THERMOELECTRIC GENERATOR

摘要

The invention provides an improved thermoelectric generator. It consists of an air-tight vessel containing a vacuum with a cathode made out of an electron emissive material and anode which is made out of an electron absorbing material. A high voltage potential is supplied between the cathode and anode. When a cathode is heated by an external heat source, electrons ar e generated and directed towards the anode, creating an electrical current.
