A Threewheeler with Thermoelectric Drive The Candle Car Kit kit demonstrates the direct conversion of heat into electrical energy via the Seebeck effect. Like in photovoltaic cells the generation of electricity results from processes on an atomic scale without macroscopic movement of mechanical parts. The atomic vibrations that correspond to heat result in a gradient of the electron's distribution i.e. an electrical voltage. The Candle car is powered by a food warmer candle. Put the car on a flat and smooth ground, fill the upper reservoir with cold water (about one third) and light the candle. The resulting temperature difference between both sides of the thermogenerator produces electricity supplying the electrical motor on the front wheel. After a minute or two the car starts moving and slowly speeds up. It moves on a straight path or turns around in circles, what is adjustable via twisting the middle joint

The Candle Car is powered by a food warmer candle. Put the car on a flat and smooth ground, fill the upper reservoir with cold water (about one third) and light the candle. The resulting temperature difference between both sides of the thermogenerator produces electricity supplying the electrical motor on the front wheel. After a minute or two the car starts moving and slowly speeds up. It moves on a straight path or turns around in circles, what is adjustable via twisting the middle joint. The car's speed increases by using cold water from the fridge or adding some ice cubes.
