Scientists Create Programmable, Autonomous Robots Smaller Than a Grain of Salt (upenn.edu) 46

Researchers at the University of Pennsylvania and University of Michigan "have created the world's smallest fully programmable, autonomous robots," according to a recent announcement.

The announcement calls them "microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each." Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices. Powered by light, the robots carry microscopic computers and can be programmed to move in complex patterns, sense local temperatures and adjust their paths accordingly... "We've made autonomous robots 10,000 times smaller," says Marc Miskin, Assistant Professor in Electrical and Systems Engineering at Penn Engineering and the papers' senior author. "That opens up an entirely new scale for programmable robots."
The announcement describes them as "the first truly autonomous, programmable robots at this scale" (as described in two recent academic articles). The team had to design a new propulsion system that utilized the unique locomotion physics in the microscopic realm, according to the university's announcement. So the robots "generate an electrical field that nudges ions in the surrounding solution." Those ions, in turn, push on nearby water molecules, animating the water around the robot's body. "It's as if the robot is in a moving river," says Miskin, "but the robot is also causing the river to move." The robots can adjust the electrical field that causes the effect, allowing them to move in complex patterns and even travel in coordinated groups, much like a school of fish, at speeds of up to one body length per second...

To be truly autonomous, a robot needs a computer to make decisions, electronics to sense its surroundings and control its propulsion, and tiny solar panels to power everything, and all that needs to fit on a chip that is a fraction of a millimeter in size. This is where David Blaauw's team at the University of Michigan came into action... The robots are programmed by pulses of light that also power them. Each robot has a unique address that allows the researchers to load different programs on each robot. "This opens up a host of possibilities," adds Blaauw, "with each robot potentially performing a different role in a larger, joint task."

99% of New US Energy Capacity Will Be Green in 2026 (electrek.co) 71

This year in America, renewables and battery storage "will account for 99.2% of net new capacity — and even higher if small-scale solar were included," reports Electrek, citing EIA data reviewed by the SUN DAY Campaign: EIA's latest monthly "Electric Power Monthly" report (with data through November 30, 2025), once again confirms that solar is the fastest-growing among the major sources of US electricity... [U]tility-scale solar thermal and photovoltaic expanded by 34.5% while that from small-scale systems rose by 11.3% during the first 11 months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 28.1% and produced a bit under 9.0% (utility-scale: 6.74%; small-scale: 2.13%) of total US electrical generation for January to November, up from 7.1% a year earlier.

Wind turbines across the US produced 10.1% of US electricity in the first 11 months of 2025 — an increase of 1.2% compared to the same period in 2024. In November alone, wind-generated electricity was 2.0% greater than a year earlier... The mix of all renewables (wind, solar, hydropower, biomass, and geothermal) produced 8.7% more electricity in January-November than a year earlier and accounted for 25.7% of total US electricity production, up from 24.3% 12 months earlier. Renewables' share of electrical generation is now second to only that of natural gas, whose electrical output actually dropped by 3.7% during the first 11 months of 2025...

Since January 1 to November 30, roughly the beginning of the Trump administration, renewable energy capacity, including battery storage, small-scale solar, hydropower, geothermal, and biomass, ballooned by 45,198.1 MW, while all fossil fuels and nuclear power combined declined by 519.2 MW...

[In 2026] natural gas capacity will increase by only 3,960.7 MW, which will be almost completely offset by a decrease of 3,387.0 MW in coal capacity.

Nvidia CEO Denies OpenAI's $100B Investment from Nvidia is 'Stalled' (msn.com) 19

Saturday Nvidia CEO Jensen Huang said they still planned a "huge" investment in OpenAI, according to CNBC.

