Solar Projects in North Africa + Undersea Cables = Green Energy for Europe? (msn.com) 121

"The abundant sun of northern Africa may soon power Europe's homes and businesses," reports the Washington Post, "as European leaders consider connecting massive North African solar projects to undersea power cables to free their continent from Russian energy." The projects would take advantage of the climate quirk that one side of the Mediterranean is far drearier and cloudier than the other, although Europe and North Africa are geographically close. Abundant desert land also makes North African megaprojects far easier than in Europe, where open spaces tend to be agricultural or mountainous. The sudden need for alternative energy following Russia's invasion of Ukraine means that North African solar projects intended to send electricity to Europe are under active discussion, officials and experts say, as European leaders see a straightforward way to secure large amounts of green power. Past proposals have suggested that North African energy projects could meet as much as 15 percent of Europe's electricity demand.

The interest is especially high in Morocco, where undersea electrical cables already cross the 10-mile span to Spain at the Strait of Gibraltar. Moroccan leaders — who never had any fossil fuels to export — see a chance to promote their country as a renewable energy giant. Europe, meanwhile, wants to hit its ambitious climate goals and address its need for non-Russian energy at the same time. The result is a confluence of interests that could lead to a sudden leap forward for Europe's renewable energy uptake.

More broadly, it is a test for the concept of shipping green energy from sunny parts of the world to regions where the sun doesn't shine as brightly.... Europe alone doesn't have "the potential for the scale to create the dimensions of the renewable energy that we need," said European Commission Vice President Frans Timmermans, speaking alongside Moroccan Foreign Minister Nasser Bourita.

The article cites estimates from the International Renewable Energy Agency that North Africa's "installable capacity" is 2,792 gigawatts of solar power and 223 gigawatts of wind power. Laura El-Katiri, a fellow at the European Council on Foreign Relations who specializes in North African renewable energy, writes that could generate more than two and a half times Europe's 2021 electricity output.

Germany Quits Nuclear Power, Closes Its Final Three Plants (cnn.com) 241

"Germany's final three nuclear power plants close their doors on Saturday," reports CNN, "marking the end of the country's nuclear era that has spanned more than six decades...." [D]espite last-minute calls to keep the plants online amid an energy crisis, the German government has been steadfast. "The position of the German government is clear: nuclear power is not green. Nor is it sustainable," Steffi Lemke, Germany's Federal Minister for the Environment and Consumer Protection and a Green Party member, told CNN."We are embarking on a new era of energy production," she said.

The closure of the three plants — Emsland, Isar 2 and Neckarwestheim — represents the culmination of a plan set in motion more than 20 years ago. But its roots are even older. In the 1970s, a strong anti-nuclear movement in Germany emerged. Disparate groups came together to protest new power plants, concerned about the risks posed by the technology and, for some, the link to nuclear weapons. The movement gave birth to the Green Party, which is now part of the governing coalition...

For critics of Germany's policy, however, it's irrational to turn off a low-carbon source of energy as the impacts of the climate crisis intensify. "We need to keep existing, safe nuclear reactors operating while simultaneously ramping up renewables as fast as possible," Leah Stokes, a professor of climate and energy policy at the University of California, Santa Barbara, told CNN. The big risk, she said, is that fossil fuels fill the energy gap left by nuclear. Reductions in Germany's nuclear energy since Fukushima have been primarily offset by increases in coal, according to research published last year.

Germany plans to replace the roughly 6% of electricity generated by the three nuclear plants with renewables, but also gas and coal.... Now Germany must work out what do with the deadly, high-level radioactive waste, which can remain dangerous for hundreds of thousands of years.

CNN also notes how other countries approach nuclear power:

Why Is 'Juice Jacking' Suddenly Back In the News? (krebsonsecurity.com) 32

An anonymous reader shares a report from KrebsOnSecurity: KrebsOnSecurity received a nice bump in traffic this week thanks to tweets from the Federal Bureau of Investigation (FBI) and the Federal Communications Commission (FCC) about "juice jacking," a term first coined here in 2011 to describe a potential threat of data theft when one plugs their mobile device into a public charging kiosk. It remains unclear what may have prompted the alerts, but the good news is that there are some fairly basic things you can do to avoid having to worry about juice jacking.

