Verizon Recalls 2.5 Million Hotspot Devices Due To Fire Hazard (cnbc.com) 12

Verizon is recalling 2.5 million hotspot devices after discovering that the lithium ion battery can overheat, creating a fire and burning hazard. CNBC reports: The recall impacts Ellipsis Jetpack mobile hotspots imported by Franklin Wireless Corp and sold between April 2017 and March 2021. The affected models are labeled: MHS900L, MHS900LS and MHS900LPP. Verizon disclosed the recall Thursday alongside a notice from the U.S. Consumer Product Safety Commission (CPSC). A Verizon spokesperson said just over 1 million of the recalled devices are currently in use, meaning currently or recently used by customers.

According to the recall notice posted by the CPSC, Verizon had received 15 reports of the hotspots overheating. Six of those reports included incidents of fire damage to bedding or flooring and two involved minor burn injuries. Some of the hotspots were supplied to students by their schools to continue remote learning, according to the recall notice. Parents who received hotspots from their children's schools are advised to contact the schools about receiving a replacement. Other customers can request a replacement by going to ellipsisjetpackrecall.expertinquiry.com or calling 855-205-2627.

Lenovo's ThinkPad X1 Nano Weighs Only 1.99 Pounds and Is Powered By Intel Tiger Lake CPUs (hothardware.com) 51

MojoKid writes: The new 13-inch ThinkPad X1 Nano is the thinnest and lightest Lenovo ThinkPad ever in the brand's history. The machine weighs just 1.99 pounds (907 grams), while still sporting a fairly powerful Intel Core i7-1160G7 Tiger Lake quad-core CPU, up to a 1TB NVMe SSD, 16GB of 4267MHz LPDDR4X RAM and a 48 Whr battery. In the benchmarks, the machine holds its own for productivity and content creation tasks as well as a bit of light-duty gaming, versus heavier machines in its peer group. In terms of battery life, the new ThinkPad X1 Nano hangs pretty tough as well, offering about 7.5 hours of constant use up-time with HD video playback. With its 2K (2160X1350 -- 16:10) IPS Dolby Vision-certified display and top tier configuration, it doesn't come cheap, as you might imagine. The ThinkPad X1 Nano has a current starting price of $1,289 and tops out at $2,231 for its most powerful configuration with 1TB of fast SSD storage. Regardless, it's impressive what the machine can deliver in terms of features and performance in its weight class.

Amazon Warns Texas: Don't Pass Bill That Would Drive Up Wind Power Costs (arstechnica.com) 155

Fallout from Texas' statewide power outages in February continues to spread. Today, the Texas House of Representatives is scheduled to debate a bill that would require power producers to bear the costs of services that help keep the electrical grid stable. From a report: If the bill passes, it would "unfairly shift the cost of ancillary electric services exclusively onto renewable generators rather than all the beneficiaries," according to a letter written by the Partnership for Renewable Energy Finance (PREF), an industry group, and signed by Amazon, Berkshire Hathaway Energy, Goldman Sachs, and a number of other firms. Amazon and other big tech firms have invested heavily in renewable power, seeking to spruce up their images while cutting their power bills. Costs for wind and solar have dropped precipitously in recent years, making investments in wind farms and solar plants attractive to power-hungry data center operators like Amazon, Facebook, and Google.

"It is important to note that these changes neither enhance electric reliability nor lower consumer costs," the letter states. "They appear to be premised on the assumption that renewable energy was disproportionately responsible for the state's February power outages, a thesis that has been unequivocally discredited." The bill would require the grid operator, the Electric Reliability Council of Texas (ERCOT), to "directly assign" ancillary service costs to wind and solar power, specifically. The PREF letter counters that not only do all generators utilize ancillary services, but costs for those services have remained flat over the last decade while wind and solar have grown by more than 250 percent.

Saskatchewan To Roll Out $150 Annual Tax For Passenger Electric Vehicles (www.cbc.ca) 215

innocent_white_lamb writes: The Saskatchewan government will implement a new tax for passenger electric vehicles. The announcement was made Tuesday. The new $150 annual tax on passenger electric vehicles (EVs) will take effect Oct. 1, 2021. The government said the reason for this tax is that EVs do not contribute to highway maintenance through the provincial fuel tax. The new tax will be collected when the vehicle is registered. The province says it will continue to examine the future potential for expanding the EV tax to commercial vehicles and inter-jurisdictional trucking. The province will also consider options to apply a tax at EV charging stations.

Great Britain's Electricity System Has Greenest Day Ever Over Easter (theguardian.com) 128

An anonymous reader quotes a report from The Guardian: Great Britain's electricity system recorded its greenest ever day over the Easter bank holiday as sunshine and windy weather led to a surge in renewable energy. The power plants generating electricity in England, Scotland and Wales produced only 39g of carbon dioxide for every kilowatt-hour of electricity on Monday, according to National Grid's electricity system operator, the lowest carbon intensity recorded since National Grid records began in 1935.

On Easter Monday, wind turbines and solar farms generated 60% of all electricity as households enjoyed a bank holiday lunch. At the same time the UK's nuclear reactors provided 16% of the electricity mix, meaning almost 80% of the grid was powered from low-carbon sources. The low-carbon power surge, combined with lower than average demand for electricity over the bank holiday, kept gas-fired power in Great Britain to 10% of the electricity mix and caused the "carbon intensity" of the electricity system to plummet to its lowest on record.

GM Is Building An Electric Chevy Silverado With 400 Miles of Range (theverge.com) 112

General Motors confirmed it's making an all-electric version of the Chevy Silverado pickup truck with around 400 miles of range on a full charge. The Verge reports: The company did not immediately say when the electric Silverado will go on sale, but GM president Mark Reuss said at an event on Tuesday that the company will also make commercial fleet-focused versions of the truck. The electric Silverado will be made at "Factory Zero," the recently rebranded Detroit-Hamtramck plant dedicated to EVs and AVs that GM is currently retooling at a cost of more than $2 billion. It's the same plant where GM will build the all-electric Hummer SUV and Hummer pickup.

The Silverado EV will undoubtedly be a flagship vehicle of the custom electric vehicle platform GM announced last year, called Ultium. Designed to be modular, the Ultium platform is what will power most of GM's forthcoming electric vehicles. The company has promised the platform will be able to provide as much as 400 miles of range in the biggest configurations, and that the trucks built on Ultium will feature 800-volt architecture that allows for really fast charging.

Intel Launches First 10nm 3rd Gen Xeon Scalable Processors For Data Centers (hothardware.com) 42

MojoKid writes: Intel just officially launched its first server products built on its advanced 10nm manufacturing process node, the 3rd Gen Xeon Scalable family of processors. 3rd Gen Xeon Scalable processors are based on the 10nm Ice Lake-SP microarchitecture, which incorporates a number of new features and enhancements. Core counts have been significantly increased with this generation, and now offer up to 40 cores / 80 threads per socket versus 28 cores / 56 threads in Intel's previous-gen offerings. The 3rd Gen Intel Xeon Scalable processor platform also supports up to 8 channels of DDR4-3200 memory, up to 6 terabytes of total memory, and up to 64 lanes of PCIe Gen4 connectivity per socket, for more bandwidth, higher capacity, and copious IO.

New AI, security and cryptographic capabilities arrive with the platform as well. Across Cloud, HPC, 5G, IoT, and AI workloads, new 3rd Gen Xeon Scalable processors are claimed to offer significant uplifts across the board versus their previous-gen counterparts. And versus rival AMD's EPYC platform, Intel is also claiming many victories, specifically when AVX-512, new crypto instructions, or DL Boost are added to the equation. Core counts in the line-up range from 8 — 40 cores per processor and TDPs vary depending on the maximum base and boost frequencies and core count / configuration (up to a 270W TDP). Intel is currently shipping 3rd Gen Xeon Scalable CPUs to key customers now, with over 200K chips in Q1 this year and a steady ramp-up to follow.

