Cheap Lee Valley Ecofan UltrAir

This ingenious stovetop fan for wood-burning stoves is completely silent and costs nothing to operate. Based on a phenomenon known as the Seebeck effect, the fan uses thermocouple technology to generate an electrical current by exploiting the temperature difference between the stovetop and the ambient air. The fan speed varies with the temperature difference (greater difference, greater speed), quietly moving warm air from the stovetop. Made largely from anodized aluminum, it is an efficient way to disperse heat.

The fan can produce up to 125 cfm of air movement, stands 9″ tall and has an 8″ diameter brass blade; it operates on surface temperatures from 212° to 650°F (100° to 345°C).
