Hydride Heat Engine Prototype by Ergenics
Video shows two buckets of water — one hot, the other cold. As the two leads from the Ergenics aparatus are immersed into the two buckets, the temperature differential drives a turbine, powering a generator that powers the light. Ergenics is developing a metal hydride heat engine that converts the energy from hot liquid (eg solar hot water) into electricity for an estimated cost of less than 1¢ per kilowatt hour. For example, solar panels produce hot water which is pumped to a hydrogen compressor, that compresses a gas that is then expanded in a hydraulic motor-generator set that produces electricity. The technology has a multitude of other applications and iterations. Official website: www.ergenics.com Independent coverage peswiki.com
