The production of energy often results in losses due to surplus heat. Düsseldorf cleantech start-up poligy has come up with a solution for harvesting waste heat and converting it into electricity.
The technology uses relatively low heat to bend and flex strips consisting of two different polymers fused together (“Bipolymers”) to generate green electricity through motion. According to poligy, its solution is cheaper than solar units.
The German Energy Agency estimates that by avoiding or using waste heat Germany could save up to 37m tons of CO2 a year.
