"Linux fans rejoice!" writes Hot Hardware. " Pine64's newest smartphone is officially available for pre-order." PinePhone Pro Explorer Edition pre-orders opened up Tuesday. Devices that are pre-ordered before January 18th will be shipped from Pine64's Hong Kong warehouse by January 24th and should arrive by early February.... According to Pine64, the PinePhone Pro Explorer Edition is the "fastest mainline Linux smartphone on the market." It uses a Rockchip RK3399S SoC that is composed of two ARM A72 cores (1.5GHz) and four A53 efficiency cores (1.5GHz)....

Consumers will also likely be pleased with the price of the device. The PinePhone Pro Explorer Edition currently rings in at $399 USD. The production run is purportedly "large" and interested consumers should therefore be able to easily purchase the device at this price.
Liliputing adds: While the PinePhone Pro has better hardware than the original PinePhone, Pine64 plans to continue selling both phones indefinitely. The first-gen phone will continue to sell for $150 to $200, offering an entry-level option for folks that want to experiment with mobile Linux, while the higher-priced PinePhone Pro should offer a hardware experience closer to what folks would expect from a modern mid-range phone....

In addition to the PinePhone Keyboard, the recently launched PinePhone wireless charging case, fingerprint reader case, and LoRa cases should all work with either phone.

But the new phone has a faster processor, more memory and storage, higher-resolution cameras, a higher-speed USB-C port and support for WiFi 5 and Bluetooth 4.1. And those features should make it a little more viable as a replacement for an iPhone or Android device... if you're comfortable running work-in-progress software.
They also add that "Thanks to the recent launch of the $50 PinePhone Keyboard, you can also think of the PinePhone Pro as a $400 phone that can be used as a $449 mini-laptop...."

And the Pine64 site's January update also points out that "Pico 8 Raspberry Pi port works on the PinePhone," adding "yes, it does run DOOM."

"As part of their growing battle against popular open source software tool youtube-dl, three major music labels are now suing Uberspace, the company that currently hosts the official youtube-dl homepage," reports TorrentFreak: According to plaintiffs Sony, Universal and Warner, youtube-dl circumvents YouTube's "rolling cipher" technology, something a German court found to be illegal in 2017.... While the RIAA's effort to take down youtube-dl from GitHub grabbed all the headlines, moves had already been underway weeks before that in Germany. Law firm Rasch works with several major music industry players and it was on their behalf that cease-and-desist orders were sent to local hosting service Uberspace. The RIAA complained that the company was hosting the official youtube-dl website although the tool itself was hosted elsewhere.

"The software itself wasn't hosted on our systems anyway so, to be honest, I felt it to be quite ridiculous to involve us in this issue anyway — a lawyer specializing in IT laws should know better," Jonas Pasche from Uberspace said at the time.

In emailed correspondence today Uberspace informed TorrentFreak that, following the cease-and-desist in October 2020, three major music labels are now suing the company in Germany... According to the labels, youtube-dl poses a risk to their business and enables users to download their artists' copyrighted works by circumventing YouTube's technical measures. As a result, Uberspace should not be playing a part in the tool's operations by hosting its website if it does not wish to find itself liable too....

The alleged illegality of youtube-dl is indeed controversial. While YouTube's terms of service generally disallow downloading, in Germany there is the right to make a private copy, with local rights group GEMA collecting fees to compensate for just that. Equally, when users upload content to YouTube under a Creative Commons license, for example, they agree to others in the community making use of that content. "Even if YouTube doesn't provide video download functionality right out of the box, the videos are not provided with copy protection," says former EU MP Julia Reda from the Society for Freedom Rights (GFF) to NetzPolitik. "Not only does YouTube pay license fees for music, we all pay fees for the right to private copying in the form of the device fee, which is levied with every purchase of smartphones or storage media," says Reda.

"Despite this double payment, Sony, Universal and Warner Music want to prevent us from exercising our right to private copying by saving YouTube videos locally on the hard drive."

