Waymo has a new peer-reviewed study (PDF) to share that shows how safe its autonomous cars are compared to cars driven by humans. SFist reports: As the Chronicle notes, the study covers the 1.76 million driverless miles that Waymo's cars have registered in San Francisco so far, along with about 5.4 million miles registered elsewhere. It compares data about vehicle crashes of all kinds, and finds that Waymo vehicles were in involved in crashes resulting in injury or property damage far less often than human-driven cars. In fact, the "human benchmark" -- which is what Waymo is using to refer to human averages for various driving foibles -- is 5.55 crashes per 1 million miles. And the Waymo robot benchmark is just 0.6 crashes per 1 million miles. The overall figure for crash rates found Waymo's to be 6.7 times lower (0.41 incidents per 1 million miles) than the rate of humans (2.78 per million). This included data from Phoenix, San Francisco, and Los Angeles.

The report's "Conclusions" section is less than definitive in its findings, noting that the data of police-reported incidents across various jurisdictions may not be consistent or "apples-to-apples." "The benchmark rates themselves... varied considerably between locations and within the same location," the report's authors say. "This raises questions whether the benchmark data sources have comparable reporting thresholds (surveillance bias) or if other factors that were not controlled for in the benchmarks (time of day, mix of driving) is affecting the benchmark rates."

Still, the report, one of several that Alphabet-owned Waymo has commissioned in recent months, is convincingly thorough and academic in its approach, and seems to be great news for the company as it hopes to scale up -- starting with the enormous LA market. Waymo, like Cruise previously, has sought to convince a skeptical public that driverless vehicles are, in fact, safer than humans. And this is another step toward doing so -- even if people are going to be naturally wary of sharing the road with too many robots.

"EVs mandates are coming to Canada whether you like it or not," writes Slashdot reader Major_Disorder, sharing a report from the Canadian Broadcasting Corporation. "Here is what my Canadian brothers and sisters need to know." From the report: New regulations being published this week by Environment Minister Steven Guilbeault will effectively end sales of new passenger vehicles powered only by gasoline or diesel in 2035. Guilbeault said the Electric Vehicle Availability Standard will encourage automakers to make more battery-powered cars and trucks available in Canada. "There's no mistaking it. We are at a tipping point," he said, noting sizable growth in EV sales in Canada and demand that has previously outstripped the available supply.

Automakers will have the next 12 years to phase out combustion engine cars, trucks and SUVs with a requirement to gradually increase the proportion of electric models they offer for sale each year. The electric-vehicle sales mandate regulations will be published later this week. They are setting up a system in which every automaker will have to show that a minimum percentage of vehicles they offer for sale are fully electric or longer-range plug-in hybrids. It will start with 20 per cent in 2026 and rise slightly to 23 per cent in 2027. After that, the share of EVs will begin to increase much faster, so that by 2028, 34 per cent of all vehicles sold will need to be electric -- 43 per cent by 2029 and 60 per cent by 2030. That number keeps rising until it hits 100 per cent in 2035.

Guilbeault said the government is working to revise the national building code to encourage the spread of charging stations. The updated code would ensure that residential buildings constructed after 2025 have the electrical capacity to accommodate the charging stations. [...] The policy will be regulated under the Canadian Environmental Protection Act and will issue credits to automakers for the EVs they sell. Generally, a fully electric model will generate one credit, with plug-in hybrids getting partial or full credit depending on how far they can go on a single charge. Manufacturers that sell more EVs than they need to meet each year's target can either bank those credits to meet their targets in future years, or sell them to companies that didn't sell enough. They can also cover up to 10 per cent of the credits they need each year by investing in public fast-charging stations. Every $20,000 spent on DC fast chargers that are operating before 2027 can earn the equivalent of one credit. Automakers that come up short for their sales requirements will be able to cover the difference by buying credits from others who exceed their targets, or by investing in charging stations. Automakers can start earning some credits toward their 2026 and 2027 targets over the next two years -- a bid by the government to encourage a faster transition.