Why Shortages of a $1 Chip Sparked Crisis in Global Economy (bloomberg.com) 117

To understand why the $450 billion semiconductor industry has lurched into crisis, a helpful place to start is a one-dollar part called a display driver. From a report: Hundreds of different kinds of chips make up the global silicon industry, with the flashiest ones from Qualcomm and Intel going for $100 apiece to more than $1,000. Those run powerful computers or the shiny smartphone in your pocket. A display driver chip is mundane by contrast: Its sole purpose is to convey basic instructions for illuminating the screen on your phone, monitor or navigation system. The trouble for the chip industry -- and increasingly companies beyond tech, like automakers -- is that there aren't enough display drivers to go around. Firms that make them can't keep up with surging demand so prices are spiking. That's contributing to short supplies and increasing costs for liquid crystal display panels, essential components for making televisions and laptops, as well as cars, airplanes and high-end refrigerators.

"It's not like you can just make do. If you have everything else, but you don't have a display driver, then you can't build your product," says Stacy Rasgon, who covers the semiconductor industry for Sanford C. Bernstein. Now the crunch in a handful of such seemingly insignificant parts -- power management chips are also in short supply, for example -- is cascading through the global economy. Automakers like Ford Motor, Nissan Motor and Volkswagen have already scaled back production, leading to estimates for more than $60 billion in lost revenue for the industry this year. The situation is likely to get worse before it gets better.

Intel MacBook Pro Owner Adds Water Cooling To Silence Noisy Fans, Boost Performance (macrumors.com) 48

An inventive MacRumors forums member has successfully retrofitted a water-cooling system to their 15-inch Intel-based MacBook Pro, thereby eliminating fan noise and boosting performance. From the report: MacRumors forums member "theodric" explained that the noise of their MacBook Pro's fans had become disruptive during conference calls, so amid ordering an M1 MacBook Air, they decided to fit a water cooling system to their machine. theodric used inexpensive parts such as Bitcoin ASIC miner blocks from AliExpress, an Aquastream XT Ultra water pump, and a Zalman radiator and reservoir from 2005 to create the system.

High-transmissivity thermal pads were added between the case shell and various motherboard components to conduct heat away from the MacBook Pro and into the water cooling system. The thermal shielding from the bottom of the case was also removed, as well as the feet, to ensure full contact with the new cooling plates. The pump, which requires Windows software to operate, was run via a virtual machine, and a Raspberry Pi was used for monitoring. theodric says that they have "hardly heard the fan since I started using it" and have seen benchmark scores significantly improve under the system. See theodric's full post for more information about the ambitious project.

What We're Expecting From Google's Custom 'Whitechapel' SoC In the Pixel 6 (arstechnica.com) 16

An anonymous reader quotes a report from Ars Technica: It sounds like this custom Google SoC-powered Pixel is really going to happen. Echoing reports from about a year ago, 9to5Google is reporting that the Pixel 6 is expected to ship with Google's custom "Whitechapel" SoC instead of a Qualcomm Snapdragon chip. The report says "Google refers to this chip as 'GS101,' with 'GS' potentially being short for 'Google Silicon.'" It also notes that chip will be shared across the two Google phones that are currently in development, the Pixel 6 and something like a "Pixel 5a 5G." 9to5 says it has viewed documentation that points to Samsung's SLSI division (Team Exynos) being involved, which lines up with the earlier report from Axios saying the chip is "designed in cooperation with Samsung" and should be built on Samsung's 5nm foundry lines. 9to5Google says the chip "will have some commonalities with Samsung Exynos, including software components."

XDA Developers says it can corroborate the report, saying, "According to our source, it seems the SoC will feature a 3 cluster setup with a TPU (Tensor Processing Unit). Google also refers to its next Pixel devices as 'dauntless-equipped phones,' which we believe refers to them having an integrated Titan M security chip (code-named 'Citadel')." A "3 cluster setup" would be something like how the Snapdragon 888 works, which has three CPU core sizes: a single large ARM X1 core for big single-threaded workloads, three medium Cortex A78 cores for multicore work, and four Cortex A55 cores for background work. The Pixel 6 should be out sometime in Q4 2021, and Pixel phones always heavily, heavily leak before they launch. So I'm sure we'll see more of this thing soon.
"I think the biggest benefit we'll see from a Google SoC is an expanded update timeline," writes Ron Amadeo. "Android updates go a lot smoother when you get support from the SoC manufacturer, but Qualcomm abandons all its chips after the three-year mark for major updates. This lack of support makes updates significantly harder than they need to be, and today that's where Google draws the line at updates."

"Beyond easier updates, I don't know that we can expect much from Whitechapel," adds Amadeo, noting that lots of Android manufacturers have made their own chips but none of them have been able to significantly beat Qualcomm. "It's hard to be bullish on Google's SoC future when the company doesn't seem to be making the big-money acquisitions and licensing deals that Apple, Qualcomm, and Samsung are making. But at least it's a start."

How Children Beating Up a Robot Inspired a New Escape Maneuver System (ieee.org) 87

Long-time Slashdot reader AmiMoJo quotes a classic article from IEEE Spectrum: A study by a team of Japanese researchers shows that, in certain situations, children are actually horrible little brats^W^W^W may not be as empathetic towards robots as we'd previously thought, with gangs of unsupervised tykes repeatedly punching, kicking, and shaking a robot in a Japanese mall...

The Japanese group didn't just document the bullying behavior, though; they wanted to find clever ways of helping the robot avoid the abusive situations. They started by developing a computer simulation and statistical model of the children's abuse towards the robot, showing that it happens primarily when the kids are in groups and no adults are nearby. Next, they designed an abuse-evading algorithm to help the robot avoid situations where tiny humans might gang up on it. Literally tiny humans: the robot is programmed to run away from people who are below a certain height and escape in the direction of taller people.

When it encounters a human, the system calculates the probability of abuse based on interaction time, pedestrian density, and the presence of people above or below 1.4 meters (4 feet 6 inches) in height. If the robot is statistically in danger, it changes its course towards a more crowded area or a taller person. This ensures that an adult is there to intervene when one of the little brats decides to pound the robot's head with a bottle (which only happened a couple times).

Tesla will Sell 'Green Credits' to Volkswagen in China (reuters.com) 37

Reuters reports: A Volkswagen joint venture in China has agreed to buy green car credits from Tesla to help meet local environmental rules
The deal, the first of its kind to be reported between the two companies in China, highlights the scale of the task Volkswagen faces in transforming its huge petrol carmaking business into a leader in electric vehicles to rival Tesla. Shares in Volkswagen, the world's second-biggest automaker, have soared this year as investors warm to its plans to go electric. But in China, and elsewhere, the German company is still heavily reliant on traditional combustion-engine vehicles.

China, the world's biggest auto market where over 25 million vehicles were sold last year, runs a credit system that encourages automakers to work towards a cleaner future by, for example, improving fuel efficiency or making more electric cars. Manufacturers are awarded green credits that can be offset against negative credits for producing more polluting vehicles.

The VW-venture's gas-powered SUVs and sedans "have so far proved far more popular in China than their electric vehicles," Reuters notes.

MarketWatch adds that "A deal to buy credits from Tesla at a premium represents Volkswagen buoying the margins of one of its fiercest rivals in the electric-vehicle space." According to Swiss bank UBS, Tesla and Volkswagen will be the two global leaders in electric-vehicle sales within the next two years. The analysts expect that Volkswagen will catch up with Tesla in terms of total volume of cars sold as soon as next year, when the two companies could deliver around 1.2 million cars each.

Linus Torvalds Discusses Intel and AMD's New Proposals for Interrupt/Exception Handling (linuxreviews.org) 149

"AMD and Intel have both proposed better ways of doing interrupt and exception handling the last few months," reports LinuxReviews.org.

Then they share this analysis Linus Torvalds posted on the Real World Technologies forum: "The AMD version is essentially "Fix known bugs in the exception handling definition".

The Intel version is basically "Yeah, the protected mode 80286 exception handling was bad, then 386 made it odder with the 32-bit extensions, and then syscall/sysenter made everything worse, and then the x86-64 extensions introduced even more problems. So let's add a mode bit where all the crap goes away".

In contrast, the AMD one is basically a minimal effort to fix actual fundamental problems with all that legacy-induced crap that are nasty to work around and that have caused issues...

Both are valid on their own, and they are actually fairly independent. Honestly, the AMD paper looks like a quick "we haven't even finished thinking all the details through, but we know these parts were broken, so we might as well release this".

