Closed loop multiple airfoil wind turbine
摘要:
Disclosed is a multiple blade wind turbine (MBWT). The MBWT includes: at least one rotor comprising two closed loop tracks positioned parallel or equidistant to one another and a plurality of airfoils interspaced within the tracks. The plurality of airfoils are connected at each end to one of said tracks and are fully rotatable with respect to said closed loop tracks. A transmission is connected to one of the tracks. The track drives the transmission and an electric generator is connected to said transmission for generating electricity. The rotors are oriented vertically or horizontally with respect to a vertical support structure that is used to support the rotors. The MBWT's design allows the electric generator(s) and transmission system to be housed relatively close to ground level. This configuration reduces the mass of the central support tower and reduces the construction and ongoing maintenance costs.
