Is achieved by 350oC, over a 'p' and 'n' type semiconductor sandwich.
So no rare Earth metals. And the thickness of the p and n layers gives us great efficiencies. But we do not use waste heat, we fire us a 50x1cm steam plasma tube at 4 atmospheres, that turn 2x10-12cc of regular water into a constant 2.1MW of heat – our thermoelectric generator will turn into 144kW of carbon 0 heat. 1.2 million every year from the national grid.
Thermoelectric materials show the thermoelectric effect in a strong or convenient form.
The thermoelectric effect refers to phenomena by which either a temperature difference creates an electric potential or an electric potential creates a temperature difference. These phenomena are known more specifically as the Seebeck effect (converting temperature to current), Peltier effect (converting current to temperature), and Thomson effect (conductor heating/cooling). While all materials have a nonzero thermoelectric effect, in most materials it is too small to be useful. However, low-cost materials that have a sufficiently strong thermoelectric effect (and other required properties) could be used in applications including power generation and refrigeration. A commonly used thermoelectric material in such applications is bismuth telluride (Bi
