An anonymous reader shared this report from CNBC: [T]he computing power of crypto mining generates a lot of heat, most which just ends up vented into the air. According to digital assets brokerage, K33, the bitcoin mining industry generates about 100 TWh of heat annually — enough to heat all of Finland.This energy waste within a very energy-intense industry is leading entrepreneurs to look for ways to repurpose the heat for homes, offices, or other locations, especially in colder weather months.

During a frigid snap earlier this year, The New York Times reviewed HeatTrio, a $900 space heater that also doubles as a bitcoin mining rig. Others use the heat from their own in-home cryptocurrency mining to spread warmth throughout their house. "I've seen bitcoin rigs running quietly in attics, with the heat they generate rerouted through the home's ventilation system to offset heating costs. It's a clever use of what would otherwise be wasted energy," said Jill Ford, CEO of Bitford Digital, a sustainable bitcoin mining company based in Dallas... "Same price as heating the house, but the perk is that you are mining bitcoin," Ford said...

The crypto-heated future may be unfolding in the town of Challis, Idaho, where Cade Peterson's company, Softwarm, is repurposing bitcoin heat to ward off the winter. Several shops and businesses in town are experimenting with Softwarm's rigs to mine and heat. At TC Car, Truck and RV Wash, Peterson says, the owner was spending $25 a day to heat his wash bays to melt snow and warm up the water. "Traditional heaters would consume energy with no returns. They installed bitcoin miners and it produces more money in bitcoin than it costs to run," Peterson said. Meanwhile, an industrial concrete company is offsetting its $1,000 a month bill to heat its 2,500-gallon water tank by heating it with bitcoin. Peterson has heated his own home for two-and-a-half years using bitcoin mining equipment and believes that heat will power almost everything in the future. "You will go to Home Depot in a few years and buy a water heater with a data port on it and your water will be heated with bitcoin," Peterson said.
Derek Mohr, clinical associate professor at the University of Rochester Simon School of Business, remains skeptical. Bitcoin mining is so specialized now that a home computer, or even network of home computers, would have almost zero chance of being helpful in mining a block of bitcoin, according to Mohr, with mining farms use of specialized chips that are created to mine bitcoin much faster than a home computer... "The bitcoin heat devices I have seen appear to be simple space heaters that use your own electricity to heat the room..."
CNBC also spoke to Andrew Sobko, founder of Argentum AI (which is building a marketplace for sharing computing power), who says the idea makes the most sense in larger settings. "We're working with partners who are already redirecting compute heat into building heating systems and even agricultural greenhouse warming. That's where the economics and environmental benefits make real sense. Instead of trying to move the heat physically, you move the compute closer to where that heat provides value."

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.

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.

"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 of the last two years or so, sales of battery electric vehicles, while continuing to grow, have posted lower year-over-year percentage growth rates than they had in years prior. EV sales used to grow at 50%+ per year, but for the last couple years, they have grown closer to ~25% per year. This alone is not particularly remarkable — it is inevitable that any growing product or category will show slower percentage growth rates as sales rise, particularly one that has been growing at such a fast rate for so long. In some recent years, we had even seen year-over-year doublings in EV market share (though one of those was 2020->2021, which was anomalous). To expect improvement at that level perpetually would be close to impossible — after 3 years of doubling market share from 2023's 18% number, EVs would account for more than 100% of the global automotive market, which cannot happen...

We have seen a global EV sales growth rate of 23% in the first 10 months of this year, according to a report just released by Rho Motion (recently acquired by Benchmark Mineral Intelligence). That includes a +32% bump in Europe, +22% bump in China, +4% in North America, and a big +48% bump in the "rest of the world." Notably, this 23% global growth rate is higher than last year's YTD growth rate, which was 22% at this time...

In covering these trends, some journalists have attempted to use the less-wrong phrase "slower growth," showing that EV sales are still growing, but at a lower percentage change than previously seen. But for the first ten months of this year, that isn't true — EV sales are up more in 2025 than in 2024 by a percentage basis. They are also up in raw sales numbers — in 2024, EV sales grew by a larger number than in 2023. And the same is true so far in 2025. Going back to 2023, 10.7 million EVs were sold globally in the first 10 months. Then in 2024, 13.3 million were sold, a difference of 2.6 million. And so far in 2025, 16.5 million EVs have sold, a difference of 3.2 million. Not only are the numbers getting bigger, but the growth in unit sales is getting bigger as well.
Even in America, the EV 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 are indeed up and plug-in hybrids, which have grown more slowly than gas-hybrids/BEVs, have also shown some growth lately. But gas-hybrid sales have not come at the cost of EV sales, rather at the cost of gas-only car sales.