I don't know how long it has been brewing, but judging by the "TBD" things in that paper, I think it's a "early rough draft"."

In the article (shared by long-time Slashdot reader xiando), LinuxReviews.org summarizes the state of the conversation today: Torvalds went on to say that while AMD's proposed "quick fix" would be easier to implement for him and others operating system vendors, it's not ideal in the long run. Intel's proposal throws the entire existing interrupt descriptor table (IDT) delivery system under the bus so it can be replaced with what they call a new "FRED event delivery" system. Torvalds believes this is a better long-term solution...

While the pros and cons of Intel and AMD's respective proposals for interrupt and event handling in future processors are worthy of discussion, it's in reality mostly up to Intel. They are the bigger and more powerful corporation. It is more likely than not that future processors from Intel will use their proposed Flexible Return and Event Delivery system. Their next generation processors won't, it will take years not months before consumer CPUs have the FRED technology. Remember, the above-mentioned technical document was published earlier this month [in March]. Things do not magically go from the drawing-board to store-shelves overnight.

Intel isn't going to just hand the FRED technology over to AMD and help them implement it. We will likely see both move forward with their own proposals. Intel will have FRED and AMD will have Supervisor Entry Extensions until AMD, inevitably, adopts FRED or some form of it years down the line.

They also note that Torvalds took issue with a poster arguing that microkernels are more secure than monolithic kernels like Linux. "Bah, you're just parroting the usual party line that had absolutely no basis in reality and when you look into the details, doesn't actually hold up.

It's all theory and handwaving and just repeating the same old FUD that was never actually really relevant."

Other Ways Biden's Infrastructure Plan Could Power America's Shift From Fossil Fuels (msn.com) 243

The Washington Post explains exactly how the new infrastructure plan of U.S President Joe Biden would "turbocharge" America's transition away from fossil fuels: The linchpin of Biden's plan, which he detailed in a speech Wednesday in Pittsburgh, is the creation of a national standard requiring utilities to use a specific amount of solar, wind and other renewable energy to power American homes, businesses and factories... [Including hydropower and nuclear energy.] Biden has said he wants a carbon-free electricity grid by 2035, so the proposed standard will probably be large...

He also plans to ask Congress to provide $174 billion to boost the U.S. market share of electric vehicles and their supply chains, from raw materials to retooled factories. He reiterated that he wants to establish 500,000 electric vehicle charging stations by 2030 and electrify 20 percent of the nation's yellow school buses.

Biden also requested $10 billion for a new Civilian Climate Corps, a name designed to echo President Franklin D. Roosevelt's Civilian Conservation Corps. Biden's version would hire an army of young people to work on projects that conserve and restore public lands and waters, increase reforestation, increase carbon sequestration through agriculture, protect biodiversity, improve access to recreation, and build resilience to climate change...

Biden is also asking for $16 billion to put "hundreds of thousands" of people to work plugging hundreds of thousands of "orphan" oil and natural gas wells that were largely abandoned after their useful life but which now leak methane, a greenhouse gas 20 times more potent than carbon dioxide.

The plan also calls for tax credits for solar panels -- and for companies researching carbon-capture technologies -- as well as new funding tools for power transmission lines. But it also seeks $35 billion to pursue a breakthrough technology (as well as $15 billion for climate-related demonstration projects.

This offers a way to commercialize and scale up today's already-existing innovations for clean energy, an official at the Bill Gates-founded Breakthrough Energy told the Post. He suggested the government's purchasing power could ultimately be crucial in lowering the cost of clean technologies like carbon capture and sustainable aviation fuel, and even the cost of producing hydrogen fuel by splitting water molecules.

Slashdot reader DanDrollette also adds this note from the Bulletin of the Atomic Scientists: The Biden administration announced what the Washington Post calls "an ambitious plan to expand wind farms along the East Coast and jump-start the country's nascent offshore wind industry," with enough windmills to be built that they could power more than 10 million US homes, and cut 78 million metric tons of greenhouse gas emissions...

The Biden administration said it will invest in associated research and development, provide $3 billion in low-interest loans to the offshore wind industry, and fund $230 million in changes to US ports to accommodate the expected influx of shipping and construction... While offshore wind is probably one of the fastest-growing sectors in renewable energy, the United States is still far behind Europe, where windmills are a common sight off the coast and the technology is widely accepted...

MIT Researchers Use Radio Waves To Help Robots Find Hidden Objects (engadget.com) 15

A group of scientists from MIT have equipped a robot with a wrist-mounted camera and an RF reader to help it find hidden objects. "As long an item has an RF tag on it, the robot can find it, even if it's hidden behind things like wrapping paper," reports Engadget. From the report: The team told MIT News the most challenging aspect of developing RF Grasp was integrating both sight and RF vision into its decision-making process. They compare the current system to how you might react to a sound in the distance by turning your head to pinpoint its source. RF Grasp will initially use its RF reader to find tagged objects, but the closer it gets to something, the more it depends on the information it collects through its camera to make a decision. Compared to a robot with only a visual system, RF Grasp can locate and pick up an object in about half as many total movements. It also has the unique ability to clean up and declutter its working space as it goes about its tasks.

The team sees RF Grasp helping companies like Amazon further automate and streamline their warehouses. "Perception and picking are two roadblocks in the industry today," said Associate Professor Alberto Rodriguez, one of the researchers who worked on the project.

Nuclear Should Be Considered Part of Clean Energy Standard, White House Says (arstechnica.com) 274

An anonymous reader quotes a report from Ars Technica: More details have emerged about the climate and energy priorities of President Joe Biden's infrastructure plan, and they include support for nuclear power and carbon capture with sequestration (CCS). In a press conference yesterday with reporters, White House climate adviser Gina McCarthy said the administration would seek to implement a clean energy standard that would encourage utilities to use greener power sources. She added that both nuclear and CCS would be included in the administration's desired portfolio. The clean energy standard adds a climate dimension to the Biden administration's recently announced infrastructure plan, seeking to put the US on a path to eliminating carbon pollution.

"We think a CES is appropriate and advisable, and we think the industry itself sees it as one of the most flexible and most effective tools," McCarthy told reporters. "The CES is going to be fairly robust and it is going to be inclusive." McCarthy did not provide details about how far a CES would go in supporting nuclear power. It's possible that the policy may only cover plants that are currently operating, but it may also extend to include new plants. The former is more likely than the latter, though, given the challenges and costs involved in building new nuclear capacity.
CCS is another technology mentioned, which involves capturing carbon dioxide from power plant exhaust streams and sequestering it underground. "The technology has been condemned for prolonging reliance on fossil fuels, and no commercial power plant in the US currently uses CCS," notes Ars.

McCarthy added that they aren't ruling out a carbon tax or fee to get to net-zero.

Apple Knew It Was Selling Defective MacBook Displays, Judge Concludes (theverge.com) 20

A potential class-action lawsuit will go forward for Apple's fragile 2016 MacBook Pro display cables. Judge Edward Davila ruled that "Apple should have known that they would fail and yet kept selling them anyhow," reports The Verge. It follows a recently-certified class action lawsuit for the MacBook Pro's infamous butterfly keyboards. From the report: "The court finds that the allegations of pre-release testing in combination with the allegations of substantial customer complaints are sufficient to show that Apple had exclusive knowledge of the alleged defect," the judge wrote. [The issue is] sometimes called the "stage light" issue because of how the cable damage would produce those dark spots.

Part of the flexgate controversy is around how Apple addressed the issue when it first got publicity in late 2018 -- first by silently swapping a new, slightly longer cable into newer MacBooks, and only opening up one of its typical free repair programs months after 15,000 users signed a petition and it was called out in the press. The company's been a lot more responsive with issues ever since, such as with this free battery replacement program for a small number of those 2016 and 2017 MacBook Pro laptops that won't charge anymore. Unlike the butterfly keyboard suit, the flexgate one doesn't appear to be a certified class-action lawsuit yet -- but there are now nine different plaintiffs lined up in this single case, and the judge is inviting them to submit a new amended complaint.

