Qualcomm Unveils the First 10-Gigabit 5G Modem (engadget.com) 12

Qualcomm has unveiled the X65, what it says is the "world's first" 10-gigabit 5G modem. Engadget reports: While that's not hugely faster than the 7.5Gbps of the X60, it promises a speed that was previously reserved for Ethernet and other wired connections. The X65 also boasts some helpful functional improvements, including AI-based antenna tuning that better responds to hand grips. You'll also find better power-saving measures and a newer "Smart Transmit" system that boots upload speeds and overall coverage.

The X65 is currently sampling to customers and should reach shipping devices in 2021, although Qualcomm didn't name customers. Don't count on it reaching many phones, at least not at first. [...] While it will support "premium smartphone experiences," you're more likely to see it used in laptops, fixed 5G broadband or similar areas where a separate modem isn't an issue.

The iPhone 12 Mini Was Apple's 2020 Sales Flop (arstechnica.com) 73

An anonymous reader quotes a report from Ars Technica: Bad news for lovers of smaller phones: the iPhone 12 mini has sold poorly compared to other phones in the iPhone 12 lineup -- poorly enough that analysts wonder whether Apple will remain committed to the smaller phone design moving forward. A data firm called Counterpoint Research found that the iPhone 12 mini accounted for just 5 percent of overall sales from the company's smartphone lineup in early January. And J.P. Morgan analyst William Yang told Reuters that screens under 6 inches now account for only 10 percent of smartphones sold industry-wide.

The data from Counterpoint is not the first to tell this story. Consumer Intelligence Research Partners (CIRP) broke down iPhone 12 lineup sales in detail last month. They found that the iPhone 12 Pro and 12 Pro Max made up about 20 percent of sales from the larger iPhone 12 lineup during the launch window, while the non-Pro, 6.1-inch iPhone 12 accounted for 27 percent. But they also said the iPhone 12 mini "likely disappointed Apple" with only 6 percent of sales during the period measured -- pretty close to the number Counterpoint shared a couple of months later.

While all this data shows that the iPhone 12 mini has underperformed, it doesn't tell us why. According to CIRP's data, the also-small iPhone SE performed a little better (likely due to its significantly lower price) but it still didn't make up a huge chunk of sales. So while it's possible that the iPhone 12 mini's slow sales are partially a result of cannibalization by the cheaper SE, small phones are clearly not doing well in general. There are a lot of reasons small phones are less popular now. For one thing, users are consuming more rich media content. Many people watch as much TV and film on their phones as they do on their TVs now, and some social media platforms like TikTok and Snapchat are focused on rich media that may be more enjoyable to some on a larger display. But if anything, these sales numbers make the future of one-handed smartphones look even dimmer than before.

Aurora 7 Laptop With 7 Screens Unveiled (gizmodo.com) 52

Sometimes one screen isn't enough and you need two. Sometimes even two doesn't get the job done, and you need three. If your job requires seven screens, a UK firm now has you covered. Gizmodo reports: The Aurora 7 laptop seems lifted straight from the imagination of a Hollywood prop builder working on a bad hacker flick. But with seven foldout screens, there's little chance anyone could actually use this beast on their laps. It's a mobile transforming workstation for those who need more screen real estate than they have room for monitors. Created by a UK company called Expanscape, the Aurora 7 is very much just a prototype at this stage in the game (as is evident by the extensive use of 3D-printed parts), but it's designed to be true mobile workstation for everyone from developers to content creators to even well-funded gamers wanting a more immersive experience from a computer they don't have to leave at home. Powered by an Intel i9 9900K processor backed by 64GB of DDR4 RAM and an NVIDIA GTX 1060 series graphics card, the Aurora 7 also comes with 2TB of hard drive storage and an additional 2.5 TB of SSD storage, plus all the ports you could ever need to expand its capacity even further. But the star of the show is the complicated mosaic of screens which includes four 17.3-inch 4K (3840 x 2160) LCDs -- two in portrait mode and two in landscape -- as well as three smaller 7-inch screens all pushing 1920 x 1200 pixels, with one located in the laptop's wrist rest. The laptop has a battery life of one hour. No word on pricing or when it starts shipping.

