Abstract
A turbine responsive to a moving fluid, which can be wind or another fluid, wherein a rotatable central shaft supports at least one radial arm with a blade assembly at the free end of the radial arm. The blade assembly includes a rocking arm pivotted on the radial arm, a blade member attached to the rocking arm, or a part thereof, and a counterweight attached to the blade. The blade assembly articulates with respect to the radial arm in response to the interaction between the moving fluid and the blade. The turbine is self starting and self controlling in response to excessive moving fluid velocity.
