At the base of the heatsink is an array of several hundred thermocouples (Peltier module). On top of the heatsink is a small 5 volt motor connected to the array. The temperature difference between the top of the array on the heatsink and the bottom, on the wood burning stove, produces enough electricity to drive the motor. I'm looking for a much bigger fan though. This would be much more efficient with a 12" brass fan! It would cool the heatsink better and circulate the air around the room improving the efficiency of the wood burner.