German Institute Develops 'Powerpaste' That Stores Hydrogen Energy At 10x the Density of a Lithium Battery (hackaday.com) 124

A German research organization has developed a magnesium-based "Powerpaste" with an energy density ten times more than current battery technology. Hackaday reports: We've been promised hydrogen-powered engines for some time now. One downside though is the need for hydrogen vehicles to have heavy high-pressure tanks. While a 700 bar tank and the accompanying fuel cell is acceptable for a city bus or a truck, it becomes problematic with smaller vehicles, especially ones such as scooters or even full-sized motorcycles. The Fraunhofer Institute wants to run smaller vehicles on magnesium hydride in a paste form that they call POWERPASTE.

The idea is that the paste effectively stores hydrogen at normal temperature and pressure. At 250C, the paste decomposes and releases its hydrogen. While your motorcycle may seem hot when parked in the sun, it isn't getting quite to 250C. Interestingly, the paste only provides half the available hydrogen. The rest is from water added start a reaction to release the hydrogen. Fraunhofer claims the energy density available is greater than that of a 700 bar tank in a conventional hydrogen system and ten times more than current battery technology.

One thing that's attractive is that the paste is easy to store and pump. A gas station, for example, could invest $20-30,000 and dispense the paste from a metal drum to meet low demand and then scale up as needed. A hydrogen pumping setup starts at about $1.2 million. Fraunhofer is building a pilot production plant that will produce about four tons of the material a year.

Intel Benchmarks Say Apple's M1 Isn't Faster (pcworld.com) 260

PCWorld reviews Intel's recently-released benchmarks claiming Apple's M1 isn't faster than their 11th gen Core i7-1185G7 processor, among other things. Here are the claims Intel makes (visit the article to read PCWorld's "take" on each claim): MacBook M1 is slower than Core i7: Intel says in the WebXPRT 3 test, using the same version of Chrome for both the Core i7 system as well as the Arm-native MacBook, Intel takes the lead. The Intel chip was largely ahead in WebXPRT 3, and the x86 chip was nearly three times faster in finishing the photo enhancement test. Intel doesn't just use WebXPRT 3, though. It also shows the Core i7 pummeling the M1 in a PowerPoint-to-PDF export, and in multiple Excel macros by a factor of 2.3x. And yes, Intel used the Arm-native versions of Office for its tests.

Core i7 Crushes M1 in AI: For content creation tasks, Intel showed the Core i7 to be about 1.12x faster than the M1 in performing a 4K AVC-to-HEVC/H.265 file conversion. In this benchmark, they had the MacBook using the M1-native version of Handbrake. But the real destruction happens once you get to Topaz Lab's Gigapixel AI and Denoise AI, with the Intel Core chip crushing the M1 in AI-based noise removal and enlargement. Or maybe "crushing" is too nice a term, as it's more like the Core i7 outpaces the M1 by so much, the M1 wishes it had never been designed.

M1 doesn't support all the features: Intel also gives itself the lead in Adobe Premiere Pro, using the beta M1 native version in Auto Reframe, exporting to H.264 and H.265. They're decent wins, but come on, the code is still in beta for the Mac. That said, Intel points out that important features like Content Aware Fill are outright disabled on the beta version, and that's a concern. If the native version of Photoshop comes out, and there are critical features missing from it, that's a huge problem for Apple (and Adobe).

You can't be faster if you can't run it: For gaming, we see a bit of a back and forth between the Apple M1 and Core i7 in games that actually work on the MacBook. Intel doesn't let it end there, though, and decides to embarrass Apple further by showing the numerous games where the MacBook scores a 0 because game support just doesn't exist. Intel points out that "countless more" games "don't run on the M1," and then for good measure, it rushes Apple's bench with a list 10 more games you can't play on the M1 MacBook: Overwatch, Crysis Remastered, Halo MCC, Red Dead Redemption 2, PUBG, Monster, Hunter World, Doom Eternal, Microsoft Flight Simulator 2020, Apex Legends, and Rainbow Six Siege.

MacBook wouldn't win Evo certification: You know that fancy Intel Evo program that tries to improve laptop performance in key areas that annoy consumers? Well, Intel pretty much says that if Apple submitted the M1 MacBook to the same program that Asus, Dell, HP, Lenovo, MSI, Acer and others go through, it would be rejected. The reason? Intel says the M1 MacBook is too slow in doing things that anger consumers, such as "switch to Calendar" in Outlook, "start video conference Zoom" and "select picture menu" in PowerPoint.

