Thermoelectric Converter

A series of semiconducting junction plates are sandwiched between 2 aluminum heat-conducting plates. There is a switch on the thermo converter to alternate the junction plates between the motor fan or a pair of 4 mm sockets. When the 4 mm sockets pair are selected and driven with a 5 V DC voltage, a temperature difference will be created and conducted by the aluminium plates. When a temperature difference exists between the 2 sides of the junction plate, electric current is generated to drive a little fan, providing a visual demonstration of the current produced.
