At least four people have died across the region.

Elon Musk’s The Boring Company has submitted a proposal to construct a 6.2-mile underground transit system in Miami, Insider can reveal.

The North Miami Beach Loop would ferry Tesla vehicles between seven stations along State Road 826, between the Golden Glades Transit Center and Sunny Isles Beach at Newport Pier, according to the proposal, seen by Insider.

The Boring Company estimated that the loop would initially be able to carry more than 7,500 passengers per hour, and could be scaled to carry more than 15,000 per hour.

Tesla has announced that it has produced 1 million of its next-generation 4,680 battery cell at its pilot factory in California.

The announcement comes as Tesla is expected to start deliveries of its new Model Y equipped with its 4,680 cell and structural battery pack.

In 2020, Tesla unveiled its new 4,680 battery cell, a new tabless cylindrical cell in a much bigger format that the company claimed produces six times the power and five times the energy capacity while significantly reducing the cost.

The US National Transportation Safety Board (NTSB) says it is investigating the February 16 crash of a Joby Aviation air taxi prototype in Jolon, California.

The experimental air taxi was being piloted remotely when it went down during a flight at the company’s test base on Wednesday. According to a preliminary report by the FAA, no injuries have been reported.

Michelin has been working with General Motors to develop airless tires that will be sold on a next-generation Chevrolet Bolt electric car, expected to go on sale in the next few years, a Michelin executive said. It could mark the decline of over 130 years of tire tradition but also the end of one of the most annoying aspects of car ownership: keeping air in the tires.

“We want to bring the next generation of the Chevrolet Bolt with airless tires,” Alexis Garcin, president of Michelin North America said in an interview with CNN Business, “and it’s going to happen now in the next three to five years.”

Today’s rechargeable batteries are a wonder, but far from perfect. Eventually, they all wear out, begetting expensive replacements and recycling.

“But what if batteries were indestructible?” asks William Chueh, an associate professor of materials science and engineering at Stanford University and senior author of a new paper detailing a first-of-its-kind analytical approach to building better batteries that could help speed that day. The study appears in the journal Nature Materials.

Chueh, lead author Haitao “Dean” Deng, Ph.D. ‘21, and collaborators at Lawrence Berkeley National Laboratory, MIT and other research institutions used artificial intelligence to analyze new kinds of atomic-scale microscopic images to understand exactly why batteries wear out. Eventually, they say, the revelations could lead to batteries that last much longer than today’s. Specifically, they looked at a particular type of lithium-ion batteries based on so-called LFP materials, which could lead to mass-market electric vehicles because it does not use chemicals with constrained supply chains.

GreenCore EV Services has a goal of building and operating a network of over 10,000 solar EV charging plazas throughout the United States by the end of the decade. The company’s charging plazas will serve both consumer and commercial vehicles.

To help usher in this goal, GreenCore announced that it has selected B&D Industries to provide labor and prefabrication services to build out the company’s network of solar-powered EV charging plazas.

The U.S. used to be a global leader in lithium production, but now has fallen way behind. Several domestic projects are in the works, but will it be enough?

Lithium-sulfur batteries have three times the potential charge capacity of lithium-ion batteries, which are found in everything from smartphones to electric cars. Their inherent instability, however, have so far made them unsuitable for commercial applications, with lithium-sulfur batteries undergoing a 78 per cent change in size every charging cycle.

Overcoming this issue would not only radically improve the performance of battery-powered devices, it would also address some of the environment concerns that come with lithium-ion batteries, such as the sourcing and disposal of rare raw materials.