Great battery life?: Perhaps the most shocking claim Intel showed deals with battery life. While performance tests can be cherry picked by those looking to prove an outcome, battery life usually can't be disputed. Apple's official claim gives the M1 MacBook up to 18 hours of battery life using Apple TV app to watch a 1080p video with the brightness set to "8 clicks from the bottom." Apple also claims up to 15 hours browsing 25 "popular" websites with the same "8 clicks" criteria. When Intel pitted a MacBook Air M1 against an Acer Swift 5 with a Core i7-1165G7, however, it found both basically dead even. The MacBook Air came in at 10 hours and 12 minutes, and the Acer Swift 5 lasted 10 hours and 6 minutes. The difference? Intel said it used Safari to watch a Netflix stream with tabs open with the screen set to a relatively bright 250 nits. On the Acer, Safari was subbed out for Chrome, but the brightness and Netflix remained the same. Intel did add that Apple's "8 clicks up" is about 125 nits of brightness on the MacBook Air which is pretty dim.

All kinds of things just don't work on the M1: Intel didn't just get into the performance of the M1. It also said it found the MacBook Pro had serious shortcomings, such as an inability to use more than one display with a Thunderbolt dock. And while the PC can use gaming headsets, eGPUs, a third-party finger print reader, Wacom Drawing tablet and Xbox Controller, Intel said it found the MacBook Pro simply doesn't work with eGPUs, and had multiple issues with other devices. That's just hardware incompatibility. Intel's rap battle with Apple also highlights issues with plug-ins for Ableton, Bitwig Studio, Avid Pro Tools, FL Studio, Motu and many others.

MIT Is Building a 'One-Stop Shop' For 3D-Printing Robots (techcrunch.com) 6

An anonymous reader quotes a report from TechCrunch: MIT's CSAIL department this week showcased "LaserFactory," a new project that attempts to develop robotics, drones and other machines than can be fabricated as part of a "one-stop shop." The system is comprised of a software kit and hardware platform designed to create structures and assemble circuitry and sensors for the machine.

A more fully realized version of the project will be showcased at an event in May, but the team is pulling back the curtain a bit to show what the concept looks like in practice. Here's a breakdown from CSAIL's page: "Let's say a user has aspirations to create their own drone. They'd first design their device by placing components on it from a parts library, and then draw on circuit traces, which are the copper or aluminum lines on a printed circuit board that allow electricity to flow between electronic components. They'd then finalize the drone's geometry in the 2D editor. In this case, they'd use propellers and batteries on the canvas, wire them up to make electrical connections, and draw the perimeter to define the quadcopter's shape."
For more information, CSAIL has released an accompanying video showing the machine in action. A technical paper is available here.

First 3D-Printed House Goes On Sale, Foreshadowing Faster, Cheaper Homebuilding (cnn.com) 134

"A company says it has listed the first 3D printed house in the United States for sale," reports CNN. "This is the future, there is no doubt about it," says Kirk Andersen, the director of operations at SQ4D Inc.

SQ4D uses automated building methods, or 3D printing, to build structures and homes... The company can set up its Autonomous Robotic Construction System at a build site in six to eight hours. It then lays concrete layer by layer, creating footing, the foundation of a house and the interior and exterior walls of the structure... "The cost of construction is 50% cheaper than the cost of comparable newly-constructed homes in Riverhead, New York, and 10 times faster," said Stephen King, the Zillow Premier agent who has the 3D house listing...

"I want people to not be afraid of automation...it is just a different tool and different method. But it's still the same product; we are still building a house at the end of the day," says Kirk Andersen, the director of operations at SQ4D...

"We can make things more affordable and safer. We can use the technology to tackle homelessness, and aid in disaster relief in an eco-friendly way," Andersen said.

Denmark Strikes Deal On Artificial Wind Energy Island (theguardian.com) 48

An anonymous reader quotes a report from The Guardian: Denmark's government has agreed to take a majority stake in a 25 billion euro artificial "energy island," which is to be built 50 miles (80km) offshore, in the middle of the North Sea. The island to the west of the Jutland peninsula will initially have an area of 120,000 sq meters -- the size of 18 football pitches -- and in its first phase will be able to provide 3m households with green energy. It will be protected from North Sea storms on three sides by a high sea wall, with a dock for service vessels taking up the fourth side.