The term juice jacking crept into the collective paranoia of gadget geeks in the summer of 2011, thanks to the headline for a story here about researchers at the DEFCON hacker convention in Vegas who'd set up a mobile charging station designed to educate the unwary to the reality that many mobile devices were set up to connect to a computer and immediately sync data by default. Since then, Apple, Google and other mobile device makers have changed the way their hardware and software works so that their devices no longer automatically sync data when one plugs them into a computer with a USB charging cable. Instead, users are presented with a prompt asking if they wish to trust a connected computer before any data transfer can take place. On the other hand, the technology needed to conduct a sneaky juice jacking attack has become far more miniaturized, accessible and cheap. And there are now several products anyone can buy that are custom-built to enable juice jacking attacks. [...]

How seriously should we take the recent FBI warning? An investigation by the myth-busting site Snopes suggests the FBI tweet was just a public service announcement based on a dated advisory. Snopes reached out to both the FBI and the FCC to request data about how widespread the threat of juice jacking is in 2023. "The FBI replied that its tweet was a 'standard PSA-type post' that stemmed from the FCC warning," Snopes reported. "An FCC spokesperson told Snopes that the commission wanted to make sure that their advisory on "juice-jacking," first issued in 2019 and later updated in 2021, was up-to-date so as to ensure 'the consumers have the most up-to-date information.' The official, who requested anonymity, added that they had not seen any rise in instances of consumer complaints about juice-jacking."
The best way to protect yourself from juice jacking is by using your own gear to charge and transfer data from your device(s) to another.

"Juice jacking isn't possible if a device is charged via a trusted AC adapter, battery backup device, or through a USB cable with only power wires and no data wires present," says security researcher Brian Krebs. "If you lack these things in a bind and still need to use a public charging kiosk or random computer, at least power your device off before plugging it in."

China the Largest Buyer of Chipmaking Machines As Sales Hit An All-Time High (theregister.com) 18

Global sales of semiconductor fab equipment grew by 5 percent during 2022 to hit an all-time high, with China the largest buyer despite a fall in its investment amid the standoff with the US over access to chips and other technology. The Register reports: The figures come from SEMI, the industry body for electronics manufacturing and supply chain, in a new Worldwide Semiconductor Equipment Market Statistics (WWSEMS) report. According to the report, sales of chipmaking kit hit $107.6 billion last year, up from $102.6 billion in 2021, as semiconductor companies invested to add more capacity, despite the downturn that took hold in the latter half of last year as inflation gripped many economies.

"The record high for semiconductor manufacturing equipment sales in 2022 stems from the industry's drive to add the fab capacity required to support long-term growth and innovations in key end markets including high-performance computing and automotive," claimed SEMI president and CEO Ajit Manocha. These results also reflect a desire by chipmakers in multiple regions to avoid any repetition of the supply chain issues that surfaced during the pandemic, he added. Many companies cut investment then, in response to falling orders, leading to shortages when demand picked up again.

China remained the largest market for semiconductor equipment despite seeing a 5 percent slowdown in investments compared with the previous year, according to SEMI. This drop is likely caused by US moves to curtail China's ability to make advanced chips, which has now extended beyond American companies such as Applied Materials to include others such as Dutch photolithography giant ASML, as Washington has browbeaten allied nations including the Netherlands and Japan to join its sanctions.

