Thanksgiving Weekend Sports Guide: Your roadmap to NFL matchups, other games, times, oddsTire companies have begun making EV tires . There’s nothing really special about them. Despite all their claims, most are no different from a tire that’s on a gas powered vehicle. They’re working to change that it seems as the race is on to develop the perfect, all around EV tire. Wired reports that tire manufacturers such as Michelin and Continental are developing the next generation of EV tires. It’s not an easy task as these tires will have to deliver on multiple fronts. One of the challenges is rolling resistance. Less rolling resistance means more range, so manufacturers are experimenting with different compounds to get less rolling resistance. Manufacturers are experimenting with nanomaterials in their tires, such as nanocarbon and nanosilica , to improve performance, traction, and durability. There is also research into bio-based alternative compounds such as guayule and dandelion rubber . You can reduce rolling resistance by reducing tread depth, but this also means the tire won’t last so long and produces increased noise. Continental, however, thinks it has the answer. “We have developed special soft rubber compounds that allow us to reduce rolling resistance and noise at the same time without sacrificing mileage,” says Thomas Wanka, principal technology development engineer at Continental. Another issue is tire particulates. EVs do not produce emissions, however they do produce particulates from tires and brake dust. Since electric powertrains are so heavy, EVs burn through tires 20 percent faster than a internal combustion engine. However, it’s tricky directly comparing the pollution from particles shed by tires to exhaust fumes from an internal combustion engine. Even though 1.5 kilograms of rubber particles still sounds bad, there is a significant difference between particle sizes. The major culprit for public health is NOx , which causes smaller particulates in the “PM2.5” category (meaning the particles are 2.5 microns in diameter). For tires, only 1 percent of particulates are below PM10 (10 microns), and 0.2 percent PM2.5 or below. Most PM2.5 pollution in urban areas still comes from vehicle exhaust NOx. Unfortunately, there is scant research into the health effects of tire particulates. One of the few comprehensive studies was completed more than a decade ago, in 2012. “At that time, it was not decided that it was the priority subject,” says Gary Guthrie, senior vice president at Michelin. “The priority subject was more understanding the fate of particles in water and how they degrade.” Another innovation corporate scientists are exploring is biodegradable tires made from sustainable materials like recycled tires. Gunnlaugur Erlendsson, CEO of a startup tire company called Enso says that while this would be a win for the environment, a biodegradable tire wouldn’t have great durability. “A tire that biodegrades on the vehicle would not be good for durability. However, it would be beneficial if the tire particles that shed during driving could biodegrade in the environment, preventing them from accumulating in our air, land, and oceans,” he said. Tire particulate is pretty terrible, and not just for humans. Research scientists in the Pacific Northwest called tire particulates the “DDT of our generation” for its affect on salmon and other wild fish. If memory serves, DDT ended up not being so good for human life either.

Paul Keating has emerged as a significant winner from the sale of Boost Mobile, with the former prime minister set to pocket at least $40 million from the telco tie-up. Telstra on Monday announced it would acquire Boost Mobile in a deal understood to be worth just under $140 million in cash, a move that will enable Telstra to spruik low-cost prepaid plans amid an ongoing cost-of-living crunch. Former prime minister Paul Keating was the initial funder of Boost Mobile. Credit: Louie Douvis Keating holds a 29 per cent stake in Boost Mobile and remains one of the company’s largest shareholders. He was the sole investor when he co-founded the business in 2000 with entrepreneur Peter Adderton, who retains a 32 per cent stake. Other shareholders include skateboarder Peter Hill and his brother Stephen Hill, as well as former Boost Mobile chief executive Paul O’Neile. The acquisition, expected to be completed this month, will see Boost Mobile employees integrated into Telstra and no changes for Boost’s thousands of prepaid customers. The companies had been partnered for 13 years, with Telstra responsible for most of the operational parts of Boost’s business, including network access and customer service, while Boost was responsible for branding and marketing. “Boost Mobile has been a fantastic partner of Telstra, this acquisition cements just how much we value the Boost brand,” Telstra executive Brad Whitcomb said. Boost Mobile chairman Peter Adderton owns about a third of the company he founded with Keating in 2000. “We know Boost branded products are a fantastic option for those seeking more affordable mobile connectivity, and we are committed to providing that choice in the market.” Boost Mobile chairman Peter Adderton, who owned about a third of the company he founded in 2000, said the acquisition was a natural evolution for his brand. “I am excited to see how the brand will continue to grow under Telstra’s ownership,” he said. “The team at Boost are the best in the business and I wish them all well on the next part of Boost Mobile’s journey.” More to come The Business Briefing newsletter delivers major stories, exclusive coverage and expert opinion.

By Jonathan Stempel (Reuters) -A federal judge on Friday rejected the U.S. Securities and Exchange Commission's request to sanction Elon Musk after he failed to appear for court-ordered testimony for the regulator's probe into his $44 billion takeover of Twitter. U.S. District Judge Jacqueline Scott Corley in San Francisco said sanctions over Musk's Sept. 10 absence were unnecessary, after the world's richest person testified on Oct. 3 and agreed to pay the SEC's $2,923 of travel costs. "Because the present circumstances forestall any occasion for meaningful relief that the court could grant, the SEC's request is moot," Corley wrote. The SEC had sought a declaration that Musk violated a May 31 court order to provide testimony. It said having only to repay travel costs would not deter many other people from ignoring court orders, "much less someone of Musk's extraordinary means." Musk said he complied with the order by testifying on Oct. 3. He is worth $321.7 billion according to Forbes magazine. The SEC did not immediately respond to a request for comment after business hours. Lawyers for Musk did not immediately respond to similar requests. Musk, whose businesses include electric car maker Tesla and rocket company SpaceX and who is the world's richest person, went to Florida's Cape Canaveral on Sept. 10 to oversee the launch of SpaceX's Polaris Dawn mission. The SEC is investigating whether Musk violated securities laws in early 2022 by waiting at least 10 days too long to disclose he had begun accumulating Twitter stock. Critics and some investors have said this let him buy shares cheaply before he eventually disclosed a 9.2% Twitter stake, and shortly thereafter offered to buy the whole company. In July, Musk said he misunderstood SEC disclosure rules and that "all indications" suggested he made a "mistake." The SEC also sued Musk in 2018 over his Twitter posts about taking Tesla private. He settled that lawsuit by paying a $20 million fine, agreeing to let Tesla lawyers review some posts in advance and stepping down as Tesla's chairman. The case is SEC v Musk, U.S. District Court, Northern District of California, No. 23-mc-80253.
