    摘要： A wind turbine rotor comprising a hub (1) from which a plurality of blades (2) project to a radius of at least 50 metres. Each blade comprising a hollow fairing supported by a central spar. Each blade has a thickness t at a radius r; characterised in that when r=0.5 R, t>0.3 T, where R is the radius of the blade and T is the thickness of the blade at the root end. By being thicker for a greater proportion of the blade, the aerodynamic performance of this part of the blade is worse, but this is more than compensated for as it allows better aerodynamic performance where it matters more, namely at the outer part of the blade. It also allows larger blades to be provided.

    摘要： The invention concerns a wave energy plant with at least two floating bodies, where each floating body is made up of at least two pontoons, preferably cylindric pontoons with a length larger than the diameter, where the pontoons are rigidly connected by rigid members, where at least one energy absorbing mechanism is arranged between two interhinged floating bodies. By such a plant is achieved the advantage that the number of movable parts is minimised, and that a plant according to the invention thus becomes more easy and rapid to service. Also, there is achieved the advantage that even by small waves, the floating bodies farthest from the energy absorbing mechanism are provided a substantial movement with a substantial force, as the plant may be designed with a relatively long lever arm from the outermost pontoon and to the hinge between the two joined floating bodies at which the energy is absorbed and transformed.

    摘要： The invention relates to a spar cap for a rotor blade of a wind energy plant, having a longitudinal extension from a first end to a second end, a transverse extension orthogonal to the longitudinal extension and a thickness orthogonal to the longitudinal extension and the transverse extension. The invention further relates to a method for producing the aforementioned spar cap. The spar cap has a longitudinal extension from a first end to a second end, a transverse extension orthogonal to the longitudinal extension and a thickness orthogonal to the longitudinal extension and the transverse extension. The spar cap comprises at least two layers of a first fiber composite material and at least one layer of a second fiber composite material, the first fiber composite material having another matrix material and/or other fibers than the second fiber composite material, wherein the second fiber composite material is disposed in a portion adjacent to the second end in the direction of the thickness between the at least two layers of the first fiber composite material, the at least one layer of the second fiber composite material ending before the second end.
