This article describes some of the fundamental aspects of thermoelectric power
generation, which employs low-temperature heat sources to create electricity.
The focus is on a potential system design and viable thermocouple materials.
regarding generator design, a system is proposed that uses forced-air
circulation and a multistage heat-exchanger to efficiently convert the heat
content of a low-grade heat source into useful electricity. As for thermocouple
materials, both p-type Fe-12.8Al-12.7Si and n-type Fe-12.3Al conductors exhibit
significant thermoelectric power-conversion capabilities, making them ideal
candidates for use in the proposed power-generation system.