Friday the Wall Street Journal had reported that Nvidia's plan to invest up to $100 billion in OpenAI "has stalled after some inside the chip giant expressed doubts about the deal, people familiar with the matter said..." [T]he talks haven't progressed beyond the early stages, some of the people said. Now, the two sides are rethinking the future of their partnership, some of the people said. The latest discussions, they said, include an equity investment of tens of billions of dollars as part of OpenAI's current funding round. Nvidia CEO Jensen Huang has privately emphasized to industry associates in recent months that the original $100 billion agreement was nonbinding and not finalized, people familiar with the matter said. He has also privately criticized what he has described as a lack of discipline in OpenAI's business approach and expressed concern about the competition it faces from the likes of Google and Anthropic, some of the people said...

OpenAI is laying the foundation to go public by the end of 2026, and has spent much of the past year racing to secure large amounts of computing capacity to help power OpenAI's future products and growth. The stalled Nvidia pact is a blow to this effort and shows how Chief Executive Sam Altman's penchant for announcing flashy big-ticket deals carries the potential to backfire if the terms have yet to be finalized. In a joint announcement unveiling the September deal with Altman and OpenAI President Greg Brockman, Huang called the deal "the largest computing project in history...." OpenAI went on to sign a string of other agreements with chip and cloud companies that helped fuel a global stock market rally.

But investors have since grown jittery about the startup's ability to pay for these deals, leading to a sell-off in some tech stocks tied to OpenAI. Altman has said that the deals put the startup on the hook for $1.4 trillion in computing commitments — more than 100 times the revenue it was on pace to generate last year. OpenAI executives say the total commitments are lower when you account for overlap in some of the deals, and that the agreements will take place over a long period of time.... Huang has indicated to associates that he still believes it's crucially important to provide OpenAI with financial support in one form or another, in part because OpenAI is one of the chip designer's largest customers, people familiar with the matter said. If OpenAI were to fall behind other AI developers, it could dent Nvidia's sales.

"Speaking to reporters in Taipei, Huang said it was 'nonsense' to say he was unhappy with OpenAI," CNBC reported Saturday: "We are going to make a huge investment in OpenAI. I believe in OpenAI, the work that they do is incredible, they are one of the most consequential companies of our time and I really love working with Sam," he said, referring to OpenAI CEO Sam Altman. "Sam is closing the round (of investment) and we will absolutely be involved," Huang added. "We will invest a great deal of money, probably the largest investment we've ever made."

Asked whether it would be over $100 billion, he said: "No, no, nothing like that."

Elsewhere the Journal has reported that Amazon is in talks to invest up to $50 billion in OpenAI. Thanks to Slashdot reader sinij for sharing the article.

'Reverse Solar Panel' Generates Electricity at Night (extremetech.com) 34

Researchers at the University of New South Wales are developing a "reverse solar panel" that generates small amounts of electricity at night by harvesting infrared heat radiated from Earth. "In the past, scientists have demonstrated that a 'thermoradiative diode' can convert infrared radiation directly into electricity; when used to convert heat from Earth, they exploit the temperature difference between Earth and the night sky, generating a current directly from heat," notes ExtremeTech. "This approach completely eliminates the need for heat to generate steam, though the resulting capacity is fairly low." From the report: The researchers estimate they could generate only about a watt per square meter, which isn't much. One reason for the low output is that the Earth's atmosphere lessens the heat differential that drives the generative process; in space, though, that's not an issue.

Now, researchers believe that the ability to generate power in the moments between direct sunlight could help power satellites. That could be especially true in deep space, where periods without sunlight can be longer, and sunlight is often weaker; in these situations, losing electricity to heat loss is unacceptable.

Many satellites already use heat to generate electricity, though with a much more rarified "thermoelectric generator" that uses rare, expensive materials like plutonium to create heat. With thermoradiative diodes, the heat source can be the Sun-warmed body of the satellite itself.

UK's First Rapid-Charging Battery Train Ready For Boarding (theguardian.com) 72

An anonymous reader quotes a report from the Guardian: The UK's first superfast-charging train running only on battery power will come into passenger service this weekend -- operating a five-mile return route in west London. Great Western Railway (GWR) will send the converted London Underground train out from 5.30am to cover the full Saturday timetable on the West Ealing to Greenford branch line, four stops and 12 minutes each way, and now carrying up to 273 passengers, should its celebrity stoke up the demand.