Nvidia's Top AI Chips Are Selling for More Than $40,000 on eBay (cnbc.com) 32

Nvidia's most-advanced graphics cards are selling for more than $40,000 on eBay, as demand soars for chips needed to train and deploy artificial intelligence software. From a report: The prices for Nvidia's H100 processors were noted by 3D gaming pioneer and former Meta consulting technology chief John Carmack on Twitter. On Friday, at least eight H100s were listed on eBay at prices ranging from $39,995 to just under $46,000. Some retailers have offered it in the past for around $36,000. The H100, announced last year, is Nvidia's latest flagship AI chip, succeeding the A100, a roughly $10,000 chip that's been called the "workhorse" for AI applications. Developers are using the H100 to build so-called large language models (LLMs), which are at the heart of AI applications like OpenAI's ChatGPT. Running those systems is expensive and requires powerful computers to churn through terabytes of data for days or weeks at a time. They also rely on hefty computing power so the AI model can generate text, images or predictions. Training AI models, especially large ones like GPT, requires hundreds of high-end Nvidia GPUs working together.

Hackers Claim Vast Access To Western Digital Systems (techcrunch.com) 29

An anonymous reader quotes a report from TechCrunch: The hackers who breached data storage giant Western Digital claim to have stolen around 10 terabytes of data from the company, including reams of customer information. The extortionists are pushing the company to negotiate a ransom -- of "minimum 8 figures" -- in exchange for not publishing the stolen data. On April 3, Western Digital disclosed "a network security incident" saying hackers had exfiltrated data after hacking into "a number of the Company's systems." At the time, Western Digital provided few details about exactly what data the hackers stole, saying in a statement that the hackers "obtained certain data from its systems and [Western Digital] is working to understand the nature and scope of that data."

One of the hackers spoke with TechCrunch and provided more details, with the goal of verifying their claims. The hacker shared a file that was digitally signed with Western Digital's code-signing certificate, showing they could now digitally sign files to impersonate Western Digital. Two security researchers also looked at the file and agreed it is signed with the company's certificate. The hackers also shared phone numbers allegedly belonging to several company executives. TechCrunch called the numbers. Most of the calls rang but went to automated voicemail messages. Two of the phone numbers had voicemail greetings that mentioned the names of the executives that the hackers claimed were associated with the numbers. The two phone numbers are not public.

Screenshots shared by the hacker show a folder from a Box account apparently belonging to Western Digital, an internal email, files stored in a PrivateArk instance (a cybersecurity product), and a screenshot of a group call where one of the participants is identified as Western Digital's chief information security officer. They also said they were able to steal data from the company's SAP Backoffice, a backend interface that helps companies manage e-commerce data. The hacker said that their goal when they hacked Western Digital was to make money, though they decided against using ransomware to encrypt the company's files. [...] If Western Digital doesn't get back to them, the hacker said, they are ready to start publishing the stolen data on the website of the ransomware gang Alphv. The hacker said they are not directly affiliated with Alphv but "I know them to be professional."
Western Digital said they're declining to comment or answer questions about the hacker's claims.

DDoS Attacks Shifting To VPS Infrastructure For Increased Power (bleepingcomputer.com) 5

Hyper-volumetric DDoS (distributed denial of service) attacks in the first quarter of 2023 have shifted from relying on compromised IoT devices to leveraging breached Virtual Private Servers (VPS). BleepingComputer reports: According to internet security company Cloudflare, the newer generation of botnets gradually abandoned the tactic of building large swarms of individually weak IoT devices and are now shifting towards enslaving vulnerable and misconfigured VPS servers using leaked API credentials or known exploits. This approach helps the threat actors build high-performance botnets easier and often quicker, which can be up to 5,000 times stronger than IoT-based botnets.

"The new generation of botnets uses a fraction of the amount of devices, but each device is substantially stronger," explains Cloudflare in the report. "Cloud computing providers offer virtual private servers to allow start ups and businesses to create performant applications. The downside is that it also allows attackers to create high-performance botnets that can be as much as 5,000x stronger." Cloudflare has been working with key cloud computing providers and partners to crack down on these emerging VPS-based threats and says it has succeeded in taking down substantial portions of these novel botnets.