Because that's just the thing: the number of gas-only vehicles being sold worldwide is a number that actually is falling. That number continues to go down year over year. Sales of new gas-powered cars are down by about a quarter from their peak in 2017, and show no signs of recovering... And yet, somehow, virtually every headline you read is about the "EV sales slump," rather than the "gas-car sales slump." The one you keep hearing about isn't happening, but the one you rarely hear about is happening... No matter what region of the world you're in, EV sales were up in the first 10 months of this year.

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.

"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.

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 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.

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.

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.

Should we leave space exploration to robots — or prioritize human spaceflight, making us a multiplanetary species?

Harvard professor Robin Wordsworth, who's researched the evolution and habitability of terrestrial-type planets, shares his thoughts: In space, as on Earth, industrial structures degrade with time, and a truly sustainable life support system must have the capability to rebuild and recycle them. We've only partially solved this problem on Earth, which is why industrial civilization is currently causing serious environmental damage. There are no inherent physical limitations to life in the solar system beyond Earth — both elemental building blocks and energy from the sun are abundant — but technological society, which developed as an outgrowth of the biosphere, cannot yet exist independently of it. The challenge of building and maintaining robust life-support systems for humans beyond Earth is a key reason why a machine-dominated approach to space exploration is so appealing...

However, it's notable that machines in space have not yet accomplished a basic task that biology performs continuously on Earth: acquiring raw materials and utilizing them for self-repair and growth. To many, this critical distinction is what separates living from non-living systems... The most advanced designs for self-assembling robots today begin with small subcomponents that must be manufactured separately beforehand. Overall, industrial technology remains Earth-centric in many important ways. Supply chains for electronic components are long and complex, and many raw materials are hard to source off-world... If we view the future expansion of life into space in a similar way as the emergence of complex life on land in the Paleozoic era, we can predict that new forms will emerge, shaped by their changed environment, while many historical characteristics will be preserved. For machine technology in the near term, evolution in a more life-like direction seems likely, with greater focus on regenerative parts and recycling, as well as increasingly sophisticated self-assembly capabilities. The inherent cost of transporting material out of Earth's gravity well will provide a particularly strong incentive for this to happen.

If building space habitats is hard and machine technology is gradually developing more life-like capabilities, does this mean we humans might as well remain Earth-bound forever? This feels hard to accept because exploration is an intrinsic part of the human spirit... To me, the eventual extension of the entire biosphere beyond Earth, rather than either just robots or humans surrounded by mechanical life-support systems, seems like the most interesting and inspiring future possibility. Initially, this could take the form of enclosed habitats capable of supporting closed-loop ecosystems, on the moon, Mars or water-rich asteroids, in the mold of Biosphere 2. Habitats would be manufactured industrially or grown organically from locally available materials. Over time, technological advances and adaptation, whether natural or guided, would allow the spread of life to an increasingly wide range of locations in the solar system.
The article ponders the benefits (and the history) of both approaches — with some fasincating insights along the way.

"If genuine alien life is out there somewhere, we'll have a much better chance of comprehending it once we have direct experience of sustaining life beyond our home planet."

"Quantum computing is still years away, but Nvidia just built the bridge that will bring it closer..." argues investment site The Motley Fool, "by linking today's fastest AI GPUs with early quantum processors..."

NVIDIA's new hybrid system strengthens communication at microsecond speeds — orders of magnitude faster than before — "allowing AI to stabilize and train quantum machines in real time, potentially pulling major breakthroughs years forward." CUDA-Q, Nvidia's open-source software layer, lets researchers choreograph that link — running AI models, quantum algorithms, and error-correction routines together as one system. That jump allows artificial intelligence to monitor [in real time]... For researchers, that means hundreds of new iterations where there used to be one — a genuine acceleration of discovery. It's the quiet kind of progress engineers love — invisible, but indispensable...

Its GPUs (graphics processing units) are already tuned for the dense, parallel calculations these explorations demand, making them the natural partner for any emerging quantum processor... Other companies chase better quantum hardware — superconducting, photonic, trapped-ion — but all of them need reliable coordination with the computing power we already have. By offering that link, Nvidia turns its GPU ecosystem into the operating environment of hybrid computing, the connective tissue between what exists now and what's coming next. And because the system is open, every new lab or start-up that connects strengthens Nvidia's position as the default hub for quantum experimentation...

