1. Students will examine the properties of solar water pumping systems using KidWind solar water pumps or similar water pumps.
2. Students will experiment with the properties of water and its limitations in circulating due to pump power and distance.
3. Students will evaluate the use of a heat sink/chiller in the circulation of water through the bioreactor.
Solar energy is available when the sun shines but energy can be supplemented at night by the decomposition energy in a bioreactor. In this activity we will experiment with the feasibility of using heated water in a bioreactor to circulate it through a water trough or pipe system to prevent it from freezing in the winter. This method will save... View full description >>
