cakilmer writes "I visited the Annual American Membrane Technology Association meeting in Las Vegas last week. These membranes support water desalination. 15 or 20 new plants are in planning stage to be built along coastal California. But there's no new water sources for the southwest. People are still streaming in and the big Hoover dam is half full and falling. What to do? The answer is to invest the money to collapse the cost of water desalination and transport so water in the western deserts is as cheap as water on the East Coast. Is this doable? You bet."
