This experiment uses the thermoelectric effect and the peltier effect to demonstrate the power a thermoelectric generator can create. The experiment was set up with two cups, one full of boiling water, the other full of cold water. The difference of temperature between these two cups was converted into electric voltage, which was measured with the peltier device. When we put the two sided device into the cups of water, we waited for the voltage to reach its highest value, which was .5. We then recorded the temperature of the waters and the voltage for every assigned interval. We recorded it into an excel spreadsheet, which calculated the current and power in watts(P=I*V). Below is the excel document:

The experiment was done on a small scale, but it educated us on the peltier and thermoelectric effects. It was clear that when the hot temperature decreased and the cold temperature increased, less voltage and power was created. Therefore, the necessity for a drastic difference in temperature was addressed within the experiment. Whether or not increasing or decreasing temperatures in the water to begin with will directly affect it remains to be unseen. The experiment was well thought out and organized clearly. It also provided me with further knowledge of the different ways we can provide electricity using less harmful methods for the environment.
