摘要

Since 2018,Turntide Technologies'highly efficient electric motors-based on an updated version of an early 19th century design-have turned cooling fans in dairy barns across the United States;in addition,more than a dozen companies,including BMW and Amazon,have saved an estimated average of 64％on heating and cooling costs by retrofitting their rooftop heating,ven-tilation,and air conditioning(HVAC)systems with the company's"smart motor system"[1].Now,as announced in June and July 2021[1,2],the Sunnyvale,CA,USA-based company,backed by Bill Gates and Amazon,is shifting its focus to electric vehicles(EVs)after securing 225 million USD in funding and acquiring three startup firms-Hyperdrive Innovation,BorgWarner Gateshead,and Avid Technology-that make batteries,drivetrains,and EV controls,respectively.
