This is a really amazing heat powered fan. This uses heat to generate electricity and to move the fan around. This uses a thermal electric generator. This basically creates electricity from the temperature difference of the bottom and the top of the wafer board. This is a very cool science project and also has great applications for spreading heat around from a woodstove. #Woodstove #StoveFan #Heater #ThermalElectricGenerator #HeatElectricity
