ABSTRACT:
A cryogenic thermoelectric generator preferably includes a thermoelectric transducer and a cold source (i.e., anything having a below-ambient temperature) thermally coupled to the "cold side" of the transducer. The cold source preferably includes a vessel adapted for containing a cryogen (i.e., a substance having a temperature no greater than 0.degree. C.). The vessel is operatively connected to the cold side of the thermoelectric transducer for thermally coupling a cryogen contained by the vessel to said cold side of the thermoelectric transducer, thereby inducing a temperature differential across the hot and cold sides of the thermoelectric transducer when the vessel contains a cryogen. The thermoelectric transducer produces electric power in response to the temperature differential. The thermoelectric transducer is preferably a semiconductor device, the cryogen is preferably a substantially pure liquid such as liquid nitrogen or liquid hydrogen, and the vessel is preferably a Dewar vessel.
