Tesla’s engine with no rare earth elements

[Blueprint]( Tesla is using a [permanent magnet motor without rare earth elements](. It was suitably vague when asked about the precise materials it employs, but the company has indicated that its new engine will have a permanent magnet, but it won't use rare earth elements. Permanent magnets made of neodymium have long been the standard for EV engines, but over the last ten years, research has focused on other possible materials that might take its place. But before you focus your attention on that, take a look at [this video](. It gives you a tour of the five largest semi-trucks on the road. They’re pretty gargantuan. Good morning.

MUST READ [Tesla will use a magnetic engine to stop using rare earth elements.]( [Tesla will use a magnetic engine to stop using rare earth elements.]( Tesla CEO Elon Musk has revealed that the company is to develop a [permanent magnet electric vehicle engine]( that doesn’t use any rare earth elements. This is significant because of supply difficulties, and the fact that China accounts for the vast majority of global production. So rare earth elements are a source of friction in the EV supply chain. EV motors employ rare earth elements rather than batteries. The most popular is neodymium, which is used to create strong magnets for electric motors, hard drives, and speakers. Neodymium magnets frequently contain the additions of dysprosium and terbium. But not all electric car motors use rare earth elements; Tesla uses them in its DC permanent magnet motors but not in its AC induction motors. → Tesla's vehicles were initially powered by AC induction motors, which did not require rare earth elements. The company has now announced that by improving the efficiency of the drivetrain during the last five years, it has been able to cut the use of rare earth elements by 25 percent in its new Model 3 drive units.

The sailing ship Ironton ran into another ship and sank in 1894. Cutting-edge oceanographic technology was used to find the shipwreck of the Ironton in Lake Huron. The team used NOAA's Great Lakes Environmental Research Lab's RV Storm, a 50-foot (15-meter) research vessel equipped with multibeam sonar, to map the lakebed.