The conglomerate led by Mukesh Ambani, Asia's richest man, announced plans to invest $76 billion toward clean energy projects, dwarfing an earlier commitment of $10 billion by the world's biggest fossil-fuel billionaire. From a report: Reliance Industries, controlled by Ambani, has signed pacts with the state government of Gujarat for a total investment of 5.96 trillion rupees ($81 billion), according to an exchange filing Thursday. Of this, about 5 trillion rupees would be used over the next 15 years to build 100 gigawatts of renewable power projects and a green hydrogen network while 600 billion rupees will be for factories making solar modules, hydrogen electrolyzers, fuel cells and storage batteries, the filing said. The remaining sum is to be spent in the retail-to-refining group's new and existing projects, including the upgrade of its telecom network for 5G services and expansion of its consumer retail businesses. Reliance has already "started the process of scouting land" for its renewable energy power projects and has requested the Gujarat administration for 450,000 acres (182,110 hectares) in the arid Kutch region. Though the investment pact is just a memorandum of understanding right now, it outlines the scope of Ambani's green ambitions and is a big step up from the $10 billion investment over three years he had announced in June. Ambani is in the midst of transforming his fossil fuel-fed empire and pivoting it toward green energy and digital technology.

Scientists from Lancaster University say that we might be close to combining SSDs and RAM into one component. "UltraRAM," as it's being called, is described as a memory technology which "combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency, and endurance of a working memory, like DRAM." The researchers detailed the breakthrough in a recently published paper. Tom's Hardware reports: The fundamental science behind UltraRAM is that it uses the unique properties of compound semiconductors, commonly used in photonic devices such as LEDs, lasers, and infrared detectors can now be mass-produced on silicon. The researchers claim that the latest incarnation on silicon outperforms the technology as tested on Gallium Arsenide semiconductor wafers. Some extrapolated numbers for UltraRAM are that it will offer "data storage times of at least 1,000 years," and its fast switching speed and program-erase cycling endurance is "one hundred to one thousand times better than flash." Add these qualities to the DRAM-like speed, energy efficiency, and endurance, and this novel memory type sounds hard for tech companies to ignore.

If you read between the lines above, you can see that UltraRAM is envisioned to break the divide between RAM and storage. So, in theory, you could use it as a one-shot solution to fill these currently separate requirements. In a PC system, that would mean you would get a chunk of UltraRAM, say 2TB, and that would cover both your RAM and storage needs. The shift, if it lives up to its potential, would be a great way to push forward with the popular trend towards in-memory processing. After all, your storage would be your memory -- with UltraRAM; it is the same silicon.

There's a problem with the lithium (Li) ion batteries used in electric cars and for energy storage. The BBC reports that the most widely-used methods for battery recycling won't work nearly as well, since Li batteries are "larger, heavier, much more complex and even dangerous if taken apart wrong."

Slashdot reader quonset shared their report: In your average battery recycling plant, battery parts are shredded down into a powder, and then that powder is either melted (pyrometallurgy) or dissolved in acid (hydrometallurgy). But Li batteries are made up of lots of different parts that could explode if they're not disassembled carefully. And even when Li batteries are broken down this way, the products aren't easy to reuse. "The current method of simply shredding everything and trying to purify a complex mixture results in expensive processes with low value products," says Andrew Abbott, a physical chemist at the University of Leicester. As a result, it costs more to recycle them than to mine more lithium to make new ones. Also, since large scale, cheap ways to recycle Li batteries are lagging behind, only about 5% of Li batteries are recycled globally, meaning the majority are simply going to waste....
Fortunately, the article points out that several labs are working on developing more efficient and eco-friendly ways to recycle Li batteries [D]isassembling Li batteries is currently being done predominantly by hand in lab settings, which will need to change if direct recycling is to compete with more traditional recycling methods. "In the future, there will need to be more technology in disassembly," says Abbott. "If a battery is assembled using robots, it is logical that it needs to be disassembled in the same way." Abbott's team at the Faraday Institution in the UK is investigating the robotic disassembly of Li batteries as part of the ReLib Project, which specialises in the recycling and reuse of Li batteries.

