Solar Wind Energy Downdraft Tower project moves ahead (Video)

Solar Wind Energy Tower, Inc. (SWET), is collaborating with Providence Energy Corporation, a privately-owned company from Dallas, Texas, on the development of the first Solar Wind Energy Downdraft Tower (See Video Demo below) located in San Luis, Arizona on the US/Mexico border. 

The simplicity of this hybrid solution is comprised of harnessing the natural power of a downdraft created within the confines of the Solar Wind Downdraft Tower structure, a hollow cylinder reaching skyward into the hot, 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 and is diverted into wind tunnels surrounding the base of the Tower where turbines inside the tunnels power generators to produce electricity.

Ronald W. Pickett, CEO, stated, "We have been in discussions with Providence Energy for several months about the development of our first Downdraft Energy Tower project in Arizona. Providence Energy and their various subsidiaries have extensive experience and expertise in partnerships with energy exploration, production, generation companies, as well as renewables across the Americas. Providence Energy has taken a position in Solar Wind Energy Tower, Inc., and we welcome their expert development assistance in making our first Tower Project a reality."

SWET has successfully managed to downsize and economize the Tower, reducing expected capital costs and improving projected financial performance. The completion of weather data models confirm the first tower height can be lowered from 3,000 feet down to 2,250 feet.  This development was made possible by utilizing our recently announced software which can calculate and predict energy production by our Solar Wind Downdraft Towers given local weather data. By feeding the weather data for southwestern Arizona/ Northern Mexico into the program, the Tower's height and diameter can be adjusted along with the amount of water added as fuel to create a desired amount of energy. The outcome dictates the optimum size of the Tower’s height and width.

Under the most recent design specifications, the first San Luis Tower is expected to have a design capacity on an hourly basis, of up to 1,250 megawatt hours, gross.  Using a 60% capacity factor, we expect the Tower's potential hourly yield equates to 600 megawatt hours, from which approximately 18.5% will be used to power its operations, yielding approximately 500 megawatt hours available for sale to the power grid. Factoring in lower capacities during winter days, the average daily output for sale to the grid for the entire year is approximately 435 megawatt hours per day. Currently in California avoided costs are running approximately $0.11 per kilowatt hour.  As an independent power producer of clean renewable energy, SWET will be selling power directly to the power grid rather than directly to consumers.