In a broad deal struck on Wednesday night, the Social Democrat government agreed with its support parties and the rightwing opposition that the state should hold a 51% stake in the island, with the remainder held by the private sector. The project builds on an inter-party deal struck in June on energy policy, in which the parties agreed to construct two wind energy hubs, one artificial and another centered on the Baltic island of Bornholm. The two hubs will initially support 5GW of wind generation and triple Denmark's current installed offshore wind. The capacity will later be expanded to as much as 12GW.

IBM Quantum Computers Now Finish Some Tasks In Hours, Not Months (engadget.com) 34

IBM has found a way to combine a new program execution environment, Qiskit, with a balance of "classical" and quantum computing to deliver a 100 times speedup for tasks that depend on iterative circuit execution. Computations that take months now will take mere hours, IBM said. Engadget reports: Qiskit by itself allows more circuits to run at a "much faster" rate, and can store quantum programs so that other users can run them. However, it also uploads programs to conventional hardware sitting next to the quantum machines. Before you ask, this isn't really cheating -- the move is meant to cut the latency between a user's computer and the quantum chip.

IBM expects to release Qiskit sometime in 2021. Its roadmap also has quantum systems handling a wider range of circuits, and thus a wider range of computing challenges, by 2022. New control systems and libraries in 2023 will help IBM reach its goal of running systems with 1,000 or more qubits, taking the company closer to a "quantum advantage" where the technology can handle at least some tasks more efficiently or cost-effectively than traditional hardware.

Mac Utility Homebrew Finally Gets Native Apple Silicon and M1 Support (arstechnica.com) 43

An anonymous reader quotes a report from Ars Technica: Homebrew now supports Apple Silicon natively, albeit not with every package. The volunteer Homebrew team made the announcement on the Homebrew blog alongside today's release. While the native support is not yet comprehensive, it bridges the gap significantly, and users can still run Terminal via Rosetta 2 to do what they can't yet while running natively on Apple Silicon. The Homebrew blog post says "we welcome your help" in providing bottles for all packages moving forward.

Here's the full bullet point on Apple Silicon in the Homebrew 3.0.0 release notes: "Apple Silicon is now officially supported for installations in /opt/homebrew. formulae.brew.sh formula pages indicate for which platforms bottles (binary packages) are provided and therefore whether they are supported by Homebrew. Homebrew doesn't (yet) provide bottles for all packages on Apple Silicon that we do on Intel x86_64 but we welcome your help in doing so. Rosetta 2 on Apple Silicon still provides support for Intel x86_64 in /usr/local."

Nvidia is Requiring Laptop Makers To Be More Transparent About RTX 30-series Specs (theverge.com) 15

Nvidia is now requiring, not just encouraging, companies selling laptops with its new RTX 30-series graphics chips to be more transparent about the kind of power people can expect. From a report: Nvidia tells The Verge these companies will have to disclose specific clock speed stats and total graphics power on online product pages -- all of which tells people everything they need to know about a laptop's graphics potential, for better or worse. However, companies won't have to mention that these chips are Max-Q variants because, according to an Nvidia spokesperson, "Max-Q is no longer part of the GPU name." Rather, Max-Q is now solely used to communicate that a laptop with an RTX 30-series graphics chip ships with efficiency features like Whisper Mode 2, Dynamic Boost 2, and Advanced Optimus. Previously, seeing Max-Q branding made it easy to determine a laptop's general performance without having to know its specific clock speeds. It's encouraging to see Nvidia no longer allows companies to hide this vital information from marketing materials. It should go far enough in helping buyers make an educated purchase without having to wait on reviewers and early adopters to report on the specs.

The Empire State Building and Its Related Buildings Are Now Powered By Wind (thehill.com) 192

The iconic Empire State Building that has crowned Midtown Manhattan since the early 1930s is now a game changer in American architecture in a different way: by becoming completely powered with renewable energy. The Hill reports: Announced on Wednesday, Empire State Realty Trust (ESRT) confirmed that it struck a three-year contract with Green Mountain Energy to power its entire commercial real estate portfolio with renewable wind electricity. This reportedly makes ESRT the largest user of green power in U.S. real estate. Green Mountain Energy, based out of Vermont, is a leading sustainable energy provider, offering plans with public and private real estate groups using solar panels and wind turbines as the source of electricity.

