	History
		Thermoelectric generators are solid-state power sources that utilize the Seebeck effect, while thermoelectric coolers are solid-state heat pumps utilizing the Peltier effect.
		A thermoelectric converter consists of a number of alternate n- and p- type semiconductor thermoelements, which are connected electrically in series by metal interconnects, sandwiched between two electrically insulating but thermally conducting ceramic plates to form a module.
		Thermoelectric generators could eventually be used to waste heat, such as that produced by combustion in an automobile, to electricity.

	THERMOELECTRICITY - Online Information article about THERMOELECTRICITY
		Law of Intermediate Metals.—A thermoelectric circuit may be cut at any point and a wire of some other metal introduced without altering the E.M.F. in the circuit, provided that the two junctions with the metal introduced are kept at the same temperature.
		Thermoelectric Formulae.—On the basis of the principles stated above, the most obvious method of tabulating the observations would be to give the values Et of the E.M.F. between o° C. and t for each metal against the standard.
		The first relation gives the thermoelectric power p at any temperature, and is probably the most convenient method of stating results in all cases in which this formula is applicable.