There's also a defensive wisdom in this move. If quantum computing ever matures, it could threaten the same data center model that built Nvidia's empire. CEO Jensen Huang seems intent on making sure that, if the future shifts, Nvidia already sits at its center. By owning the bridge between today's technology and tomorrow's, the company ensures it earns relevance — and revenue — no matter which computing model dominates.
So Nvidia's move "isn't about building a quantum computer," the article argues, "it's about owning the bridge every quantum effort will need."

alternative_right shares a report from The Conversation: Countries around the world have been discussing the need to rein in climate change for three decades, yet global greenhouse gas emissions -- and global temperatures with them -- keep rising. When it seems like we're getting nowhere, it's useful to step back and examine the progress that has been made. Let's take a look at the United States, historically the world's largest greenhouse gas emitter. Over those three decades, the U.S. population soared by 28% and the economy, as measured by gross domestic product adjusted for inflation, more than doubled. Yet U.S. emissions from many of the activities that produce greenhouse gases -- transportation, industry, agriculture, heating and cooling of buildings -- have remained about the same over the past 30 years.

Transportation is a bit up; industry a bit down. And electricity, once the nation's largest source of greenhouse gas emissions, has seen its emissions drop significantly. Overall, the U.S. is still among the countries with the highest per capita emissions, so there's room for improvement, and its emissions (PDF) haven't fallen enough to put the country on track to meet its pledges under the 10-year-old Paris climate agreement. But U.S. emissions are down about 15% over the past 10 years. The report mentions how the U.S. managed to replace coal with cheaper, more efficient natural-gas plants while rapidly scaling wind, solar, and battery storage as their costs fell. At the same time, major gains in appliance, lighting, and building efficiency flattened per-capita power use. This also coincided with improved vehicle fuel economy that helped keep transportation emissions in check.

According to the Wall Street Journal, Ford executives are considering scrapping the electric version of the F-150 pickup truck as losses, supply setbacks, slow sales, and the arrival of a cheaper midsize EV truck undermine the business case for its full-size electric pickup. Reuters reports: Last month, a union official told Reuters that Ford was pausing production at the Dearborn, Michigan, plant that makes its F-150 Lightning electric pickup due to a fire at a supplier's aluminum factory. "We have good inventories of the F-150 Lightning and will bring Rouge Electric Vehicle Center back up at the right time, but don't have an exact date at this time," Ford said in a statement on Thursday.

The WSJ report added that General Motors executives have discussed discontinuing some electric trucks, citing people familiar with the matter. The Detroit three, which includes Ford, GM and Chrysler-parent Stellantis, have rolled back their ambitious plans for EVs in the United States, pivoting to their gasoline-powered models.

A curious engineer discovered that his iLife A11 smart vacuum was remotely "killed" after he blocked it from sending data to the manufacturer's servers. By reverse-engineering it with custom hardware and Python scripts, he managed to revive the device to run fully offline. Tom's Hardware reports: An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device. That's when he noticed it was constantly sending logs and telemetry data to the manufacturer -- something he hadn't consented to. The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after. After a lengthy investigation, he discovered that a remote kill command had been issued to his device.

He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again. After several rounds of back-and-forth, the service center probably got tired and just stopped accepting it, saying it was out of warranty. Because of this, he decided to disassemble the thing to determine what killed it and to see if he could get it working again. [...] So, why did the A11 work at the service center but refuse to run in his home? The technicians would reset the firmware on the smart vacuum, thus removing the kill code, and then connect it to an open network, making it run normally. But once it connected again to the network that had its telemetry servers blocked, it was bricked remotely because it couldn't communicate with the manufacturer's servers. Since he blocked the appliance's data collection capabilities, its maker decided to just kill it altogether.

"Someone -- or something -- had remotely issued a kill command," says Harishankar. "Whether it was intentional punishment or automated enforcement of 'compliance,' the result was the same: a consumer device had turned on its owner." In the end, the owner was able to run his vacuum fully locally without manufacturer control after all the tweaks he made. This helped him retake control of his data and make use of his $300 software-bricked smart device on his own terms. As for the rest of us who don't have the technical knowledge and time to follow his accomplishments, his advice is to "Never use your primary WiFi network for IoT devices" and to "Treat them as strangers in your home."