Nvidia Announces the RTX 4070, a 'Somewhat Reasonably Priced Desktop GPU' (polygon.com) 89

Nvidia announced the GeForce RTX 4070 desktop GPU, a move that anyone who's been putting off a new midrange DIY PC build has likely been eagerly awaiting. It puts the company's impressive Ada Lovelace graphics architecture within grasp for people who don't want to spend $1,000 or more on a huge graphics card. From a report: It'll launch Thursday, April 13, starting at $599 for Nvidia's Founders Edition single-fan model. As is always the case, other manufacturers like Asus, Zotac, Gigabyte, MSI, and others are putting out factory overclocked variants, too. The Verge already has a full review up for the RTX 4070.

The RTX 4070 Founders Edition card requires a 650 W power supply, and it connects via two PCIe 8-pin cables (an adapter comes in the box). Alternatively, it can connect via a PCIe Gen 5 cable that supports 300 W or higher. The RTX 4070 won't require a humongous case, as it's a two-slot card that's quite a bit smaller than the RTX 4080. It's 9.6 inches long and 4.4 inches wide, which is just about the same size as my RTX 3070 Ti Founders Edition card. Despite being a lower-end GPU compared to Nvidia's RTX 4080 or RTX 4090, it retains the DLSS 3 marquee selling point. It's the next iteration of Nvidia's upscaling technique that drops the render resolution to make games run better, then uses the GPU's AI cores to intelligently upscale what you see.

Intel To Work With Arm on Chip Manufacturing Compatibility (reuters.com) 22

Intel on Wednesday said its chip contract manufacturing division will work with U.K.-based chip designer Arm to ensure that mobile phone chips and other products that use Arm's technology can be made in Intel's factories. From a report: Once the biggest name in chips known as central processing units (CPUs), Intel has seen long seen its technological manufacturing edge blunted by rivals such as Taiwan Semiconductor Manufacturing Co, the world leader in making chips for customers such as Apple. Intel's turnaround strategy hinges in part on opening up its factories to other chip companies, particularly those in mobile phones. It has said firms such as Qualcomm are planning to use its factories for future chip designs. "There is growing demand for computing power driven by the digitization of everything, but until now ... customers have had limited options for designing around the most advanced mobile technology," Pat Gelsinger, Intel's chief executive, said in a statement.

Sony Backs Maker of Tiny Raspberry Pi Computers With Fresh Funding, Access To AI Chips (cnbc.com) 31

The company behind the Raspberry Pi line of computers has raised fresh investment from Sony's semiconductor unit, in a deal aimed at advancing its efforts in artificial intelligence. From a report: Sony Semiconductor Solutions, a subsidiary of Sony Corporation, invested an undisclosed amount in Raspberry Pi Ltd, the trading company of Raspberry Pi, the company said in a statement on Wednesday. The extent of the funding was not revealed, but Eben Upton, Raspberry Pi's co-founder and CEO, said that the firm raised the cash at the same $500 million valuation it was worth in a 2021 funding round, when it brought in $45 million.

Upton established Raspberry Pi in 2012 with the aim of making computing more accessible to young people. Raspberry Pi's tiny single-board computers are the size of a credit card and have been used to build everything from high-altitude balloons to small radio-controlled submarines. Raspberry Pi's customers were mainly hobbyists and teachers in the early days. The company has since become a more active player in the enterprise -- in a typical year, roughly 70% of its sales now come from commercial customers embedding its products into factories or consumer devices, Upton told CNBC.

The NYPD Is Bringing Back Its Robot Dog (theverge.com) 54

An anonymous reader quotes a report from The Verge: The New York Police Department is reenlisting Digidog, the four-legged robot that the city faced backlash for deploying a few years back, as reported earlier by The New York Times. NYC Mayor Eric Adams announced the news during a press event on Tuesday, stating that the use of Digidog in the city can "save lives." Digidog -- also known as Spot -- is a remote-controlled robot made by the Hyundai-owned Boston Dynamics. It's designed to work in situations that may pose a threat to humans, helping to do things like perform inspections in dangerous areas and monitor construction sites. However, Boston Dynamics also touts its use as a public safety tool, which the NYPD has tried in the past.

