An apparatus for generating offshore wind employs shallow draft floats supporting a lattice tower with a wide base having a single-line anchoring providing passive yawing. The lattice structure supports a horizontal shaft at both ends of the shaft for rotating a rotor assembly. Mechanical energy from the rotor may be transferred to electrical generation equipment located at the base of the structure.

Energy harvesting system, for harvesting energy from renewable resources, including an array of wind turbines disposed along a towering construction, and plurality of laterally outlying ledges branching outwardly in vertically spaced-apart respective levels, alternately lined-up along the towering construction between the wind turbines. Each of ledges includes an upper ledge surface and/or a lower ledge surface, slanted at a slope for deflecting ingoing wind and/or diffusing outgoing wind toward and away from the adjacent wind turbine, respectively. A photovoltaic (PV) solar panel layout is disposed on upper ledge surface, and includes at least one PV solar panel for absorbing and converting solar energy into electricity. The system may include one or more energy storage modules, usually operational for being lifted along towering construction. The towering construction may include wind and solar sensors and may be rotatable, so as to adjust horizontal orientation of towering construction for optimal energy harvesting.

A node for a lower structure of an offshore wind power generator according to an embodiment of the present invention relates to a node for a lower structure of an offshore wind power generator, which is manufactured by a casting method, the node including a body part into which a main pipe is inserted, a support part which is formed to be branched from the body part at a predetermined angle with respect to a height direction and into which a branch pipe is inserted, and a reinforcement part that protrudes from the body part, forms a predetermined radius of curvature, and thus reinforces coupling between the body part and the support part.

A wind turbine, having a floating foundation (1), a support structure (2) and a generator (3). The generator (3) is an up-wind generator. The floating foundation (1) is assembled from tubular steel sections (5, 6, 7, 8) of uniform diameter, forming a frame with a mooring turret (4) at one corner. The support structure (2) hays at least two beams (11, 12) extending substantially transverse to the floating foundation (1). The beams are connected at a first end to a respective opposite side of said foundation frame and at a second end to said nacelle (17). The support structure (2) and the floating foundation (1) form a triangle with the nacelle (17) fixedly mounted at the apex. The support structure (2) comprises tensioned backstays (13, 14, 15, 16) supporting the beams (11, 12) and ensuring that they are substantially subjected to compression forces only.