The team has also found a way to achieve direct recycling of the anode and cathode using an ultrasonic probe, "like what the dentist uses to clean your teeth," he explains. "It focuses ultrasound on a surface which creates tiny bubbles that implode and blast the coating off the surface." This process avoids having to shred the battery parts, which can make recovering them exceedingly difficult. According to Abbott's team's research, this ultrasonic recycling method can process 100 times more material over the same period than the more traditional hydrometallurgy method. He says it can also be done for less than half the cost of creating a new battery from virgin material...
Another idea: replacing lithium-ion batteries altogether with something more eco-friendly: Jodie Lutkenhaus, a professor of chemical engineering at Texas A&M University, has been working on a battery that is made of organic substances that can degrade on command. "Many batteries today are not recycled because of the associated energy and labour cost," says Lutkenhaus. "Batteries that degrade on command may simplify or lower the barrier to recycling. Eventually, these degradation products could be reconstituted back into a fresh new battery, closing the materials life-cycle loop."

It's a fair argument considering that, even when a Li battery is dismantled and its parts are refurbished, there will still be some parts that can't be saved and become waste. A degradable battery like the one Lutkenhaus' team is working on could be a more sustainable power source.

The Federal Bureau of Investigation (FBI) warned US companies in a recently updated flash alert that the financially motivated FIN7 cybercriminals group is targeting the US defense industry with packages containing malicious USB devices. BleepingComputer reports: The attackers are mailing packages containing 'BadUSB' or 'Bad Beetle USB' devices with the LilyGO logo, commonly available for sale on the Internet. The packages have been mailed via the United States Postal Service (USPS) and United Parcel Service (UPS) to businesses in the transportation and insurance industries since August 2021 and defense firms starting with November 2021. FIN7 operators impersonate Amazon and the US Department of Health & Human Services (HHS) to trick the targets into opening the packages and connecting the USB drives to their systems. Since August, reports received by the FBI say that these malicious packages also contain letters about COVID-19 guidelines or counterfeit gift cards and forged thank you notes, depending on the impersonated entity.

After the targets plug the USB drive into their computers, it automatically registers as a Human Interface Device (HID) Keyboard (allowing it to operate even with removable storage devices toggled off). It then starts injecting keystrokes to install malware payloads on the compromised systems. FIN7's end goal in these attacks is to access the victims' networks and deploy ransomware within a compromised network using various tools, including Metasploit, Cobalt Strike, Carbanak malware, the Griffon backdoor, and PowerShell scripts. [...] Companies can defend against such attacks by allowing their employees to connect only USB devices based on their hardware ID or if they're vetted by their security team.

An anonymous reader quotes a report from Motherboard: On the eve of the new year, tragedy struck in Manhattan: Chelsea art gallery owner Todd Kramer had 615 ETH (about $2.3 million) worth of NFTs, primarily Bored Apes and Mutant Apes, stolen by scammers and listed on the peer-to-peer NFT marketplace OpenSea. Kramer quickly took to Twitter and begged for help from OpenSea and the NFT community for help regaining his NFTs. Unsurprisingly, he was ripped to shreds by others in the community for not storing his valuable JPEGs in an offline wallet; however, OpenSea froze trading of the stolen NFTs on its platform. More than a few commentators pointed out that OpenSea's intervention here -- and especially Kramer's pleas for a centralized response -- seemed to go against a key tenet of the industry that often bumps up against usability: the idea that "code is law," and once your tokens are in someone else's digital wallet, that's the end of the game. While OpenSea did not actually reverse the transaction on the blockchain, it did block the stolen NFT's sale on its own platform, which is the most popular marketplace for NFTs.

"We take theft seriously and have policies in place to meet our obligations to the community and deter theft on our platform. We do not have the power to freeze or delist NFTs that exist on these blockchains, however we do disable the ability to use OpenSea to buy or sell stolen items. We've prioritized building security tools and processes to combat theft on OpenSea, and we are actively expanding our efforts across customer support, trust and safety, and site integrity so we can move faster to protect and empower our users." OpenSea did not answer, however, why it had frozen the trading of these NFTs and not others stolen just weeks ago that were announced on Twitter by Bored Ape Yacht Club and Jungle Freak NFT owners.

