Thermoelectric Generator With No Moving Parts

Savage-Rabbit writes "These guys have produced a working prototype of a thermoelectric generator. The thing uses extremely cold and hot liquids to achieve a heat transfer through a semiconducting material. This produces a voltage in the semiconductor who can produce up to 50-100 Watts which is actually enough for this thing to have practical uses. This generator could for example be useful in the chemical industry where many production processes generate a lot of excess heat that normally is simply lost. With a thermoelectric generator some of that lost energy could be recovered."

This is just a Peltier device in reverse. Instead of using a forced flow of electrons to drive heat from a cold surface to a warmer one, it is using the flow of heat from a warm surface, through the Peltier element, to a colder surface to drive electrons, generating current.
