A system for generating energy from a water current flowing in a body of water. For example, the system may have a generator assembly operable to generate energy in response to the flow of the current and an anchor assembly located at the bed of the body of water, where the generator assembly is attached to the anchor assembly, is held between the bed and the surface of the body of water, and is rotatable about a substantially vertical axis with respect to the anchor assembly. For another example, the generator assembly may include a housing that is held in an upstream orientation when in use, and an impellor assembly located within the housing and including a plurality of blades arranged to be contacted by the flow of the water when in use.

A wind turbine blade device includes a rotating unit including a blade module concentrically connected to a rotating shaft thereof and having a plurality of radially curved channels each having inlet and outlet ends. The inlet and outlet ends of the radially curved channels are configured to respectively permit flow of the flow body into and out thereof. An outer tube includes a tube body surrounding the rotating unit, and a plurality of rib plates provided in the tube body. The outlet end of each radially curved channel corresponds to one of the rib plates, and each radially curved channel forms an included angle with a corresponding rib plate such that the flow body flowing out of the outlet end can impact upon the corresponding rib plate.

The mutually supporting hydropower systems includes a first hydropower system, a second hydropower system, and a third hydropower system. Each hydropower system includes a hydropower unit, a number of waterwheels, a number of hoist devices, and a number of motors respectively connected to the hoist devices. Each waterwheel engages a hoist device. The motors are electrically connected to a hydropower unit. The waterwheels and the hoist devices are driven by the impact of seawater which is also used by each hydropower unit to produce electricity. 40% of the power from the first hydropower system is used to drive its motors. 30% of the power from the second and third hydropower systems are also used to drive the motors of the first hydropower system. The motors are therefore sufficiently powered to discharge seawater.

A turbine assembly for a generator including a rotor that is operable to rotate about an axis; and a thrust absorbing member, wherein fluid is operable to enter the turbine assembly generally axially with regard to the axis of rotation of the rotor and to exit the turbine generally radially with regard to the axis of rotation of the rotor. The fluid is operable to contact the thrust absorbing member prior to contacting the rotor.

A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.

A mobile electric generating system for charging vehicle batteries, providing mobile refrigeration units, and/or charge lift gates or electric pallet trucks may be wind powered. The mobile electric generating system may include a fan assembly, a fan bushing, a fan shaft, a fan locking collar, a flinger collar, a bearing, a driver bushing, a driver sheave, a motor or generator, and a motor mount. The fan assembly is connected to the generator. Wind turns or rotates the fan assembly which rotates the generator creating electricity.

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).

A morphing panel mechanism may include a central panel and a side panel, where a first edge of the side panel may be pivotally coupled to a first edge of the central panel. A morphing panel mechanism may further include a guide panel that may be coupled with a first corner of the central panel via a ball joint, where the guide panel may include a first slit. A morphing panel mechanism may further include a flexible panel, where a first edge of the flexible panel may be pivotally coupled with a second edge of the side panel, and a second edge of the flexible panel may be slidably disposed within the slit of the guide panel.

The present invention relates to wind energy and can be used to harvest and convert kinetic wind energy into electricity with higher efficiency.

Wind turbine that improves the efficiency of converting wind energy into electrical energy by implementing mechanical design features which harness the entrainment effect by using main rotor blades that are mounted at some distance from the center axis of rotation to allow airflow to pass through its center and to be accelerated by any means (jet fan for example), thus creating higher velocity lower pressure air stream (according to Bernoulli’s law) behind the wind turbine increasing airflow (entrainment effect) through the main rotor blades.

The invention as claimed is a lift-based horizontal-axis wind turbine, the design of which provides higher performance efficiency by extracting more energy from the airflow and at better coefficient of performance and converting it into electrical energy, compared to conventional lift-based horizontal-axis wind turbines of the same turbine rotor diameter.
