A fluid velocity actuated structure for a wind mill/water wheel, comprising an elongated cylinder with blades/fins hingedly supported thereon. When exposed to the driving force the one blade/fin will respond by assuming a position of least resistance thereto whereas the 180 DEG opposite blade/fin will assume a position of maximum resistance thereto. The hinge supports for the fins/blades has a swivel structure to permit resiliency in the cylinder to the fluid medium. From the rotating structure there is provided coupling means for converting the rotational force into electrical power. In use as a water wheel in a liquid stream, the cylinder has pump means associated there-with to adjust the depth of the structure in the fluid stream. When said structure is utilized as a wind mill, the cylinder is preferably upright and supported on a base. Within the base are a series of magnets that when electrically actuated, brakes the rotation of the cylinder. An electrical feedback system from the power source to the magnetic fields controls the magnetic force in a manner directly proportional to the wind velocity. Specific refinements and operational features are disclosed.
