"Long before the harrowing Alaska Airlines blowout on January 5, there were concerns within Boeing about the way the aerospace giant was building its planes," reports the Wall Street Journal.

There's been issues with various models — like "misdrilled holes, loose rudder bolts, and this month's MAX 9 door-plug blowout" — but many can be traced back to the outsourcing Boeing and other aerospace companies adopted more than 20 years ago where key pieces are built elsewhere and then assembled at Boeing. And the Journal reports that the door-plug was built at a factory that Boeing owned until 2005, now run by Spirit AeroSystems, that "has been plagued by production problems and quality lapses since Boeing ceded so much responsibility for its work... " Spirit is the sole supplier of the fuselages used in many Boeing jets, including the Alaska plane that made the emergency landing. It is heavily dependent on Boeing for revenue, and the two companies have battled for years over costs and quality issues. The earlier MAX grounding and Covid-19 pandemic sapped Spirit's finances, and the company slashed thousands of jobs, leaving it short-handed when demand bounced back. Some Spirit employees said production problems were common and internal complaints about quality were ignored. In a given month, at a production rate of two fuselages a day, there are 10 million holes that need to be filled with some combination of bolts, fasteners and rivets. "We have planes all over the world that have issues that nobody has found because of the pressure Spirit has put on employees to get the job done so fast," said Cornell Beard, president of the International Association of Machinists and Aerospace Workers chapter representing workers at Spirit's Wichita factory... Alaska Airlines and United Airlines say they have found loose hardware on other MAX 9 jets they have checked, suggesting that problems go beyond one plane...

The company, which had 15,900 workers in four U.S. factories at the end of 2019, laid off thousands of people in Wichita at the height of the pandemic. When it needed to ramp back up, not only did Spirit have fewer people on site, the company had lost years of expertise. There were fewer experienced mechanics, but also fewer experts who could inspect the quality of their work. [Spirit CEO Pat Shanahan ] said the quick production ramp-up and the earlier MAX grounding left the company short of experienced workers. "When you have disruption, you have instability," he said...

For more than a decade, Spirit and Boeing battled over costs, quality and the pace of production. Boeing's demands for lower prices left Spirit strapped for cash as managers panicked over meeting increasingly demanding deadlines. Boeing routinely had employees on the ground in Wichita and conducted audits of the supplier. The result, some current and former employees say: a factory where workers rush to meet unrealistic quotas and where pointing out problems is discouraged if not punished. Increasingly, they say, planes have been leaving Wichita with so-called escapements, or undetected defects. "It is known at Spirit that if you make too much noise and cause too much trouble, you will be moved," said Joshua Dean, a former Spirit quality auditor who says he was fired after flagging misdrilled holes in fuselages. "It doesn't mean you completely disregard stuff, but they don't want you to find everything and write it up." His account is included in a shareholder lawsuit filed in December against Spirit that alleges the company failed to disclose costly defects.

A Spirit spokesman said the company strongly disagrees with the assertions and intends to defend against the suit...

After being laid off during the pandemic shutdown, Dean returned to Spirit in May 2021. By then, he said, the company had lost many of its most experienced mechanics and auditors. Spirit already was under more intense scrutiny from Boeing. The jet maker placed Spirit on a so-called probation, in which the company more closely scrutinized the supplier's work. To get off probation, Spirit needed to reduce the number of defects on the line. At one point, Dean said, the company threw a pizza party for employees to celebrate a drop in the number of defects reported. Chatter at the party turned to how everyone knew that the defect numbers were down only because people were reporting fewer problems.

On the Spirit factory floor, some machinists building planes say their concerns about quality rarely get conveyed to more senior managers, and that quality inspectors fear retaliation if they point out too many problems. Union representatives complained to leaders last fall that the company removed inspectors from line jobs and replaced them with contract workers after they flagged multiple defects.
Two key quotes from the article:

• "As some problems on both the 787 and 737 were traced back to Spirit, Boeing executives said in 2023 that the plane maker would be ratcheting up oversight of the supplier it once owned."

• New FAA chief Mike Whitaker said "Whatever's happened over the previous years — because this has been going on for years — has not worked." When it comes to what caused last week's in-flight incident, "All indications are it's manufacturing."

