stator blade 3 2 has a vertical edge 3 4 which when facing the wind will redirect the air flow into two different air channels the outward surface 3 5 has a smooth convex curvature between the exterior point of the stator blade and the tangential point of the rotor circumference the inward surface 3 6 has a sinuous shape curvature convex near the external edge and concave in the vicinity of the rotor this sinuous shape curvature based on coanda effect will redirect the air inflow tangentially to the rotor the presented design with different inward and outward curvature shapes creates an air flow channel with a large inflow opening and a fairly narrow outflow opening the significant size difference between the inflow and the outflow openings will create a natural compression and a substantial air speed increase that translates into a steady rotation of the turbine even in low wind the tangential disposition of the stator blades around the rotor and their inward concave curvature in the vicinity of the rotor based again on coanda effect will create a natural enclosure which will keep the rotating air flow a longer period between the disks allowing extracting more of the wind energy increasing the turbine efficiency fig4 shows the assembled rotor with a plurality of horizontal disks 4 1 and a plurality of narrow vertical blades 4 2 disposed on the circumference of the disks bordered vertically by a bottom disk 4 3 and a top disk.
