When you are thirsty, you just grab a cup and turn on a faucet, right? But what about people in third world countries? Their main source of water is from wells, or from rivers clogged with pollution and waste. Sickness such a cholera is common because of the lack of clean water. When I conducted this experiment, my first goal was to build two identical water distilling devices. Unfortunately, I ran out of time, and only managed to build one distiller. I was disappointed, because this meant that I would have to change my topic. But a thought occurred to me: what if I just tested the use of the lens on a pot of water? I wouldn't be able to make any clean water, but I could find out if the water would even boil. My hypothesis was incorrect, however. The experiment was an overall success though. I found out that the use of the Fresnel lens is optimized when the sunlight is constant and intense. The outside heat didn't affect my experiment very much, so I plan to conduct my distilling experiment next summer when the temperature is better, and there is more sunlight.
