This works best with inexpensive energy

Water shortages are going to be an increasing problem, especially with desert countries adding suburbs on artfully-chased dredge fills.

So what to do? DESALINATE!!

Better desalination technology key to solving world's water shortage

As I suspected:

"The globe's oceans are a virtually inexhaustible source of water, but the process of removing its salt is expensive and energy intensive," said Menachem Elimelech, a professor of chemical and environmental engineering at Yale and lead author of the study, which appears in the Aug. 5 issue of the journal Science.

Yes, indeed it is. So it needs lots of energy -- where to get that? Where, I wonder, WHERE?

Solar and wind are going to come up short to meet the energy demands of wide-scale, high volume desalination. Nuclear energy can meet those demands.
