Purpose:Demonstrate thermoelectric power generation or how thermoelectric devices can create hot and cold regions.
Description:Immerse the two aluminum legs in baths of different temperatures, and produce electrical energy that turns on the turbine. Unplug the banana jacks and measure the voltage output with a multimeter. This device is reversible. Connect a battery or DC power source to the two jacks. One leg will heat up while the other cools down. Measure the efficiency of this device and compare it to the Carnot efficiency.
