• a heat engine which converts a heat difference directly into electric power.
• a sensor device embedded on high power microprocessors used to monitor the temperature of the processor's die.

There are two types. One uses semiconductor thermocouples, working on the principles of the Peltier-Seebeck effect. The other relies on vacuum tubes and the principles of thermionic emission.
