• Solar Power Charges Wind Power Plant in Arizona


  • The Clean Wind Energy Downdraft Tower is a skyscraper-sized wind power plant powered by solar energy. It has close to zero carbon footprint, produces almost no waste and consumes virtually no fuel. By harnessing the power of the sun to make wind energy, it can be used in areas with little breeze of its own. It works like this: a fine mist of water is sprayed across the top of the hollow tower to cool hot air as it enters, as it cools, it falls more heavily and faster, so by the time it reaches wind turbines at the bottom, it is powerful enough to generate electricity. This first tower in Arizona could make up to 1000 megawatts of energy per hour, approximately 600 megawatts of which would go back into the national grid.

    The tower is currently in the semi finals of the Future Energy Pitching Event in Washington, DC.
