The aim of this activity is to obtain electrical energy with the difference of temperature by running reverse operation. People living in Alaska use fossil fuels for electricity. In this study, the temperature in Alaska during the day - 28 C, while at night -60 C degree decreases. Considering that the internal temperature of the house is +26 degrees and above, a 4 cm2 peltier is generated by a peltier and the energy energy is 4m2 + 4m2 = 8m2. At the event, temperature values will be collected by using TI-Inspire CX CAS and two temperature probes to determine the ideal temperature value for generating electricity.
