Abstract
A wind turbine with a vertical axis includes a base; a central shaft; and a rotor operationally engaging the central shaft. The rotor is rotatable relative the central shaft, and coaxial therewith about the vertical axis. The rotor includes a plurality of pairs of blades, each pair of blades including a larger outer blade and a smaller inner blade. The outer and inner blades define at least one diverting and distribution channel for a laminar flow effect induced by the inner blade against the outer blade, involving a delay in the detachment of the air flow from the edge of the surface of the outer blade, allowing the turbine to operate in wind having a speed about 2 m/s.
