New thermoelectric superlattice doubles rate at which waste heat is converted to electricity

Researchers from Hokkaido University and colleagues in Japan and Taiwan have improved the ability to transform wasted heat into usable electricity by narrowing the space through which spread electrons move, according to a new study published in Nature Communications. Currently, more than 60 percent of the energy produced by fossil fuels is lost as waste… Read more »

ZF’s Axle Hybrid concept electrifies its AMT to improve shifting performance

German automotive supplier ZF has unveiled a new Axle Hybrid concept which uses an electrified Automated Manual Transmission (eAMT). This system combines ZF’s traditional electric axle drive system (eVD) with its automated manual transmission (AMT). The eAMT eliminates tractive force interruption and features AWD capabilities. “With eAMT, ZF has developed a fully-fledged plug-in hybrid drive for front-transverse vehicles,”… Read more »
