"The world's largest renewable energy and transmission project has received key approval from government officials," reports New Atlas.

Solar power from Australia will be carried 2,672 miles (4,300 kilometers) to Singapore over undersea cables in what's being called "the Australia-Asia Power Link project." Reuters reports that SunCable "aims to produce 6 gigawatts of electricity at a vast solar farm in Northern Australia and ship about a third of that to Singapore via undersea cable."

More from New Atlas: [The project] will start by constructing a mammoth solar farm in Australia's Northern Territory to transmit around-the-clock clean power to [the Australian city] Darwin, and also export "reliable, cost-competitive renewable energy" to Singapore... with a clean energy generation capacity of up to 10 gigawatts, plus utility scale onsite storage. [The recently-obtained environmental approval] also green lights an 800-km (~500-mile) overhead transmission line between the solar precinct and Murrumujuk near Darwin...

If all of the dominoes line up perfectly, supply of the first clean electricity is estimated to start in the early 2030s. An overview graphic on the project page shows that the eventual end game for the Powell Creek development appears to be the generation of up to 20 GW of peak solar power and have some 36-42 GWh of battery storage on site.

PV Magazine reports: Researchers in Australia and China have developed an innovative technology enabling direct lithium extraction from difficult-to-process sources like saltwater, which they say represents a substantial portion of the world's lithium potential.

Until now, up to 75% of the world's lithium-rich saltwater sources have remained untapped because of technical limitations, but given predictions that global lithium supply could fall short of demand as early as 2025, the researchers believe they have a game-changing solution. Their technology is a type of nanofiltration system that uses ethylenediaminetetraacetic acid, or EDTA, as a chelating agent to selectively separate lithium from other minerals, especially magnesium, which is often present in brines and difficult to remove.
"With some predicting global lithium supply could fall short of demand as early as 2025, the innovative technology sets a new standard in lithium processing," writes SciTechDaily: The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, promises to meet the surging demand for lithium and paves the way for more sustainable and efficient extraction practices... "Our technology achieves 90 percent lithium recovery, nearly double the performance of traditional methods, while dramatically reducing the time required for extraction from years to mere weeks," Dr. Li said.

The technology also turns leftover magnesium into a valuable, high-quality product that can be sold, reducing waste and its impact on the environment. Beyond its advanced efficiency, the EALNF system brings innovation to address major environmental concerns associated with lithium extraction. Unlike conventional methods that deplete vital water resources in arid regions, the technology produces freshwater as a by-product.

Dr Li said the system was flexible and ready for large-scale use, meaning it can quickly expand from testing to full industrial operations. "This breakthrough is crucial for avoiding a future lithium shortage, making it possible to access lithium from hard-to-reach sources and helping power the shift to clean energy."
"Our scalable process minimizes environmental impact while maximizing resource utilization," according to the researchers' article in Nature Sustainability, "thereby catalysing the shift toward a more sustainable future."

Longtime Slashdot reader Baron_Yam writes: Memristors are the long-sought 4th fundamental circuit element. They promise analog computing capability in hardware, the ability to hold state without power, and to work with less power. A small cluster of them can replace a transistor using less space. Working and long term storage can blend together and neural networks can be implemented in hardware -- they are a game-changing innovation. Now, researchers are getting closer to putting these into production as they can now produce graphene-based memristors at wafer scale. "One of the key challenges in memristor development is device degradation, which graphene can help prevent," reports Phys.Org. "By blocking chemical pathways that degrade traditional electrodes, graphene could significantly extend the lifetime and reliability of these devices. Its remarkable transparency, transmitting 98% of light, also opens doors to advanced computing applications, particularly in AI and optoelectronics."

The findings have been published in the journal ACS Advanced Electronic Materials.

MojoKid writes: Intel has lifted the embargo on independent reviews of its new Core Ultra 200S series Arrow Lake-S processors, which mark a shift in its desktop CPU strategy with symmetrical core/thread counts (no Hyperthreading) and a dedicated 13 TOPS NPU. This series features a disaggregated tiled design for the first time in Intel's desktop chips, focusing on efficiency and power reduction. The Core Ultra 5 245, priced around $300, and the Ultra 9 285K at $589 deliver strong performance, particularly in creator workloads, competing well with AMD's Ryzen CPUs, while the Ultra 9 285K's price undercuts AMD's Ryzen 9 9950X significantly. While gaming performance shows slight regression in spots, the new chips are much more power-efficient than their predecessors. Overall, the platform offers leading-edge features, competitive pricing, and solid performance for creators, gamers and workstation pros.

