Solar Stills

Our group is now planning on making something called a solar still. A solar still is a great way to clean water. You pour water in, and the water evaporates to the top. Then, the evaporated water slides down to the clean water part. The water falls, and eventually makes enough drinking water. Cool, huh? The only problem is that it might take a while, and some of the water is evaporated completely. We also need to try to find a way to get the water to them without them walking so far. Some problems that we need to work out, but we're doing okay. Another problem is that we need to customize it so it is our own creation. I have included some designs, and have them for you right here:
Both of them are different, but they have the same concept.