City officials say that the NYPD will acquire two robot dogs for a total of $750,000, according to the NYT, and that they will only be used during life-threatening situations, such as bomb threats. "I believe that technology is here; we cannot be afraid of it," Mayor Adams said during Tuesday's press conference. "A few loud people were opposed to it, and we took a step back — that is not how I operate. I operate on looking at what's best for the city."
The Surveillance Technology Oversight Project (STOP), a group that advocates against the use of local and state-level surveillance, has denounced Mayor Adams' move. "The NYPD is turning bad science fiction into terrible policing," Albert Fox Cahn, STOP's executive director, says in a statement. "New York deserves real safety, not a knockoff robocop. Wasting public dollars to invade New Yorkers' privacy is a dangerous police stunt."

Shutting Down Nuclear Power Could Increase Air Pollution, Finds MIT Study 155

If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate. The findings appear in the journal Nature Energy. MIT News reports: They lay out a scenario in which every nuclear power plant in the country has shut down, and consider how other sources such as coal, natural gas, and renewable energy would fill the resulting energy needs throughout an entire year. Their analysis reveals that indeed, air pollution would increase, as coal, gas, and oil sources ramp up to compensate for nuclear power's absence. This in itself may not be surprising, but the team has put numbers to the prediction, estimating that the increase in air pollution would have serious health effects, resulting in an additional 5,200 pollution-related deaths over a single year.

If, however, more renewable energy sources become available to supply the energy grid, as they are expected to by the year 2030, air pollution would be curtailed, though not entirely. The team found that even under this heartier renewable scenario, there is still a slight increase in air pollution in some parts of the country, resulting in a total of 260 pollution-related deaths over one year. When they looked at the populations directly affected by the increased pollution, they found that Black or African American communities -- a disproportionate number of whom live near fossil-fuel plants -- experienced the greatest exposure.
"They also calculated that more people are also likely to die prematurely due to climate impacts from the increase in carbon dioxide emissions, as the grid compensates for nuclear power's absence," adds the report. "The climate-related effects from this additional influx of carbon dioxide could lead to 160,000 additional deaths over the next century."

Lead author Lyssa Freese, a graduate student in MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS), said: "We need to be thoughtful about how we're retiring nuclear power plants if we are trying to think about them as part of an energy system. Shutting down something that doesn't have direct emissions itself can still lead to increases in emissions, because the grid system will respond."

The Biggest EV Battery Recycling Plant In the US Is Open For Business (canarymedia.com) 62

Ascend Elements opened a recycling plant in Covington, Georgia in late March that it says is the largest electric-vehicle battery recycling facility in North America. "It can process 30,000 metric tons of input each year, breaking down old batteries and prepping the most valuable materials inside to be processed and turned into new batteries," reports Canary Media. "That capacity equates to breaking down the battery packs from 70,000 electric vehicles annually, said Ascend CEO Mike O'Kronley." From the report: Recycling can deliver new battery materials without the expense and environmental impact of new mining. It is extremely hard to develop new mines in the U.S., but the federal government is lavishing funds on new battery recycling plants. The revamped EV tax credits also call for increasing shares of domestically sourced batteries and battery materials. Those market and policy shifts made recycling sufficiently desirable that Ascend is paying other companies for their old batteries. At the moment, those deals are mostly with EV or battery makers that have high volumes to get rid of.

"Paying for these spent batteries keeps them from going into the landfill," O'Kronley told Canary Media. "It's better to get paid for it rather than throw them away." Ascend also accepts used consumer electronics from battery-collection programs, such as Call2Recycle. That's not to say there are enough old batteries coming in to fill the factory. Currently, 80 to 90 percent of what's going into Ascend's Covington facility is scrap materials from battery factories, including SK Battery America's plant in Commerce, Georgia.

