The Thermoelectric Generator

The ability of a thermocouple to generate a voltage when there is a temperature difference across it suggests its use as a heat engine capable of producing electricity directly. As a heat engine, its efficiency is limited by the Carnot efficiency, and therefore it must be of the form

where n* depends on the geometry of the device, on the properties of the materials used, and on the matching of the generator to the load.