The battery will recharge in just three and a half minutes back at West Ealing station between trips, using a 2,000kW charger connected to a few meters of rail that only becomes live when the train stops directly overhead. There are hopes within government and industry that this technology could one day replace diesel trains on routes that have proved difficult or expensive to electrify with overhead wires, as the decarbonization of rail continues.

The train has proved itself capable of going more than 200 miles on a single charge -- last year setting a world record for the farthest travelled by a battery-electric train, smashing a German record set in 2021. The GWR train and the fast-charge technology has been trialled on the 2.5-mile line since early 2024, but has not yet carried paying passengers.

Los Angeles Aims To Ban Single-Use Printer Cartridges (tomshardware.com) 71

Los Angeles is moving to ban single-use printer cartridges that can't be refilled or taken back for recycling. Tom's Hardware reports: Printer cartridges are usually built with a combination of plastic, metal, and chemicals that makes them hard to easily dispose. They can be treated as hazardous waste by the city, but even then it would take them hundreds of years to actually disintegrate at a waste site. Since they're designed to be thrown away in the first place, the real solution is to target the root of the issue -- hence the ban.

Fully Electric Vehicle Sales In EU Overtake Petrol For First Time In December (yahoo.com) 92

Longtime Slashdot reader AmiMoJo shares a report from Reuters: Fully electric car sales in December overtook petrol for the first time in the European Union, even as policymakers proposed to loosen emissions regulations, data showed on Tuesday. U.S. battery-electric brand Tesla continued to lose market share to competitors including China's BYD and Europe's best-selling group Volkswagen, data from the European auto lobby ACEA showed.

Car sales throughout Europe sustained a sixth straight month of year-on-year growth, with overall registrations, a proxy for sales, hitting their highest volumes in five years in Europe in 2025, though they remained well below pre-pandemic levels. [...] December registrations of battery electric, plug-in hybrid and hybrid electric cars were up 51%, 36.7% and 5.8%, respectively, to account collectively for 67% of the bloc's registrations, up from 57.8% in December 2024.

Microsoft's Latest AI Chip Claims Performance Edge Over Amazon and Google (geekwire.com) 18

An anonymous reader quotes a report from GeekWire: Microsoft on Monday announced Maia 200, the second generation of its custom AI chip, claiming it's the most powerful first-party silicon from any major cloud provider. The company says Maia 200 delivers three times the performance of Amazon's latest Trainium chip on certain benchmarks, and exceeds Google's most recent tensor processing unit (TPU) on others. The chip is already running workloads at Microsoft's data center near Des Moines, Iowa. Microsoft says Maia 200 is powering OpenAI's GPT-5.2 models, Microsoft 365 Copilot, and internal projects from its Superintelligence team. A second deployment at a data center near Phoenix is planned next.

It's part of the larger trend among cloud giants to build their own custom silicon for AI rather than rely solely on Nvidia. [...] The company says Maia 200 offers 30% better performance-per-dollar than its current hardware. Maia 200 also builds on the first-generation chip with a more specific focus on inference, the process of running AI models after they've been trained. [...] Microsoft is also opening the door to outside developers. The company announced a software development kit that will let AI startups and researchers optimize their models for Maia 200. Developers and academics can sign up for an early preview starting today.

Startup Uses SpaceX Tech to Cool Data Centers With Less Power and No Water (yahoo.com) 56

California-based Karman Industries "says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers," reports the Los Angeles Times, "chilling them with less space, less power and no water." Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company's efficient pumps can reduce the space required for data center cooling equipment by 80%.

Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat. A 50 megawatt data center also uses enough electricity to power a mid-sized city... Cooling systems account for up to 40% of a data center's power consumption and an average midsized data center consumes more than 35,000 gallons of water per day...

U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency... The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year... To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat...

