Thermogenerator

Thermogenerator

Thermogenerators are devices which convert heat (temperature differences) directly into electrical energy. For the most part, this term is synonymous with "thermoelectric generator" and rarely used in English. They most commonly work on the principle of the Seebeck effect, with typical efficiencies of around 5-10%. Older Seebeck-based devices used bimetallic junctions and were bulky while more recent devices use semiconductor p-n junctions and can have thicknesses in the millimeter range. These are solid state devices and unlike dynamos have no moving parts other than sometimes a fan. Fuel such as natural gas, propane or kerosene can thus be used to generate DC electricity, which can be converted to AC by an inverter.

Applications

The use of waste heat in combustion engines promises to be a high volume application field. Not only the exhaust but also cooling agents are targeted. [Recodrive News [http://www.recodrive.eu/window.phtml?id=1089#293 source] ]
