Via: Physorg: The tower that SWET has in mind is located in a hot dry area. The tower structure is a hollow cylinder reaching skyward into the dry atmosphere heated by the solar rays of the sun. The water introduced by the injection system near the top of the Tower evaporates and is absorbed by the hot, dry air. The air becomes cooler, denser and heavier than the outside warmer air and falls through the cylinder at speeds up to and in excess of 50 mph. The air is diverted into wind tunnels surrounding the base of the tower where turbines inside the tunnels power generators to produce electricity. (Each tunnel has a dedicated generator-room, with multiple-sized generators, powered by the patented drive system. The tower produces clean electricity, 24 hours day and night, 365 days a year.)
