Powerspot. The Seebeck Effect In 1821 Thomas Johann Seebeck discovered the thermoelectric effect: Seebeck, in 1821, discovered that a compass needle would be deflected by a closed loop formed by two different metals joined in two places, with a temperature difference between the junctions. This was because the metals responded to the temperature difference in different ways, creating a current loop and a magnetic field.
Powerspot. Thermoelectric modules A thermoelectric couple is a device consisting of two dissimilar semiconductors that contact each other at one or more points. Voltage is produced when the temperature of one of the contact points differs from the temperature of another, causing the electrons to move away from the hot end toward the cold end. When the electrons go from the hot side to the cold side this causes an electrical current.
Powerspot. Our generators. Powerspot generators use thermoelectric technology based on Seebeck effect to produce electricity. One or more thermoelectric modules are built into the base of our generators. They have no moving parts or batteries. A direct current is produced when the base of the generator is heated and the upper part is cooled. Any source of heat can be used to generate electricity.
