Description: The candle-powered car is an application of the Seebeck Effect. This effect is the result of thermal energy conversion directly into electricity. This phenomenon can be used in elementary school to show energy conversion from heat to electricity to the kinetic energy of the car. A more detailed explanation will be required in high school related to electron response to temperature differences in different materials. The Seeback circuit used in this candle-powered car can also be connected to a voltmeter and used as a temperature sensing thermocouple.