After a 737 Max door panel blew out over Portland, Oregon, last week, the Federal Aviation Administration ordered the temporary grounding of Boeing 737 Max 9 aircraft until emergency inspections were performed. "Alaska and United Airlines, which operate most of the Max 9s in use in the United States, said on Monday that they discovered loose hardware on the panel when conducting preliminary inspections on their planes," reported the New York Times. Now, U.S. aviation regulators say they may strip Boeing of its right to conduct some of its aircraft inspections. The Financial Times reports: Mike Whitaker, FAA administrator, said the agency was "exploring" its options for using an independent third-party to oversee inspections of Boeing's aircraft and its quality controls. "It is time to re-examine the delegation of authority and assess any associated safety risks," he said. "The grounding of the 737-9 and the multiple production-related issues identified in recent years [at Boeing] require us to look at every option to reduce risk."

The regulator also said it plans to immediately increase its oversight of Boeing's production. The FAA opened an investigation on Thursday into whether the planes Boeing builds match the specifications it has laid out. The FAA said it will audit the 737 Max 9 production line and its suppliers "to evaluate Boeing's compliance with its approved quality procedures," with further audits conducted as necessary.

Washington Senator Maria Cantwell sent a letter (PDF) yesterday to the FAA questioning the agency's role in inspecting aircraft manufactured by Boeing. Cantwell said she asked a year ago for an audit of certain areas related to Boeing's production, and the regulator told her it was unnecessary. "Recent accidents and incidents -- including the expelled door plug on Alaska Airlines flight 1282 -- call into question Boeing's quality control," she said. "In short, it appears that FAA's oversight processes have not been effective in ensuring that Boeing produces aeroplanes that are in condition for safe operation."

An anonymous reader quotes a report from The Guardian: Joe Biden's administration has unveiled $623 million in funding to boost the number of electric vehicle charging points in the U.S., amid concerns that the transition to zero-carbon transportation isn't keeping pace with goals to tackle the climate crisis. The funding will be distributed in grants for dozens of programs across 22 states, such as EV chargers for apartment blocks in New Jersey, rapid chargers in Oregon and hydrogen fuel chargers for freight trucks in Texas. In all, it's expected the money, drawn from the bipartisan infrastructure law, will add 7,500 chargers to the US total.

There are about 170,000 electric vehicle chargers in the U.S., a huge leap from a network that was barely visible prior to Biden taking office, and the White House has set a goal for 500,000 chargers to help support the shift away from gasoline and diesel cars. "The U.S. is taking the lead globally on electric vehicles," said Ali Zaidi, a climate adviser to Biden who said the US is on a trajectory to "meet and exceed" the administration's charger goal. "We will continue to see this buildout over the coming years and decades until we've achieved a fully net zero transportation sector," he added. On Thursday, the House approved legislation to undo a Biden administration rule meant to facilitate the proliferation of EV charging stations. "S. J. Res. 38 from Sen. Marco Rubio (R-Fla.), would scrap a Federal Highway Administration waiver from domestic sourcing requirements for EV chargers funded by the 2021 bipartisan infrastructure law. It already passed the Senate 50-48," reports Politico.

"A waiver undercuts domestic investments and risks empowering foreign nations," said Rep. Sam Graves (R-Mo.), chair of the Transportation and Infrastructure Committee, during House debate Thursday. "If the administration is going to continue to push for a massive transition to EVs, it should ensure and comply with Buy America requirements." The White House promised to veto it and said it would backfire, saying it was so poorly worded it would actually result in fewer new American-made charging stations.

An anonymous reader quotes a report from TechCrunch: Polestar CEO Thomas Ingenlath couldn't be happier with the integration of Google built-in, the branded product that embeds Google apps and services directly into the company's EVs. But don't expect the EV maker to drop Android Auto or Apple CarPlay as a result. On the sidelines of CES 2024, Ingenlath committed to sticking with Android Auto and Apple CarPlay, the middleware that allows drivers to project their smartphone onto the car's infotainment display. He went a step further and questioned automakers that have. GM, for instance, decided not to make the new 2024 Chevy Blazer EV compatible with Android Auto or Apple CarPlay.

"It's still too important for our customers to have the choice," Ingenlath said during an interview at CES 2024. He later added that, in his view, removing the option isn't the right way of treating customers. "Our priority is very clear; We have a really fantastic system together with Google," he said. While Ingenlath admitted that adding that Google Built-in provides the best experience, he asked "why would we try to dogmatically educate our customers?" Polestar has been a champion of Google built-in. However, it's willingness to keep Android Auto and Apple CarPlay is notable because it illustrates the complexity of appeasing customers even if it might overshadow the native technology in the vehicle. "Ingenlath seems convinced that as Google built-in improves and continues to add apps and services, consumers will give up Android Auto or Apple CarPlay on there own," adds TechCrunch. "And the updates do keep coming."

