WebThe turbine can drive a generator, which produces electricity. This setup is very common, but it requires a fair amount of equipment and space. If you would like to generate electricity from heat in a simple way that has no moving parts, this usually involves thermocouples. Thermocouples take advantage of an electrical effect that occurs at ... Web21 de nov. de 2024 · For example, you can convert electricity to the mechanical energy and back with little losses, such in hybrid electric cars. You can also convert a low-entropy energy to a high-entropy energy. For example, an electric heater converts electricity to heat 100%. The same way friction converts the mechanical energy to heat 100%.
