Heating or cooling with the turn of a crank!
This fascinating accessory demonstrates the Peltier effect - the absorption or emission of heat energy when electrons move from one state to another across dissimilar semiconductor junctions. Just connect it to the Genecon, turn the handle in one direction, and the plate heats up. Reverse direction and the plate cools down!
Thermoelectric circuits such as this allow temperature control when size or economics make normal cooling techniques impractical. They are used on circuit boards to cool components and in picnic coolers powered by car cigarette lighters. For an added challenge, ask your students to suggest more important or diverse applications for the device.Size: 1.5in X 1.5in
