Thermoelectric generator Wikipedia

A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect).Thermoelectric generators function like heat engines, but are less bulky and have no moving parts.. However, TEGs are typically more expensive ...

ThermoElectric Generators

The Scott thermopile, which sounds like an American design, is unknown to Google. From Transactions of the American Electrochemical Society Volume 6, 1903: "The cell was connected in series with a galvanometer and a 66element Gulcher thermopile. The thermopile was lighted and simultaneous readings were taken of the current and the ...
