Giant downdraft tower might create 500 MW of power

Solar Wind Energy hopes to construct a 2,250-foot-tall, wind-powered tower on the Arizona-Mexico border that would generate 500 megawatts of power. The project, which consists of the $1 billion tower, a plan to pipe desalinated water in from the Sea of Cortez in Mexico and a desalination plant, is expected to create 2,500 construction and transportation jobs.

The sinking air can accelerate to 50 mph and then exit the tower and spin turbines.
