A windmill for highly efficient wind power generation is provided by enabling one to efficiently rotate the windmill even in starting or at a low wind speed region by improving a blade of a vertical shaft type windmill of a lift type. In the windmill for wind power generation, a plurality of blades are provided in parallel with a rotating shaft in a face orthogonal to the vertical rotating shaft at constant angles centering on the rotating shaft, wherein the blade is of a blade type having a high lift coefficient at low Reynolds number and a notch portio...
The invention claimed is: 1. A windmill for wind power generation which comprises: a windmill for wind power generation comprising a plurality of blades with constant angles centering on a vertical rotating shaft in a face orthogonal to the vertical rotating shaft, wherein the blade is formed in an outer periphery thereof with a bent plate having a streamline shape, has a high lift coefficient at a low Reynolds number and has a notch portion formed therein along a predetermined length between a front edge and a rear edge of the blade. 2. The windmill...
