The Ecofan is a heat powered fan that circulates the warm air from a wood burning stove, without using batteries or mains power. The Ecofan's power comes from a thermoelectric module, a small generator with two semiconductors. When there is a difference in temperature between the two semiconductors, this causes a current to flow which is used to power the motor of the Ecofan. This is known as the Seebeck effect.