Southwest Airlines is still paying for its meltdown during the 2022 holidays that stranded millions of travelers -- and the tab is growing. From a report: The U.S. Transportation Department has ordered Southwest to pay a $140 million civil penalty, part of a broader consent order after the airline's operational failures a year ago. That penalty is by far the largest the DOT has ever levied for consumer protection violations, according to a statement from the department. "This is not just about Southwest," Transportation Secretary Pete Buttigieg said in an interview with NPR's Morning Edition on Monday. "This is about the entire industry, sending a signal that you should not be cutting corners -- because if you fail your passengers, we will hold you accountable."

A major winter storm last December caused travel disruptions across the country as airlines canceled thousands of flights. But while other airlines recovered relatively quickly, Southwest fell apart. The airline ultimately canceled 16,900 flights, stranding more than 2 million passengers. In a statement, Southwest described the agreement as "a consumer-friendly settlement." The airline says it has taken steps since last year's disruption to improve its operational resiliency and customer care.

"Unlike automobiles, jumbo jets cannot run on batteries," notes the Washington Post.

So Friday the White unveiled a plan for "subsidizing sustainable aviation fuels" — which could also give the U.S. a leg up in a brand new industry: Senior White House officials said the program would make the airline industry cleaner while bringing prosperity to rural America. But environmental groups and some scientists expressed reservations about the plan, which would award subsidies based on a scientific model that has previously been used to justify incentives for corn-based ethanol. Studies have found the gasoline additive is exacerbating climate change.

The new tax credits, created through President Biden's signature climate law, are meant to spur production of jet fuels that create no more than half the emissions of the petroleum-based product. Each gallon of such fuel qualifies for a tax credit up to $1.75 per gallon. "The concern is they will end up subsidizing fuels that take an enormous amount of land to produce," said Tim Searchinger, a senior research scholar at Princeton University... Administration officials said on a call with reporters Thursday that they are carefully weighing such concerns. Agencies are in the process of updating the scientific model for gauging climate friendliness of jet fuels, they said, and it will be revised to factor in the emissions impact of cropland converted from food to fuel production. Federal agencies plan to complete their revisions by March 1.

"The sustainable aviation fuel industry is a potential 36 billion gallon industry that for all intents and purposes is just getting started," Agriculture Secretary Tom Vilsack said on the call. "This is a big, big deal."

General Motors' Cruise robotaxi unit announced today that it will lay off 900 employees, or 24% of its workforce. The news follows the departure of nine executives amid an ongoing safety investigation following an inccident in which a pedestrian was dragged by one of the company's self-driving cars. CNBC reports: The company had 3,800 employees before Thursday's cuts, which also follow a round of contractor layoffs at Cruise last month. Affected employees will receive paychecks until Feb. 12 and at least an additional eight weeks of pay, plus severance based on tenure. A Cruise representative also told CNBC that the company's goal is now to work on a fully driverless L4 service, as well as relaunching ride-hailing in one city to start. In a statement, a Cruise spokesperson said, "We shared the difficult news that we are reducing our workforce, primarily in commercial operations and related corporate functions. These changes reflect our decision to focus on more deliberate commercialization plans with safety as our north star. We are supporting impacted Cruisers with strong severance and benefits packages and are grateful to the departing employees who played important roles in building Cruise and supporting our mission."

GM added, "GM supports the difficult employment decisions made by Cruise as it reflects their more deliberate path forward, with safety as the north star. We are confident in the team and committed to supporting Cruise as they set the company up for long-term success with a focus on trust, accountability and transparency."

According to Reuters, General Motors' Cruise robotaxi unit dismissed nine executives amid an ongoing safety investigation, which the company confirmed included Chief Operating Officer Gil West. The company conducted a full safety review following an incident in San Francisco where a pedestrian was struck and dragged by one of its cars. GM already halted service nationwide and removed its cars from public roads. Reuters reports: CEO Kyle Vogt and co-founder Dan Kan both resigned in recent weeks and Cruise is preparing for a round of layoffs this month. "Following an initial analysis of the October 2 incident and Cruise's response to it, nine individuals departed Cruise," according to the memo. "We are committed to full transparency and are focused on rebuilding trust and operating with the highest standards when it comes to safety, integrity, and accountability," the memo said. "As a result, we believe that new leadership is necessary to achieve these goals."