OpenSea's interventions, when they do happen, leave some users in the lurch. For example, another Twitter user recounted in a viral post how they unwittingly purchased a stolen NFT on OpenSea for 1.5 ETH (around $5000) only to have it frozen. OpenSea wasn't quick to help them out, they said -- although, it's unclear what the company could really do at that point -- and the NFT project Alien Frens reimbursed them 1 ETH. In these and other cases, "self-sovereignty" is offered up as an attempt to reframe what actually happened. Yes, the victims are ridiculed for falling prey to a hack or scam, expected to learn from their mistake by using cold storage, and in the best scenario able to buy the NFTs back at a discount because they're not sold on major marketplaces. But at least there was no centralized intervention. Kramer himself was able to buy at least two of his NFTs back with the help of users who had unwittingly bought them from the scammer. OpenSea's interventions in the cases of stolen NFTs show how centralized intermediaries often have an important role wherever the decentralized world of the blockchain meets the real world. It's also not the first time that similar moves have happened elsewhere in crypto, even though they break from the core dogma of immutability and self-sovereignty. "Scams have always been a part of the cryptocurrency industry, and so has the uncomfortable question of centralized interventions," writes Motherboard's Edward Ongweso Jr in closing. "It increasingly feels like the inconsistent application of rules in this space more often results in protecting wealth transfer schemes than protecting all users equally, and obscuring the deep centralization already present: less than one percent of users (institutional investors) account for 64 percent of Coinbase's trading volume (PDF), and 10 percent of traders account for 85 percent of NFT transactions and trade 97 percent of all NFTs at least once."

"It's not clear how this contradiction will be resolved. Uncritically believing decentralization is a salve that immediately transforms something's politics endangers not only users but crypto's fever dream of disruption..."

An anonymous reader quotes a report from BleepingComputer: Accounts of more than three million users of the U.S.-based FlexBooker appointment scheduling service have been stolen in an attack before the holidays and are now being traded on hacker forums. The same intruders are offering databases claiming to be from two other entities: racing media organization Racing.com and Redbourne Group's rediCASE case management software, both from Australia. Among FlexBooker's customers are owners of any business that needs to schedule appointments, which is everything from accountants, barbers, doctors, mechanics, lawyers, dentists, gyms, salons, therapists, trainers, spas, and the list goes on.

Claiming the attack seems to be a group calling themselves Uawrongteam, who shared links to archives and files with sensitive information, such as photos, driver's licenses, and other IDs. According to Uawrongteam, the database contains a table with 10 million lines of customer information that ranges from payment forms and charges to driver's license photos. The actor notes that some "juicy columns" in the database are names, emails, phone numbers, password salt, and hashed passwords. FlexBooker has sent a data breach notification to customers, confirming the attack and that the intruders "accessed and downloaded" data on the service's Amazon cloud storage system. "On December 23, 2021, starting at 4:05 PM EST our account on Amazon's AWS servers was compromised," reads the notification, adding that the intruders did not access "any credit card or other payment card information."

The Biden administration wants to shove more money into projects that are supposed to capture CO2 emissions from power plants and industrial facilities before they can escape and heat up the planet. But carbon capture technologies that the Department of Energy has already supported in the name of tackling climate change have mostly fallen flat, according to a recent report by the watchdog Government Accountability Office. From a report: About $1.1 billion has flowed from the Department of Energy to carbon capture and storage (CCS) demonstration projects since 2009. Had they panned out, nine coal plants and industrial facilities would have been outfitted with devices that scrub most of the CO2 out of their emissions. Once captured, the CO2 can be sent via pipelines to underground storage in geologic formations. That's not what happened. The DOE doled out $684 million to coal six coal plants, but only one of them actually got built and started operating before shuttering in 2020. Of the three separate industrial facilities that received $438 million, just two got off the ground. Without more accountability, "DOE may risk expending significant taxpayer funds on CCS demonstrations that have little likelihood of success," the GAO says.

