Thermoelectric converter. Peltier element. Alternative energy.

Friends! I did an experiment with the Peltier element. Cold and hot water is poured into two containers , between which a thermoelectric Converter is located (you can add a little ice to the cold water to increase the visibility of the process). The higher the temperature difference , the faster the fan will start to rotate. You can find theoretical notes for this experiment in my Instagram at the link If you are interested in my experimen