The Cruise spokesperson confirmed that among those dismissed was also Chief Legal and Policy Officer Jeff Bleich and Senior Vice President of Government Affairs David Estrada. Cruise's troubles are also a setback for an industry dependent on public trust and the cooperation of regulators. The unit had in recent months touted ambitious plans to expand to more cities, offering fully autonomous taxi rides. The investigation, led by law firm Quinn Emmanuel, is expected to last until January, GM has said. "The personnel decisions made today are a necessary step for Cruise to move forward as it focuses on accountability, trust and transparency," GM said in a statement.

Earlier this year, General Motors announced plans to phase out Apple CarPlay and Android Auto, shifting instead to built-in infotainment systems developed with Google. Now, the company has explained why it made that decision to MotorTrend: Tim Babbitt, GM's head of product for infotainment, gave MT a better explanation at a press event for the new Chevrolet Blazer EV, the flagship vehicle in the no CarPlay or Android Auto strategy. According to him, there's an important factor that didn't make it into the fact sheet: safety. Specifically, he cited driver distraction caused by cell phone usage behind the wheel. According to Babbitt, CarPlay and Android Auto have stability issues that manifest themselves as bad connections, poor rendering, slow responses, and dropped connections. And when CarPlay and Android Auto have issues, drivers pick up their phones again, taking their eyes off the road and totally defeating the purpose of these phone-mirroring programs. Solving those issues can sometimes be beyond the control of the automaker. You can start to see GM's frustration. Babbitt's thesis is that if drivers were to do everything through the vehicle's built-in systems, they'd be less likely to pick up their phones and therefore less distracted and safer behind the wheel. He admits, though, GM hasn't tested this thesis in the lab or real world yet but believes it has potential, if customers go for it.

The issues Babbitt cited with CarPlay and Android Auto seem like they'd be mostly linked to using those programs wirelessly, and while he says that's true, just plugging the phone into a USB data port doesn't solve all the problems. Babbitt says even when using a physical connection, Android phones are prone to compatibility issues between the vehicle and all the various phone manufacturers running Android. iPhones, meanwhile, suffer from backwards compatibility issues that cause older iPhone models to have trouble running CarPlay consistently. He points to J.D. Power data that shows issues with CarPlay and Android Auto are common owner complaints, and that customers tend to blame the automaker rather than the phone manufacturer or phone software. In that way, eliminating CarPlay and Android Auto potentially relieves GM of a key customer complaint dragging down their perceived quality scores. After MotorTrend's story was published, GM issued the following statement: "We wanted to reach out to clarify that comments about GM's position on phone projection were misrepresented and to reinforce our valued partnerships with Apple and Google and each company's commitment to driver safety. GM's embedded infotainment strategy is driven by the benefits of having a system that allows for greater integration with the larger GM ecosystem and vehicles."

As racetracks close and old aircraft engines get harder to find, the crowd-pleasing spectacles are endangered. From a report: Magdatude is a 1946 Chevy pickup modified with a jet engine. It wasn't put there for speed. On a rainy September night, the truck rumbled onto the infield of the Rockford Speedway in Illinois, stopping with its business end about 10 feet from a junk minibus. The engine whined to life and shot a blast of fire from its afterburner, engulfing the bus until it was reduced to a charred metal skeleton. "There's nothing left of that thing!" the announcer shouted. "Holy cow!"

It was a textbook jet car meltdown, once a common spectacle at racetracks and drag strips. The fiery craft has become endangered as venues close, spare parts grow scarce and practitioners dwindle. "I think realistically there's going to be a few people that keep it alive," said Josh Baumgartner, Magdatude's owner. "We're hoping to be among them."