Swedish Carbon-Fiber Battery Could Revolutionize Car Design (arstechnica.com) 97

An anonymous reader quotes a report from Ars Technica: Tesla is known to be working on designing new battery modules that also work as structural elements, but the California automaker is fashioning those structural modules out of traditional cylindrical cells. There's a more elegant approach to the idea, though, and a group at Chalmers University of Technology in Sweden led by professor Leif Asp has just made a bit of a breakthrough in that regard, making each component of the battery out of materials that work structurally as well as electrically. The structural battery combines a carbon-fiber anode and a lithium-iron phosphate-coated aluminum foil cathode, which are separated by a glass fiber separator in a structural battery electrolyte matrix material. The anode does triple duty, hosting the lithium ions, conducting electrons, and reinforcing everything at the same time. The electrolyte and cathode similarly support structural loads and do their jobs in moving ions.

The researchers tested a couple different types of glass fiber -- both resulting in cells with a nominal voltage of 2.8 V -- and achieved better results in terms of battery performance with thinner, plain weave. The cells using this construction had a specific capacity of 8.55 Ah/kg, an energy density of 23.6 Wh/kg (at 0.05 C), a specific power of 9.56 W/kg (at 3 C), and a thickness of 0.27 mm. To put at least one of those numbers in context, the 4680 cells that Tesla is moving to have an energy density of 380 Wh/kg. However, that energy density figure for the cylindrical cells does not include the mass of the structural matrix that surrounds them (when used as structural panels). Speaking of structural loads, the greatest stiffness was also achieved with plain glass fiber weave, at 25.5 GPa. Again, to put that number into context, it's roughly similar to glass fiber-reinforced plastic, whereas carbon fiber-reinforced plastic will be around 10 times greater, depending on whether it's resin transfer molding or woven sheets pre-impregnated with resin (known as pre-preg). Professor Asp's group is now working to see if swapping the cathode's aluminum foil for carbon fiber will increase both stiffness (which it should) and electrical performance. The group is also testing even thinner separators. He hopes to reach 75 Wh/kg and 75 GPa, which would result in a cell that is slightly stiffer than aluminum (GPa: 68) but obviously much lighter.

Swiss Robots Use UV Light To Zap Viruses Aboard Passenger Planes (reuters.com) 66

A robot armed with virus-killing ultraviolet light is being tested on Swiss airplanes, yet another idea aiming to restore passenger confidence and spare the travel industry more pandemic pain. Reuters reports: UVeya, a Swiss start-up, is conducting the trials of the robots with Dubai-based airport services company Dnata inside Embraer jets from Helvetic Airways, a charter airline owned by Swiss billionaire Martin Ebner. Aircraft makers still must certify the devices and are studying the impact their UV light may have on interior upholstery, which could fade after many disinfections, UVeya co-founder Jodoc Elmiger said. Still, he's hopeful robot cleaners could reduce people's fear of flying, even as COVID-19 circulates.

Elmiger's team has built three prototypes so far, one of which he demonstrated inside a Helvetic jet at the Zurich Airport, where traffic plunged 75% last year. The robot's lights, mounted on a crucifix-shaped frame, cast everything in a soft-blue glow as it slowly moved up the Embraer's aisle. One robot can disinfect a single-aisled plane in 13 minutes, start to finish, though larger planes take longer. Dnata executives hope airplane makers will sign off on the robots -- Elmiger estimates they'll sell for $15,930 or so -- as governments require new measures to ensure air travelers don't get sick.

TSMC Cancels Chip Price Cuts, Promises $100 Billion Investment Surge (nikkei.com) 50

Taiwan Semiconductor Manufacturing Co. (TSMC) is asking clients to accept higher prices as it ramps up investment to deal with a "structural and fundamental increase" in chip demand. Nikkei Asia reports: C.C. Wei, TSMC's CEO, told clients in a letter seen by Nikkei Asia that the world's biggest contract chipmaker plans to invest $100 billion over the three years through 2023 in advanced semiconductor technologies, according to the letter. TSMC this year announced record high capital expenditure of up to $28 billion for this year alone. "We are seeing a structural and fundamental increase in underlying demand driven by key long-term growth megatrends including 5G and high-performance computing," Wei said in the letter. The Covid-19 pandemic has also transformed the global economy, changing how people work, learn and live, the CEO added.

Wei told clients that TSMC will also "suspend wafer price reductions starting December 31" this year, for four quarters. "We believe that this modest action is the least disruptive option to supply chains so that TSMC can deliver our mission of providing leading semiconductor technologies and manufacturing capability to you in a sustainable manner," Wei said. "The increased capacity will improve supply certainty and help protect complex global supply chains that rely on semiconductors," he said. "We ask for your patience as we expedite the building of new fabs and capacity."

Apple To Build Battery-Based Solar Energy Storage Project in Monterey County (mercurynews.com) 51

Apple said Wednesday that it will build a battery-based renewable energy storage facility in Central California near a solar energy installation that already provides energy for all of its facilities in the state. From a report: Apple said the project will store 240 megawatt-hours of energy, or enough to power more than 7,000 homes for one day. It is located next to the California Flats solar installation in southeastern Monterey County, about 100 miles southeast of Apple's Cupertino, California headquarters. The site sends 130-megawatts of electricity directly to Apple's California facilities during daylight hours but does not provide power during dark hours. Lisa Jackson, Apple's vice president of environment, policy and social initiatives, told Reuters in an interview the company intends to develop what it believes will be one of the largest battery-based storage systems in the United States.

"The challenge with clean energy -- solar and wind -- is that it's by definition intermittent," Jackson told Reuters. "If we can do it, and we can show that it works for us, it takes away the concerns about intermittency and it helps the grid in terms of stabilization. It's something that can be imitated or built upon by other companies."

'Intel 11th-Generation Rocket Lake-S Gaming CPUs Did Not Impress Us' (arstechnica.com) 68

ArsTechnica: Today marks the start of retail availability for Intel's 2021 gaming CPU lineup, codenamed Rocket Lake-S. Rocket Lake-S is still stuck on Intel's venerable 14 nm process -- we've long since lost count of how many pluses to tack onto the end -- with features backported from newer 10 nm designs. Clock speed on Rocket Lake-S remains high, but thread counts have decreased on the high end. Overall, most benchmarks show Rocket Lake-S underperforming last year's Comet Lake -- let alone its real competition, coming from AMD Ryzen CPUs. Our hands-on test results did not seem to match up with Intel's marketing claims of up to 19 percent gen-on-gen IPC (Instructions Per Clock cycle) improvement over its 10th-generation parts. It shouldn't come as an enormous surprise that Core i9-11900K underperforms last year's Core i9-10900K in many multithreaded tests -- this year's model only offers eight cores to last year's 10. On the plus side, Intel's claims of 19% gen-on-gen IPC are largely borne out here, mostly balancing the loss out in Passmark and Geekbench. This year's Core i5 makes a much better showing than its Core i9 big sibling. In Cinebench R20, Core i5-11600K almost catches up with Ryzen 5 5600X, and it easily dominates last year's Comet Lake i5 equivalent. It doesn't catch up to its Ryzen competitor in Passmark or Geekbench multithreaded tests, but it outpaces last year's model all the way around.

'Rectenna' Harvests Electromagnetic Energy From 5G Signals (interestingengineering.com) 127

An anonymous reader quotes a report from Interesting Engineering: In a world-first, a team of researchers at the Georgia Institute of Technology has developed a small, 3D-printed rectifying antenna that can harvest electromagnetic energy from 5G signals and use it to power devices, in a way turning 5G networks into "a wireless power grid," according to a press release by the university. As explained in the Jan.12 issue of the journal Scientific Reports, the flexible Rotman lens-based rectifying antenna, in other words, rectenna, system can perform millimeter-wave harvesting in the 28-GHz band. Commonly used in radar surveillance systems to see multiple directions without moving the antenna system, the Rotman lens is especially important for beamforming networks. However, larger antennas, which unfortunately have a narrowing field of view, are needed to harvest enough power to supply devices, and this limits the usage.