That relationship influenced Ascend's choice of location: Covington sits in the emerging "Battery Belt," a swath of new battery factories and electric-vehicle plants opening up across the Midwest and the Carolinas, Georgia, Tennessee and Kentucky (look for all the blue icons in this White House map of new industrial investments). Fellow battery-recycling startup Redwood Materials also chose South Carolina for a forthcoming $3.5 billion recycling facility. "There will need to be a recycling plant within about an hour's drive of every single one of those [new battery gigafactories]," O'Kronley said. "You don't want to be [long-distance] shipping these very large, heavy EV batteries that are classified as Class 9 hazardous materials."
The report notes that the company's second commercial-scale facility in Hopkinsville, Kentucky will "introduce a brand-new technique for efficiently extracting cathode materials from black mass, which Ascend has dubbed 'hydro to cathode.'"

Tesla To Open Megapack Battery Factory In Shanghai (washingtonpost.com) 16

Tesla will open a factory in Shanghai to produce its Megapack large-scale batteries, cementing another foothold for the U.S. company in China even as political and economic tensions between Washington and Beijing swirl. The Washington Post reports: Tesla said in a brief tweet on Sunday that its "Megafactory" in Shanghai will be capable of producing 10,000 Megapacks annually, an output equivalent to its other Megafactory in Lathrop, Calif., about 70 miles east of San Francisco. The company, which disbanded its public relations department, did not provide further details. Elon Musk, Tesla's chief executive, said in a tweet that the factory in Shanghai would "supplement" the production in California.

The Chinese factory will be built in Lingang, a suburban area of Shanghai where Tesla's vehicle factory is also located, according to Chinese media. Lu Yu, an official in Lingang, told local media that production could start as soon as the second quarter of 2024. The investment in China by Tesla comes after the coronavirus pandemic brought some supply chains to a halt as factories in China shut down amid strict "zero covid" protocols. With those setbacks still fresh in many executives' minds -- and amid concerns over alleged human rights violations and chilly relations between Washington and Beijing -- China has struggled to attract foreign investment since the pandemic.

The Megapacks differ from most of Tesla's consumer-focused offerings, like the electric vehicles it is widely known for, in that they are more a piece of energy infrastructure than a consumer product. The batteries are intended to store energy from renewable sources such as wind and solar, allowing energy to be drawn even when the sun isn't shining and the wind isn't blowing. Batteries like the Megapack are not yet widely implemented in the United States and purchases of the technology have mostly been kept under wraps. But the Megapack has been bought for Apple's renewable energy storage project in California, according to the Verge, and for a storage project outside Houston, Bloomberg first reported. A Megapack, Tesla says, "stores energy for the grid reliably and safely, eliminating the need for gas peaker plants and helping to avoid outages." Each pack can store enough energy to power 3,600 homes for an hour, Tesla says.

'Rest of World' Photo Contest Highlight's Tech and Solar's Impact (restofworld.org) 14

Since launching in 2020, the nonprofit site RestofWorld.org has been covering global tech news from 100 countries, the site announced this week. "But at Rest of World, the story of tech is as big as the world that's using it" — so they just finished their first international photography contest. We asked our readers to send us images of technology's impact in their communities — as seen from their lenses. We received 548 entries from around the world, including from Afghanistan, Mexico, Nigeria, Iraq, and Pakistan. Photographers captured a wide range of issues, from facial recognition software used at gated communities in Brazil to students studying on their phones during a power outage in India.
They recognized 10 photos in all — three winners, and seven "honorable mentions" — including one showing a surgeon implanting a venomous snake with a radio telemetry device in India "to try and mitigate human-snake conflict in the region," as well as a stunning aerial view of a vast solar park in Dubai. There's a solar-powered cooking device in India, and the face of an old man in Nepal using headphones for the first time in his life.

And the #1 photo shows children in rural Palestine watching TV "with electricity generated from solar panels at their home inside a cave," vividly illustrating the point that they'd turned to a decentralized, self-generated power technology. ("For decades, rural Palestinian communities in Masafer Yatta have lobbied for connection to the electric grid, but the Israeli state does not recognize such villages as legitimate and refuses to issue any kind of master plan for their development.")