The Metropolitan Police Department (MPD) has lost two floppy disks containing personal information on 38 people, the department announced on Dec. 27. From a report: The MPD said the floppy disks contained personal data on 38 people who had applied for public housing in Tokyo's Meguro Ward. The ward office had provided the personal information to the MPD to check if the applicants were affiliated with organized crime groups. Police said no leaks or misuse of the information have been confirmed at this point. According to the MPD's third organized crime control division, the names, dates of birth, and sex of 38 men in their 20s to 80s who had applied for Meguro Ward-run housing were recorded on the floppy disks. None of them were apparently affiliated with gangs. The police division and Meguro Ward signed an agreement in 2012 to check whether public housing applicants were affiliated with crime syndicates. Police received the floppy disks from the ward in December 2019 and February 2021 to conduct background checks, and kept them in the division's locked storage. The loss of the disks emerged after a Meguro Ward employee made a new inquiry to the police division on Dec. 7 and police went back to the disks to return them. Police say the disks may have been discarded accidentally.

Swedish battery manufacturer Northvolt announced that on December 28th, it successfully produced the first lithium-ion battery cell to be designed, developed, and built completely in Europe by a homegrown company. Teslarati reports: "Last night, the commissioning of the Northvolt Ett gigafactory in northern Sweden led to the assembly of the first battery cell," Northvolt wrote. The company's factory, located in Vasteras, Sweden, is the first factory in Europe to have a cell that has been "fully designed, developed and assembled at a gigafactory by a homegrown European battery company," the company added. The production of the cell is a massive milestone for Northvolt, which has been working to get its gigafactory up and running since 2017. The company said the cell is of a prismatic cell format, which consist of large sheets of anodes, cathodes, and separators sandwiched, rolled up, and pressed to fit into a metallic or hard-plastic housing in cubic form, according to AllAboutCircuits.

Northvolt Labs in Vasteras has been in production since early 2020, the company said. Northvolt plans to expand the production capacity of the facility toward 60 GWh per year, which will fulfill over $30 billion worth of contracts the battery maker has already locked up with various automotive manufacturers, including BMW, Volkswagen, Volvo, Polestar, Fluence, and Scania. Northvolt Ett will commercially deliver various cell types in 2022. While the company is based in Europe and has various partnerships with European automotive and energy storage companies, it has no plans to only service entities that are only located on the same continent.

A Forbes associate editor covering privacy, cybercrime, and security/surveillance reports on a recently-revealed search warrant.

Instead of investigating a photo, it asked Google to provide information on a suspect who allegedly owned graphic illegal cartoons involving children: That kind of content is potentially illegal to own under U.S. law and can be detected by Google's anti-child sexual material (CSAM) systems, a fact not previously discussed in the public domain, the warrant reveals.... Google also uses machine learning tools to look at files and analyze them for any sign they're of abused children....

As per its legal requirements, Google handed information on what it found, as well as the IP addresses used to access the images, to the National Center for Missing and Exploited Children (NCMEC), which then passed on the findings to the DHS Homeland Security Investigations unit. Investigators used the IP addresses provided by Google to identify the suspect as the alleged owner of the cartoons, and searched his Google account, receiving back information on emails to and from the defendant. It appears the suspect may actually be a known artist. As no charges have been filed, Forbes isn't publishing his name, but the man identified in the warrant had won several small Midwest art competitions, and one artwork from the 1990s had been mentioned in a major West Coast newspaper...

Google, meanwhile, has in recent years released transparency reports showing how many times it reports issues to NCMEC. The figures reveal a disturbing trend. In the first six months of 2021, it found more than 3.4 million pieces of potentially illegal content in 410,000 separate reports. That was up from 2.9 million in 365,000 reports in the last six months of 2020, and well over double that from January to June 2020, when 1.5 million pieces of CSAM material were discovered and reported to NCMEC in 180,000 reports...

As Google doesn't end-to-end encrypt its communications tools like Gmail or its file storage tech like Drive, it's still possible for the tech company to scan for illegal content. And as it has no plans to introduce those features, law enforcement can still rely on Google to warn NCMEC when abuse happens on its servers. Whether the majority of users will want Google to scan people's accounts so it can help find child abusers, or have improved privacy with end-to-end encryption instead, the Mountain View, California-based business will have to struggle with that balance in perpetuity. The same goes for any one of its rivals.

Heating plasma fuel to over 100 million degrees Celsius to create inexpensive and unlimited zero-emissions electricity "has been compared to everything from a holy grail to fool's gold..." writes the Boston Globe, "or an expensive delusion diverting scarce money and brainpower from the urgent needs of rapidly addressing climate change." [N]ow, after breakthroughs this year at MIT and elsewhere, scientists — and a growing number of deep-pocketed investors — insist that fusion is for real and could start sending power to electricity grids in about a decade.