The researchers solved this problem by using a system that has a wide angle of coverage. The Rotman lens provides 6 levels of view at the same time in a pattern shaped like a spider. By enabling this structure to map a set of selected radiation directions to an associated set of beam-ports, the lens is used as an intermediate component between the antennas and the rectifiers. This way, the electromagnetic energy collected by the antenna arrays from one direction is combined and fed into a single rectifier. This maximizes efficiency, enabling a system with both high gain and large beamwidth. The system achieved a 21-fold increase in harvested power compared with a referenced counterpart in demonstrations. It was also able to maintain identical angular coverage.

Apple Watch Can Accurately Assess Frailty, Finds Stanford Study (macrumors.com) 15

The Apple Watch can accurately determine a user's "frailty," according to the findings of a recently-published study from Stanford University. MacRumors reports: Frailty can be determined using a six-minute walking test (6MWT), and the metric is a general standard used to evaluate the functional mobility and exercise capacity of a patient. Higher scores indicate "healthier cardiac, respiratory, circulatory, and neuromuscular function," according to Apple. Conducted by Stanford University researchers and funded by Apple, the study provided 110 Veterans Affairs patients with cardiovascular disease with an iPhone 7 and Apple Watch Series 3. Patients conducted regular at-home six-minute walking tests, which were then compared to their standard in-clinic 6MWT performance.

The study found that an Apple Watch was able to accurately assess frailty with a sensitivity of 90 percent and specificity of 85 percent when supervised in a clinical setting. When assessed in an unsupervised setting at home, the Apple Watch was able to accurately assess frailty with a sensitivity of 83 percent and specificity of 60 percent. The findings indicate that passive activity data gathered by the Apple Watch is an accurate predictor of in-clinic 6MWT performance.

VW Accidentally Leaks New Name For Its US Operations: Voltswagen (cnbc.com) 66

Volkswagen accidentally posted a press release on its website a month early on Monday announcing a new name for its U.S. operations, Voltswagen of America, emphasizing the German automaker's electric vehicle efforts. CNBC reports: The release called the change a "public declaration of the company's future-forward investment in e-mobility." It said Voltswagen will be placed as an exterior badge on all EV models with gas vehicles having the company's iconic VW emblem only. To "preserve elements of Volkswagen's heritage," the release said the company planned to retain the dark blue color of the VW logo for gas-powered vehicles and use light blue to differentiate "the new, EV-centric branding."

The release said Voltswagen of America would remain an operating unit of Volkswagen Group of America and a subsidiary of Volkswagen AG, with headquarters in Herndon, Virginia. Volts are the derived units for electric potential, also known as electromotive force, between two points. General Motors previously used Volt for a plug-in hybrid electric vehicle between 2010 and 2019. The VW press release was incomplete, citing the need for an additional quote and photography from the automaker's plant in Chattanooga, Tennessee.

UPDATE: VW later said the name change was an April Fool's Day prank which had leaked early.

Boston Dynamics' New Robot Doesn't Dance. It Has a Warehouse Job (wired.com) 51

It can't do back flips like Atlas the humanoid robot, nor can it dance or open doors for its friends, like Spot the robotic dog can. Instead, Boston Dynamics' new robot, named Stretch, is going straight to work in a warehouse. Wired: Rolling around on a wheeled base, it's basically a large robotic arm that grabs boxes using vacuum power, and it's designed for tasks like unloading trucks or stacking pallets. If Spot and Atlas are the show-offs in the family, Stretch is the straight-up workhorse. But while these machines all look and move in wildly different ways, they actually share a lot of DNA. Stretch may seem familiar to you, because it's a sort of descendant of another machine that debuted a few years back: Handle. That robot had a similar suction arm, but it balanced on two wheels, like a Segway scooter. Handle would grab a box, scoot backward, turn 90 degrees, and roll away to stack the box somewhere else. It looked neat on video, but in practice the robot needed a lot of room to operate. It could manage unloading boxes from a truck, sure. "But it took a long time," says Kevin Blankespoor, lead of warehouse robotics at Boston Dynamics. "The truck is a pretty confined space. And so for Handle, every time it grabbed the box, it would need to roll back into some space where it could rotate freely without collisions."

Which is all to say: If Handle were a human, it'd be let go. So Boston Dynamics pivoted (sorry) to a new form factor for Stretch that slapped a similar robotic vacuum arm on a base with four wheels. Each wheel can move independently, so the robot can shift side to side or forward and backward to orient itself in, say, the back of a truck. This new base granted Stretch two powers. For one thing, resting on four wheels is a whole lot more energy efficient than trying to constantly balance on two. The same is true for animals: A dog or cat is inherently more stable than a human. (Stretch will get 8 hours of battery life, and clients will have the option to upgrade to a double battery that holds 16 hours of charge.) The second advantage is that Stretch's arm can now pivot around its base, while Handle had to pivot its whole body to turn.
Stretch can shift up to 800 boxes an hour.

New Online Science Fiction Dictionary Pushes Back Origin of the Word 'Robot' to 1920 (archive.org) 44

"Fans of science fiction learned last week that the word 'robot' was first used in 1920 — a full three years earlier than originally thought," according to a blog post at Archive.org. They call it "a major SciFi discovery hiding in plain sight": The "massively important yet obvious" change in date was confirmed with a search of the Internet Archive, which has a digitized first edition of the Czech play, R.U.R. Rossum's Universal Robots, published in 1920. There on the title page, hiding in plain sight in an English-language subtitle to the work, is the earliest known use of the word "robot."

This important piece of information is one of many little-known facts captured in the Historical Dictionary of Science Fiction. The project was completed this year by historian Jesse Sheidlower, who credits two things that enabled him to publish this project, decades in the making. "One, we had a pandemic so I had a lot of enforced time at home that I could spend on it," explained Sheidlower. "The second was the existence of the Internet Archive. Because it turns out the Internet Archive has the Pulp Magazine collection that holds almost all the science fiction pulps from this core period...."

The comprehensive online dictionary includes not only definitions, but also how nearly 1,800 sci-fi terms were first used, and their context over time...

The project began nearly twenty years ago at Oxford English Dictionary as the Science Fiction Citations Project.

Solar Is Cheapest Electricity In History, US DOE Aims To Cut Costs 60% By 2030 (cleantechnica.com) 243

Solar is becoming the cheapest option for new electricity in the world, but there's still room to improve. According to a new cost-reduction target announced today, the U.S. Department of Energy aims to cut utility-scale solar power plant costs by 60% by 2030. CleanTechnica reports: So, how does the DOE intend to help cut solar power costs so much by 2030? First of all, the U.S. DOE's Solar Energy Technologies Office (SETO) sees two materials used in solar cells as critical to this brighter solar future perovskites and cadmium telluride (CdTe). The department is [spending] $63 million to try to help with these solar cell innovation goals. In the DOE's own words:

- $40 million for perovskite R&D: Perovskites are a family of emerging solar materials that have potential to make highly efficient thin-film solar cells with very low production costs. DOE is awarding $40 million to 22 projects that will advance perovskite PV device and manufacturing research and developmentâ"as well as performance through the formation of a new $14 million testing center to provide neutral, independent validation of the performance of new perovskite devices.
- $3 million Perovskite Startup Prize: This new prize competition will speed entrepreneurs' path to commercializing perovskite technologies by providing seed capital for their newly formed companies.
- $20 million for CdTe thin films: The National Renewable Energy Laboratory will set up a consortium to advance cheaper CdTe thin-film solar technologies, which were developed in the United States and make up 20% of the modules installed in this country. This consortium will advance low-cost manufacturing techniques and domestic research capabilities, increasing opportunities for U.S. workers and entrepreneurs to capture a larger portion of the $60 billion global solar manufacturing sector.

"Today's announcement also supports several concentrating solar-thermal power (CSP) projects," the department notes. Here are details from the DOE:

- $33 million for CSP advances: The new funding opportunity also includes funding for improvements to the reliability and performance of CSP plants, which can dispatch solar energy whenever it is needed; identifies new solar applications for industrial processes, which contribute 20% of U.S. carbon dioxide emissions; and advances long-duration thermal-energy storage devices. Long-duration energy storage is critical to decarbonizing the electricity sector and couples well with CSP plants, but the cost must fall by a factor of two to unlock deployment.
- $25 million to demonstrate a next-generation CSP power plant: Sandia National Laboratories will receive funding to build a facility where researchers, developers, and manufacturers can test next-generation CSP components and systems and advance toward DOE's 2030 cost target of 5 cents/kWh for CSP plants.

