Wind-powered electricity generator for buildings - has wind turbine mounted on opposite sides of wall or roof surface

摘要

The generator has at least one wind turbine (8) fixed to the external facade (2) or the roof of the building. The drive shaft (6) between the wind turbine (8) and the generator (9) is supported by a bearing (5) fitting through a plate (4) attached to the rear of one of the outer walls or the inside of the roof. Pref. the mounting plate (4) is bolted to the rear of a suspended facing wall (2) with a conversion gearing (7) between the end of the drive shaft (6) and the external wind turbine (8), the drive shaft (6) extending orthogonal to the plane of the wall (2). The wind turbine (8) projects sufficiently from the wall surface to lie in the path of the air currents running across the wall (2). The generator system can be used to provide the electricity for an office building, school,.