ESRT controls more than 10.1 million square feet of real estate, all of which will be powered by renewable energy for the next three years. This switch will spare about 450 million pounds of carbon dioxide emissions from entering the atmosphere. This is roughly the equivalent of every New York State household turning off all of their lights for an entire month. Prior to this partnership, the Empire State Building underwent renovations a decade ago to help convert the building to be more environmentally friendly, resulting in a 40 percent reduction in energy usage prior to the contract with Green Mountain.

A New Lens Technology Is Primed To Jump-Start Phone Cameras (wired.com) 50

An anonymous reader quotes a report from Wired: A new company called Metalenz, which emerges from stealth mode today, is looking to disrupt smartphone cameras with a single, flat lens system that utilizes a technology called optical metasurfaces. A camera built around this new lens tech can produce an image of the same if not better quality as traditional lenses, collect more light for brighter photos, and can even enable new forms of sensing in phones, all while taking up less space.

Instead of using plastic and glass lens elements stacked over an image sensor, Metalenz's design uses a single lens built on a glass wafer that is between 1x1 to 3x3 millimeter in size. Look very closely under a microscope and you'll see nanostructures measuring one-thousandth the width of a human hair. Those nanostructures bend light rays in a way that corrects for many of the shortcomings of single-lens camera systems. The core technology was formed through a decade of research when cofounder and CEO Robert Devlin was working on his PhD at Harvard University with acclaimed physicist and Metalenz cofounder Federico Capasso. The company was spun out of the research group in 2017.

Light passes through these patterned nanostructures, which look like millions of circles with differing diameters at the microscopic level. The resulting image quality is just as sharp as what you'd get from a multilens system, and the nanostructures do the job of reducing or eliminating many of the image-degrading aberrations common to traditional cameras. And the design doesn't just conserve space. Devlin says a Metalenz camera can deliver more light back to the image sensor, allowing for brighter and sharper images than what you'd get with traditional lens elements. Another benefit? The company has formed partnerships with two semiconductor leaders (that can currently produce a million Metalenz "chips" a day), meaning the optics are made in the same foundries that manufacture consumer and industrial devices -- an important step in simplifying the supply chain. Metalenz will go into mass production toward the end of the year. Its first application will be to serve as the lens system of a 3D sensor in a smartphone. (The company did not give the name of the phone maker.)

Robots Are Speeding Up the Most Boring Job In Astronomy (sciencemag.org) 20

sciencehabit writes: The Sloan Digital Sky Survey (SDSS) has, for more than 20 years, pioneered collecting spectra from millions of astronomical objects, from nearby stars to supermassive black holes. But this year, the survey is making a change: Instead of employing a small team of technicians for the daily chore of plugging optical fibers into preprepared plates so that -- when placed in the telescope -- they collect light from exactly the right position in the sky, the SDSS is going robotic. For the project's upcoming fifth set of surveys, plug plates are being replaced by 500 tiny robot arms, each holding fiber tips, that patrol a small area of the telescope's focal plane. They can be reconfigured for a new sky map in 2 minutes. Although such robot spectrographs have been built before, the SDSS is part of a rush to retrofit robots to older telescopes so astronomers can grab spectra from the wealth of interesting objects that will soon be streaming from new imaging surveys.

Remote Tasmanian Island To Be Powered By 'Blowhole' Energy That Harnesses Waves (theguardian.com) 94

An anonymous reader quotes a report from The Guardian: Technology that harnesses wave energy through a "blowhole" is being tested at a remote Tasmanian island in a project backed by federal grants and investors. When the mostly above-water unit is connected in about a month, King Island in Bass Strait will be powered by three renewables -- wave, wind and solar. And there are hopes the project can be expanded across Australia's vast southern coastline.

Wave Swell Energy co-founder Tom Denniss says the pilot will provide crucial data about the system's potential. "It's very much like an artificial blowhole," he said. "There's a big underwater chamber that's open out the front, so the water is forced into the chamber. "It pushes that air back and forth. The movement of air that spins the turbine and produces electricity." Research by the peak scientific body estimates wave energy could contribute up to 11% of the nation's energy by 2050, the equivalent of a city the size of Melbourne. The boat-like structure can generate up to 200kW of power but there are plans for larger 1,000kW models.