Apple Considers Launching Rugged Watch For Extreme Sports (bloomberg.com) 18

Apple is considering launching an Apple Watch with a rugged casing aimed at athletes, hikers and others who use the device in more extreme environments, according to people familiar with the matter. Bloomberg reports: The Cupertino, California-based technology giant has internally discussed introducing such a Watch variation later in 2021 or 2022 at the earliest, said the people, who asked not to be identified discussing private matters. If Apple goes ahead this time, the rugged version would be an additional model similar to how Apple offers a lower-cost option called the Apple Watch SE and special editions co-branded with Nike and Hermes International. Sometimes dubbed the "Explorer Edition" inside Apple, the product would have the same functionality as a standard Apple Watch but with extra impact-resistance and protection in the vein of Casio's G-Shock watches.

Progress Continues On Recreating the Babbage Programmable Computer (plan28.org) 12

Long-time Slashdot reader RockDoctor writes: A project to create a working example of [english mathematician and computer pioneer Charles Babbage's] original "steampunk computer," referred to by Babbage as the "Analytical Engine 30," is continuing. The update comes via a "Spring 2021 report" to the Computer Conservation Society.

The main news is that a new series of plans, dating from about 1857 have been found and are being examined for incorporation into the final design. "One remarkable feature is the extension of the Store to 1000 registers, and most intriguingly various methods of mechanically addressing the store contents," reads the update. This would compare well with electronic processor design... not that anyone is expecting this machine, when built, to be blisteringly fast.

Could a steam-powered Analytical Engine support backup DNS services in a post-apocalyptic world? Is this Cloudflare's ultimate plan?

Australians Could Be Charged For Exporting Energy From Rooftop Solar Panels To the Grid (theguardian.com) 210

An anonymous reader quotes a report from The Guardian: Australian households with rooftop solar panels could be charged for exporting electricity into the power grid at times when it is not needed under proposed changes to the national electricity market. The recommendation is included in a draft deliberation by the Australian Energy Market Commission that is designed to prevent "traffic jams" of electricity at sunny times that could destabilize the network.

The commission, which makes the rules for the electricity system, said the change was necessary to allow more household solar systems and batteries to be connected to the grid and make the system fairer for all electricity users. Benn Barr, the commission's chief executive, said it was expected an average solar household with a system of between 4 and 6 kilowatts would still save about $900 a year on power bills after the change, about $70 less than currently. He said it would reduce bills for the 80% of households who do not have solar as they would no longer have to pay for solar export services they were not using.

Samsung Unveils 512GB DDR5 RAM Module (engadget.com) 33

Samsung has unveiled a new RAM module that shows the potential of DDR5 memory in terms of speed and capacity. Engadget reports: The 512GB DDR5 module is the first to use High-K Metal Gate (HKMG) tech, delivering 7,200 Mbps speeds -- over double that of DDR4, Samsung said. Right now, it's aimed at data-hungry supercomputing, AI and machine learning functions, but DDR5 will eventually find its way to regular PCs, boosting gaming and other applications. Developed by Intel, it uses hafnium instead of silicon, with metals replacing the normal polysilicon gate electrodes. All of that allows for higher chip densities, while reducing current leakage.

Each chip uses eight layers of 16Gb DRAM chips for a capacity of 128Gb, or 16GB. As such, Samsung would need 32 of those to make a 512GB RAM module. On top of the higher speeds and capacity, Samsung said that the chip uses 13 percent less power than non-HKMG modules -- ideal for data centers, but not so bad for regular PCs, either. With 7,200 Mbps speeds, Samsung's latest module would deliver around 57.6 GB/s transfer speeds on a single channel.

Researchers Found a Way To Send Tiny Robots Into Mouse Brains (gizmodo.com) 22

An anonymous reader quotes a report from Gizmodo: In a mind-bending development, a team of researchers in China have managed to treat brain tumors in mice by delivering drugs to the tissues using microscopic robots. The robots jumped from the mice's bloodstreams into their brains by being coated in E. coli, which tricked the rodents' immune systems into attacking them, absorbing the robots and the cancer-fighting drugs in the process. The team's research was published today in the journal Science Robotics. It comes on the heels of previous research by members of the same team, which saw liquid-coated nanorobots remotely propelled through the jelly-like fluid of the eye. Besides being an obvious recipe for an episode of "The Magic School Bus," the research had obvious applications for ophthalmological research and medical treatments.

The crafts are magnetic, and the researchers use a rotating magnetic field to pull them around remotely. On microscales -- we're talking incremental movements about 1% the width of a hair -- the researchers were able to make the hybrid bio-bots wend paths like in the video game Snake. They're dubbed "neutrobots" because they infiltrate the brain in the casing of neutrophils, a type of white blood cell. It ultimately took Wu's team eight years to actualize the microscopic robot swarms capable of bridging the gap between the rodent bloodstream in the animal's tail, where the bots were injected, and its brain, where gliomas -- tumors that emerge from the brain's glial cells -- resided. Part of the issue is that the mice's white blood cells didn't dig the flavor of the magnetic robots. To overcome that issue, Wu's team coated the bots in bits of E. coli membrane, which the white blood cells easily recognize as a unwelcome invader. That made the robots much more palatable, and the white blood cells enveloped them. From inside those cells, the robots were then able to roll the cells toward the brain; a Trojan horse for the 21st century (in this case, one that benefits the residents of Troy). The neutrobots made it into the brains and were able to deliver the drug directly to the targeted tumors.

Intel To Outsource Some Key CPU Production for 2023 Chips to TSMC (tomshardware.com) 31

An anonymous reader shares a report: Intel made several big announcements about its 7nm tech at this week's Intel Unleashed: Engineering the Future event and divulged that it expects that the majority of its products in 2023 to still be produced in-house using its own manufacturing technology. But there's a caveat: Intel CEO Pat Gelsinger said the company will also release "leadership CPU products" in 2023 with CPU cores that are fabricated with an unspecified process node from third-party foundry TSMC, and those CPUs will come to both the client and data center markets. This development comes on the heels of Intel's announcement last year that its 7nm process was delayed, possibly forcing it to do the unthinkable -- turn to external foundries to produce its core logic, like CPUs and GPUs, for the first time in the company's history.

The newest announcements mean that, in addition to the 7nm Meteor Lake desktop chips and Granite Rapids data center processors that Intel will produce with its own process technology in 2023, the company will also release other lines of CPUs in 2023 that will use CPU cores with an as-yet-unspecified process node from TSMC. Intel noted that the chips that utilize TSMC's third-party process tech will power Intel's "CPU leadership" products for both the client and data center markets, suggesting a split product stack. Intel says that the majority of its products in 2023 will come manufactured with its own process technology. Still, it's important to note that Intel hasn't specified that the majority of the newly-released 2023 products will come with its own 7nm process. Naturally, Intel will still have plenty of chip production volume centered on its 14nm and 10nm process tech in that timeframe, and even older nodes that still ship in large volumes.

Samsung is Reportedly Working on a Double-Folding Phone (theverge.com) 37

Samsung is reportedly working on a double-folding phone to add to its lineup, according to Nikkei Asia. From the report: According to the article, the phone would fold into three segments using two hinges and could be announced "as early as the end of this year." The phone would be a third option in Samsung's foldable lineup, joining the Galaxy Z Fold and Z Flip, both of which are also expected to appear in new versions this year. According to the report, the design is still being finalized, but Nikkei's sources say its screen could have a more standard 16:9 or 18:9 aspect ratio, making it easier for app makers to design for than the 25:9 screen found on the Z Fold. [...] It's possible that Samsung is introducing the new type of foldable to ease its power users into a transition to the form factor. Samsung says it might be skipping a new Galaxy Note this year but wasn't exactly clear on why. There was talk of streamlining its phone offerings and of the global chip shortage, but this could be a test to see if Note users are ready for the fold. By giving customers three foldable options to choose from, Samsung could be trying to make it as likely as possible that people will find one that works for them.