whitroth writes: People here and elsewhere have been yelling for more nuclear power, and that renewables can't meet demand. Surprise -- the corporations are betting on them, and massive numbers of batteries can be produced a lot faster than nuclear plants can be built. The Guardian adds: Faced with worsening climate-driven disasters and an electricity grid increasingly supplied by intermittent renewables, the US is rapidly installing huge batteries that are already starting to help prevent power blackouts. From barely anything just a few years ago, the US is now adding utility-scale batteries at a dizzying pace, having installed more than 20 gigawatts of battery capacity to the electric grid, with 5GW of this occurring just in the first seven months of this year, according to the federal Energy Information Administration (EIA). This means that battery storage equivalent to the output of 20 nuclear reactors has been bolted on to America's electric grids in barely four years, with the EIA predicting this capacity could double again to 40GW by 2025 if further planned expansions occur.

California and Texas, which both saw all-time highs in battery-discharged grid power this month, are leading the way in this growth, with hulking batteries helping manage the large amount of clean yet intermittent solar and wind energy these states have added in recent years.

AmiMoJo shares a report from Live Science: Scientists have demonstrated a new humanoid robot that can run at a top speed of just over 8 miles per hour (mph) -- or 3.6 meters per second (m/s) to be exact. This makes it the speediest machine of its kind built so far, albeit these speeds were only achieved with the help of added footwear. STAR1 is a bipedal robot built by the Chinese company Robot Era that's 5 feet 7 inches (171 centimeters) tall and weighs 143 pounds (65 kilograms).

Powered by high-torque motors and artificial intelligence (AI) algorithms, the footwear-donning STAR1 navigated different types of terrain, including grassland and gravel, while jogging on paved roads and earth, and sustained its top speed for 34 minutes. A top speed of 8 mph means it beat Unitree's H1 robot -- which set the previous speed record for a bipedal robot at 7.4 mph (3.3 m/s) in March 2024. Although STAR1 had the help of footwear, H1 was not technically jogging or running as its feet did not both leave the ground at once during transit. You can watch STAR1 racing through the Gobi Desert here.

San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement.

While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.

An anonymous reader quotes a report from Ars Technica: Qualcomm has a new chip for flagship phones, and the best part is that it uses an improved version of the Oryon CPU architecture that the Snapdragon X Elite chips brought to Windows PCs earlier this year. The Snapdragon 8 Elite is the follow-up to last year's Snapdragon 8 Gen 3 -- yet another change to the naming convention that Qualcomm uses for its high-end phone chips, though, as usual, the number 8 is still involved. The 8 Elite uses a "brand-new, 2nd-generation Qualcomm Oryon CPU" with clock speeds up to 4.32 GHz, which Qualcomm says will improve performance by about 45 percent compared to the Snapdragon 8 Gen 3.

Rather than a mix of large, medium, and small CPU cores as it has used in the past, the 8 Elite has two "Prime" cores for hitting that high peak clock speed, while the other six are all "Performance" cores that peak at a lower 3.53 GHz. But it doesn't look like Qualcomm is using a mix of different CPU architectures anymore, choosing to distinguish the higher-performing core from the lower-performing ones by clock speed alone. Qualcomm promises a similar 40 percent performance boost from the new Adreno 830 GPU. The chip also includes a marginally improved Snapdragon X80 5G modem, up from an X75 modem in the Snapdragon 8 Gen 3 -- its main improvement appears to be support for additional antennas, for a total of six, but the download speed still tops out at a theoretical 10Gbps. Wi-Fi 7 support appears to be the same as in the 8 Gen 3, but the 8 Elite does support the Bluetooth 6.0 standard, up from Bluetooth 5.4 in the 8 Gen 3.

Qualcomm says the new chip's CPU features "44% improved power efficiency" and "40% greater power efficiency" for the GPU, which ought to keep power usage in line despite the performance improvements -- these gains are probably attributable to the new 3 nm TSMC manufacturing process, compared to the 4 nm process used for the Snapdragon 8 Gen 3. And no 2024 chip announcement would be complete without some kind of AI mention: Qualcomm's image signal processor is now an "AI ISP," which Qualcomm says "recognizes and enhances virtually anything in the frame, including faces, hair, clothing, objects, backgrounds, and beyond." These capabilities can allow it to remove objects from the background of photos, among other things, using the on-device processing power of the chip's Hexagon neural processing unit (NPU). The NPU is 45 percent faster than the one in the Snapdragon 8 Gen 3. Phones using the Snapdragon 8 Elite should begin appearing in "the coming weeks."

