Generate electricity using nothing more than a combination of hot and cold water and a special conversion cell. As the temperature evens out between the two containers of water, the power level reduces. LED and mini turbines demonstrate the variance in the electrical power being generated and there are two thermometers to keep track of the temperature levels. Produce power from temperature difference (hot/cold water). LED and fan modules show variance in electric power being generated. Examine the physics of heat exchange and the energy that can be captured. Comes with CD, experiments, curriculum, and 2 thermometers.