A former Navy mechanic named Doug Rose helped to popularize meltdowns after he created a dragster using a jet engine from a scrapyard. According to his widow, Jeanne, he conducted his first fire show around 1968 with a car he named the Green Mamba. Over the years, he honed his craft until he could torch a half-dozen vehicles at once. "Doug's objective was to please the people," she said.

"The machines in the facility waft air towards a water-based solvent," reports the Times of London, "which carbon dioxide in the air dissolves into. An electrical current then separates those compounds from the solvent, creating a pure stream of CO2."

More details from Sky News: The UK's first-ever direct air capture plant has been turned on to remove CO2 from the atmosphere and turn it into jet fuel. The machine, developed by Mission Zero Technologies in partnership with the University of Sheffield, will run on solar power to recover 50 tonnes of CO2 from the air per year and turn it into Sustainable Aviation Fuel (SAF)...

Aviation accounts for about 2% of the world's emissions and Ihab Ahmed, research associate from the University of Sheffield, said the fuel has the capacity to massively reduce the impact of aviation on the environment — and is an important step towards the government's ambitious target to increase the use of SAF to at least 10% by 2030.
America opened its first carbon-capture facility in November in a warehouse in California. While the carbon isn't converted into sustainable air fuel, it can capture a maximum of 1,000 tons of carbon dioxide per year/

An anonymous reader quotes a report from The Verge: Stellantis struck a deal with California-based EV battery swapping company Ample to power a fleet of shared Fiat 500e vehicles in Spain. But the company says the deal could eventually expand to include personally owned EVs in Europe and the US as well. By becoming one of the first Western automakers to embrace battery swapping technology, Stellantis is betting that EV charging infrastructure in Europe and the US will remain a barrier to adoption in the near future, necessitating other solutions. Battery swapping could theoretically help EV owners power up and get moving without having to wait for long stretches at a charging station.

Stellantis will work with Ample to launch a battery swapping system for a fleet of Fiat 500e vehicles as part of a car-sharing service through its Free2move subsidiary. The service will first appear in Madrid in 2024, where the Fiat 500e is already available. (The tiny EV won't come to North America until next year.) Ample has four stations already in operation in the city and plans to build an additional nine stations in the months to come. Stellantis will need to install modular batteries in the Fiat 500e in order to be compatible with Ample's swapping system. The process works by driving the vehicle into a station, where it gets raised slightly. Ample's robot arms remove the spent battery from underneath the vehicle, replace it with a fully charged one, and then lower the vehicle. The company says the whole process can take as little as five minutes. "Our system knows how many batteries are in the Fiat 500e, knows how to extract each one of those modules, and put them back in the same arrangement," Khaled Hassounah, CEO of Ample, said in a briefing with reporters.

Starting with a small fleet of shared vehicles in one city will help Stellantis see how well Ample's system works and whether it can be scaled to new markets and to include privately owned vehicles. If the company does decide to expand its partnership with Ample, the Fiat 500e will likely be the first vehicle to support the technology, said Ricardo Stamatti, senior VP for charging and energy at Stellantis. Customers who buy cars that are compatible with Ample's swapping system would then just subscribe to a battery, opening up a possible new line of revenue for Stellantis. "We believe that this is actually an infrastructure play that can and will scale," Stamatti added.

An anonymous reader quotes a report from Motherboard: A high-speed train from the greater Los Angeles area to Las Vegas took a big step closer to reality thanks to a $3 billion federal grant from the Department of Transportation and Joe Biden's signature infrastructure law. The proposed line will be built by Brightline West, a private company owned by Fortress Investment Group. It promises to use all-electric high-speed trains that can travel up to 180 mph, which will half the travel time from Los Angeles to Las Vegas without even taking into account the terrible traffic during peak travel times. The one catch is the LA station will be in Rancho Cucamonga, about 45 miles from Union Station (it is, however, connected via Metrolink trains). The Las Vegas station is more centrally located close to the airport. [...]

