ABSTRACT:
A horizontal multidirectional turbine windmill comprising a housing having apertures on all sides for ingress and egress of air and a rotor on a drive shaft within the housing, each aperture being the larger end of a funnel-shaped passage, the smaller ends of said passages being positioned to deliver air at relatively high velocities against the rotor buckets, the air entering the housing through one or more apertures on the windward side thereof and being exhausted through apertures on the leeward side. The housing is preferably so shaped that ambient air impinging on the housing surface without entering an aperture will flow around the housing and create a low pressure zone adjacent the exhaust funnel apertures, and the housing is also preferably so shaped that a plurality of units can be stacked vertically with their drive shafts coupled together. The rotor buckets may be flexible, with provision for varying their profiles automatically as a function of wind and rotational speed.
