Windmill generator apparatus
A duct possessing structure includes an annular first floor and an annular first roof disposed substantially horizontally, vertical stationary guiding partitions provided radially between the first floor and roof, and a centrally located hollow cylindrical space. A revolving body includes a circular second floor and a circular second roof, and a pair of guide pillar members disposed between the second floor and roof. Each guide pillar member comprises a duct-blocking arcuate outer wall along the outer circumference of the second floor and roof, and a ductforming curved inner wall connecting both side edges of the arcuate outer wall. The revolving body is disposed within the hollow cylindrical space of the duct possessing structure and is adapted for rotation about an axis coaxial with that of the center axis of the cylindrical space. A windmill is supported for rotation within a hollow space, defined by the floor, roof and the pair of guide pillar members of the revolving body, and about a vertical axis which is the central axis of the hollow space. A generator is connected for rotation with the horizontal rotary shaft of the windmill, and wind directional means is provided for turning the revolving body to point the windmill in the windward direction.
