Earlier in the day, news broke that R-R had backed out of the Boom project. “We’ve completed our contract with Boom and delivered various engineering studies for their Overture supersonic program,” the UK engine manufacturer says. “After careful consideration, Rolls-Royce has determined that the commercial aviation supersonic market is not currently a priority for us and, therefore, will not pursue further work on the program at this time. It has been a pleasure to work with the Boom team and we wish them every success in the future.”

Boom, with offices in Denver, has been developing a supersonic aircraft called Overture that it says will carry up to 80 passengers and cruise at Mach 1.7. It initially intended for Overture to have two engines, but recently changed to a four-engined design. The company has been targeting first flight of Overture in 2026 and first delivery in 2029. “Overture remains on track to carry passengers in 2029, and we are looking forward to making our engine announcement later this year,” Boom says.

The company also said it’s issued a software update to improve the ability to predict what other vehicles will do, including in conditions similar to the crash.

There’s some candid discussions about the technology of electric cars – but also some surprisingly personal insights. Musk also reveals he’s been thinking about electric cars since high school, as “the way cars should be, if you could just solve range… People will look back on the internal combustion car era as a strange time. Quaint.” And then he remembers the moment in 1995 when he put his graduate studies at Stanford “on hold” to pursue a business career, reassuring Stanford professor William Nix that “I will probably fail” and predicting an eventual return to Stanford. Nix had responded that he did not think Musk would fail.

It turns out that 27 years later, now-emeritus professor William Nix heard the interview, and typed up a fond letter to Elon Musk at SpaceX’s headquarters in Texas. Nix complimented Musk on the interview, noting Musk’s remarks on the challenges in using silicon for the anodes of electric batteries. “About 10 years ago we at Stanford did research on the very issues you described. Indeed, it almost seemed like you had read all the papers.”

Musk’s hour-long interview with the group was followed by two more hour-long interviews, and since then the group has been sharing short excerpts that give candid glimpses of Musk’s thinking. (The overwhelming focus is solving full self-driving,” Musk says in one clip. “That’s essential. That’s really the difference between Tesla being worth a lot of money and being worth basically zero.”)

Baidu’s Apollo Go is already the world’s biggest robotaxi company, with operations already live in all tier-one Chinese cities using the same 5th-gen car, with backup drivers on board. The company recently revealed its 6th-gen design, its first ground-up fully autonomous car for mass production. The Apollo RT6 will cost just RMB 250,000 (US$37,000) to manufacture, says Baidu, and its optional, removable steering wheel and generous, configurable cabin space will make it one of the first proper mobility pod-type services when it hits the streets commercially in 2023.

The new version of CarPlay could be a huge emerging revenue engine for Apple. First, if a user loves the iPhone’s CarPlay interface, then they’re less likely to switch to an Android phone. That’s a strategic priority for Apple, which generates the majority of its revenue through hardware sales. Second, while the company doesn’t yet charge a fee to automakers or suppliers, it could sell services for vehicles the same way it distributes iPhone software. In June, Apple revealed that it has explored features that integrate commerce into the car’s cockpit. One new feature announced this summer would allow CarPlay users to navigate to a gas pump and pay for the fuel from the dashboard of the car, according to Reuters. Apple already generates tens of billions from the App Store, and stands to boost that if it ever decides to charge for services in cars…

We contacted all three of Detroit’s giants for why they continue to include AM radios when some European makes have phased them out, but the answer establishes itself across those very same lines. AM radio has fallen out of favor in Europe, with Radio Info reporting in 2015 that stations were shutting down en masse from France to the Netherlands and Russia. The frequency has largely been superseded by the DAB format, which is a more advanced form of radio broadcasting with better audio quality and choice of stations. AM radio stations and their listeners are all but gone in Europe, so European carmakers may not need to include technology that many of its customers can’t use.

In the U.S., on the other hand, radio remains a must for car buyers, with 89 percent of responders in a 2021 survey stating radio should be standard in new cars. That makes radio even more important to U.S. car buyers than USB ports, which only 84 percent said were necessary. AM audiences were in rapid decline as of a 2017 report by Inside Radio, but not to enough a degree for American carmakers to leave AM radios out of their products. It’s not hard to figure out why AM’s holding on here, either: AM signals travel further than FM broadcasts do and are cheaper to transmit, allowing them to cater to audiences in sparsely populated areas. Audio quality can’t compare, but that’s secondary to having anything to listen to at all in some parts of the continental United States.

The final stage of testing for TPS’s system is to prove its durability, but Singleton expects this won’t be a problem. “The technology uses all solid-state, high-voltage switches — these are switches that are used in applications where they’re run for millions and millions of shots. If you just did an analysis of the parts, you would say no problem, right? The testing that still needs to be done is, once you’ve put it into a package where it’s going to go to altitude and extreme heat, extreme cold, you just have to do some design validation and tweaking,” he said. […]

As for when we might see the first cars fitted with plasma ignition on the road, Singleton was optimistic. “We are currently in discussions with a couple of Tier 1s and OEMs that are interested in acquiring the technology or working with us to take this to market. The most aggressive timeline that one of those companies has told us is that they could get it to market in 18 months from the start of a deal. That’s aggressive. And typically it takes longer in automotive to do testing, but if they say they can do it, this is their world, not mine. So 18 months, I would say, from the start of a partnership,” Singleton said. Why develop a new internal combustion engine technology when we’re going all in on electric vehicles? Here’s what Singleton told Ars: “[W]e do think that the future is going to be EVs. But the question is, what do we do while we’re ramping up? And I think if you look at the data, it’s pretty compelling that the best thing you can do is to start getting CO2 emissions down now. So that’s really where we see this fitting in is if you put this technology to market immediately. That’s what our data shows is that there’s immediate, meaningful CO2 reductions.”

Ars also notes that “it’s going to be many years before countries like the US stop selling new internal combustion-powered vehicles and longer still until they’re no longer allowed on our roads.”

Waymo describes the team-up as a “deep integration” of each company’s products, including a jointly developed “product roadmap” to outline how autonomous trucks will get deployed on Uber’s network once they are commercial ready. Until then, Waymo says it will use Uber Freight with its own test fleet to better understand how driverless trucks will receive and accept delivery orders. But the partnership goes beyond just beta testing each other’s technology. Waymo said it will reserve “billions of miles of its goods-only capacity for the Uber Freight network” in a capacity commitment meant to underscore the seriousness of this partnership. The report notes that Alphabet’s Waymo sued Uber in early 2017 over allegations of trade secret theft and patent infringement. The two sides reached a settlement agreement about a year later. “Uber later admitted that it misappropriated some of Waymo’s tech and vowed to license it for future use,” adds The Verge.

The best-case scenarios from these new models “rarely happen” in the real world, he says, but his team still hopes to reduce fuel consumption of all vehicles on the road during the trial — not just the driverless cars — by as much as 10 percent. “If you take just the overall cost of the traffic system in any country, and you reduce that by even 5 percent we are talking about billions of dollars,” he says. The researchers have shared their findings in a paper via arXiv.org.
