Small wind-power plant for use in roof for supply of power in e.g. two family house, has rotor blades rotating in winding direction and against wind, when sides of rotor blades faces wind direction, respectively
The plant (1) has three concave/convex rotor blades (4) arranged in a rotary symmetrical manner. The concave/convex rotor blades rotate around a vertical arranged axis. Rotor blades rotate in a winding direction, when a concave side of the rotor blades faces a wind direction. The rotor blades rotate against the wind, when a convex side of the rotor blades faces the wind direction. Three satellite-air guiding plates (10) are fixed in a rotation symmetrical manner in a central point of a rotatable supported rotor axis (7). The rotor blades are made of non-rusting material.
