Abstract	The ground based wind energy extraction systems have reached almost their maximum capability. With the uncertainties related to wind like the variable wind directions and significant variation over shorter time scale has been a major hurdle in complete harnessing of this energy. The wind industry needs of revolutionary ideas to increase the capabilities of wind installation. This article suggests a revolutionary innovation of producing artificial wind of constant direction and controlled magnitude the constant and continuous wind from a single direction would make the wind turbines work longer span during a year there by producing a dramatic increase in power production. The artificial wind production works on same physics as convective downdraft in nature are produced. By definition, downdrafts are nothing more than areas of downward moving air. Their scale and intensity can vary driven by cooling due to melting and evaporation of precipitation, condensate loading, and pressure forces. A skyscraper sized hollow cylinder is used to tunnel down the natural downdraft created by cooling down the hot dry ambient air using evaporation cooling technique .as the air cools it become denser than outside air and falls down channelized by the tower at the speed up to (and above) 10m/sec. at the bottom this fast descending air is directed through wind turbines installed over the circumference of tower at base of the tower generating electricity. The magnitude of downdraft can be controlled by controlling its negative buoyancy and precipitation loading. Prime production time of artificial wind plants would be the daytime and evening during spring, summer and fall, thereby closely aligning with the electricity demand patterns. Additionally external vertical blade turbines would capture any wind blowing including cold winter months and night. At most optimised state the power generated is estimated to be approximately on an hourly basis, of approx. 500 megawatt hours, gross. Using a 70 percent capacity factor the Tower's potential hourly yield would be 350 megawatt hours from which, approximately 17 percent will be used to power its operations, yielding approximately 300 megawatt hours available for sale to the power grid.