"At CES 2024, for instance, Polestar announced that the Chrome browser would start rolling out to Polestar 2 in beta, allowing drivers to surf the internet via the central vehicle display while parked. Ingenlath hinted of more improvements in the future, including more precise navigation in Google Maps that drills down to the specific lane as well as customized features designed for Polestar customers."

quonset writes: Hertz rental has announced it's selling off one third of its 20,000 electric vehicle fleet and replacing them with gas powered vehicles. The reason? It's costing them too much to repair damaged EVs and their depreciation is hurting the bottom line.

"[C]ollision and damage repairs on an EV can often run about twice that associated with a comparable combustion engine vehicle," Hertz CEO Stephen Scherr said in a recent analyst call. And EV price declines in the new car market have pushed down the resale value of Hertz's used EV rental cars.

UnknowingFool writes: Following the incident on Alaska Airlines 1282 on Friday where a door plug blew off mid-flight, the FAA ordered all Boeing 737 Max 9 airplanes to be grounded and the door plugs to be inspected. Both United Airlines and Alaska Airlines have now reported finding loose parts on their planes with United specifically listing "bolts" whereas Alaska only referred to "hardware." Both airlines have repaired the situation and put the planes back into service. It remains to be answered why the parts were loose and what further issues could arise.

In just a few weeks, Waymo will begin testing its driverless passenger vehicles on the highways in Phoenix, Arizona. The company will start by shuttling employees, and if all goes well, it will expand its operations to include regular customers. TechCrunch reports: Bringing its autonomous cars to the highway is just the latest in a series of big steps for Waymo, especially in the Phoenix area. In December, the company started offering curbside drop-off and pickup at the Phoenix airport. Just a few months before that, Waymo made its autonomous vehicles available in the Uber app.

Starting in the second quarter of 2024, Volkswagen drivers will be able to install OpenAI's ChatGPT in their vehicles. The Verge reports: The chatbot will be available across VW's lineup, including in Tiguan, Passat, and Golf as well as the automaker's ID family of electric vehicles. The feature will come to Europe first and is being considered for customers in the US, though plans have yet to be finalized. VW is using ChatGPT to augment its IDA in-car voice assistant to enable more naturalistic communication between car and driver. Vehicle owners can use the new super-powered voice assistant to control basic functions, like heating and air conditioning, or to answer "general knowledge questions."

If you're scratching your head, wondering why you would possibly need ChatGPT in your car, VW says future functions may help prove its worth. "Enriching conversations, clearing up questions, interacting in intuitive language, receiving vehicle-specific information, and much more -- purely hands-free," the company says. VW promises it won't force you to create a new account or install any apps. The chatbot can be activated by using the wake words "Hello IDA" or pressing a button on the steering wheel. And OpenAI isn't getting access to your driving stats, either. VW says questions and answers are "deleted immediately to ensure the highest possible level of data protection."

VW says it is able to integrate OpenAI's chatbot into its cars thanks to Cerence, a third-party software company that makes "automative grade" ChatGPT integrations. The company's Cerence Chat Pro software will enhance VW's voice assistant so it can "provide relevant responses to nearly every query imaginable."

An anonymous reader shares a report: Among the harrowing details of the blown-off fuselage panel that triggered a sudden decompression event on Alaska Airlines Flight 1282, one revelation seemed to defy the laws of physics: one of the mobile phones that had been sucked out of the Boeing 737 Max 9 jet's cabin remained in functioning condition after a 16,000-foot tumble. A new-generation Apple iPhone landed intact, unlocked and with hours of battery life remaining on a Portland, Oregon roadside, according to a post on X by a user calling himself Seanathan Bates, who said he discovered the device. The screen showed an email from Alaska Airlines about a baggage claim for the flight, based on Bates' photos.

The phone was in airplane mode, Bates said in a TikTok video. "It was still pretty clean, no scratches on it, sitting under a bush and it didn't have a screenlock on it," he said. The National Transportation Safety Board confirmed at a briefing on Sunday that one phone was found on the side of a road and another in a yard. The people have handed in both of the devices, NTSB Chair Jennifer Homendy told reporters.

