Abstract
Abstract A guided flow wind power machine having inter-meshing tubular fan blades is disclosed. The device includes a main frame which is rotatively mounted to permit it to continuously face the wind directly. The main frame carries three separate power cells each having a plurality of tubular fans, all of which are inter-connected to drive a non-linear alternating current generator. An energy storage system is also disclosed and includes a plurality of massive weights that are raised hydraulically to store excess power generated by the fans. Power is withdrawn from the storage apparatus by permitting the weights to act against the hydraulic system to drive a reversible pump-motor.
