source：KFGO(Reuters) – As tensions mount between China and the United States, automakers in the West are trying to reduce their reliance on a key driver of the electric vehicle revolution – the magnets made with rare earth metals that power electric engines.Here’s how EVs are powered, and how some automakers are adapting.What’s the difference?Permanent magnet motors – using rare earths such as neodymium and dysprosium – naturally have magnetic force. These are at the heart of many electric motors, powering the rotor of the drivetrain.Motors without permanent magnets, such as induction motors, ...

source:YahooThe many-gigabit internet speed records of a decade ago now seem downright inadequate. Motherboard reports that scientists at Japan's National institute of Information and Communications Technology (NICT) have smashed the internet transfer record by shuffling data at 319Tbps. For context, that's almost twice as fast as the 179Tbps a team of British and Japanese researchers managed in August 2020.NICT managed the feat by upgrading virtually every stage of the pipeline. The fiber optic line had four cores instead of one, and researchers fired a 552-channel comb laser at multi...

source:Mining technologyA fast-growing staple of the green energy revolution, rare earth elements are used to produce electric magnets found in everything from electric vehicles (EVs) to direct drive wind turbines. With tightening global emissions restrictions driving up demand for EVs, cashing in on deposits of rare earth materials is a savvy way to secure a seat at the table of the blossoming green economy, and finding alternative sources to China has become a priority amidst continued trade tensions.Peak Resources’ Ngualla project is based on one of the largest and highest-grade undeveloped...
