A thermoelectric fan is powered by a candle using the thermoelectric effect. A thermoelectric module generates voltage from the temperature difference between its hot and cold sides. In the fan, a candle heats one side of a module, while a CPU heatsink cools the other. The voltage powers a motor that spins a fan, circulating air to maintain the temperature difference and continue powering the fan. The design aims to use a candle's waste heat to power an electric air circulator in an efficient yet simple homemade project.