About a third of Karman's 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors. The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy. Karman's heat pump can either reject heat to air, or route it into extra cooling, or even power generation.

The company "recently raised $20 million," according to the article, "and expects to start building its first compressors in Long Beach later this year...."

Washington State May Mandate 'Firearm Blueprint Detection Algorithms' For 3D Printers (adafruit.com) 123

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) writes: Washington State lawmakers are proposing bills (HB 2320 and HB 2321) that would require 3D printers and CNC machines to block certain designs using software-based "firearms blueprint detection algorithms." In practice, this means scanning every print file, comparing it against a government-maintained database, and preventing "skilled users" from bypassing the system.

Supporters frame this as a response to untraceable "ghost guns," but even federal prosecutors admit the tools involved are ordinary manufacturing equipment. Critics warn the language is overbroad, technically unworkable, hostile to open source, and likely to push printing toward cloud-locked, subscription-based systems—while doing little to stop criminals.

Gasoline Out of Thin Air? It's a Reality! (jalopnik.com) 122

Can Aircela's machine "create gasoline using little more than electricity and the air that we breathe"? Jalopnik reports... The Aircela machine works through a three-step process. It captures carbon dioxide directly from the air... The machine also traps water vapor, and uses electrolysis to break water down into hydrogen and oxygen... The oxygen is released, leaving hydrogen and carbon dioxide, the building blocks of hydrocarbons. This mixture then undergoes a process known as direct hydrogenation of carbon dioxide to methanol, as documented in scientific papers.

Methanol is a useful, though dangerous, racing fuel, but the engine under your hood won't run on it, so it must be converted to gasoline. ExxonMobil has been studying the process of doing exactly that since at least the 1970s. It's another well-established process, and the final step the Aircela machine performs before dispensing it through a built-in ordinary gas pump. So while creating gasoline out of thin air sounds like something only a wizard alchemist in Dungeons & Dragons can do, each step of this process is grounded in science, and combining the steps in this manner means it can, and does, really work.

Aircela does not, however, promise free gasoline for all. There are some limitations to this process. A machine the size of Aircela's produces just one gallon of gas per day... The machine can store up to 17 gallons, according to Popular Science, so if you don't drive very much, you can fill up your tank, eventually... While the Aircela website does not list a price for the machine, The Autopian reports it's targeting a price between $15,000 and $20,000, with hopes of dropping the price once mass production begins. While certainly less expensive than a traditional gas station, it's still a bit of an investment to begin producing your own fuel. If you live or work out in the middle of nowhere, however, it could be close to or less than the cost of bringing gas to you, or driving all your vehicles into a distant town to fill up. You're also not limited to buying just one machine, as the system is designed to scale up to produce as much fuel as you need.

The main reason why this process isn't "something for nothing" is that it takes twice as much electrical energy to produce energy in the form of gasoline. As Aircela told The Autopian " Aircela is targeting >50% end to end power efficiency. Since there is about 37kWh of energy in a gallon of gasoline we will require about 75kWh to make it. When we power our machines with standalone, off-grid, photovoltaic panels this will correspond to less than $1.50/gallon in energy cost."

The Case Against Small Modular Nuclear Reactors (cnn.com) 146

Small modular nuclear reactors (or SMRs) are touted as "cheaper, safer, faster to build and easier to finance" than conventional nuclear reactors, reports CNN. Amazon has invested in X-Energy, and earlier this month, Meta announced a deal with Oklo, and in Michigan last month, Holtec began the long formal licensing process for two SMRs with America's Nuclear Regulatory Commission next to a nuclear plant it hopes to reactive. (And in 2024, California-based Kairos Power broke ground in Tennessee on a SMR "demo" reactor.)

But "The reality, as ever, is likely to be messier and experts are sounding notes of caution..." All the arguments in favor of SMRs overlook a fundamental issue, said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists: They are too expensive. Despite all the money swilling around the sector, "it's still not enough," he told CNN. Nuclear power cannot compete on cost with alternatives, both fossil fuels and increasingly renewable energy, he said."

