The NASA spacecrafts Voyager 1 and 2 became household names overnight following the showing on television of the remarkable photographs of the rings of Saturn and more recently of Neptune and its mysterious moon, Triton. None the less remarkable is the source of electrical power which enables...

The increased activity in attempts to develop improved thermoelectric semiconductors for use in the direct conversion of heat into electrical energy results mostly from research sponsorship by the US Military and NASA. Thermoelectric generators have no moving parts and are difficult to detect by...

During the winter months in regions where constant electric power supply cannot be relied upon, power may be derived parasitically from heating stoves. A proportion of heat from these 20–50 kW wood or diesel-heated stoves may be utilized to drive a thermoelectric generator (TEG) consisting of...