As General Motors prepares to roll out electric versions of its Buicks, "hundreds of Buick dealerships nationwide" are "turning their backs on the storied brand," reports the Boston Globe.

"The move to electric Buicks is one reason so many dealers are giving up their Buick franchises, according to auto industry watchers." They say that smaller, low-volume Buick dealers either can't or won't make the big investments needed to begin selling EVs, especially as sales growth in the sector has cooled and unsold electrics are piling up on dealer lots. "I think there are dealers who are just not confident in the electric vehicle transition and they don't want to have to commit to the investment," said Karl Brauer, executive analyst at online car retailer iSeeCars.com...

Buick has announced its intention to migrate to an all-electric line of cars by the end of the decade. The brand's first EV is set to go on sale this year. But getting ready to sell EVs is a costly proposition. Dealers must purchase new equipment to service the cars and must pay for worker retraining. GM estimates that the upfront cost to dealers will range between $200,000 and $400,000. "If you're in a market where you're not selling a lot of Buicks, investing a lot to sell electric Buicks may not make a good business case," said Mark Schirmer, spokesperson for Cox Automotive, an Atlanta-based automotive marketing company.
While 854,000 Buicks were sold in 1980, just 103,000 were sold in 2022 — down from 207,000 in 2019, according to the article. So in 2022 GM bought out 44 percent of its dealerships (which they say accounted for just 20% of all U.S. Buick sales), with the majority of them still selling other GM brands like Chevrolet and GMC.

But the article also includes some perspective from Robert O'Koniewski, executive vice president of the Massachusetts State Automobile Dealers Association. "The only reason GM has kept the Buick alive is that it's popular in China." That's Buick's biggest market by far, thanks to a 50-50 joint venture it launched in 1997 with government-owned SAIC Motor, China's biggest carmaker. The partnership sold 653,000 Chinese Buicks in 2022.

But that's a big decline from the 926,000 sold in 2020. Brauer said that Chinese consumers are pulling away from the US brand in favor of Chinese companies like BYD, which passed Tesla in the fourth quarter of 2023 to become the world's largest maker of electric vehicles.

Today America's Federal Aviation Administration "ordered the temporary grounding of Boeing 737 Max 9 aircraft," reports CNN, identifying the aircraft as "the model involved in an Alaska Airlines emergency landing in Oregon on Friday after a section of the plane apparently blew out in midflight." A passenger's video posted to social media shows a side section of the fuselage, where a window would have been, missing — exposing passengers to the outside air. The video, which appears to have been taken from several rows behind the incident, shows oxygen masks deployed throughout the airplane, and least two people sitting near and just behind the missing section...

The plane "landed safely back at Portland International Airport with 171 guests and six crew members," the airline said... According to FlightAware, the flight was airborne for about 20 minutes.
"There was a really loud bang toward the rear of the plane and a whoosh noise," one passenger told a local news station — and then "all of the masks dropped."

Long-time Slashdot reader ArchieBunker shares more details from the BBC: Diego Murillo said the gap was "as wide as a refrigerator".

Fellow passenger Elizabeth Lee added: "Part of the plane was missing and the wind was just extremely loud. but everyone was in their seats and had their belt on."

Jessica Montoia described the flight as a "trip from hell" adding a phone was taken out of a man's hand by the wind.
CNN covers the federal response: The FAA said the planes must be parked until emergency inspections are performed, which will "take around four to eight hours per aircraft."

"The FAA is requiring immediate inspections of certain Boeing 737 MAX 9 planes before they can return to flight," FAA Administrator Mike Whitaker said Saturday in a statement. "Safety will continue to drive our decision-making as we assist the (National Transportation Safety Board's) investigation into Alaska Airlines Flight 1282." The order impacts 171 Boeing 737 Max 9 jets, the agency approximates....

Boeing said the company supported the FAA's grounding decision. "Safety is our top priority and we deeply regret the impact this event has had on our customers and their passengers," Boeing said in a statement

More than 4 million electric vehicles are now on America's roads. And Friday the U.S. Energy announced that more than a third of them (1.4 million) were sold within the last year.

That's 50% more than were sold in the previous year — and about the same number sold in the entire five years between 2016 and 2021. But the energy secretary's statement also touts the current administrations efforts at "building out a reliable and interoperable nationwide EV charging network — an undertaking never before seen in the United States." Today, the U.S. has close to 170,000 public EV chargers — a 75% increase since the president took office with nearly 900 new chargers coming online per week.

