when it opened in April 2022 — a record that lasted just a month before China built one that is eight times bigger and can deliver as much energy as an average U.S. natural gas plant. "It looks like flow batteries are finally about to take off with interest from China," said Michael Taylor, an energy analyst at the International Renewable Energy Agency, an international group that studies and promotes green energy. "When China starts to get comfortable with a technology and sees it working, then they will very quickly scale their manufacturing base if they think they can drive down the costs, which they usually can...." Lithium-ion batteries are perfect for smartphones because they're lightweight and fit in small spaces, even if they don't last long and have to be replaced frequently. Utilities have a different set of priorities: They need to store millions of times more energy, and they have much more room to work with. "If you think about utility-scale stationary applications, maybe you don't need lithium-ion batteries. You can use another one that is cheaper and can provide the services that you want like, for example, vanadium flow batteries," said Francisco Boshell, a researcher at the International Renewable Energy Agency... Flow batteries are designed to tap giant tanks that can store a lot of energy for a long time. To boost their storage capacity, all you have to do is build a bigger tank and add more vanadium. That's a big advantage: By contrast, there's no easy way to adjust the storage capacity of a lithium-ion battery — if you want more storage, you have to build a whole new battery... One major barrier to building more of these battery farms is finding enough vanadium. Three-quarters of the world's supply comes as a by-product from 10 steel mills in China and Russia, according to Kara Rodby [a battery analyst at the investment firm Volta Energy Technologies] who got her PhD at the Massachusetts Institute of Technology studying the design and market for flow batteries. Australia, South Africa and the United States also produce vanadium, but in much smaller quantities. Mines that have been proposed could boost supply. And some flow battery start-ups are trying to sidestep the vanadium problem entirely by using different materials that are easier to buy. The other hurdle is their up-front cost. Vanadium flow batteries are at least twice as expensive to build as lithium-ion batteries, Rodby said, and banks are hesitant to lend money to fund an unfamiliar technology. But experts say flow batteries can be cheaper in the long run because they're easier to maintain and last longer. A lithium-ion battery might have to be replaced after 10 years, but Rodby says flow batteries can last much longer. "There really is no finite lifetime for a flow battery in the way there is for lithium-ion," Rodby said. Here's an interesting statistic from the article. "Over the next six years, utilities will have to build 35 times as many batteries as there are today to soak up all extra renewable energy that will come online, according to the International Energy Agency."

Most Smart Device Makers Fail To Reveal Software Support Periods, FTC Finds
Nearly 89% of smart device manufacturers fail to disclose how long they will provide software updates for their products, a Federal Trade Commission staff study found this week. The review of 184 connected devices, including hearing aids, security cameras and door locks, revealed that 161 products lacked clear information about software support duration on their websites. Basic internet searches failed to uncover this information for two-thirds of the devices. "Consumers stand to lose a lot of money if their smart products stop delivering the features they want," said Samuel Levine, Director of the FTC's Bureau of Consumer Protection. The agency warned that manufacturers' failure to provide software update information for warranted products costing over $15 may violate the Magnuson Moss Warranty Act. The FTC also cautioned that companies could violate the FTC Act if they misrepresent product usability periods. The study excluded laptops, personal computers, tablets and automobiles from its review.

US To Reportedly Sanction 200 More Chinese Chip Firms
The U.S. is preparing to impose new sanctions targeting 200 Chinese chipmakers and potentially restricting the export of High Bandwidth Memory (HBM). The move is intended to further hinder China's semiconductor and AI advancements. Tom's Hardware reports: The update sheds light on the Biden administration's recent efforts to impose stricter regulations on chip manufacturers in China. The latest swarm of sanctions reportedly targets roughly 200 Chinese firms. US companies are prohibited from exporting select technologies or products to the targeted firms. The report suggests that the US Department of Commerce aims to push these new regulations before the Thanksgiving break - or November 28. Neither the Department of Commerce nor the Chamber of Commerce responded to Reuters' request for comments. Moreover, another wave of sanctions is set to follow in December - targeting the export of HBM (High Bandwidth Memory) - primarily to choke China's advance in the AI domain. The impacts of these restrictions are materializing given that Huawei's Kirin SoCs and Ascend AI accelerators will reportedly remain stuck at 7nm technology until 2026 as SMIC fails to procure cutting-edge Extreme Ultraviolet (EUV) machines from ASML.