Some SMRs also have an issue with fuel. The more unconventional designs, those cooled by salt or gas, often require a special type of fuel called high-assay low-enriched uranium, known as HALEU (pronounced hay-loo). The amounts available are limited and the supply chain has been dominated by Russia, despite efforts to build up a domestic supply. It's a major risk, said Nick Touran [a nuclear engineer and independent consultant]. The biggest challenge nuclear has is competing with natural gas, he said, a "luxury, super expensive fuel may not be the best way." There is still stigma around nuclear waste, too. SMR companies say smaller reactors mean less nuclear waste, but 2022 research from Stanford University suggested some SMRs could actually generate more waste, in part because they are less fuel efficient...

As companies race to prove SMRs can meet the hype, experts appear to be divided in their thinking. For some, SMRs are an expensive — and potentially dangerous — distraction, with timelines that stretch so far into the future they cannot be a genuine answer to soaring needs for clean power right now.

Nuclear engineering/consultant Touran told CNN the small reactors are "a technological solution to a financial problem. No venture capitalists can say, like, 'oh, sure, we'll build a $30 billion plant.' But, if you're down into hundreds of millions, maybe they can do it."

Cheap Green Tech Allows Faster Path To Electrification For the Developing World (japantimes.co.jp) 36

Slashdot reader Mr. Dollar Ton summarizes this article from Bloomberg: According to a new report from think tank "Ember", the availability of cheap green tech can have developing countries profit from earlier investment and skip steps in the transition from fossil to alternatives.

India is put forward as an example. While China's rapid electrification has been hailed as a miracle, by some measures, India is moving ahead faster than China did when it was at similar levels of economic development. It's an indication that clean electricity could be the most direct way to boost growth for other developing economies.

That's mainly because India has access to solar panels and electric cars at a much lower price than China did about a decade ago. Chinese investments lowered the costs of what experts call "modular technologies" — the production of each solar panel, battery cell and electric car enables engineers to learn how to make it more efficiently.

The think tank's team even argues "that countries such as India, which don't have significant domestic fossil-fuel reserves, will become 'electrostates' that meet most of their energy needs through electricity generated from clean sources," according to the article: No country is an electrostate yet, [says Ember strategist Kingsmill Bond], but countries are increasingly turning to green electricity to power their economies. Nations that are less developed than India will see even more advantages as the cost of electricity technologies, from solar panels and electric vehicles to battery components and minerals, continue to fall.

Neither India nor China is going electric purely to cut emissions or meet climate targets, says Bond. They're doing so because it makes economic sense, particularly for India, which imports more than 40% of its primary energy in the form of coal, oil and gas, according to the International Energy Agency. "To grow and have energy independence, India needs to reduce the terrible burden of fossil-fuel imports worth $150 billion each year," said Bond. "India needs to find other solutions...."

[I]f countries like India find ways to grow electrotech manufacturing without absolute dependence on Chinese equipment, electrification could speed up further. With the U.S. and Europe continuing to add exclusions for Chinese-linked electrotech, countries like India will have an incentive to invest in their own manufacturing capacity. "We are probably at a moment of peak Chinese dominance in the electrotech system, as the rest of the world starts to wake up and realize that this is the energy future," he said.

Solar and Wind Overtake Fossil Fuels in the EU (semafor.com) 60

Wind and solar power overtook fossil fuels last year as a source of electricity in the EU for the first time, a new report found. Semafor adds: The milestone was hit largely thanks to a rise in solar power, which generated a record 13% of electricity in the EU, according to Ember. Together, wind and solar hit 30% of EU electricity generation, edging out fossil fuels at 29%.

The shift is especially important with the bloc's alternative to Russian LNG -- Washington -- becoming increasingly unreliable and willing to weaponize economic tools. The US Commerce Secretary threw shade at the bloc's renewable push during Davos, warning that China uses net zero goals to make allies "subservient" by controlling battery and critical mineral supply chains.

