For a science project, I plan to come up with a reliable way to produce clean water from the sun. I've toyed with ideas of using fresnel lenses and parabolic concentrators, but none of them solved all the problems I had. Then, I thought of using multiple—and when I say multiple I mean about 300+—small mirrors to reflect light. Would this work? Reflect it all to a point—or a blotch, since points are technically impossible with diffraction—and boil water, the condense it in a different chamber? It would be cheap and easy, as well as efficient. However, since it's a project, I don't want to do it for nothing. Would it work?
