#### Abstract

How can the water temperature be reduced inside a tank in hot weather (52°C), while reducing the water temp from 45°C to 25°C within approximately 30 minutes using green energy? I tested a simple solution to the problem of cooling the water using a fan that blows air along the top of the water surface. We arrived at a solution by testing two different fans. We first tested a small fan with reasonable amount of air flow; and conducted an experiment with this fan. Based on different times and temperatures, the small fan was able to reduce the temperature of the water faster than the time we set before. We performed the same experiment but used a bigger fan; the results were different and not expected. The smaller fan had a faster cooling time compared with the bigger fan. The speculations on these findings: that the smaller fan has more laminar flow than the bigger one. Finally, the smaller fan was the right one to use since it has better results. Also, building an air duct to connect the fan to the tank was good idea. The main source of energy is solar panels. These findings could help people in the future to create green cooling systems.