These developments are part of an inevitable shift toward a thriving electric transportation sector — a shift that American automakers and battery manufacturers are already carrying forward.

The White House has convened a last-minute meeting to discuss a private lunar mission, Peregrine Mission One, after the Navajo Nation requested a delay due to cultural concerns over the transport of human ashes for burial on the moon. "The moon holds a sacred place in Navajo cosmology," said Navajo Nation President Buu Nygren in a statement. "The suggestion of transforming it into a resting place for human remains is deeply disturbing and unacceptable to our people and many other tribal nations."

If successful, the commercial mission scheduled to launch Monday "will be the first time an American-made spacecraft has landed on the lunar surface since the end of the Apollo program in 1972," notes CNN. Longtime Slashdot reader garyisabusyguy shares the report: The private companies providing these lunar burial services, Celestis and Elysium Space, are just two of several paying customers hitching a ride to the moon on Pittsburgh-based Astrobotic Technology's Peregrine lunar lander. The uncrewed spacecraft is expected to lift off on the inaugural flight of the United Launch Alliance's Vulcan Centaur rocket from Florida's Cape Canaveral Space Force Station. Celestis' payload, called Tranquility Flight, includes 66 "memorial capsules" containing "cremated remains and DNA," which will remain on the lunar surface "as a permanent tribute to the intrepid souls who never stopped reaching for the stars," according to the company's website.

"We are aware of the concerns expressed by Mr. Nygren, but do not find them substantive," Celestis CEO Charles Chafer told CNN. "We reject the assertion that our memorial spaceflight mission desecrates the moon," Chafer said. "Just as permanent memorials for deceased are present all over planet Earth and not considered desecration, our memorial on the moon is handled with care and reverence, is a permanent monument that does not intentionally eject flight capsules on the moon. It is a touching and fitting celebration for our participants -- the exact opposite of desecration, it is a celebration." Elysium Space has not responded to CNN's request for a comment, but the company's website describes its "Lunar Memorial" as delivering "a symbolic portion of remains to the surface of the Moon, helping to create the quintessential commemoration." "I've been disappointed that this conversation came up so late in the game," John Thornton, Astrobotic Technology CEO, said. "I would have liked to have had this conversation a long time ago. We announced the first payload manifest of this nature to our mission back in 2015. A second in 2020. We really are trying to do the right thing and I hope we can find a good path forward with Navajo Nation." [...]

Friday's meeting convened by the White House is scheduled to feature representatives from NASA, the FAA, the US Department of Transportation, and the Department of Commerce. But Navajo Nation officials have little hope that they will be able to stop Monday's launch. "Based off of what we're seeing, and NASA are already having their pre-launch briefing, it doesn't look like they have any intention of stopping the launch or removing the remains," Ahasteen said.

All new cars and vans bought in the UK must be zero emission by 2035, according to the latest legal mandate updated this week. From a report: The date for all new petrol and diesel cars to be banned was originally set for 2030. However, in September, Prime Minister Rishi Sunak pushed this date back to 2035. The government says this is giving consumers more time to make the switch and deal with the UK's charging infrastructure.

The transition will still be challenging. Eighty percent of new cars and 70 percent of new vans sold in Great Britain must be zero emission by 2030, increasing to 100 percent by 2035. While the government points to statistics indicating a 41 percent increase in zero-emission vehicles registered for the first time -- note, the vast majority of newly registered vehicles still remain conventionally powered -- charging infrastructure is an altogether different story. The government boasts of more than 50,000 public charge points, an increase of 44 percent year on year, but not all chargers are born equal. According to research from RAC, a local roadside assistance business, the government has failed to meet its target of having six or more rapid or ultra-rapid electric vehicle chargers at every motorway service area in England.

According to NBC, law enforcement in California can't ticket driverless cars for traffic violations, thanks to a legal loophole requiring an actual driver in the car. NBC Bay Area reports: An internal memo from San Francisco Police Chief Bill Scott, obtained by the NBC Bay Area Investigative Unit, instructs officers that "no citation for a moving violation can be issued if the [autonomous vehicle] is being operated in a driverless mode." Scott added, "Technology evolves rapidly and, at times, faster than legislation or regulations can adapt to the changes."

While autonomous vehicles in California have received parking citations, the state's transportation laws appear to leave driverless vehicles immune from receiving any type of traffic ticket stemming from moving violations. "I think it sends a message that it's not a level playing field, that fairness is not the priority," said Michael Stephenson, the founder and senior attorney of Bay Area Bicycle Law, a law firm that specializes in representing cyclists in accident cases.