British Army To Be Reduced By About 10,000 Soldiers As Part of Move Towards Robots, Drones, and Cyber Warfare (bbc.com) 73

An anonymous reader quotes a report from the BBC: The size of the Army is to be reduced to 72,500 soldiers by 2025 as part of a move towards drones and cyber warfare. Defence Secretary Ben Wallace said "increased deployability and technological advantage" meant greater effect could be delivered by fewer people. He set out plans for new capabilities such as electronic warfare and drones in a command paper in the Commons. Labour has warned that "size matters" when it comes to defence.

Announcing a major overhaul of the armed forces, Mr Wallace said it marked a shift from "mass mobilization to information age speed," insisting they must be able to "seek out and understand" new threats to the country's security. A cut to the size of the Army had been anticipated -- with a reduction of 10,000 widely trailed. What Defence Secretary Ben Wallace announced was a cut to the target for the number of fully trained people in the Army, from 82,040 today to 72,500 in 2025. The changes set out in the paper -- titled Defence in a Competitive Age -- include 3 billion pounds for new vehicles, long-range rocket systems, drones, electronic warfare and cyber capabilities.
The UK is putting more resources into cyber warfare via the creation of the National Cyber Force based in the North West of England. It's also putting more resources ($6.6 billion for research and development) into space that may function similarly to the U.S. Space Force.

Can VW's Electric Cars Compete With Tesla's? (nytimes.com) 221

The New York Times reports: Not long ago Volkswagen was a global pariah after pleading guilty to the biggest emissions fraud in automotive history. Now it is the toast of the stock market, with its shares worth twice as much as they were a year ago.

What happened?

Ironically, Volkswagen's misdeeds helped pave the way for its reversal of fortune... The financial commitment Volkswagen made then, when sales of electric vehicles were minimal, is paying off now as the company rolls out a line of vehicles developed from the ground up to run on batteries, with more interior space and more appeal than adaptations of gasoline vehicles... Investors have noticed, lighting up online stock forums with chatter about Volkswagen and rewarding other established carmakers, like General Motors and Ford Motor, that are pivoting to electric propulsion. Shares of Tesla, on the other hand, have slipped. Tesla is still the most valuable car company in the world by a wide margin, but investors are no longer as certain that Tesla will have the fast-growing electric car market to itself...

Volkswagen also benefited from a report issued this month by analysts at UBS, the Swiss bank, which rated it as the traditional carmaker best positioned to compete with Tesla because it already has the ability to mass-produce electric cars economically... With 665,000 employees and sales of 9.3 million vehicles last year, Volkswagen is the second-largest carmaker in the world after Toyota. It can spread the cost of developing new technologies over millions of vehicles and undercut Tesla on price. By 2025, Volkswagen will be able to produce electric vehicles for less than it costs to build a gasoline or diesel car, UBS analysts wrote in this month's report.

They cautioned that Tesla retains a significant lead in battery technology and autonomous driving software.

Sales of electric VW cars tripled last year, to 230,000 vehicles, the article points out — noting that that's just the beginning. This week VW also announced plans to employ 10,000 software engineers to work on new technologies including autonomous driving, becoming the second-biggest software company in all of Europe.

"The diesel scandal remains a financial burden. The company disclosed in its annual report this week that potential liabilities from lawsuits, such as one by shareholders claiming the company misled them, could cost 4.2 billion euros, or $5 billion. That is in addition to the tens of billions of euros Volkswagen has already paid in fines and settlements since 2017 after admitting that it programmed diesel cars to produce lower emissions in testing conditions than in normal use."

But "Investors this week were focusing on Volkswagen's future rather than its past..."

A spokesperson for the University confirmed to Newshub on Thursday that an unexpected issue wiped all files saved on the desktops. "The University's Digital Solutions team continues to work with all affected staff and students to recover access to files and in many cases the issues have been resolved," they said. "There are however, some affected staff and students who have not been able to recover access to files."

The aim of the data wipe was to clear inactive users' data by getting rid of profiles of students who no longer studied, reports student magazine Critic. Critic spoke to one Masters student who had heard of PHD students losing an entire year's worth of data. The university spokesperson said they apologized for the inconvenience caused and is investigating the issue to ensure it doesn't happen again.

US Grid At Rising Risk To Cyberattack, Says GAO 69

Distribution systems within the U.S. electrical grid are increasingly vulnerable to cyberattack, a government watchdog said in a report released Thursday. The Hill reports: In the report, the Government Accountability Office (GAO) noted that the Department of Energy's cybersecurity strategy has predominantly focused on generation and transmission systems. The watchdog recommended further attention to risks facing distribution systems, those parts of the grid that actually carry power directly to customers. Those aspects of the grid, the report states, "are becoming more vulnerable to cyberattacks, in part due of the introduction of and reliance on monitoring and control technologies." "However, the scale of potential impacts from such attacks is not well understood," it states.

Distribution systems' vulnerability is increasing due to their industrial control systems, which have increasingly been incorporating remote access. As a result, they can give bad actors access to them. The systems the report analyzed generally are not covered by federal cybersecurity standards but have in some cases taken independent action on them. Energy Department officials told GAO investigators they were unaware of any assessments underway analyzing how a cyberattack would affect distribution systems, saying the impact would likely be less significant than on generation and transmission. However, the report notes, depending on which distribution was affected it could have nationwide effects.

Windows 10 Updates Are Causing Even More Printer Problems Than First Thought (betanews.com) 70

Following reports that a recent update to Windows 10 was causing blue screens as well as problems with printing, Microsoft issued a new series of updates to address the issues. But it seems that the problems caused by this month's Patch Tuesday updates are actually worse than first thought. BetaNews reports: Users with certain brands of printer experienced APC_INDEX_MISMATCH errors and blue screens, but now Microsoft has issued a warning that there may be additional problems with elements missing from print outs, or even entirely blank pages being output. The problematic updates are KB5000802, KB5000808, KB5000809 and KB5000822. In the support documentation for these four updates, Microsoft acknowledges the APC_INDEX_MISMATCH error problems and BSoDs, and directs people to install the relevant patches for their system. But the company now also acknowledges that there are more problems with the original updates than first appeared to be the case.

For each of these four updates Microsoft issues the same warning: "After installing updates released March 9, 2021 or March 15, 2021, you might get unexpected results when printing from some apps..." There is currently no fix, and Microsoft is not even able to offer a workaround right now. Instead, the company simply says: "We are working on a resolution and estimate a solution will be available in the coming days."

Nissan Finds a Second Use For Old LEAF Batteries (slashgear.com) 59

An anonymous reader quotes a report from SlashGear: Nissan has found a second-life for old LEAF batteries inside mobile machines that help workers at Nissan factories worldwide. The old batteries are being used in automated guided vehicles or AGVs used for various tasks inside the manufacturing facilities, including delivering parts to workers on the assembly line.

AGVs are used as robotic mail carriers operating on magnetic tracks taking mail and parts exactly where they're needed on the assembly line. The idea is to use the AGV to deliver parts so the worker doesn't waste time searching for a component and can stay focused on installing parts. Nissan and other automotive manufacturers have found that AGVs are indispensable when it comes to saving time and increasing productivity on the assembly line. Nissan currently operates more than 4000 AGVs around the world at its various manufacturing facilities. The factories have a system that includes 30-second automatic quick charging to keep battery packs on the electric vehicles topped off and working correctly. AGVs also have sensors that keep them operating on a set route and allow them to stop when needed. They also have wireless communications capabilities that enable them to communicate with each other to avoid collisions.

Nissan says that it has been exploring ways to reuse old LEAF batteries since 2010. The first-generation LEAF used a 24-kilowatt hour battery pack made by combining 48 modules. Nissan said eight years ago, its engineers discovered a way to take three of those modules and repackage them to fit inside the AGV. Last year, the engineers began to repurpose used battery modules instead of using new ones to power the AGVs. The team also found the repurposed LEAF batteries last a lot longer thanks to their lithium-ion design compared to the lead-acid batteries used previously.