Brightline West may be the flashiest rail project in the U.S. at the moment, but it's hardly alone. The U.S. is experiencing a modest but real resurgence in rail expansion thanks to the Bipartisan Infrastructure Law. In addition to Brightline West, a Raleigh-to-Richmond rail corridor received a $1 billion grant to be fit for reliable passenger service, a major boon to a region with good bones for passenger service and high demand that has become neglected and dominated by freight rail. North Carolina is experiencing record passenger rail ridership thanks to more service between Raleigh and Charlotte, two metro areas that have experienced massive population booms in recent decades and desperately need better rail service. The Bipartisan Infrastructure Act is also providing tens of billions of dollars in funding to upgrade Northeast Corridor infrastructure between Washington D.C. and Boston, the nation's busiest rail route. The other California High Speed rail route, the one that a state authority has been trying to build for decades that will only go from Bakersfield to Merced, also received $3 billion in federal funding.

Press2ToContinue shares a report from Politico: Congress at the urging of the Biden administration agreed in 2021 to spend $7.5 billion to build tens of thousands of electric vehicle chargers across the country, aiming to appease anxious drivers while tackling climate change. Two years later, the program has yet to install a single charger. States and the charger industry blame the delays mostly on the labyrinth of new contracting and performance requirements they have to navigate to receive federal funds. While federal officials have authorized more than $2 billion of the funds to be sent to states, fewer than half of states have even started to take bids from contractors to build the chargers -- let alone begin construction. [...]

The goal is a reliable and standardized network in every corner of the nation, said Gabe Klein, executive director of the Joint Office of Energy and Transportation, which leads the federal government's efforts on EV charging. "You have to go slow to go fast," Klein said in an interview. "These are things that take a little bit of time, but boy, when you're done, it's going to completely change the game." [...] Aatish Patel, president of charger manufacturer XCharge North America, is worried the delays in installing chargers are imperiling efforts to drive up EV adoption. "As an EV driver, a charger being installed in two years isn't really going to help me out now," Patel said. "We're in dire need of chargers here."

The Biden administration is expecting a deluge of chargers funded by the law to break ground in early 2024. A senior administration official granted anonymity to speak on the specifics of the rollout said the pace is to be expected, given that the goal is to create a "convenient, affordable, reliable, made-in-America equitable network." "Anybody can throw a charger in the ground -- that's not that hard, it doesn't take that long," the official said. "Building a network is different." The administration insists it is doing all it can to speed up the process, including by streamlining federal permitting for EV chargers and providing technical assistance to states and companies through the Joint Office. It expects the U.S. to hit Biden's 500,000 charger target four years early, in 2026, the official said.

An anonymous reader quotes a report from Ars Technica: US Senator Edward Markey (D-Mass.) is one of the more technologically engaged of our elected lawmakers. And like many technologically engaged Ars Technica readers, he does not like what he sees in terms of automakers' approach to data privacy. On Friday, Sen. Markey wrote to 14 car companies with a variety of questions about data privacy policies, urging them to do better. As Ars reported in September, the Mozilla Foundation published a scathing report on the subject of data privacy and automakers. The problems were widespread -- most automakers collect too much personal data and are too eager to sell or share it with third parties, the foundation found.

Markey noted (PDF) the Mozilla Foundation report in his letters, which were sent to BMW, Ford, General Motors, Honda, Hyundai, Kia, Mazda, Mercedes-Benz, Nissan, Stellantis, Subaru, Tesla, Toyota, and Volkswagen. The senator is concerned about the large amounts of data that modern cars can collect, including the troubling potential to use biometric data (like the rate a driver blinks and breathes, as well as their pulse) to infer mood or mental health. Sen. Markey is also worried about automakers' use of Bluetooth, which he said has expanded "their surveillance to include information that has nothing to do with a vehicle's operation, such as data from smartphones that are wirelessly connected to the vehicle." "These practices are unacceptable," Markey wrote. "Although certain data collection and sharing practices may have real benefits, consumers should not be subject to a massive data collection apparatus, with any disclosures hidden in pages-long privacy policies filled with legalese. Cars should not -- and cannot -- become yet another venue where privacy takes a backseat."