Fully Recyclable Printed Electronics Produced Using Water Instead of Toxic Chemicals (duke.edu) 38

Duke University announces their engineers "have produced the world's first fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process" — bypassing the need for hazardous chemicals.

Electrical/computer engineering professor Aaron Franklin led the study, according to Duke's announcement: In previous work, Franklin and his group demonstrated the first fully recyclable printed electronics. The devices used three carbon-based inks: semiconducting carbon nanotubes, conductive graphene and insulating nanocellulose. In trying to adapt the original process to only use water, the carbon nanotubes presented the largest challenge.... In the paper, Franklin and his group develop a cyclical process in which the device is rinsed with water, dried in relatively low heat and printed on again. When the amount of surfactant used in the ink is also tuned down, the researchers show that their inks and processes can create fully functional, fully recyclable, fully water-based transistors....

Franklin explains that, by demonstrating a transistor first, he hopes to signal to the rest of the field that there is a viable path toward making some electronics manufacturing processes much more environmentally friendly. Franklin has already proven that nearly 100% of the carbon nanotubes and graphene used in printing can be recovered and reused in the same process, losing very little of the substances or their performance viability. Because nanocellulose is made from wood, it can simply be recycled or biodegraded like paper. And while the process does use a lot of water, it's not nearly as much as what is required to deal with the toxic chemicals used in traditional fabrication methods.

According to a United Nations estimate, less than a quarter of the millions of pounds of electronics thrown away each year is recycled. And the problem is only going to get worse as the world eventually upgrades to 6G devices and the Internet of Things (IoT) continues to expand. So any dent that could be made in this growing mountain of electronic trash is important to pursue. While more work needs to be done, Franklin says the approach could be used in the manufacturing of other electronic components like the screens and displays that are now ubiquitous to society. Every electronic display has a backplane of thin-film transistors similar to what is demonstrated in the paper. The current fabrication technology is high-energy and relies on hazardous chemicals as well as toxic gasses. The entire industry has been flagged for immediate attention by the US Environmental Protection Agency.

"The performance of our thin-film transistors doesn't match the best currently being manufactured, but they're competitive enough to show the research community that we should all be doing more work to make these processes more environmentally friendly," Franklin said.

Libreboot Founder's 'Minifree' Sells Free-Software Laptops with Libreboot Preinstalled (minifree.org) 20

Slashdot reader unixbhaskar writes: A company in the U.K. calling itself Minifree has started to ship old Thinkpad (specifically the X series and T series models) with Libreboot firmware. Which is based on coreboot firmware.
More specifically, Libreboot is the free-as-in-speech replacement for proprietary BIOS/UEFI firmware, the site notes, "offering faster boots speeds, better security and many advanced features compared to most proprietary boot firmware." Those advanced features include the GNU project's multiple-OS-booting "grand unified bootloader" GNU GRUB directly in the boot flash, along with several other customization options. "The aim is simple: make it easy to have a computer that was made to run entirely on Free Software at every level, meaning no proprietary software of any kind. That includes the boot firmware, operating system, drivers and applications."

The Libreboot project's founder is also the founder of Minifree, and the profits from Minifree's sales directly fund the Libreboot project. (The whole Minifree web site runs on Libreboot-powered servers, on a network behind a Libreboot-powered router...) Their site points out that Minifree Ltd has also privately funded several new board ports to coreboot, including 90,000 USD to Raptor Engineering for ASUS KGPE-D16 and KCMA-D8 libreboot support, and 4000 AUD to Damien Zammit for Gigabyte GA-G41M-ES2L and Intel D510MO libreboot support.

