Free wing turbine

Apparatus for generating electrical energy from kinetic energy inherent in movement of a fluid comprising:

• guide track means disposed to have a major extent of its length across the path of flow of the direction of prevailing fluid flow,
• at least one support assembly structure disposed for movement along said guide track means,
• an air-foil member rotatably mounted upright on said support assembly structure,
• guy wire means extending from an upper portion of said air-foil member to said support assembly structure to support said air-foil member upright thereon,
• said air-foil structure being adapted to rotate on said support structure to a position with respect to the direction of fluid flow over said air-foil to obtain an optimum angle of attack with respect to the movment of fluid across said air-flow member,
• thereby to move in a direction across the path of fluid movement thereby to move said support assembly structure therewith,
• wheel means associated with said support assembly structure and disposed for rolling movement along said guide track means,
• said guide track means and said wheel means being cooperatively engaged to counteract any forces acting on said air-foil and support assembly structure tending to capsize said air-foil and support assembly structure, and
• electrical energy generator means mounted on said support assembly structure,
• said electrical energy generator means being operatively coupled to said wheel means whereby rotation of said wheel means along said guide track responsive to movement of said support assembly structure along said guide track operates said electrical energy generator means to generate electrical energy.