The 14 automakers have until December 21 to answer Markey's questions.

Today is the 20th anniversary of its last flight of the supersonic Concorde aircraft. It was faster than the speed of sound, travelling at speeds of 1,350 mph (2,170 km/h).

Long-time Slashdot reader schwit1 shared an article from the Telegraph: As the space race raged and dominated headlines, the U.S. and the Soviet Union were equally competitive about being the first post-war superpower to create a commercial jetliner that could travel faster than the speed of sound." Both started work on secret projects, at the same time that Britain and France — who were less hell-bent on imprinting their superiority on geopolitics, but blessed with many of the world's finest engineering minds — were in pursuit of the same goal.

It has been known for decades that the three-horse race wasn't run entirely fairly. While the Americans, with their colossal and largely pointless Boeing 2707, never got close to getting airborne (they scrapped the project in 1971), the Soviet-built Tupolev Tu-144 won the race in 1968. When it did, though, its design similarities to Concorde appeared to confirm suspicions that the blueprints might have been leaked by espionage. In the late 1990s, it was revealed that an aeronautical engineer codenamed Agent Ace was one such spy. Recruited in 1967, he allegedly handed over some 90,000 pages of detailed technical specifications on new aircraft — including Concorde, the Super VC-10 and Lockheed L-1011 — to the KGB, the foreign intelligence and domestic security agency of the Soviet Union.
The identity of Agent Ace is revealed in Concorde: The Race for Supersonic, a new two-part documentary by the UK public broadcasting station Channel 4.

The Telegraph adds: With the rich benefit of hindsight, John Britton isn't entirely surprised there was a Soviet mole in the factory. It was a long time ago, 1965, but something — or someone — at Filton Aerodrome seemed fishy. "We had dozens, maybe hundreds of people working on the project, and we didn't have enough permanent staff so we took on contractors, all sorts of characters," Britton says. At the time he was a 19-year-old apprentice engineer, working for British Aeroplane Company (BAC) in the design office for a supersonic, passenger-carrying aircraft. An aircraft that would, ideally, fly before the Soviet Union's competing effort did.

"There was one chap working there... He used to stay behind, he'd do a lot of overtime in the drawing library, taking prints off the microfilms of designs..." Britton, who is now 76, initially assumed the man — he thinks his name was George — was merely conscientious and needed copies for his work. He can titter at the memory now. "It was only afterwards, when the Soviet aircraft came out and it looked remarkably like Concorde, when we thought... 'Ah'."

Consumer Reports awarded a "recommended" rating to Tesla's Modey Y this year, "with owners reporting fewer issues with its suspension, in-car electronics and general build quality than in previous years". Tesla's Model 3 also earned a "recommended" rating.

"Tesla's Model 3 and Model Y are now the sweet spot in the automotive industry when it comes to building electric cars," says Jake Fisher, the senior director of auto testing for Consumer Reports. "While Tesla is still a relatively new car company, it has more experience producing EVs than any other automaker."

But how about the larger universe of all automakers? Electric vehicle owners continue to report far more problems with their vehicles than owners of conventional cars or hybrids, according to Consumer Reports' newly released annual car reliability survey. The survey reveals that, on average, EVs from the past three model years had 79 percent more problems than conventional cars...

"Most electric cars today are being manufactured by either legacy automakers that are new to EV technology, or by companies like Rivian that are new to making cars," says Jake Fisher, senior director of auto testing at Consumer Reports. "It's not surprising that they're having growing pains and need some time to work out the bugs." Fisher says some of the most common problems EV owners report are issues with electric drive motors, charging, and EV batteries...