To prove that, Commonwealth Fusion Systems, an MIT spinoff in Cambridge, is using a whopping $1.8 billion it raised in recent months from investors such as Bill Gates, Google, and a host of private equity firms to build a prototype of a specially designed fusion reactor on a former Superfund site in Devens. A host of excavators, backhoes, and other heavy machinery are clearing land there and laying concrete foundations on 47 acres of newly acquired land. "It may sound like science fiction, but the science of fusion is real, and the recent scientific advancements are game-changing," said Dennis Whyte, director of MIT's Plasma Science and Fusion Center and cofounder of Commonwealth Fusion Systems. "These advancements aren't incremental; they are quantum leap improvements. . . . We're in a new era of actually delivering real energy systems...."

There are now at least 35 companies trying to prove that fusion can be a practical power source, most of them established in the past decade, according to the three-year-old Fusion Industry Association. The promise of fusion was buoyed with significant developments this year. In May, scientists in China used their own specially designed tokamak to sustain a fusion reaction of 120 million degrees Celsius for 101 seconds, the longest on record. In September, Whyte's team at MIT and his colleagues at Commonwealth Fusion Systems demonstrated that, while using relatively low-cost materials that don't require a large amount of space, they could create the most powerful magnetic field of its kind on Earth, a critical component of the prototype reactor they're building in Devens.

"We have come a long way," said Bob Mumgaard, CEO of Commonwealth Fusion Systems, who compared their advance to similar breakthroughs that made flight possible. "We're a pretty conservative science bunch, but we're pretty confident." With some $2 billion raised in recent years — more than any of the other fusion startups — his company is racing to prove that their prototype, called SPARC, will produce more energy than it consumes in 2025. If they succeed, the company plans to start building their first power plant several years afterward. Ultimately, he said, their goal is to help build 10,000 200-megawatt fusion power plants around the world, enough to replace nearly all fossil fuels. "This is a solution that can scale to the size of the problem that decarbonization requires," he said.
Phil Warburg, a senior fellow at Boston University's Institute for Sustainable Energy, disagrees. "Fusion has been an elusive fantasy for a half-century or more," he tells the Boston Globe. "Along with the technical hurdles, the environmental downsides have not been seriously examined, and the economics are anything but proven... The current wave of excitement about fusion comes at a time when we've barely begun to tap the transformative potential of solar, wind, storage, and energy efficiency — all known to be technically viable, economically competitive, and scalable today. The environmental advocacy community needs to focus on vastly expanding those clean-energy applications, leaving fusion to the scientists until they've got something much more credible to show for their efforts."

But Elizabeth Turnbull Henry, president of the Environmental League of Massachusetts rejected the argument that fusion research detracts from investments in renewables as a "false choice.... We're at a very different moment now, and it's good to have a lot of different horses in the race."

The also article notes that officials at America's Nuclear Regulatory Commission told them federal officials are already holding meetings to discuss how they'd regulate fusion reactors.

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. From a report: In a proof of concept, the team behind the new battery technology has produced the world's longest flexible fiber battery, 140 meters long, to demonstrate that the material can be manufactured to arbitrarily long lengths. The work is described today in the journal Materials Today. [...] The new fiber battery is manufactured using novel battery gels and a standard fiber-drawing system that starts with a larger cylinder containing all the components and then heats it to just below its melting point. The material is drawn through a narrow opening to compress all the parts to a fraction of their original diameter, while maintaining all the original arrangement of parts.

While others have attempted to make batteries in fiber form, [says MIT postdoc Tural Khudiyey, a lead author on the paper], those were structured with key materials on the outside of the fiber, whereas this system embeds the lithium and other materials inside the fiber, with a protective outside coating, thus directly making this version stable and waterproof. This is the first demonstration of a sub-kilometer long fiber battery which is both sufficiently long and highly durable to have practical applications, he says. The fact that they were able to make a 140-meter fiber battery shows that "there's no obvious upper limit to the length. We could definitely do a kilometer-scale length," he says.

