  • Patent number: 7845899
    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.

  • Patent number: 7726933
    Abstract: A wind powered turbine engine comprising an internalized containment and control chamber, intake enhancement, vacuum induction exhaust port and horizontally rotating rotor The turbine functions similarly to a steam or gas turbine engine. The radius of the control chamber decreases progressively as it curves around the periphery of the turbine rotor in the manner of a spiral.

  • Patent number: 7726935
    Abstract: An horizontal axis wind turbine having a rotor (3) with a frontal projection comprising a stationary spherical head (1) upstream of its multibladed turbine rotor (3) displaces and increases the speed of wind addressed over 70% of the total frontal area. A series of thin airfoils (12) radially and evenly placed on said spherical head (1) to direct wind towards the turbine short blades (4).