This year's survey data show that hybrids continue to be among the most reliable vehicle type: Hybrids have 26 percent fewer problems than conventional models, even though they have both a conventional powertrain and an electric motor and therefore more potential problem spots than conventional cars. "It might not seem that long ago, but Toyota launched the Prius hybrid about 25 years ago," Elek says. "Automakers have been making hybrids long enough that they've gotten really good at it. Plus, many hybrids are also made by manufacturers that tend to produce reliable vehicles overall, such as Toyota, Hyundai, and Kia." Hybrids also are not typically loaded with high-tech features like multiple customizable displays that can be problem-prone, which is why Fisher says they are great options for drivers who are more interested in getting ideal fuel mileage than they are in bells and whistles. "These vehicles are not necessarily a tour de force of technology, so there's just less that can go wrong with them," he says.

Plug-in hybrid electric vehicles (PHEVs), which have both a battery for short-range electric driving and an internal combustion engine for long-range driving, are the least reliable category — 146 percent more problems than conventional cars. "PHEVs are sort of like an EV and a conventional car rolled into one, so by their nature they have more things that can go wrong with them," Fisher says.
There are exceptions, notes the auto testing director. Toyota's RAV4 Prime plug-in hybrid "is one of the most reliable models in our survey this year. Similarly, the Ford F-150 hybrid has transmission and other issues that buck the trend of strong hybrid reliability."

Tesla's new Cybertruck is more than their first new model since 2020, reports the Verge: Tesla announced a new "Powershare" vehicle-to-load charging capability, only available on the new Cybertruck. The feature will allow Cybertruck owners to power their camping equipment, power tools, or even their entire home during a blackout, just by using their electric truck as a mobile generator.

The truck also features a 240-volt outlet in the rear bed that can be used to charge other EVs. An image on Tesla's website shows the Cybertruck charging a Model Y.

The Cybertruck can put out as much as 11.5kW, which is more than the Ford F-150 Lightning's 9.6kW of onboard power or the GMC Sierra Denali EV's 10.2kW. Tesla has been talking about manufacturing vehicles with bidirectional charging capabilities for several years now, first teasing the feature at its Battery Day event in 2020. Since then, many of its competitors have adopted the feature for their EVs, including Ford, GM, Hyundai, Kia, and others...

In essence, it treats high-capacity lithium-ion batteries not only as tools to power EVs but also as backup storage cells to charge other electric devices, an entire home, or even to send power to the electrical grid for possible energy savings... Customers who want to take advantage of the Powershare feature in their homes will need a Tesla Powerwall (of course) and a Wall Connector for the most seamless connection.
Tesla held a launch event for the vehicle on Thursday, and demand appears to be high. Jalopnik reports Tesla is now offering people who'd reserved a Cybertruck a $1,000 discount if they'll instead order another Tesla model.

The first wireless charging public roadway in the United States has been installed in Detroit's Corktown neighborhood. Electrek reports: Wireless charging provider Electreon provided inductive-charging copper coils that were installed below the road's surface. The coils will charge EVs equipped with Electreon receivers as they drive over the road. The road's charging segments transfer electricity wirelessly through a magnetic field, which is then transferred as energy to the vehicle's battery, charging it. Detroit's wireless charging roadway is a pilot that will test and aim to perfect the wireless charging technology in a real-world environment. Researchers are using a Ford E-Transit equipped with an Electreon receiver.

The plan is to open it up to the public in the next few years. MDOT and Electreon have entered a five-year commitment to develop and pilot the electric road system on Michigan roads. The pilot is on a quarter-mile stretch on 14th Street between Marantette and Dalzelle Streets in Detroit's historic Corktown. It runs alongside the Newlab at Michigan Central Building, home to more than 60 tech and mobility startups, where the wireless charging tech will be further tested and developed beginning in early 2024. In 2024, MDOT will begin seeking bids to rebuild part of Michigan Avenue (US-12) and will install additional inductive charging.