The 140-meter fiber produced so far has an energy storage capacity of 123 milliamp-hours, which can charge smartwatches or phones, he says. The fiber device is only a few hundred microns in thickness, thinner than any previous attempts to produce batteries in fiber form. In addition to individual one-dimensional fibers, which can be woven to produce two-dimensional fabrics, the material can also be used in 3D printing or custom-shape systems to create solid objects, such as casings that could provide both the structure of a device and its power source. To demonstrate this capability, a toy submarine was wrapped with the battery fiber to provide it with power. Incorporating the power source into the structure of such devices could lower the overall weight and so improve the efficiency and range they can achieve.

An anonymous reader quotes a report from Popular Science: The Biden administration has pledged to create a carbon-free energy sector by 2035, but because renewable resources generate only around 19 percent of US electricity as of 2020, climate experts warn that our transition to a green grid future needs to speed up. A group of researchers at Stanford led by Mark Jacobson, professor of civil and environmental engineering, has set out to prove that a 100 percent renewable energy grid by 2050 is not only feasible but can be done without any blackouts and at a lower cost than the existing grid. Jacobson is the lead author of a new paper, published in Renewable Energy, which argues that a complete transition to renewable energy -- defined as wind, water, and solar energy -- would benefit the US as a whole and individuals by saving costs, creating jobs, and reducing air pollution and carbon emissions.

They modeled how wind turbines, tidal turbines, geothermal and hydroelectric power plants, rooftop and utility photovoltaic panels, and other sources could generate energy in 2050. A host of different sources powered these projections: Jacobson used data from a weather-climate-air pollution model he first built in 1990, which has been used in numerous simulations since. Individual state and sector energy consumption was taken from the Energy Information Administration. Current fossil fuel energy sources were converted to electric devices that are powered by wind, water, and solar. This was then used to create projections for energy use in 2050. Time-dependent energy supply was matched with demand and storage in a grid integration model for every 30 second interval in 2050 and 2051. The study authors analyzed US regions and countrywide demand until the model produced a solution with what the authors called zero-load loss -- meaning, essentially, no blackouts with 100 percent renewable energy and storage. According to Jacobson, no other study is conducting this kind of modeling, which is unique in part because it checks conditions for any simulation every 30 seconds.

As the cost of renewables falls, researchers predict power companies and consumers will migrate to using renewables. Solar and wind are already half the cost of natural gas. Policy may also motivate adoption -- or hinder it. While the current administration has set out goals for a renewable energy grid, new permits for gas and drilling in the Gulf of Mexico counteract those same efforts. [...] The researchers quantified these benefits by looking at private costs, such as those to individuals or corporations, and social ones, which also include health and climate costs. Zero-emissions leads to few air pollution related deaths and illness, and a reduced toll on the healthcare system. [...] The model cannot address emissions from things like long-distance shipping or aviation, though the authors argue that green hydrogen could be a possible alternative to explore. They did not include nuclear energy or carbon capture, which [Anna-Katharina von Krauland, a PhD candidate in the Atmosphere/Energy program at Stanford and a co-author of the paper] views as "distractions from getting to 100 percent renewable energy as quickly as possible" because the technologies are costly, unproven, or lacking in their promises. "The best path forward would be to invest in what we know works as quickly as we can," she says -- such as wind, water, and solar energy.

The UK National Crime Agency has shared a collection of more than 585 million compromised passwords it found during an investigation with Have I Been Pwned, a website that indexes data from security breaches. The Record reports: The NCA now becomes the second law enforcement agency to officially supply HIBP with hacked passwords after the US Federal Bureau of Investigations began a similar collaboration with the service back in May. In a blog post today, Troy Hunt, HIBP creator Troy Hunt said that 225 million of the compromised passwords found by the NCA were new and unique.

These passwords have been added to a section of the HIBP website called Pwned Passwords. This section allows companies and system administrators to check and see if their current passwords have been compromised in hacks and if they are likely to be part of public lists used by threat actors in brute-force and password-spraying attacks. Currently, the HIBP Pwned Passwords collection includes 5.5 billion entries, of which 847 million are unique. All these passwords are also available as a free download, so companies can check their passwords against the data set locally without connecting to Hunt's service.

