The clean, silent and completely self-powered SmartFan propels heat that is rising to towards the ceiling back into the living space, increasing heat circulation and fuel efficiency.  It works by using a thermoelectric generation module (TEM) to convert heat from the stove to an electric current that silently powers 2 fan blades. The hotter the bottom of the SmartFan and the colder the top, the more electricity is generated. By placing the SmartFan on the top section of a stove, it can move air up to a rate of 360 Cubic Meter per hour (200 Cubic Feet per minute).