In a new teardown video published last week, iFixit reveals a Quest 2 headset "hiding inside" the cheaper yet enhanced Quest 3S. The Verge reports: The first hint of that is the headset's Fresnel lenses, which iFixit's Shahram Mokhtari writes in a blog post are "100% compatible" with those used by the Quest 2. The headset has the older headset's IPD adjustment mechanism, as well; and it shares the same single LCD panel, rather than using one panel per eye, like the Meta Quest 3.

Legacy parts aside, iFixit found that the 3S uses two IR sensors for depth mapping instead of a single depth sensor. That "rare iterative improvement over the Quest 3" performed "exceptionally well in unlit spaces," Mokhtari writes in the blog. And of course, it uses the same Qualcomm Snapdragon XR2 SoC as the Quest 3, and works with Meta's newer Touch Plus controllers, which are sold separately. The Quest 3S "costs $299.99, while the Quest 3 is $499.99," notes The Verge. So, not only is the 3S cheaper but replacement parts should be easier to find since the Quest 2 "has already been around for four years."

Researchers at the United States Geological Survey and the Arkansas government announced on Monday that they had found a trove of lithium, a critical raw material for electric vehicle batteries, in an underground brine reservoir in Arkansas. From a report: With the help of water testing and machine learning, the researchers determined that there might be five million to 19 million tons of lithium -- more than enough to meet all of the world's demand for the metal -- in a geological area known as the Smackover Formation. Several companies, including Exxon Mobil, are developing projects in Arkansas to produce lithium, which is dissolved in underground brine.

Energy and mining companies have long produced oil, gas and other natural resources in the Smackover, which extends from Texas to Florida. And the federal and state researchers said lithium could be extracted from the waste stream of the brines from which companies extracted other forms of energy and elements. The energy industry, with the Biden administration's encouragement, has been increasingly working to produce the raw materials needed for the lithium-ion batteries in the United States. A few projects have started recently, and many more are in various stages of study and development across the country.

Most of the world's lithium is produced in Australia and South America. A large majority of it is then processed in China, which also dominates the manufacturing of electric vehicle batteries. "The potential for increased U.S. production to replace imports has implications for employment, manufacturing and supply chain resilience," David Applegate, the director of the United States Geological Survey, said in a statement announcing the study. "This study illustrates the value of science in addressing economically important issues."

"Several of Europe's biggest carmakers unveiled low-cost electric vehicles at the Paris Motor Show this week," reports CNBC. The automakers are "seeking to jump-start a demand slump and recapture some of the market share now held by Chinese brands." "It feels like Europe is fighting back," Julia Poliscanova, senior director for vehicles and e-mobility supply chains at the Transport & Environment campaign group, told CNBC at the Paris Motor Show. "There are so many new models on show, and what is really great is that there are a lot of launches that are more affordable. So, Citroen, Peugeot [and] Renault, they are all showing some smaller affordable models," Poliscanova said. "This is exactly what we need for the mass market, for people to buy those vehicles more, and this is also where the competition from the Chinese is also the hardest," she added...

"The storytelling is that people have cooled off on EVs and there is no consumer demand, [but] this is really not true," Transport & Environment's Poliscanova said. "This year in Europe, we did not have affordable models, so people are not buying those overpriced premium vehicles. However, as soon as vehicles come in the right price range next year ... people will flock to buy them." Poliscanova said the launch of several low-cost EVs means electric car sales could account for up to a 24% market share next year, up from 14% this year. Chinese-made EVs typically cost less than half the prices seen in Europe and the U.S. last year, according to figures published by data firm JATO, underscoring the challenge for Western automakers to keep pace with Beijing...

Pere Brugal, president and managing director of GM Europe, said that the challenges facing Europe's auto industry should be seen as a transitional phase — and not evidence of a crisis. "The adoption of new technologies and new behaviors is never a linear growth story, but the end is full-electric [vehicles]," Brugal told CNBC at the Paris Motor Show.
Meanwhile, GM's CEO "says it will start making money on battery-powered models by the end of the year — becoming the only U.S. automaker aside from Tesla to achieve that feat," reports the New York Times (adding that sales are increasing "and the company just introduced a model that sells for less than $30,000 after a federal tax credit.")

And GM "is still committed to doing away with combustion engine cars in the United States by 2035."

"Millions of Cubans remained without power for a third day in a row Sunday," reports CNN, "after fresh attempts to restore electricity failed overnight and the power grid collapsed for the fourth time — all before the arrival of Hurricane Oscar."

