The discussion in that article is about a technology that concentrates the solar energy to melt "salt" .this molten "salt" is then used to boil water to drive steam turbines. I know a bit out this. While in theory the water is condensed and resumed, it is the sent to cooling towers. The result of this is the need for a lot of really clean makeup water.
I suspect the lack of water resources in a desert actually makes this recnically I feasible.