In a statement shared by Hunt, the NCA said it found the compromised passwords, paired with email accounts, in an account at a UK cloud storage facility. The NCA said they weren't able to determine or attribute the compromised email and password combos to any specific platform or company.

Slashdot reader SoftwareArtist shares an announcement from a Stanford University institute for environmental studies. "For some, visions of a future powered by clean, renewable energy are clouded by fears of blackouts driven by intermittent electricity supplies," the announcement begins.

"Those fears are misplaced, according to a new Stanford University study that analyzes grid stability under multiple scenarios in which wind, water and solar energy resources power 100% of U.S. energy needs for all purposes." "This study is the first to examine grid stability in all U.S. grid regions and many individual states after electrifying all energy and providing the electricity with only energy that is both clean and renewable," said study lead author Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford... Imagine all cars and trucks were powered with electric motors or hydrogen fuel cells, electric heat pumps replaced gas furnaces and water heaters and wind turbines and solar panels replaced coal and natural gas power plants. The study envisions those and many more transitions in place across the electricity, transportation, buildings and industrial sectors in the years 2050 and 2051...

Interconnecting larger and larger geographic regions made power supply smoother and costs lower because it upped the chances of available wind, sun and hydro power availability and reduced the need for extra wind turbines, solar panels and batteries. A significant finding of the study was that long-duration batteries were neither needed nor helpful for keeping the grid stable. Instead, grid stability could be obtained by linking together currently available batteries with storage durations of four hours or less. Linking together short-duration batteries can provide long-term storage when they are used in succession. They can also be discharged simultaneously to meet heavy peaks in demand for short periods. In other words, short-duration batteries can be used for both big peaks in demand for short periods and lower peaks for a long period or anything in-between.
Other findings:

• Cleaner air would spare about 53,200 people from pollution-related deaths every year. It would also spare millions more from pollution-related illnesses. Total estimated health costs saved each year: $700 billion.
• Building and operating a completely renewable grid may create 4.7 million long-term jobs.

• Per capita household energy costs were nearly 63% less.

• New electricity generators would occupy about 0.84% of U.S. land (versus roughly 1.3% occupied today by the fossil fuel industry).

Google has announced a new policy for cloud storage service Drive, which will soon begin to restrict access to files deemed to be in violation of the company's policies. TechRadar reports: As explained in a new blog post, Google will take active steps to identify files hosted on its platform that are in breach of either its Terms of Service or abuse program policies. These files will be flagged to their owner and restricted automatically, which means they can no longer be shared with other people, and access will be withdrawn from everyone but the owner. "This will help ensure owners of Google Drive items are fully informed about the status of their content, while also helping to ensure users are protected from abusive content," the company explained.

According to Google, the motive behind the policy change is to shield against the abuse of its services. This broad catchall encompasses cybercriminal activity (like malware hosting, phishing etc.), hate speech, and content that might endanger children, but also sexually explicit material. "We need to curb abuses that threaten our ability to provide these services, and we ask that everyone abide by [our policies] to help us achieve this goal," states Google in its policy document. "After we are notified of a potential policy violation, we may review the content and take action, including restricting access to the content, removing the content, and limiting or terminating a user's access to Google products." Google goes on to say that it may make "exceptions based on artistic, educational, documentary or scientific considerations." As noted by TechRadar, "there is a system to request a review of a decision if someone feels a file has been restricted unfairly, but it's unclear how the process will be handled on Google's end and how long it might take."

Leading chip-maker Intel has stressed that building Metaverse -- at scale and accessible by billions of humans in real time -- will require a 1,000-times increase in computational efficiency from what we have today. Insider reports: Raja Koduri, a senior vice president and head of Intel's Accelerated Computing Systems and Graphics Group, said that our computing, storage and networking infrastructure today is simply not enough to enable this Metaverse vision, being popularized by Meta (formerly Facebook) and other companies. "We need several orders of magnitude more powerful computing capability, accessible at much lower latencies across a multitude of device form factors," Koduri said in a blog post. To enable these capabilities at scale, the entire plumbing of the internet will need major upgrades, he added.
