A thermoelectric power generator, also called TEG, is a device that can convert heat (temperature differences) directly into electrical energy. The device is able to do this through a phenomenon that’s called the Seebeck effect ( that’s why it is also widely known as a Seebeck generator). Practically, a thermoelectric generator functions like a heat engine expect that there are no moving parts and they are less bulky.
And because they TEDs are typically more expensive than efficient, it’s a good idea to build one by yourself. This DIY thermoelectric power generator features only 1 Peltier module(40×40) and uses a boiled water and only a small amount of cold water.