Boston Dynamics' Robot Dog Gets an Arm Attachment, Self-Charging Capabilities (arstechnica.com) 51

An anonymous reader quotes a report from Ars Technica: After a year of working with businesses and getting feedback, Boston Dynamics is launching a new Spot revision, a long-awaited arm attachment, and some new features. Now, with the new "Spot Arm" -- a six-degrees-of-freedom gripper that can be mounted to the front of the robot -- Spot can actually do stuff and manipulate the environment around it. Boston Dynamics' latest video shows an arm-equipped Spot opening doors, picking up laundry, dragging around a cinderblock, and flipping switches and valves. Since this is a Boston Dynamics video, there's also a ton of fun footage like three Spots playing jump rope, planting a tree, and drawing the Boston Dynamics logo with a piece of chalk. The arm is not just a siloed device on top of Spot; any arm movement is coordinated with the whole body of the robot, just as a human's arm works. Boston Dynamics pointed to a 2013 video of the (much bigger) BigDog robot heaving a cinderblock across the room. This advanced "lift with your legs, put your back into it" whole-body movement is the core of Boston Dynamics' arm locomotion.

In the palm of the gripper is a 4K color camera, a ToF (Time of Flight) sensor for depth imaging, and LEDs for light. The camera is great to not only see what you're trying to pick up but also as a movable inspection camera that offers a lot more flexibility compared to the stationary face- and back-mounted cameras. The arm weighs 17.6 lbs (8kg) and with a half-meter extension can lift 11 lbs (5kg). The gripper's peak clamp force is 130N. That's far below the average human adult grip strength of 300N and puts Spot in the range of a frail senior citizen, but it's good enough to turn a doorknob. It's especially impressive that in this video, Spot demoed opening a smooth, round doorknob, not an easier-to-open ADA-compliant door handle, which is what most robot/door interactions focus on. It can even make sure the door doesn't hit it in the butt on the way out.

Just like for regular movement, controlling the arm via the tablet uses a user-friendly "supervised autonomy" system. You tell the robot what to grab, and it will figure out how to grab it using all the joints of the arm and legs. There's even a special "door opening" mode, where the user points at the doorknob, enters which side of the door the hinge is on, and Spot will do the rest. There's also an API for the arm control, allowing developers to make their own control interface.
There's also a new version of Spot called "Spot Enterprise," which features the ability to self-charge via an included charging dock, where Spot can park itself on the charging dock when it is low on power. It takes about two hours to fully charge.

Electric Cars Would Save America Huge Amounts of Energy (bloomberg.com) 401

An anonymous reader shares an opinion piece from Bloomberg, written by Liam Denning and Elaine He: Electrifying U.S. vehicles wipes out the equivalent of our entire current power demand. The U.S. consumes a lot of energy; last year, about 100 quadrillion BTUs (equivalent to 17 billion barrels of oil; which, we'll admit, is only marginally less abstract). But only about a third of that is ultimately used in terms of actually lighting lights, turning wheels and so forth. The second law of thermodynamics means, for every unit of thermal energy we actually put to useful work, roughly another two end up wasted as heat. How we don't use energy is just as important to understand as how we use it. Here's a simplified version of a Sankey diagram from the Lawrence Livermore National Laboratory showing the various inputs to the U.S. energy system and where they end up.

Large-scale waste is unavoidable with a thermal energy system, or one where we mostly burn stuff or split atoms (97% of the inputs in 2019). Burning fossil fuels also generates the carbon emissions causing climate change; so wasted energy is a proxy for the damage being done (apart from nuclear power). In contrast, renewables such as wind, solar and hydropower capture energy directly from infinite sources. While a small amount is lost in transmission, the vast majority is used. So here's a thought experiment: What if the entire U.S. light-duty vehicle fleet (currently about 270 million cars and trucks) were electrified by 2030 and we expanded wind and solar generation at a rapid pace, while eliminating coal power, at the same time? The result is that we not only end up with a drop in U.S. carbon emissions of almost 30%, but also a far more efficient system overall.

