Very High Temperature nuke reactors (VHTR) are perfect for combo electical generation/desalination, as heat is the main requirement for desal. Cheap clean electricity and fresh water.
As I recall there is a San Diego company who can build VHTRs.
Millions of acres of Colorado river farm land are already fallowed each year to provide drinking water to SoCal. It does not look like its going to improve anytime soon, so why no nuke desalanation plants in Obamas stimulus? That seems like a good way to put people to work and future generations get more than just a tax bill;
they get cheap electricity, jobs and fresh water?
