Thermoelectric generation using a Peltier Module to utilize the Seebeck effect to generate voltage. When heat is applied to one of the two semiconductors, heated electrons flow toward the cooler semiconductor. If the pair is connected through an electrical circuit, direct current flows through that circuit.
