An improved wind collecting apparatus utilized for transforming wind energy to rotary motion. The rotary motion is then used to drive an electric generator or the like. The apparatus generally comprises four semi-cylindrically shaped wind collecting blades connected to a shaft which is mounted for rotation about an axis of rotation and wind deflectors are positioned near the blades for directing portions of the wind. In one embodiment, the shaft is disposed in a plane substantially parallel with the earth\s surface and, in one other aspect, the blades are mounted for rotation generally above a cavity formed in the earth\s surface. The present invention also contemplates an improved blade structure.