A report from Reuters notes it was the fourth power grid failure in 48 hours. "On the forecast track, the center of Oscar is expected to continue moving across eastern Cuba tonight and Monday, then emerge off the northern coast of Cuba late Monday and cross the central Bahamas on Tuesday," the U.S. National Hurricane Center said. The Communist-run government canceled school through Wednesday — a near unprecedented move in Cuba — citing the hurricane and the ongoing energy crisis...

Cuba had restored power to 160,000 clients in Havana just prior to the grid's Sunday collapse, giving some residents a glimmer of hope... Energy and mines minister Vicente de la O Levy told reporters earlier on Sunday he expected the grid to be fully functional by Monday or Tuesday but warned residents not to expect dramatic improvements.

It was not immediately clear how much the latest setback would delay the government's efforts.

That massive geothermal energy project in Utah gets a closer look from the Washington Post, which calls it "a significant advance for a climate-friendly technology that is gaining momentum in the United States." Once fully operational, the project could generate up to 2 gigawatts of electricity — enough to power more than 2 million homes. In addition, the BLM proposed Thursday to speed up the permitting process for geothermal projects on public lands across the country. Earlier this month, the agency also hosted the biggest lease sale for geothermal developers in more than 15 years...

White House national climate adviser Ali Zaidi said in an interview Thursday, "Enhanced geothermal technology has the opportunity to deliver something in the range of 65 million homes' worth of clean power — power that can be generated without putting any pollution in the sky. So we see it as a really meaningful contributor to our technology tool kit...."

The developments Thursday come as tech companies race to find new sources of zero-emission power for data centers that can use as much energy as entire cities. With major backing from Google parent Alphabet, Fervo recently got its first project up and running in the northern Nevada desert... The advanced geothermal technology that Fervo is trying to scale up is an attractive option for tech firms. Enhanced geothermal plants do not pose all the safety concerns that come with nuclear power, but they have the potential to provide the round-the-clock energy that data centers need. The challenge Fervo faces is whether it can bring this technology online quickly enough.
Fervo (a seven-year-old start-up) was co-founded by Tim Latimer, who previously worked as a drilling engineer, according to the article. But "Early in my career I got passionate about climate change. I started looking at where could a drilling engineer from the oil and gas industry make a difference," Latimer said during a Washington Post Live event in September. "And I realized that geothermal had been so overlooked ... even though the primary technical challenge to making geothermal work is dropping drilling costs."

"A technology pioneered by Benjamin Franklin is being revived to build more efficient electric motors," reports the Wall Street Journal, "an effort in its nascent stage that has the potential to be massive." A handful of scientists and engineers — armed with materials and techniques unimaginable in the 1700s — are creating modern versions of Franklin's "electrostatic motor," that are on the cusp of commercialization... Franklin's "electrostatic motor" uses alternating positive and negative charges — the same kind that make your socks stick together after they come out of the dryer — to spin an axle, and doesn't rely on a flow of current like conventional electric motors. Every few years, an eager Ph.D. student or engineer rediscovers this historical curiosity. But other than applications in tiny pumps and actuators etched on microchips, where this technology has been in use for decades, their work hasn't made it out of the lab.

Electrostatic motors have several potentially huge advantages over regular motors. They are up to 80% more efficient than conventional motors after all the dependencies of regular electric motors are added in. They could also allow new kinds of control and precision in robots, where they could function more like our muscles. And they don't use rare-earth elements because they don't have permanent magnets, and require as little as 5% as much copper as a conventional motor. Both materials have become increasingly scarce and expensive over the past decade, and supply chains for them are dominated by China.
"It's reminiscent of the early 1990s, when Sony began to produce and sell the first rechargeable lithium-ion batteries, a breakthrough that's now ubiquitous..." according to the article. "These motors could lead to more efficient air-conditioning systems, factories, logistics hubs and data centers, and — since they can double as generators — better ways of generating renewable energy. They might even show up in tiny surveillance drones."

And the article points out that C-Motive Technologies, a 16-person startup in Wisconsin, is already "reaching out to companies, hoping to get their motors out into the real world." ("So far, FedEx and Rockwell Automation, the century-old supplier of automation to factories, are among those testing their motors.") C-Motive's founders discovered that a number of technologies had matured enough that, when combined, could yield electrostatic motors competitive with conventional ones. These enabling technologies include super fast-switching power electronics — like those in modern electric vehicles — that can toggle elements of the motor between states of positive and negative charge very quickly... Dogged exploration of combinations of various readily available industrial organic fluids led to a proprietary mix that can both multiply the strength of the electric field and insulate the motor's spinning parts from each other — all without adding too much friction — says C-Motive Chief Executive Matt Maroon.