Stephenson said that driverless vehicles don't exactly fit into the state's current legal framework and that California needs new laws to appropriately govern the evolving technology. "We're perhaps trying to shove a square peg into a round hole," he said. "We are very much in the Wild West when it comes to driverless cars." The report notes that other states have rewritten traffic laws to allow ticketing of driverless cars. "Texas, which rivals California as another popular testing ground for autonomous vehicles, changed its transportation laws in 2017 to adapt to the emerging technology," reports NBC. "According to the Texas Transportation Code, the owner of a driverless car is 'considered the operator' and can be cited for breaking traffic laws 'regardless of whether the person is physically present in the vehicle.'"

"Arizona, another busy site for autonomous vehicles, took similar steps," adds NBC. "In revising its traffic laws, Arizona declared the owner of an autonomous vehicle 'may be issued a traffic citation or other applicable penalty if the vehicle fails to comply with traffic or motor vehicle laws.'"

Climate change is already beginning to reshape global agriculture. India, the world's most populous country, looks particularly vulnerable: not just because of extreme weather, but because of government price controls. Fixing the problem is becoming more urgent, both for India and the world -- because India is a big food exporter, too. But politics makes that very difficult. From a report: In early December, India banned overseas shipments of onions until March in an effort to tame domestic prices. That is on top of export restrictions on rice, wheat and sugar already imposed over the past 18 months. And since India is the world's largest rice exporter, second-largest sugar and onion exporter, and a significant wheat producer, the bans are wreaking havoc globally. Thai rice prices had risen 14% and Vietnam rice prices had risen 22% from July levels by October, according to the International Food Policy Research Institute. Malaysia and the Philippines introduced their own measures to damp rising prices after India's curbs on rice exports in July.

Climate change will almost certainly pose a major problem for India's food supply. India's Ministry of Agriculture and Farmers Welfare recently estimated that, in the absence of adaptation measures, rain-fed rice yields could fall 20% by 2050. But domestic agricultural policies are almost as big a problem. At present, the government sets price floors for two dozen crops, guarantees purchases of certain agricultural products, and provides subsidies to farmers for fertilizers, electricity and transportation. All that might seem positive for food security, but on net it probably hampers investment and food supply growth. Price floors mean that supply might sometimes exceed final buyers' willingness to pay during slow times, leading to wastage. And restrictions on exports artificially depress domestic prices when global demand is hot. The government's own investigations have found that Agriculture Produce Marketing Committee laws, which regulate the trade of farmers' produce by providing licenses to buyers, commission agents and private markets, lead to cartelization and reduced competition.

Tesla topped Norway's car sales for a third straight year in 2023, extending its lead over rivals despite an ongoing conflict between the U.S. electric vehicle maker and the Nordic region's powerful labour unions. From a report: Almost five out of six new cars sold in Norway last year were powered by battery only, with Tesla's share of the overall market rising to 20.0% from 12.2%, registration data showed on Tuesday. Electric vehicles accounted for 82.4% of new vehicles sold in 2023, up from 79.3% in 2022, the Norwegian Road Federation (OFV) said. Seeking to become the first nation to end the sale of petrol and diesel cars by 2025, oil-producing Norway exempts fully electric vehicles from many taxes imposed on internal combustion engine rivals, although some levies were introduced in 2023.

"Digital twin technology is one of the most significant disruptors of global manufacturing seen this century," argues Motor Trend, "and the automobile industry is embracing it in a big way." Roughly three-quarters of auto manufacturers are using digital twins as part of their vehicle development process, evolving not only how they design and develop new cars but also the way they monitor them, fix them, and even build them...

Nvidia, best known for its consumer graphics cards, also has a digital twin solution, called Omniverse, which manufacturers such as Mercedes-Benz are using to design their manufacturing processes. "Their factory planners now have every single element in the factory that they can then put in that virtual digital twin first, lay it all out, and then operate it," Danny Shapiro, VP of automotive at Nvidia said. At that point, those planners can run the entire manufacturing process virtually, ensuring every conveyor feeds the next step in the process, identifying and addressing factory floor headaches long before production begins...