The installed OS on the laptops is either encrypted Debian (KDE Plasma desktop environment), with full driver support, or "other Linux distro/BSD (e.g. OpenBSD, FreeBSD) at your request... Advanced features like encrypted /boot (GNU+Linux only), signed kernels and more are available." And the laptops are also shipped — worldwide — with "your choice of 480/960GB SSD or 2x480GB/2x960GB RAID1 SSDs, with good batteries and 16GB RAM. Free technical support via email/IRC plus 5-year warranty."

But judging by their FAQ, the support is even more extensive. "If you brick your Minifree laptop when updating Libreboot, Minifree will unbrick it for free if you send it back to us. Even if your warranty has expired! However, such bricking is rare."

How Old Coal Mines Are Now Producing Clean Geothermal Energy (bbc.com) 66

Kenneth Stephen (Slashdot reader #1,950) writes: As the world rolls back on using coal to extract energy, it leaves behind empty coal mines. The BBC reports that the UK is actively using these coal mines as a source of geothermal energy.
The BBC visits a wine warehouse in the northeast England town Gateshead, where old coal mines "could still have a role to play in heating homes — but this time, without burning fossil fuels." A new district heating system in Gateshead is poised to begin warming homes and buildings in the area at a cost 5% below market rate, using the clean heat from its mines 150m (490ft) below the ground.
The water in the mines is naturally heated in the surrounding rocks to 20 degrees C (68 degrees Fahrenheit), according to the video report — so a heat exchanger on the surface just repurposes the extracted heat for energy consumers. It's a technique that's also being adopted in the Netherlands. But it's especially applicable in the U.K., where a quarter of homes are above old coal fields (as are 9 of its 10 major urban centers).

The report points out that coal is the world's largest source of CO2 emissions, but now coal production in the UK has fallen by 94% in the last 10 years. "So what happens when the coal mines that used to power our cities are no longer used?"

Walmart US CEO Says Automation At Stores Won't Displace Workers (businessinsider.com) 57

An anonymous reader quotes a report from Insider: Walmart will be increasingly relying on automation at its stores in the coming years -- but that won't diminish the country's largest private employer's workforce, company leaders said during an investor event this week. The Bentonville, Arkansas-based retail giant recently made headlines when it announced that 65% of its stores will be "serviced by automation" by the end of fiscal year 2026. Walmart currently has more than 4,700 stores throughout the US and employs roughly 1.6 million people nationwide.

More specifically, one area where Walmart is seeking to increase investment is in market fulfillment centers (MFCs), which are automated fulfillment centers built within, or added to, a store. Walmart piloted this concept at a store in Salem, New Jersey, in 2019, using automated robot technology from Alert Innovation -- a robotics company Walmart acquired in October 2022. Since then, Walmart has built MFCs at several stores, such as in Jacksonville, Florida, and Dallas, Texas. Those include "manual MFCs," where associates pick items for online orders but in a separate area from the sales floor.

Walmart will still need at least the same level of workers to help in stores even as automation picks up, company leaders say. John Furner, Walmart US president and CEO, told investors this week that automation "helps" employees, as it will result in less manual labor. "Over time, we believe we'll have the same or more associates and a larger business overall," Furner said. "There will be new roles emerging that are less manual, better designed to serve customers, and pay more."

Walmart Plans Own EV Charger Network At US Stores By 2030 (reuters.com) 55

Walmart plans to have its own network of electric vehicle charging stations by 2030 to tap into the growing adoption of EVs in the United States. Reuters reports: The new fast-charging stations will be placed at thousands of Walmart and Sam's Club stores, alongside nearly 1,300 it already offers as part of a deal with Volkswagen unit Electrify America, one of the country's largest open public EV networks. Walmart's more than 5,000 stores and Sam's Club warehouses are located within 10 miles of about 90% of Americans.

"We have the ability to address range and charging anxiety in a way that no one else can in this country," Vishal Kapadia, Walmart's recently appointed senior vice president of Energy Transformation, said in an interview. Owning its chargers, instead of partnering with a network operator, will help Walmart address reliability and cost issues, Kapadia said. Kapadia said he expects the new charge points to be direct-current fast chargers, with about four chargers on average installed per store.