New Study: A Zero-Emissions America is Now Pretty Cheap (arstechnica.com) 240

"Until recently, it was unclear whether variable renewable energy, nuclear, or fossil fuel with carbon capture and storage would become the main form of generation in a decarbonized electricity system," argues a recently-published analysis titled Carbon-Neutral Pathways for the United States.

"The cost decline of variable renewable energy over the last few years, however, has definitively changed the situation."

Ars Technica reports: In many areas of the United States, installing a wind or solar farm is now cheaper than simply buying fuel for an existing fossil fuel-based generator. And that's dramatically changing the electricity market in the U.S. and requiring a lot of people to update prior predictions. That has motivated a group of researchers to take a new look at the costs and challenges of getting the entire U.S. to carbon neutrality.

By building a model of the energy market for the entire U.S., the researchers explored what it will take to get the country to the point where its energy use has no net emissions in 2050 — and they even looked at a scenario where emissions are negative. They found that, as you'd expect, the costs drop dramatically — to less than 1 percent of the GDP, even before counting the costs avoided by preventing the worst impacts of climate change. And, as an added bonus, we would pay less for our power...

The researchers estimate that the net cost of the transformation will be a total of $145 billion by 2050, which works out to be less than one-half percent of the GDP that year. That figure does include the increased savings from electrical heating and vehicles, which offset some of their costs. But it doesn't include the reduced costs from climate change or lower health care spending due to reduced fossil fuel use. These savings will be substantial, and they will almost certainly go well beyond offsetting the cost. Due to the reduced cost of renewable generation, the authors project that we'll spend less for electricity overall, as well... Part of the reason it is so cheap is because reaching the goal doesn't require replacing viable hardware. All of the things that need to be taken out of service, from coal-fired generators to gas hot-water heaters, have finite lifetimes. The researchers calculate that simply replacing everything with renewables or high-efficiency electric versions will manage the transition in sufficient time...

The scenarios with additional constraints produce some odd results as well. The only scenario in which nuclear power makes economic sense is the one in which land use is limited.

The US Government's Entire 645,000-Vehicle Fleet Will Go All-Electric (msn.com) 216

Jalopnik reports: The United States government operates a fleet of about 645,000 vehicles, from mail delivery trucks to military vehicles and passenger cars. On Monday, President Joe Biden announced that his administration intends to replace them all with American-made, electric alternatives...

In 2015, the government operated 357,610 gasoline vehicles and 3,896 electric ones; in 2019, those numbers grew to 368,807 and 4,475, respectively. That's excluding the tens of thousands of E-85 ["flex fuel"] and diesel-based vehicles on the road, which, together, comprise nearly a third of the 645,047 total. So, yeah, there's certainly a lot of work to do...

The Washington Post reports: The declaration is a boon to the fledgling electric vehicle industry, which has grown exponentially in the past decade but still represents less than 2 percent of automobiles sold in the United States... "It's important as a symbolic thing," said Timothy Lipman, co-director of the Transportation Sustainability Research Center at the University of California at Berkeley. "But I think it also will have a way of helping to jolt the industry forward at a time when it kind of needed that...."

One of the biggest issues: Just three automakers currently manufacture electric vehicles in the United States, and none of those cars meet Biden's criteria of being produced by union workers from at least 50 percent American-made materials. The closest is the Chevrolet Bolt, assembled at a General Motors plant in Lake Orion, Michigan. But most of that car's parts — including the battery, motor and drive unit — are produced overseas. But that could easily change, said Kristin Dziczek, vice president of industry, labor and economics at the nonprofit Center for Automotive Research.

If Biden succeeds in making every car in the federal fleet electric, he would increase the total number of electric vehicles in the United States by more than 50 percent. "One of the big questions for companies is, 'Is the consumer there?' Well, [the government] is a big consumer," Dziczek said. "Now they know there's some solid demand from the government to support their early launches of new vehicles...." With 640,000 nonelectric vehicles, the federal fleet represents the annual output of about three or four automotive plants, Dziczek said. That's not exactly the million jobs Biden promised in his announcement Monday. But it might be sufficient to convince car manufacturers to change their supply chains or shift their production to U.S. facilities.

Cook also said Apple now has an installed base of more than 1 billion iPhones, an increase over the 900 million the company most recently disclosed in 2019."
