Power towers/innovative method of power extraction using static airfoils
Abstract:
An airfoil shaped tower the size of a skyscraper for the production of electrical power using turbines. The turbines are located at the base of the tower and are fed by ambient air. Power to turn the turbines comes from the pressure drop generated by the wind moving over a changing surface of the airfoil. (Bernoulli's Equation). The areas of negative pressure on the exterior surface are covered by a plurality of bleeder vents that conduct air from the high-pressure (ambient air) interior to the low-pressure exterior. The invention is further improved by the construction of several towers in close proximity. Adjacent towers augment the air velocity thus increasing the pressure differential. The power of the turbines is greatly increased because power is proportional to the effective wind velocity cubed.