Qualcomm Now Owns Nuvia, Aims New CPU Design Resources Directly At Apple (arstechnica.com) 41

An anonymous reader quotes a report from Ars Technica: Qualcomm has wrapped up its $1.4 billion acquisition of silicon design firm Nuvia, a move that will lead to in-house Qualcomm CPU designs. The acquisition should allow Qualcomm to compete with Apple's silicon division and focus on pushing bigger, better ARM chips into the laptop market. The deal was announced in January 2021. Don't feel bad if you've never heard of Nuvia; the company was only founded in 2019 and has never made a product. Nuvia was focused on building server chips, but Qualcomm seems mainly interested in the engineering pedigree here, since the company was founded by three high-ranking engineers from Apple's silicon division. Nuvia's CEO, Gerard Williams, formerly Apple's chief CPU architect for nearly a decade, is now Qualcomm's SVP of engineering.

Apple is famously in the process of dumping x86 Intel CPUs in order to roll out in-house ARM architecture designs across the company's entire laptop and desktop lines. Qualcomm wants to be here to sell chips to all the PC vendors that want to follow suit. Qualcomm's press release immediately aimed its new design resource at the market Apple is upending, saying, "The first Qualcomm Snapdragon platforms to feature Qualcomm Technologies' new internally designed CPUs are expected to sample in the second half of 2022 and will be designed for high-performance ultraportable laptops." The call-out that this acquisition will lead to "internally designed CPUs" is a big deal, since currently, Qualcomm only ships lightly customized, off-the-shelf ARM CPUs.

New Soba Noodle-Making Robot at Japan Train Station Eatery Can Cook 150 Servings an Hour (mainichi.jp) 66

A two-armed robot is helping to prepare soba noodles at an eatery at JR Kaihimmakuhari Station in this Chiba city's Mihama Ward (in Japan), capably boiling the noodles in a strainer, rinsing them and then dipping them in iced water. From a report: The Sobaichi Perie Kaihimmakuhari eatery implemented a collaborative cooking system, with the robot cooking the food and employees adding the dipping sauce or soup and toppings. It is apparently the first time for the cooking robot to be introduced in an actual restaurant setting. Soba stands at railway stations usually have to deal with a constant stream of customers and work under time pressure, resulting in a chronic shortage of human resources. [...] The robot fetches soba noodles from a box with one arm, and places it in a strainer. Then with the other arm, it picks up the strainer and boils the noodles for a minute and 40 seconds, rinses off the viscous film on the surface and then dips the noodles in iced water to bring out their firmness. The robot can cook 150 servings in an hour, substituting the work of about one employee.

Samsung Warns of Severe Chip Crunch While Delaying Key Phone (bloomberg.com) 35

Samsung Electronics warned it's grappling with the fallout from a "serious imbalance" in semiconductors globally, becoming the largest tech giant to voice concerns about chip shortages spreading beyond the automaking industry. From a report: Samsung, one of the world's largest makers of chips and consumer electronics, expects the crunch to pose a problem to its business next quarter, co-Chief Executive Officer Koh Dong-jin said during an annual shareholders meeting in Seoul. The company is also considering skipping the introduction of a new Galaxy Note -- one of its best-selling models -- this year, though Koh said that was geared toward streamlining its lineup.

Google's Second-Gen Nest Hub Will Watch You Sleep (androidpolice.com) 60

Google's second-generation Nest Hub will be able to track your sleep via a Soli radar sensor -- not a camera. "Sleep Sensing" is the highlight feature, though, as "there's still a 7-inch display with a middling 600p resolution, a rear-facing fabric-covered speaker, and the device sensors poking through the otherwise uniform bezel," reports Android Police. From the report: According to Google, about 20 percent of first-gen Nest Hubs were placed in bedrooms, and the new Nest Hub can only show its full capabilities when you put it next to your bed. The lack of a camera is actually a selling point here as it ensures a certain degree of privacy. The Hub won't be able to see you, but it still kind of "sees" with radar waves. The Soli radar module creates a bubble where the Hub can track your breathing and movement overnight. Google says Soli in the Hub is accurate enough to detect the general shape and position of a person, but not specific faces or bodies. Combined with temperature and light levels, the Nest Hub can track your sleep and feed that data into Google Fit. Over time, Sleep Sensing can offer actionable tips to improve your sleep, too. This is similar to what you get with various fitness trackers and smartwatches that have sleep monitoring features, but you never have to worry about forgetting to wear your device to bed.

Google says the raw Soli data (above) never leaves your Hub -- machine learning enhancements allow the smart display to do all the processing locally to further preserve your privacy. Soli also supports some basic gestures like holding your hand up to pause media or waving to snooze an alarm. Sleep Sensing will be a free feature at launch, but Google is planning to make it a paid add-on in the future.

Intel Launches 11th-Gen Rocket Lake-S CPUs (venturebeat.com) 91

The new generation of Intel Core CPUs is here. Intel is using a new architecture on its ancient 14nm process to power the 11th-generation Rocket Lake-S processors. From a report: That results in some significant power improvements, but it also means that Intel can only fit 8 cores on its flagship Core i9-11900K. That sacrifice to the number of cores looks bad compared to the 12-core AMD Ryzen 9 5900X or even the last-gen 10-core i9-10900K. But Intel is also promising massive improvements to efficiency that should keep the Rocket Lake-S parts competitive -- especially in gaming. Rocket Lake-S CPUs launch March 30. The $539 Core i9-11900K has 8 cores and 16 threads with a single-core Thermal Velocity boost of 5.3GHz and 4.8GHz all-core boost. The slightly more affordable $399 i7-11700K boosts up to 5GHz, and the i5-11600K is $262 with 6 cores at a 4.9GHz boost.

While the lack of cores is going to hurt Rocket Lake-S CPUs in multi-threaded applications, Intel claims that its 19% improvement to instructions per clock (IPC) will make up much of the difference. The UHD graphics processor in the CPUs also deliver 50% better performance than last generation. Of course, Intel is focusing on games because that is where its processors remain the most competitive versus AMD. And that should continue with its Rocket Lake-S chips. These high-clocked parts with improved performance should keep up and even exceed AMD's Zen 3 chips in certain games, like Microsoft's Flight Simulator (according to Intel).

Cricut Decides To Charge Rent For People To Fully Use the Cutting Machines They Already Own (hackaday.com) 174

An anonymous reader quotes a report from Hackaday: Probably the best known brand of cutter comes from Cricut, and that company has dropped a bombshell in the form of an update to the web-based design software that leaves their now very annoyed users with a monthly upload limit of 20 new designs unless they sign up for a Cricut Access Plan that costs $9.99 on monthly payments. Worse still, a screenshot is circulating online purporting to be from a communication with a Cricut employee attempting to clarify matters, in which it is suggested that machines sold as second-hand will be bricked by the company.

We'd like to think that given the reaction from their online community the subscription plan will backfire, but unlike the world of 3D printing their market is not necessarily an online-savvy one. A crafter who buys a Cricut from a bricks-and-mortar warehouse store and uses it with Cricut cartridges may not balk at being required to pay rent to use hardware that's already paid for in the same way a member of our community with a 3D printer would. After all, Cricut have always tried to make their software a walled garden. However if the stories about second-hand models being bricked turn out to bear fruit that might be a different matter.
UPDATE 3/18/21: Cricut has decided to reverse its decision and allow every member to upload an unlimited number of images and patterns for free.

"Right now, every member can upload an unlimited number of images and patterns to Design Space for free, and we have no intention to change this policy," a Cricut spokesperson told us in an email. "This is true whether you're a current Cricut member or are thinking about joining the Cricut family before or after December 31, 2021."

They addressed these changes in a letter to the Cricut community, which you can read here.

Researchers In Switzerland Get Electricity From Wood (electrek.co) 47

fahrbot-bot shares a report from Electrek: Researchers at ETH Zurich and Empa have chemically modified wood and made it more compressible, turning it into a mini-generator. When compressed, it generates an electrical voltage. Such wood could serve as a biosensor or as a building material that harvests energy.

Ingo Burgert and his team at public research university ETH Zurich and Swiss federal laboratory Empa have proven that wood is much more than just a building material. Their research enhances the properties of wood in order to use it for new applications. For instance, they have already developed high-strength, water-repellent, and magnetizable wood. Now, together with the Empa research group led by Francis Schwarze, the team has used one chemical and one biological process to generate electrical voltage from a type of wood sponge. In doing so, they amplify what is known as the "piezoelectric effect" of wood.
The findings appear in the journal Science Advances.
