摘要： The device consists of a vertical axis (1), one or more bearing rings (2), rotor (3), one or more pairs of catchers (4) made of light and strong material, flexible connections (5) and valves (6) with air intakes (7). The device can be applied to capture mechanical pressure and extract energy from fluid flows. Since its catchers are made of flexible and light material, it is characterized by a simple structure, light weight, and easy production and repair. Also, the device has a large working area, and reduces to a negligible small value the aerodynamic resistance during the reversible half-turn of the rotor, which further increases its efficiency.

摘要： The application relates to unidirectional hydrokinetic turbines having an improved flow acceleration system that uses asymmetrical hydrofoil shapes on some or all of the key components of the turbine. These components that may be hydrofoil shaped include, e.g., the rotor blades (34), the center hub (36), the rotor blade shroud (38), the accelerator shroud (20), annular diffuser(s) (40), the wildlife and debris excluder (10, 18) and the tail rudder (60). The fabrication method designs various components to cooperate in optimizing the extraction of energy, while other components reduce or eliminate turbulence that could negatively affect other component(s).

摘要： A turbine apparatus (10) for deployment in a waterway, comprises a rotor support system (12), a rotor mechanism (14) and a power take-off device (16). The rotor support system (12) is operable to support and align the rotor mechanism (14) with a direction of flow of flowing water in the waterway. Deployment of the turbine apparatus (10) in flowing water generates power. The rotor support system (12) includes an elongated shaft (13), which includes a buoyancy adjusting component (17); a flexible coupling (15) at a first end; and the rotor mechanism (14) being attachable to a second free end of the elongated shaft (13). The flexible coupling (15) facilitates connection of the first end of the elongated shaft to a support structure and facilitates a substantially freely yawing connection of the axial flow turbine apparatus to a support structure located in the waterway in which the turbine apparatus is deployed. The flexible coupling (15) also controls pitching motion of the turbine apparatus (10) relative to the support structure; and in use, permits a predetermined range of yawing motion of the turbine apparatus relative to the support structure; and responds to changes in flow of the flowing water, to maintain the turbine apparatus (10) with a compliant attitude, thereby maintaining alignment of the axis of the elongated shaft and the rotor mechanism with the direction of flow. The buoyancy adjusting component (17) being operable to maintain the deployed turbine apparatus with substantially neutral buoyancy relative to the waterway in which the turbine apparatus is deployed.

摘要： A toroidal lift force engine is provided. Illustratively, the toroidal lift force engine operates in an enclosed environment without heat and/or expelling particles of any kind, utilizing asymmetric pressure distribution on lift turbine blades solely to generate thrust with the normal component of this lift force, while using the tangential component of this lift force to drive accessories, provide control to the fluid velocity, and/or provide motivation of the fluid's flow. The toroidal lift force engine may be utilized to generate thrust, heat and/or electricity for powering vehicles, homes, etc.

摘要： An accelerated and/or redirected flow arrangement, optimally serving as a wildlife and/or debris excluder (WDE), is used in combination with a turbine-like device having an inlet end and an outlet end for fluid flowing therethrough, e.g., a hydro-turbine. The arrangement includes at least a forward part designed to be placed in front of a fluid inlet of a turbine-like device and configured to produce at least one of the following effects on the fluid: (a) imparting a re-direction of the fluid; and/or (b) accelerating the flow velocity of the fluid, as it flows through the forward part. Turbine-like devices having both a forward part and a rearward part of flow arrangement are disclosed, as well as a method of enhancing turbine performance.

摘要： The present invention relates to a waterpower stream amplifier device primarily comprised of a body with an outer surface further comprised of at least one exterior protrusion and an interior surface further comprised of at least one angular flow director. The device can be placed/combined with the rotor of an underwater hydroelectric turbine in order to concentrate and multiple the energy of the water stream entering the turbine. The at least one angular flower director of the interior surface, the at least one exterior protrusions and at least one longitudinal opening of the outer surface allows water to enter the interior surface of the body from all directions. As a result, a rotating water vortex is created within the interior surface as the water travels from the first end towards the second end.
