An aerodynamic-hybrid, vertical-axis wind turbine which includes a rotor airfoil and stator blade combination which maximizes energy production by increasing wind velocity and pressure while eliminating back pressure and improving the laminar flow of wind both around and through the device. The rotor airfoils have a horizontal cross-section with a crescent shape including a convex leading side and a concave trailing side with a thicker middle section that tapers to narrower sections at ends. The stator blades have a horizontal cross-section with a planar side and a convex side. Rotor airfoil and stator blade combinations are secured between upper and lower annular sails.
