Candle Car - Runs by Thermoelectric Effect

This little vehicle is candle powered! The candle heats one side of a Seebeck cell, and this produces electricity via the thermoelectric effect. The current runs the little electric motor, and off the car goes! More electric power is produced when the temperature difference is greatest across the Seebeck cell, so while the candle heats the underside of the cell, water and a little ice in the metal container at the top cools the other side of the cell.
