The reason this isn't being done much, is it takes a lot of energy to do it. So, a shortage of water is really a shortage of cheap energy. Figure out cheap, abundant energy, and water problems are solved.

For those of us who live on the coast it's no problem, especially if it's next to a desert. (or if you have a lot of wind) In the desert such as in Saudi Arabia and Northen Africa they could do Desertec and from creating all of that electricity generate gobs of fresh water as a byproduct.

(and they don't need to steal hardly any electricity from solar thermal to do it.)

Condensation cycle.

Desert next to salt water = lots of electricity and fresh water.

How much do you want?

Jacob, see my reply to Eric on the desalinization issue.

It is nowhere near as straightforward as some people believe to do it a really large scale. And transporting water--which is far heavier than oil--is not a simple matter either, even though it obviously can be done.