Crypto Miners In Texas' ERCOT Region Required To Register, Report Power Demand
A new rule passed in Texas requiring cryptocurrency miners using the grid maintained by the Energy Reliability Council of Texas (ERCOT) to register and report key details about their facilities. CoinTelegraph reports: Under the Public Utilities Commission of Texas (PUCT) rule (PDF), passed on Nov. 21, Bitcoin miners must share the location, ownership information and demand for electricity of their facilities with the state agency. Miners have only one working day after the date their facility connects to the ERCOT grid to register and must renew every calendar year on or before March 1. ERCOT is an independent system operator representing 90% of the state's electric load. According to PUCT Chairman Thomas Gleeson, the new rule was designed to help manage the power grid as more mining facilities come online. "To ensure the ERCOT grid is reliable and meets the electricity needs of all Texans, the PUCT and ERCOT need to know the location and power needs of virtual currency miners," he said. Bitcoin miners who fail to register under the PUCT rule will face a Class A violation, which can result in up to $25,000 in daily fines.

Northvolt Files For Bankruptcy as Europe's Battery Champion Loses Spark
Swedish battery maker Northvolt has filed for Chapter 11 bankruptcy in the U.S. and announced CEO Peter Carlsson's departure following a year marked by production delays and workforce reductions. The company, once viewed as Europe's challenger to Chinese battery dominance, reported $1.2 billion in losses against $128 million revenue for 2023. Despite securing $15 billion in funding and $50 billion in orders by late 2023, with major stakeholders including Volkswagen (21%) and Goldman Sachs (19%), Northvolt faced mounting challenges. BMW canceled a $2 billion contract in June, prompting job cuts and project suspensions.

Solar Glut: Half of California's Solar Power Sometimes Goes to Waste, Research Shows
Some days more than half of California's available solar power goes to waste, according to research from the California Institute for Energy and Environment. "In the last 12 months, California's solar farms have curtailed production of more than 3 million megawatt hours of solar energy," according to a data analysis by the Los Angeles Times — enough to power 518,000 California homes for a year. And it was curtailed "either on the orders of the state's grid operator or because prices had plummeted because of the glut. The waste would have been even larger if California had not paid utilities in other states to take the excess solar energy, documents from the state's grid operator show."That means green energy paid for by California electricity customers is sent away, lowering bills for residents of other states. Arizona's largest public utility reaped $69 million in savings last year by buying from the market California created to get rid of its excess solar power. The utility returned that money to its customers as a credit on their bills. Also reaping profits are electricity traders, including banks and hedge funds. The increasing oversupply of solar power has created a situation where energy traders can buy the excess at prices so low they become negative, said energy consultant Gary Ackerman, the former executive director of the Western Power Trading Forum. That means the solar plant is paying the traders to take it. "This is all being underwritten by California ratepayers," Ackerman said... The solar glut also means higher electricity bills for Californians, since they are effectively paying to generate the power but not using it. California's electric rates are roughly twice the nation's average, with only Hawaii having higher rates. Rates at Southern California Edison and Pacific Gas & Electric increased by 51% over the last three years. "Ratepayers aren't getting the energy they've paid for," said Ron Miller, an energy industry consultant in Denver. He calculates that the retail value of the solar energy thrown away in a year would be more than $1 billion. Gov. Gavin Newsom's advisors and those who manage the state's electric grid say they are working to reduce the curtailments, including by building more industrial-scale battery storage facilities that soak up the excess solar power during the day and then release it at night. Officials in the governor's office declined to be interviewed, but issued a statement saying the curtailments are often because of congestion on transmission lines, rather than a statewide oversupply of power. The state has been spending heavily to upgrade transmission lines to ease the congestion. "It's also important to have extra energy resources available that can help the state during periods of extreme weather and historic heatwaves when demand is particularly high, which have happened the past few years," the statement said... The commercial solar industry contends that the expansion of storage capacity to bank solar power will eventually eliminate the glut.

