Submission + - Electric Vehicles Close To 'Tipping Point' of Mass Adoption (theguardian.com)

An anonymous reader writes: Electric vehicles are close to the “tipping point” of rapid mass adoption thanks to the plummeting cost of batteries, experts say. Global sales rose 43% in 2020, but even faster growth is anticipated when continuing falls in battery prices bring the price of electric cars dipping below that of equivalent petrol and diesel models, even without subsidies. The latest analyses forecast that to happen some time between 2023 and 2025. The tipping point has already been passed in Norway, where tax breaks mean electric cars are cheaper. The market share of battery-powered cars soared to 54% in 2020 in the Nordic country, compared with less than 5% in most European nations. Prof Tim Lenton, at the University of Exeter, said: “There’s been a tipping point in one country, Norway, and that’s thanks to some clever and progressive tax incentives. Then consumers voted with their wallets.”

Data from Lenton’s latest study showed that in 2019, electric vehicles in Norway were 0.3% cheaper and had 48% market share. In the UK, where electric cars were 1.3% more expensive, market share was just 1.6%. Once the line of price parity was crossed, Lenton said, “bang – sales go up. We were really struck by how non-linear the effect seems to be." BloombergNEF’s analysis predicts lithium-ion battery costs will fall to the extent that electric cars will match the price of petrol and diesel cars by 2023, while Lenton suggests 2024-2025. McKinsey’s Global Energy Perspective 2021, published on January 15, forecasts that “electric vehicles are likely to become the most economic choice in the next five years in many parts of the world."

Submission + - Medical study suggests iPhone 12 with MagSafe can deactivate pacemakers (9to5mac.com)

AmiMoJo writes: When Apple revived MagSafe with the iPhone 12 lineup, one question brought up was how these latest devices with more magnets would interact with medical devices like pacemakers. Apple’s official word was that iPhone 12/MagSafe wouldn’t interfere more than previous iPhones. Now one of the first medical studies has been published by the Heart Rhythm Journal that saw a Medtronic pacemaker deactivated by holding an iPhone 12 near it (via MacMagazine). It doesn’t sound like there is concrete evidence that iPhone 12 and MagSafe do pose a greater risk of increased interference but with this study out now, we may see more testing in the medical field to find out for sure.

Of course it’s not just iPhones or smartphones that can create interference issues, it can be any item that contains magnets strong enough create a problem.

Submission + - Superconducting Microprocessors? Turns Out They're Ultra-Efficient (ieee.org)

AmiMoJo writes: Computersuse a staggering amount of energy today. According to one recent estimate, data centers alone consumetwo percent of the world’s electricity, a figure that’s expected to climb to eight percent by the end of the decade. To buck that trend, though, perhaps the microprocessor, at the center of the computer universe, could be streamlined in entirely new ways.

One group of researchers in Japan have taken this idea to the limit, creating a superconductingmicroprocessor—one with zero electrical resistance. The new device, the first of its kind, is described in a study published last month in theIEEE Journal of Solid-State Circuits.

Superconductormicroprocessors could offer a potential solution for more energy efficient computing power—but for the fact that, at present, these designs require ultra-cold temperaturesbelow 10 kelvin (or -263 degrees Celsius). The research group in Japan sought to create a superconductor microprocessor that’s adiabatic, meaning that, in principle, energy is not gained or lost from the system during the computing process.

Submission + - SPAM: NASA is finally ready to test-fire the engines of its SLS megarocket

schwit1 writes:

The space agency plans to test-fire the four main engines of its first SLS heavy-lift booster on Saturday (Jan. 16) at the Stennis Space Center in Mississippi. It's a critical test for NASA and the final step in the agency's "Green Run" series of tests to ensure the SLS rocket is ready for its first launch, Artemis 1, that will send an uncrewed Orion spacecraft around the moon later this year.

The SLS is NASA's go-to rocket to send astronauts to the moon by 2024 as part of its Artemis program. Artemis 1 is the first of what's expected to be a series of missions leading up to Artemis 3, NASA's first crewed moon landing since the Apollo era.

In the upcoming hot-fire engine test, engineers will load the Boeing-built SLS core booster with over 700,000 gallons of cryogenic (that's really cold) propellant into the rocket's fuel tanks and light all four of its RS-25 engines at once. The engines will fire for 485 seconds (a little over 8 minutes) and generate a whopping 1.6 million pounds of thrust throughout the test.

$14.8 BILLION worth of efficiency while SpaceX tested the engines of its rocket, three times, in a row, this afternoon.

Submission + - US Asks Tesla To Recall 158,000 Vehicles For Touchscreen Failures (reuters.com)

An anonymous reader writes: The National Highway Traffic Safety Administration (NHTSA) on Wednesday asked Tesla to recall 158,000 Model S and Model X vehicles over media control unit (MCU) failures that could pose safety risks by leading to touchscreen displays not working. The auto safety agency made the unusual request in a formal letter to Tesla after upgrading a safety probe in November, saying it had tentatively concluded the 2012-2018 Model S and 2016-2018 Model X vehicles “contain a defect related to motor vehicle safety.”

Tesla did not immediately respond to a request for comment but it must respond to NHTSA by Jan. 27. If it does not agree it must provide the agency “with a full explanation of its decision.” It is unusual for the agency to formally demand a recall. Automakers typically voluntarily agree to a recall if sought in discussions by regulators. The agency said it sought the recall after considering “Tesla’s technical briefing presentation ... and evaluated Tesla’s assertions.” NHTSA added that “during our review of the data, Tesla provided confirmation that all units will inevitably fail given the memory device’s finite storage capacity.”
