Thermoelectric Demonstrator with Power Supply

Thermoelectric Demonstrator Reversible with Power Supply Thermoelectric Demonstrator Reversible with Power Supply. To demonstrate conversion of heat energy into electrical energy and vice-versa. Amaze everyone with this apparatus, showing how power is generated on some space crafts like the Voyager. Consists of two Aluminum Strips joined together with series connected semiconductors. Upon immersion of one leg in cold water and the other in hot water you can see the fan turn as the connected motor gets current. The generation of electricity can also be seen if a multimeter is connected to the two 4mm sockets. Now, if the process is reversed and a dc current of 6V-2A is given to the unit thru the two 4mm sockets, then one of the strips will heat up and the other will be cold, demonstration of refrigeration. Unit is approximately 9"(23cm) tall, and the strips are 1.5"(40mm) wide. Supplied complete with two containers, a pair of 4mm banana plug leads and (# 2037-3) Variable Power Supply 2v-12V, 2A .
