More than just a pretty face, this sexy polycarbonate (not very treehugger) cone purifies up to 1.5 l/day with nothing but a little sunshine. It's simplicity is impressive. Simply pour some brackish/salty water into the black base(see pics below), set it in the sun and the water evaporates upwards, condenses on the inner wall of the cone and trickles into a separate trough. Later you unscrew the top and pour the sucker into a bottle. Easy. I guess people would look at me funny if I did it on my roof in manhattan but it's tempting. I tell you...science is sexy.
