How? Every type of good water filtration or distillation requires energy in the form of pressure, heat, or electricity.
It's like the whole hydrogen powered car theory. Where does all the hydrogen come from? Electrolysis. And the power for the electrolysis comes from where? Coal or petroleum fired power plants. Doh...
Yes, there are solar powered methods of water seperation, but last I knew, were not scalable to the levels required for a hydrogen based economy.