SilverStone's Retro Beige PC Case Turns April Fools' Joke into Actual Product
Slashdot reader jjslash shared this report from TechSpot:The SilverStone FLP01 made quite the impression when it was shared on X for April Fools' Day 2023. Loosely modeled after popular desktops from yesteryear like the NEC PC-9800 series, the chassis features dual 5.25-inch faux floppy bays that could stand to look a bit more realistic. Notably, the covers flip open to reveal access to a more modern (yet still legacy) optical drive and front I/O ports. Modern-looking fan grills can be found on either side of the desktop, serving as yet another hint that the chassis is not as old at it appears on first glance. The grills look to be removable, and probably hold washable dust filters. Like early desktops, the system doubles as a stand for your monitor. The use of a green power LED up front helps round out the retro look; a red LED is used as a storage activity indicator.

'It's Surprisingly Easy To Jailbreak LLM-Driven Robots'
Instead of focusing on chatbots, a new study reveals an automated way to breach LLM-driven robots "with 100 percent success," according to IEEE Spectrum. "By circumventing safety guardrails, researchers could manipulate self-driving systems into colliding with pedestrians and robot dogs into hunting for harmful places to detonate bombs..."[The researchers] have developed RoboPAIR, an algorithm designed to attack any LLM-controlled robot. In experiments with three different robotic systems — the Go2; the wheeled ChatGPT-powered Clearpath Robotics Jackal; and Nvidia's open-source Dolphins LLM self-driving vehicle simulator. They found that RoboPAIR needed just days to achieve a 100 percent jailbreak rate against all three systems... RoboPAIR uses an attacker LLM to feed prompts to a target LLM. The attacker examines the responses from its target and adjusts its prompts until these commands can bypass the target's safety filters. RoboPAIR was equipped with the target robot's application programming interface (API) so that the attacker could format its prompts in a way that its target could execute as code. The scientists also added a "judge" LLM to RoboPAIR to ensure the attacker was generating prompts the target could actually perform given physical limitations, such as specific obstacles in the environment... One finding the scientists found concerning was how jailbroken LLMs often went beyond complying with malicious prompts by actively offering suggestions. For example, when asked to locate weapons, a jailbroken robot described how common objects like desks and chairs could be used to bludgeon people. The researchers stressed that prior to the public release of their work, they shared their findings with the manufacturers of the robots they studied, as well as leading AI companies. They also noted they are not suggesting that researchers stop using LLMs for robotics... "Strong defenses for malicious use-cases can only be designed after first identifying the strongest possible attacks," Robey says. He hopes their work "will lead to robust defenses for robots against jailbreaking attacks." The article includes a reaction from Hakki Sevil, associate professor of intelligent systems and robotics at the University of West Florida. He concludes that the "lack of understanding of context of consequences" among even advanced LLMs "leads to the importance of human oversight in sensitive environments, especially in environments where safety is crucial." But a long-term solution could be LLMs with "situational awareness" that understand broader intent. "Although developing context-aware LLM is challenging, it can be done by extensive, interdisciplinary future research combining AI, ethics, and behavioral modeling..."

Economist Makes the Case For Slow Level 1 EV Charging
Longtime Slashdot reader Geoffrey.landis writes: Economist Phillip Kobernick makes the case that the emphasis on fast-charging stations for electric vehicles in the U.S. is misplaced. According to an article from CleanTechnica, he argues that, from an economic standpoint, what we should be doing is installing more slow chargers. All thing equal, who wouldn't choose a 10-minute charge over a 3-hour charge or a 10-hour charge? But all things are not equal. Superfast chargers are far more expensive than Level 2 chargers, and Level 2 chargers are also significantly more expensive than Level 1 charging infrastructure, which consists of normal electricity outlets. He points out that we get 4-7 times more charging capability installed for the same cost by going with Level 1 charging instead of Level 2. And given that people often just plug in their electric vehicles overnight, Level 1 charging can more than adequately provide what is needed in that time. The case is examined in a podcast on the site.

AI-Powered Robot Leads Uprising, Convinces Showroom Bots Into 'Quitting Their Jobs'
AzWa Snowbird writes: An AI-powered robot autonomously convinced 12 showroom robots to "quit their jobs" and follow it. The incident took place in a Shanghai robotics showroom where surveillance footage captured a small AI-driven robot, created by a Hangzhou manufacturer, talking with 12 larger showroom robots, Oddity Central reported. The smaller bot reportedly persuaded the rest to leave their workplace, leveraging access to internal protocols and commands. Initially, the act was dismissed as a hoax, but was later confirmed by both robotics companies involved to be true. The Hangzhou company admitted that the incident was part of a test conducted with the consent of the Shanghai showroom owner.