Software developers can run their solutions within digital twins. That includes the code at the lowest level, basic stuff that controls ignition timing within the engine for example, all the way up to the highest level, like touchscreens responding to user inputs. "We're not just simulating the operation outside the car, but the user experience," Nvidia's Shapiro said. "We can simulate and basically run the real software that would be running in that car and display it on the screens." By bringing all these systems together virtually, developers can find and solve issues earlier, preventing costly development delays or, worse yet, buggy releases...

Using unique identifiers, manufacturers can effectively create internal digital copies of vehicles that have been produced. Those copies can be used for ongoing tests and verifications, helping to anticipate things like required maintenance or susceptibility to part failures. By using telematics, in-car services that remotely communicate a car's status back to the manufacturer in real-time, these digital twins can be updated to match the real thing. "By monitoring tire health, tire grip, vehicle weight distribution, and other critical parameters, engineers can anticipate potential problems and schedule maintenance proactively, reducing downtime and extending the vehicle's lifespan," Tactile Mobility's Tzur said.

"Electric cars are already upending America," argues a new article in the Atlantic, citing booming sales and new models that are "finally starting to push us into the post-gas age." Americans are on track to buy a record 1.44 million of them in 2023, according to a forecast by BloombergNEF, about the same number sold from 2016 to 2021 total. "This was the year that EVs went from experiments, or technological demonstrations, and became mature vehicles," Gil Tal, the director of the Electric Vehicle Research Center at UC Davis, told me.... Nearly 40 new EVs have debuted since the start of 2022, and they are far more advanced than their ancestors. For $40,000, the Hyundai Ioniq 6, released this year, can get you 360 miles on a single charge; in 2018, for only a slightly lower cost, a Nissan Leaf couldn't go half that distance....

All of these EVs are genuinely great for the planet, spewing zero carbon from their tailpipes, but that's only a small part of what makes them different. In the EV age, cars are no longer just cars. They are computers... The million-plus new EVs on the road are ushering in a fundamental, maybe existential, change in how to even think about cars — no longer as machines, but as gadgets that plug in and charge like all the others in our life. The wonderful things about computers are coming to cars, and so are the terrible ones: apps that crash. Subscription hell. Cyberattacks... If cars are gadgets now, then carmakers are also now tech companies. An industry that has spent a century perfecting the internal combustion engine must now manufacture lithium-ion batteries and write the code to govern them. Imagine if a dentist had to pivot from filling cavities to performing open-heart surgery, and that's roughly what's going on here.

"The transition to EVs is completely changing everything," Loren McDonald, an EV consultant, told me. "It's changing the people that automotive companies have to hire and their skills. It's changing their suppliers, their factories, how they assemble and build them. And lots of automakers are struggling with that...." Job cuts are already happening, and more may come — even after the massive autoworker strike this year that largely hinged on electrification. Such a big financial investment is needed to electrify the car industry that from July to September, Ford lost $60,000 for every EV it sold. Or peel back one more onion layer to car dealerships: Tesla, Rivian, and other EV companies are selling directly to consumers, cutting them out. EVs also require little service compared with gas vehicles, a reality that has upset many dealers, who could lose their biggest source of profit.

None of this is the future. It is happening right now.

"Since the 1960s engineers around the world have been fiddling with a novel type of jet called a rotating detonation engine (RDE), but it has never got beyond the experimental stage," reports the Economist.

"That could be about to change." GE Aerospace, one of the world's biggest producers of jet engines, recently announced it was developing a working version. Earlier this year America's Defence Advanced Research Projects Agency awarded a $29m contract to Raytheon, part of RTX, another big aerospace group, to develop an RDE called Gambit.

Both engines would be used to propel missiles, overcoming the range and speed limitations of current propulsion systems, including rockets and existing types of jet engines. However, if the companies are successful in getting them to work, RDEs might have a much broader role in aviation — including the possibility of helping revive supersonic air travel.

In a nutshell, an RDE "replaces fire with a controlled explosion", explains Kareem Ahmed, an expert in advanced aerospace engines at the University of Central Florida. In technical terms, this is because a jet engine relies on the combustion of oxygen and fuel, which is a subsonic reaction that scientists call deflagration. Detonation, by comparison, is a high-energy explosion that takes place at supersonic speeds. As a result it is a more powerful and potentially a more efficient way of producing thrust, the force that drives an aircraft forward...

By modifying an aircraft's fuselage and wings, engineers believe they can reduce the boom's impact on the ground below. Such work will help to determine whether or not future supersonic passenger planes will, like Concorde, be restricted to flying beyond the speed of sound only over oceans.
