The Vertical Tilting Blade Turbine Windmill device is for capturing kinetic energy from the wind and is comprised of a vertical shaft having a central hub connectively attached, the central hub having a plurality of wind capture arms comprising a rotating wind capture blade having a capture surface and a slicing edge that are rotated wherein the wind capture blades are rotated between a blade mode to capture the wind and a knife mode to pass with less drag resistance through the air/wind thereby enabling an increase in the ability to capture more of the energy available in an on-coming wind stream.

In a vertical rotor apparatus that rotates in response to a moving fluid, a shaft defines an axis of rotor rotation. Rotor blades are longitudinally aligned in parallel with the shaft and each rotor blade defines an axis of blade rotation. A sensor generates a signal when any of the rotor blades are within rotor azimuthal angles of blade stall regions. A controller generates blade pitch information for the blade stall regions and an actuator, which is mechanically coupled to each of the rotor blades, alters blade pitch about the axis of blade rotation in accordance with the blade pitch information.
