The company's skyscraper-sized "Downdraft" towers are 2,250-feet tall and each can generate electricity for 1.6 million homes, the company claims.
Solar Wind Energy Tower Inc. (formerly called Clean Wind Energy Tower (CWET.PK)) has two demonstration towers planned for Arizona and plans for a second pair in New Mexico.
The tower is a hollow cylinder with a solar-powered water spray system at the top that creates a fine mist along the opening.
As the mist cools the air, it becomes heavier and falls through the cylinder at speeds of up to 50 miles per hour. This manufactured "wind" drives turbines at the base of the cylinder, generating electricity. The design also allows for external vertical wind turbines, which would increase the generating capacity.
