LOL. Where the hell is this in the discussion? Some time ago, b_b and I designed a solar-powered desalinization rig. I have all the parts in my garage. Maybe I'll throw it together soon and post about it.Supplying all domestic water by sea water desalination would increase US Domestic energy consumption by around 10%, about the amount of energy used by domestic refrigerators[15]
It's as pure as evaporated water gets (which should be eminently drinkable). The basic premise is a personal use system that poor people in areas near the ocean could use. The waves push water in, and the sun dries it out. Simple. It's basically concentric clear plastic channels with some modifications for letting water in and out.
This is quite saucy, too, for those far from the coast: http://www.gizmag.com/airdrop-wins-james-dyson-award/20471/
