An improved turbine over the old horizontal and vertical axis turbines because of its ability to capture several times the amount of wind. The basic design and process of this new machine can also work in the ocean at capturing ocean currents. Being Omni-directional (not having to turn into the wind) gives it one efficiency over the 3 bladed turbine. Another efficiency all embodiments have is its frictionless exponent. This quality helps save on wear and tear and maintenance cost. Most if not all past turbines have a static presents, being built in one basic wind capturing position. This new turbine is more dynamic because it can hide from wind damage and then open to capture more wind than its predecessors.

An energy system including a turbine wheel totally submerge including a rotary element and a wheel mounting enclosure. The wheel mounting enclosure including a cavity where a rotary element rest on said mounting enclosure exposing the upper end to the flowing body of fluid it is submerged. The wheel mounting enclosure comprising several configurations such as a tapered base for increasing the incident flow velocity.

The disclosed invention is a description of the means to create increased mechanical advantage by taking advantage of the rotation of confined liquid matter. The process described uses liquid both as a mass to store rotational energy, and at the same time the rotating liquid is used as a motive force to drive a rotating shell. A description of the process and one possible embodiment are presented.

A wave energy extraction device (or paddle) for converting wave energy into mechanical motion is curved in the horizontal plane, with a concave side (11) facing the incoming waves to increase energy capture and a convex side (12) on the lee side to reduce energy dissipation. The concave surface is substantially parabolic or semi-elliptical and the convex side is optionally provided with a substantially Gaussian profile (4) to improve the hydrodynamics and provide additional strength. To simplify connection to a base platform the paddle curvature optionally tapers to a straight edge (1) at the mounting points and the base device can be located either above or below the water surface. One embodiment is also curved about a vertical as well as the horizontal plane to create a spoon- or cup-shaped paddle (9).

According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.

A vertical twin rotor water turbine apparatus and method for extracting energy from a flow of water is described herein. The described apparatus delivers favorable performance by virtue the operation of a novel configuration of a plurality of central cores with at least one blade member extending from each core and flow directors to increase the effectiveness and efficiency of said device.

Systems, methods, and apparatuses are provided for generating clean energy. A Savonius vertical-axis wind turbine, including a shaft configured to rotate about a first axis, aerofoil blades transversely mounted with respect to the first axis, on the shaft, transversely extending outwards from the shaft to a first distance from the shaft, a generator coupled to the shaft, the generator configured to generate electricity from rotational energy of the shaft when the shaft rotates about the axis; and a first curved wind shield having a semi-circular shape defined by a curvature, each point of the curvature is a fixed second transverse distance from the shaft, the first curved wind shield positioned at the fixed second transverse distance from the rotating shaft, and the curved wind shield is rotatable about the rotating shaft, at the fixed second distance. In some embodiments, the wind shields increase productive wind circulation to the turbine blades.

The present invention relates to the field of energy generation. More specifically, it concerns a capture device and method which replaces and improves upon blades typically used for harnessing wind or water for power generation. The capture device is capable of efficient operation in a range of environmental conditions.

An automatic height adjusting paddle wheel comprising a housing, where the housing includes a pair of side portions; a paddle wheel positioned along a shaft within the housing; a pair of hoists attached to shaft on each side of the paddle wheel, where each hoists includes a cable coupled to a top portion of the housing; a means to detect a water level fastened to the cable within the hoists, where the means to detect the water level activates the hoists to lift the shaft as the water level raises and lowers in turn raising and lowering the paddle wheel; and a generator at each end of the shaft, where the generator produces electric power as the paddle wheel rotates within the water.

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.
