  2. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator ( TEG ), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect ). Thermoelectric generators function like heat engines, but are less bulky and ...

    en.wikipedia.org/.../Hydrogen-cooled_turbo_generator

    The first range (80–100% H 2) is to monitor the hydrogen purity during normal operation. The second (0–100% H 2) and third (0–100% CO 2) measuring ranges allow safe opening of the turbines for maintenance. Hydrogen has very low viscosity, a favorable property for reducing drag losses in the rotor. These losses can be significant due to ...
