Abstract
A wind turbine engine comprising rotor blades disposed within an outer casing and a half-spherical head located in front of the rotor blades and blocking the inner 50% of the radius of the rotor blades, the casing and head creating an acceleration chamber wherein incoming wind is speeded up and redirected around the head, and the accelerated wind then rotates the wind turbine rotor blades to generate power.
