Abstract: A power-producing windmill is disclosed. A paddle assembly having a central axis is supported for rotation on a frame. Two spaced-apart lateral sides supports the central axis and forms a channel in which the paddle assembly rotates. A pivotal vane is connected on one end of the channel for regulating the amount of air entering the channel is operated such as to regulate the rotational speed of the paddle assembly. A unique paddle configuration is provided which provides first and second wind-capturing cavities for increasing the total energy conversion efficiency of the wind to electromotive energy.

Abstract: A vehicle compressed air energy converter has been developed for use along vehicular roadways, railways and airfield runways to collect wind pressure developed by the vehicles, trains and aircraft moving through the atmosphere and convert such air motion to other useful forms of energy. The converter is activated by the force of the compressed air movement entering the converter and pushing the retractable air fins of the converter in a circular motion. That circular motion is transferred to a central shaft set in bearings at either end of a housing. As the multiplicity of air fins held in place by hinges on a circular rotating base move within the converter housing, the fins move into a retracted posture so as to offer less air resistance as they circulate within the portion of the converter not subject to movement of air from the exterior of the housing.

Abstract: Apparatus and method for harnessing fluid energy from a fluid current and converting it into mechanical energy. The invention comprises a big wheel and a little wheel where the little wheel rotates about on axis parallel to but offset from an axis about which the big wheel rotates. The little wheel rotates within the big wheel. Flexible sails are fastened between masts of the big wheel and masts of the little wheel so that when the wheels rotate each sail is unfurled and extended during one phase of operation and said sail is folded upon itself during another phase of operation. When extended or stretched open, the sail derives power from the fluid current. When the sail is folded, it offers a reduced resistance to the fluid current into which said sail is moving.

Abstract: A windmill having a stator and a rotor. The rotor has the shape of a long convex blade having sharp edges and being symmetrical with respect to its longitudinal axis. The stator which surrounds and supports the rotor comprises a lower platform which acts as a base, an upper platform parallel to the lower platform and a set of vertical and also equally spaced vanes joining the two platforms. According to a first embodiment, each vane is formed of an outer stationary shutter joining the two platforms and of a movable inner shutter capable of pivoting about its longitudinal axis. In an other embodiment, the vanes are one-piece element and can pivot freely on posts of which the ends are secured to the two platforms. In either case, there is provided a control mechanism responsible for the angular orientation of the movable shutters or vanes.

Abstract: Wind power engine having a rotor (1) which is rotatable about a vertical axis and has at least three rotor blades (A, B, C) arranged substantially radially which subdivide the rotor (1) into equisized sectors. To improve the characteristics and the efficiency of the wind power engine the rotor blades (A, B, C) are vertically subdivided into several sub-blades (3, 4, 5) and between the sub-blades (3, 4, 5) vertical gaps (6) are arranged for the passage of air. In cross-section said sub-blades (3, 4, 5) are dish-shaped or trough-shaped, the end regions of the sub-blades being angles or bent oppositely to the direction of rotation of the rotor through about 30.degree..

Abstract: A wind-driven apparatus for the conversion of kenetic energy in the form of wind to rotational mechanical energy. This apparatus incorporates a funnel that directs wind against a collector causing it to rotate. To prevent any backpressure in the funnel or against the collector, the area immediately downstream of the collector is free of any obstacle or channeling devices. To also prevent any backpressure from developing, a series of blow-through panels form a part of the funnel which open upon the presence of high pressure--the greater the pressure, the greater the opening.

Abstract: An improved vertical axis wind turbine is disclosed. The wind turbine in accordance with one embodiment, does not include a support tower but instead includes a bearing support for mounting a torque tube rotatably connected to blades, the bearing support being secured to ground by a plurality of guy cables. The torque tube may comprise a plurality of tube sections including an intermediate bearing and additional guy cables for supporting the torque tube to the ground in a vertical orientation. In another embodiment of the present invention, control means are disclosed for independently controlling the pitch of respective wind turbine blades in response to relative wind direction.

Abstract: A wind-driven power generator comprises a substantially horizontal roof including upper and lower roof members each having a peripheral edge and a contoured pressure reducing surface. The roof members are disposed in a spaced-apart relationship with the pressure reducing surfaces facing each other and defining an air space therebetween. The distance between the pressure reducing surfaces varies from a maximum spacing at the peripheral edges of the roof members to a minimum spacing at an intermediate location of the roof members. The power generator further includes a vertical suction pipe having an upper end connected to the lower roof member in flow communication with the air space at the intermediate location of the lower roof member. The lower end of the suction pipe extends downwardly from the lower roof member. An impeller is disposed in the suction pipe at the lower end thereof and rotates when air flows horizontally through the air space.

Abstract: A vertical axis wind turbine includes a pair of wind deflectors for directing the wind current into the rotor assembly. The wind deflectors are connected to the wind turbine so that their positions are automatically adjusted as a function of wind velocity as well as wind direction to maximize efficiency. The wind deflectors automatically move to a position downwind of the rotor assembly during periods of unusually high wind velocity and actuate a rotational governor which increases the angular inertia of the turbine to limit the speed of the turbine shaft during such high wind conditions.
