New Way Found To Make Electricity From Wasted Heat

February 4, 2021 | Leave a Comment

Karlsruher Institut für Technologie (KIT) scientists have now come much closer to their goal of converting waste heat into electrical power at small temperature differences. Electrical power per footprint of thermomagnetic generators based on Heusler alloy films has been increased by a factor of 3.4. The use of waste heat would contribute in a large […]