Still, renewables now provide nearly half of EU power, with wind and solar outpacing all fossil sources in more than half of member countries. "The stakes of transitioning to clean energy are clearer than ever," the Ember report's author said.

FBI's Washington Post Investigation Shows How Your Printer Can Snitch On You (theintercept.com) 99

alternative_right quotes a report from The Intercept: Federal prosecutors on January 9 charged Aurelio Luis Perez-Lugones, an IT specialist for an unnamed government contractor, with "the offense of unlawful retention of national defense information," according to an FBI affidavit (PDF). The case attracted national attention after federal agents investigating Perez-Lugones searched the home of a Washington Post reporter. But overlooked so far in the media coverage is the fact that a surprising surveillance tool pointed investigators toward Perez-Lugones: an office printer with a photographic memory. News of the investigation broke when the Washington Post reported that investigators seized the work laptop, personal laptop, phone, and smartwatch of journalist Hannah Natanson, who has covered the Trump administration's impact on the federal government and recently wrote about developing more than 1,000 government sources. A Justice Department official told the Post that Perez-Lugones had been messaging Natanson to discuss classified information. The affidavit does not allege that Perez-Lugones disseminated national defense information, only that he unlawfully retained it.

The affidavit provides insight into how Perez-Lugones allegedly attempted to exfiltrate information from a Secure Compartmented Information Facility, or SCIF, and the unexpected way his employer took notice. According to the FBI, Perez-Lugones printed a classified intelligence report, albeit in a roundabout fashion. It's standard for workplace printers to log certain information, such as the names of files they print and the users who printed them. In an apparent attempt to avoid detection, Perez-Lugones, according to the affidavit, took screenshots of classified materials, cropped the screenshots, and pasted them into a Microsoft Word document. By using screenshots instead of text, there would be no record of a classified report printed from the specific workstation. (Depending on the employer's chosen data loss prevention monitoring software, access logs might show a specific user had opened the file and perhaps even tracked whether they took screenshots).

Perez-Lugones allegedly gave the file an innocuous name, "Microsoft Word - Document1," that might not stand out if printer logs were later audited. In this case, however, the affidavit reveals that Perez-Lugones's employer could see not only the typical metadata stored by printers, such as file names, file sizes, and time of printing, but it could also view the actual contents of the printed materials -- in this case, prosecutors say, the screenshots themselves. As the affidavit points out, "Perez-Lugones' employer can retrieve records of print activity on classified systems, including copies of printed documents." [...] Aside from attempting to surreptitiously print a document, Perez-Lugones, investigators say, was also seen allegedly opening a classified document and taking notes, looking "back and forth between the screen corresponding the classified system and the notepad, all the while writing on the notepad." The affidavit doesn't state how this observation was made, but it strongly suggests a video surveillance system was also in play.

Energy Costs Will Decide Which Countries Win the AI Race, Microsoft's Nadella Says (cnbc.com) 60

Energy costs will be key to deciding which country wins the AI race, Microsoft CEO Satya Nadella has said. CNBC: As countries race to build AI infrastructure to capitalize on the technology's promise of huge efficiency gains, Nadella told the World Economic Forum (WEF) on Tuesday that "GDP growth in any place will be directly correlated" to the cost of energy in using AI.

He pointed to a new global commodity in "tokens" -- basic units of processing that are bought by users of AI models, allowing them to run tasks. "The job of every economy and every firm in the economy is to translate these tokens into economic growth, then if you have a cheaper commodity, it's better."

"I would say we will quickly lose even the social permission to actually take something like energy, which is a scarce resource, and use it to generate these tokens, if these tokens are not improving health outcomes, education outcomes, public sector efficiency, private sector competitiveness across all sectors," Nadella said.

