Thermoelectric Generators
Thermoelectric generators (TEGs) are devices that convert heat directly into electricity using the Seebeck effect. They consist of thermoelectric materials that generate a voltage when there is a temperature difference across them. In space and astronautical engineering, TEGs are used to power spacecraft and satellites, as they can generate electricity from the heat produced by the decay of radioactive isotopes or from the waste heat generated by electronic components. TEGs are also used in space suits to power various instruments and equipment. The efficiency of TEGs is limited by the thermoelectric materials used, and research is ongoing to develop new materials that can improve their performance.