Rolls-Royce announced plans to sell its electric flight division to focus on its core businesses. AeroTime reports: The sale of the electric business division could bring in between 1 and 1.5 billion pounds to Rolls-Royce coffers. In this regard, Rolls-Royce is betting on sustainable aviation fuel (SAF) as the main driver of decarbonization for the aviation industry. All of Rolls-Royce's in-production engine types will be able to run on 100% SAF. The engine maker is optimistic about its new UltraFan, an improved efficiency engine technology which was successfully tested earlier in 2023. Rolls-Royce expects UltraFan engines to power both widebody and narrowbody aircraft in the future. Rolls-Royce also noted that it sees opportunities in the executive aviation segment and is targeting 8-9% growth in Pearl engine deliveries.

Rolls-Royce is currently in the middle of a restructuring program to turn itself around and boost profitability. The pandemic had a strong impact on the engine maker, as the company's service revenues depend heavily on the number of hours engines are in use. [CEO Tufan Erginbilgic] said he expected the group to increase its profits to the 2.5-2.8 billion pound range, up from the 0.65 billion pound profit it reported in 2022. The civilian aerospace division is expected to make the largest contribution to this turnaround and reach profit margins of 15 to 17% by 2027 (compared to the group's goal of 13-15%), up from the meagre 2.5% it reported for the last fiscal year. New submitter HammerOn1024 comments: "They are SELLING not shutting down, so keep the harping to a dull roar please."

"Two articles from Electrek and InsideEVs describe Hyundai and Kia's new 'Uni Wheel' drive system that could revolutionize EV design," writes longtime Slashdot reader Uncle_Meataxe. From a report: Described by its makers as a "paradigm-shifting vehicle drive system," the Uni Wheel moves the main drive system components to the vacant space within an EVs wheel hubs. The approach utilizes a planetary gear configuration consisting of a sun gear in the center, four pinion gears on each side, and a ring gear surrounding everything. Traditional ICE vehicles utilize CV joints, but by moving them closer to the wheels requires a short drive train length and as a result, a decrease in efficiency and durability -- especially over bumpy terrain. Hyundai and Kia's Uni Wheel system on the other hand, can transmit power with almost zero changes to efficiency, regardless of wheel movement. "Advantages include more platform space and more room within an EV's interior," adds Uncle_Meataxe. "When this system may be integrated into an actual EV remains unclear, but Kia and Hyundai have already registered eight patents related to the technology." You can learn more about the new drive system via an instructional video on YouTube.

An anonymous reader quotes a report from The Guardian: Air pollution from traffic can cause a significant rise in blood pressure that can last up to 24 hours, according to a study via the University of Washington. The spike is comparable to the effect of a high-sodium diet and can contribute to cardiovascular problems. Long-term exposure to vehicle exhaust has been widely linked with respiratory problems such as asthma, especially in children. "Traffic air pollution increases blood pressure within an hour of being in traffic and it stays elevated a day later," said author of the study Joel Kaufman, a physician and professor of environmental and occupational health sciences at the University of Washington.

Sixteen healthy people between the ages of 22 and 45 underwent three separate drives as passengers through Seattle rush hour. Two of those drives were "unfiltered," meaning the road air was allowed to enter the car, as is the case for many drivers on the road today. On the third drive, a Hepa (high efficiency particulate absorbing) filter was installed in the car, with participants unaware which drive had filtration. The researchers measured the blood pressure of the passengers before, during and after the two-hour drive. Breathing unfiltered air resulted in blood pressure increase of more than 4.5mm Hg (millimeters of mercury) compared to filtered air. Most of the pollution came from tailpipe exhaust or the fossil fuel combustion, as well as brake and tire wear. The filters were most effective in reducing ultrafine particles (86% decrease), black carbon, which is mostly from diesel (86%), and PM2.5 (60%) while gasses like carbon dioxide and nitrogen oxide were unaffected. "The clue here is that these tiniest particles are probably what's responsible for blood pressure difference," Kaufman said.

"If you live in an area that has heavy traffic-related air pollution, you want to keep your windows closed and have air filtration capability in your home."