Longtime Slashdot reader hackingbear writes: South China Morning Post, citing Chinese state media, reported that an experimental reactor developed in the Gobi Desert by the Chinese Academy of Sciences' Shanghai Institute of Applied Physics has achieved thorium-to-uranium fuel conversion, paving the way for an almost endless supply of nuclear energy. It is the first time in the world that scientists have been able to acquire experimental data on thorium operations from inside a molten salt reactor according to a report by Science and Technology Daily. Thorium is much more abundant and accessible than uranium and has enormous energy potential. One mine tailings site in Inner Mongolia is estimated to hold enough of the element to power China entirely for more than 1,000 years.

At the heart of the breakthrough is a process known as in-core thorium-to-uranium conversion that transforms naturally occurring thorium-232 into uranium-233 -- a fissile isotope capable of sustaining nuclear chain reactions within the reactor itself. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. Thorium fuels therefore need a fissile material as a 'driver' so that a chain reaction (and thus supply of surplus neutrons) can be maintained. The only fissile driver options are U-233, U-235 or Pu-239. (None of these are easy to supply.) In the 1960s, the Oak Ridge National Laboratory (USA) designed and built a demonstration MSR using U-233, derived externally from thorium as the main fissile driver.

Longtime Slashdot reader dbialac shares a report from EL PAIS: For decades, the progress of electronics has followed a simple rule: smaller is better. Since the 1960s, each new generation of chips has packed more transistors into less space, fulfilling the famous Moore's Law. Formulated by Intel co-founder Gordon Moore in 1965, this law predicted that the number of transistors in an integrated circuit approximately doubles each year. But this race to the minuscule is reaching its physical limits. Now, an international team of scientists is proposing a solution as obvious as it is revolutionary: if we can't keep reducing the size of chips, let's build them up.

Xiaohang Li, a researcher at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, and his team have designed a chip with 41 vertical layers of semiconductors and insulating materials, approximately ten times higher than any previously manufactured chip. The work, recently published in the journal Nature Electronics, not only represents a technical milestone but also opens the door to a new generation of flexible, efficient, and sustainable electronic devices. "Having six or more layers of transistors stacked vertically allows us to increase circuit density without making the devices smaller laterally," Li explains. "With six layers, we can integrate 600% more logic functions in the same area than with a single layer, achieving higher performance and lower power consumption."

Australia's new "solar sharer" program will give households in NSW, south-east Queensland, and South Australia at least three hours of free solar power each day starting in 2026 -- even for those without rooftop panels. Other areas will potentially follow in 2027. The Guardian reports: The government said Australians could schedule appliances such as washing machines, dishwashers and air conditioners and charge electric vehicles and household batteries during this time. The solar sharer scheme would be implemented through a change to the default market offer that sets the maximum price retailers can charge customers for electricity in parts of the country. The climate change and energy minister, Chris Bowen, said the program would ensure "every last ray of sunshine was powering our homes" instead of some solar energy being wasted.

Australians have installed more than 4m solar systems and there is regularly cheap excess generation in the middle of the day. Part of the rationale for the program is that it could shift demand for electricity from peak times -- particularly early in the evening -- to when it is sunniest. This could help minimize peak electricity prices and reduce the need for network upgrades and intervention to ensure the power grid was stable.

Bruce66423 shares a report from the Los Angeles Times: The board of the Los Angeles Department of Water and Power on Tuesday approved a controversial plan to convert part of the city's largest natural gas-fired power plant into one that also can burn hydrogen. In a 3-0 vote, the DWP board signed off on the final environmental impact report for an $800-million modernization of Units 1 and 2 of the Scattergood Generating Station in Playa del Rey. The power plant dates to the late 1950s and both units are legally required to be shut down by the end of 2029. In their place, the DWP will install new combined-cycle turbines that are expected to operate on a mixture of natural gas and at least 30% hydrogen with the ultimate goal of running entirely on hydrogen as more supply becomes available.

The hydrogen burned at Scattergood is supposed to be green, meaning it is produced by splitting water molecules through a process called electrolysis. Hydrogen does not emit planet-warming carbon dioxide when it is burned, unlike natural gas. [...] Although burning hydrogen does not produce CO2, the high-temperature combustion process can emit nitrogen oxides, or NOx, a key component of smog. [...] [T]he approved plan contains no specifics about where the hydrogen will come from or how it will get to the site. "The green hydrogen that would supply the proposed project has not yet been identified," the environmental report says. Industry experts and officials said the project will help drive the necessary hydrogen production. "Burning hydrogen produced by 'excess' solar or wind power is a means of energy storage," adds Slashdot reader Bruce66423. "The hard question is whether it's the best solution to the storage problem given that other solutions appear to be emerging that would require less infrastructure investment (think pipes to move the hydrogen to the plant and tanks to store it for later use)."
