Annapolis, U.S.A. — Clean Wind Energy Tower, Inc. announced on July 23 the publishing of its patent titled Efficient Energy Conversion Devices & Methods by the United States Patent and Trademark Office.

The patent covers specific aspects of deploying multiple turbines in a wind tunnel coupled to a novel hydraulic system capable of maintaining high efficiency hydraulic to electric conversion under a wide variance of wind speeds. The ultimate goal is to maximize the capture and utilization of all available wind energy in any given wind tunnel, as well as providing a consistency of power output during any deviations in wind speed. The Company considers this patent to be a “Core Patent” providing a significant barrier to entry for any potential competitor.

Ronald W. Pickett, President, Chief Executive Officer of CWET previously stated, “Our innovative solution of extracting the maximum energy generated by the captured wind, with the least loss of power throughout the transmission cycle from capture to exhaust, produces a much more consistent level of power output while compensating for the normal differentials in atmospheric conditions over any given period, and should coincide with our customers’ requirements. The technological concepts and applications claimed and embodied within this patent provide significant benefits toward enhancing the level of efficient power generation, as well as reducing operational costs.

The annual capacity factor for the downdraft portion of the Energy Tower is predicted at approximately 51%. Prime production periods are daytime and evening during spring, summer and fall, which closely align with electricity demand patterns. However, the External Wind Capture keeps working 24/7, whenever a wind is blowing, including cold winter months and at night.

Its capacity factor is estimated at approximately 75%, which raises the Energy Tower’s overall capacity factor to above 60%. Clean Wind believes that the Downdraft Tower will be capable of recapturing and recycling the vast majority of the water used to create the downdraft. This water may be returned to be reused in the Downdraft Tower or diverted for local potable water.

As currently designed, the Company anticipates that each Downdraft Tower will be capable of generating up to 1,200 megawatts per hour of salable electricity to the grid.  One megawatt equates to 1,000,000 watts or 1,000 kilowatts of electricity. Currently, avoided costs per kilowatt in California are running approximately $0.11 per kilowatt hour.
