nice, but not so cool as the folk who found out that after years of thinking up dificult solutions to bring clean water to africa it turned out you can just as well put some water in PET Bottles on an tin roof. as long as you are near enough to the equator and there is enough sunlight in a few hours the UV radiation in the sunlight will kill all microbes