A Second US Sphere Could Come To Maryland (theverge.com) 42

Sphere Entertainment plans to build a second U.S. Sphere near Washington, D.C., with a smaller 6,000-seat "mini-Sphere" proposed for National Harbor in Maryland. The venue would retain the signature LED exterior and immersive 4D tech of the Las Vegas Sphere, just at a more compact scale. The Verge reports: The second US sphere would be built in an area known as National Harbor in Prince George's County, Maryland. Located along the Potomac River, National Harbor currently features a convention center, multiple hotels, restaurants, and shops. While Abu Dhabi plans to build a sphere as large as the one in Las Vegas, the National Harbor venue would be one of the first mini-Sphere venues announced last March.

Its capacity would be limited to 6,000 seats instead of over 17,000. But the smaller Sphere would still be hard to miss with an exterior LED exosphere for showcasing the "artistic and branded content" that helped make the original sphere a unique part of the Las Vegas skyline. The inside of the mini-Sphere will feature a high-resolution 16,000 by 16,000 pixel wrap-around screen, the company's immersive sound technology, haptic seating, and "4D environmental effects." For the AI-enhanced version of The Wizard of Oz currently playing in Las Vegas, audiences experience effects like wind, fog, smells, and apples falling from the ceiling.

China Consumed 10.4 Trillion Kilowatt-Hours of Electricity In 2025 - Double the US (reuters.com) 182

Slashdot reader hackingbear summarizes this report from Bloomberg: China consumed totally 10.4 trillion kilowatt hours (10.4 petaWh) in 2025 according to data from the National Energy Administration. That's the highest annual electricity use ever recorded by a single country, and doubled the amount used by the US and surpassed the combined annual total of the EU, Russia, India and Japan.

The surge in demand for power are results of growth in data centers for artificial intelligence (+17% over 2024) and use of electric vehicles (+48.8%)... However, on a per-capita basis, China uses about 7,300 kWh per person vs about 13,000 kWh per American.

More details from Reuters: China's mostly coal-based thermal power generation fell in 2025 for the first time in 10 years, government data showed on Monday, as growing renewable generation met growth in electricity demand even as overall power usage hit a record. The data is a positive signal for the decarbonisation of China's power sector as China sets a course for carbon emissions to peak by 2030... Thermal electricity, generated mostly by coal-fired capacity with a small amount from natural gas, fell 1% in 2025 to 6.29 trillion kilowatt-hours (kWh), according to the National Bureau of Statistics (NBS). It fell more sharply in December, down by 3.2%, from a year earlier, the data showed... [Though the article notes that coal output still edged up to a record high last year.]

Hydropower grew at a steady pace, up 4.1% in December and rising 2.8 % for the full year, the NBS data showed. Nuclear power output rose 3.1 in December and 7.7% in 2025, respectively. Thermal power generation is unlikely to accelerate in 2026 as renewables growth continues apace.

In Europe they sold more electrified Porsches last year than pure combustion-engined models, reports Electrek: in Europe, a majority (57.9%) of Porsche's deliveries were plug-ins, with 1/3 of its European sales being fully electric. For models that have no fully electric version but do have a PHEV (Cayenne and Panamera), the plug-in hybrid version dominated sales.

Of particular note, the Macan sold better with an electric powertrain than it did with a gas one, and was the company's strongest-selling model line and the line with the largest sales growth. The Macan sold 84,328 units globally (up 2% from last year), with 45,367 (53.8%) of those being electric. That 53.8% may seem like a slim majority, but when compared to EV sales globally, it's incredibly high. About a quarter of new cars sold globally were electric in 2025, so Porsche is beating that number with the one model where direct comparisons are available.

And even in the US, about a third of Macans sold were electric. That's notable given the tough year EVs had in the US, with it being the only major car-buying region that experienced a tick down in EV sales... And again, while 1/3 is a minority of Macan sales in the US, it's also well over the US' average ~10% EV sales. So it's clear the EV Macan isn't just performing like an average EV, but well beyond it.

The article adds that "we're quite excited about the Cayenne EV, which will be the most powerful Porsche ever."