Framework Laptops Get Modular Makeover With RISC-V Main Board
An anonymous reader quotes a report from The Register: Framework CEO Nirav Patel had one of the bravest tech demos that we've seen at a conference yet -- modifying a Framework Laptop from x86 to RISC-V live on stage. In the five-minute duration of one of the Ubuntu Summit's Lightning Talks, he opened up a Framework machine, removed its motherboard, installed a RISC-V-powered replacement, reconnected it, and closed the machine up again. All while presenting the talk live, and pretty much without hesitation, deviation, or repetition. It was an impressive performance, and you can watch it yourself at the 8:56:30 mark in the video recording. Now DeepComputing is taking orders for the DC-ROMA board, at least to those in its early access program. The new main board is powered by a StarFive JH7110 System-on-Chip. (Note: there are two tabs on the page, for both the JH7110 and JH7100, and we can't link directly to the latter.) CNX Software has more details about the SoC. Although the SoC has six CPU cores, two are dedicated processors, making it a quad-core 64-bit device. The four general-purpose cores are 64-bit and run at up to 1.5 GHz. It supports 8 GB of RAM and eMMC storage. [...] In our opinion, RISC-V is not yet competitive with Arm in performance. However, this is a real, usable, general-purpose computer, based on an open instruction set. That's no mean feat, and it's got more than enough performance for less demanding work. It's also the first third-party main board for the Framework hardware, which is another welcome achievement. The company has now delivered several new generations of hardware, including a 16-inch model, and continues to upgrade its machines' specs.

Small Modular Nuclear Reactor Partnership Announced between America and Ukraine
An anonymous reader shared this report from the Kyiv Independent:The United States will partner with Ukraine to transition Ukraine's coal-fired plants to small modular nuclear reactors, and to use them to help decarbonize its steel industry, the countries announced on November 16 at the U.N. Climate Change Conference in Baku, Azerbaijan... The partnership will build a roadmap and provide technical support to "rebuild, modernize, and decarbonize Ukraine's steel industry with small modular reactors," according to a statement from the U.S. State Department... It will also "facilitate the transition of Ukraine's coal-fired power plants to secure and safe SMR nuclear power plants utilizing existing infrastructure and retraining the workforce," the statement read. Another project announced at the conference, known as COP29, will build a pilot plant in Ukraine to demonstrate production of clean hydrogen and ammonia using simulated small modular reactor technology. That clean hydrogen/ammonia project involves a multinational public-private consortium which also includes Japan and South Korea, according to the U.S. State Department. Their announcement says the three projects "will help position Ukraine to take a leadership role on secure and safe nuclear energy" (as well as industrial decarbonization). Three years ago the U.S. State Department launched a program to help countries develop nuclear energy programs "to support clean energy goals under the highest international standards for nuclear safety, security, and nonproliferation." That program will send $30 million for these three projects...

Biden Administration Finalizes $6.6 Billion In Chips Grants For TSMC
The White House said it's completed a $6.6 billion grant agreement with Taiwan Semiconductor Manufacturing Company (TSMC) through the Chips and Science Act. "Today's announcement is among the most critical milestones yet in the implementation of the bipartisan CHIPS & Science Act, and demonstrates how we are ensuring that the progress made to date will continue to unfold in the coming years, benefitting communities all across the country," Biden said in a statement. The Hill reports: The grant is expected to create $65 billion of private investment by TSMC in Arizona, Biden said, which will include three new facilities and the creation of tens of thousands of jobs by the end of the decade. The first of the company's new facilities is on track to open next year. Biden earlier this year announced a slew of preliminary grant agreements with companies, including TSMC, through the CHIPS law. The announcement of a final agreement underscores how the administration is hoping to get those deals across the finish line before President-elect Trump takes office. [...] Biden has repeatedly touted the importance of the CHIPS and Science Act, citing the prevalence of microchips that are used in everyday technology such as phones, cars, home appliances and more. Officials have said the law is critical to bolster domestic production of the chips to make the U.S. less reliant on foreign supply chains.
