Disclosed herein is an array including at least ten wave power converters and at least one marine substation, each wave energy converter including a floating body, a wire, a housing anchored in a seabed or lakebed, the housing including a stator and a seesawing translator. The seesawing translator is connected via the wire to the floating body and each of the at least ten wave power converters is electrically connected to the marine substation. The at least ten wave energy converters are arranged on a symmetric, open, concave line, where a symmetry axis is at least more or less parallel to a primary wave direction and where the marine substation is arranged on the symmetry axis.

The present invention relates to a wind turbine blade (10) comprising a shell body with at least one pressure side shell member (36) and at least one suction side shell member (38), and a plurality of shear webs (70) arranged within the shell body. The plurality of shear webs (70) is successively arranged spanwise within the shell body such that adjacent shear webs overlap along part of their spanwise extent (L), wherein a gap (88) in the chordwise direction is provided between adjacent shear webs (70).

A wind turbine blade mould extending longitudinally in a spanwise direction and transversely in a chordwise direction is provided and a spar cap (134, 136) is laid the mould. The spar cap comprises a plurality of strips (138) extending longitudinally in the spanwise direction and arranged side-by-side in the chordwise direction, said strips comprising one or more intermediate strips (158) arranged between peripheral strips (160, 162) which are inclined relative to the intermediate strips. A shear web (126) comprising a flange (130a) extending longitudinally in the spanwise direction is provided, the flange comprising a base (144) defining a primary bonding surface (164). A chordwise width of the primary bonding surface corresponds substantially to a chordwise width of the intermediate strips of the spar cap. The primary bonding surface of the flange is bonded to the one or more intermediate strips of the spar cap.

A method for storage of excess energy which would otherwise be lost, the regulation of angular velocity, and prevention of excessive velocities is disclosed. The device consists of a bowl shaped container, divided into sections by radially oriented vertical walls, which holds a fluid (any appropriate liquid or set of small solid particles), and spins on its vertically oriented axis at various angular velocities. The floor of the device is formed in successive shapes of bowls and shelves, which allows for a kind of “gearing”. The invention allows more and more energy to be input into the device while the angular velocity is regulated within a particular range. A typical embodiment of the invention would include its attachment by a shaft at the axis to a vertical axis wind turbine.

Examples of a device for generating electrical power are provided, including a rotor element, a stator element and an electrical generator. The rotor element includes a rotor axis, and the rotor element configured for turning about said rotor axis responsive to an airflow being applied thereto. The stator element is configured for directing the airflow from an outside of the device towards said rotor element. The electrical generator is coupled to the rotor element and is configured for being driven by rotation of the rotor element about the rotor axis to thereby generate electrical power. The device is configured for being affixed with respect to a surface such that the device projects above the surface by an external maximum vertical dimension. The rotor axis is nominally orthogonal to the surface, at least in operation of the device. The external maximum vertical dimension is less than 1 meter.

A modular wind turbine system and a method of use thereof are provided. The system comprises: a mounting frame; a fixed toroidal support structure attached to the mounting frame, the toroidal support structure having a concave portion and a convex portion; a wind turbine located proximal to the concave portion of the toroidal support structure, wherein the wind turbine travels about at least a portion of the concave portion of the toroidal support structure; and a first baffle, wherein the first baffle extends about the portion of the concave portion of the toroidal support structure about which the first turbine travels, wherein the baffle surrounds a portion of the wind turbine opposite the fixed toroidal support structure, and wherein the baffle includes at least one component selectively variably adjustable so as to vary the force, direction, or disruption of flow of fluid thereby, relative to the wind turbine.

An energy conversion device is disclosed. Some embodiments include a mounting system for mounting the device in a fluid, an axle fixed to the mounting system, a hollow shell that rotates about the axle having axial symmetry about a longitudinal axis. The hollow shell may be substantially rounded at the front, expanding to a maximum diameter less than half the distance from the front end to the back end, and tapering radially along the longitudinal axis to the back end. The energy device may further comprise a plurality of blades on the exterior of the hollow shell, each blade extending from the front end of the hollow shell to the back end, rising to a maximum height, and having concave and convex walls. Other embodiments are described and claimed.

Disclosed is a blade shell section of a wind turbine blade, such as wind turbine blade with a flatback section. The blade shell section extends in a longitudinal direction from a first shell section position to a second shell section position. The blade shell section comprises a first laminate layer forming the outer surface of the blade shell section and a second laminate layer forming the inner surface of the blade shell section. The blade shell section further comprising a first shell section and a corner shell section between the contour shell section and the flatback shell section.
