Heat electricity
Thermoelectric power generators consist of three major components: thermoelectric materials, thermoelectric modules and thermoelectric systems that interface with the heat source. Thermoelectric materials generate power directly from the heat by converting temperature differences into electric voltage. These materials must have both high electrical conductivity (σ) and low thermal conductivity (κ) to be good thermoelectric materials. Having low thermal conduct… WebElectricity is at the heart of modern economies, its share of final energy consumption over 50% by 2050 as electricity demand increases rapidly.
