:: There is also the thermoelectric effect, which has some similarities to the photoelectric effect, but it is even less efficient in practice . talk ) 17 : 00, 8 June 2009 ( UTC)

To understand the microscopic origin of the thermoelectric effect, it is useful to first describe the microscopic mechanism of the normal Ohm's law electrical conductance to describe what determines the \ scriptstyle \ sigma in \ scriptstyle \ mathbf J =-\ sigma \ boldsymbol \ nabla V.

I one time brought the topic to my physical science teacher of why we couldn't just use concentrate the exhaust of the air conditioner to a heating point and use the thermoelectric effect to generate current to help alleviate the apparently expensive energy costs of using energy to . . . remove heat energy from the air.

TSC based on a temperature gradient is also known as " Thermoelectric Effect Spectroscopy " ( TEES ) according to 2 scientists ( Santic and Desnica ) from ex-Yugoslavia; they demonstrated their technique on semi-insulating gallium arsenide ( GaAs ) . ( Note : TSC based on a temperature gradient was invented before Santic and Desnica and applied to the study of organic plastic materials.
