Arizona Green Power holds the license to a bold new clean energy technology that will provide an abundant source of ‘green electricity’ to California utilities, government entities, commercial and industrial companies and projects. Designed by world-class engineering partners, this patented hybrid solar-wind Downdraft Tower is not only revolutionary in design, but also in cost and durability. Tower construction is priced at roughly 1/3 of, and built to last twice as long as solar and/or wind farms – unheard of among renewable energy technology today.

The technology operates in hot, dry geographic locations. In certain areas where atmospheric conditions are conducive, the exterior of the Tower may be constructed with vertical “wind vanes” that capture the prevailing wind and channel it to produce supplemental electrical power. This dual renewable energy resource greatly enhances its clean energy-producing capability and productivity.

How it works

  • The Solar Wind Downdraft Tower is a hollow cylinder with a water injection system near the top.
  • Pumps deliver water to the Tower’s injection system where a fine mist is cast across the entire opening.
  • The water introduced by the injection system evaporates and is absorbed by the hot dry air which has been heated by the solar rays of the sun.
  • The air becomes denser and heavier than the outside air and falls through the cylinder, evaporating and cooling, increasing downdraft speeds to over 50 mph.
  • Air is then diverted into wind tunnels surrounding the base of the Tower.
  • Turbines inside the wind tunnels power generators to produce  electricity.
