A root assembly of a wind turbine blade for a wind turbine is provided. Also provided is a wind turbine blade including the root assembly and a wind turbine including the wind turbine blade.

Disclosed herein is a method for determining the arrangement of wave energy converters in a wave power park in a seabed or lake area including the steps of: measuring wavelength and wave direction over a period of time, collecting all values measured for the wavelength and the wave direction in a matrix, statistically determining, from the matrix, a predominant wavelength and a predominant wave direction, and arranging an amount X of wave energy converters at regular intervals over a distance that corresponds to half of the length of the predominant wavelength or a multiple thereof, where the distance is measured in a direction at least more or less parallel to the predominant wave direction.

An apparatus attached to the underside of a barge, a boat, a ship, a buoyant marine structure, and/or the like may include a plurality of conduits. A configuration of the plurality of conduits may increase the velocity of water moving, for example, at a high velocity due to the buoyant force (upward force) under the barge, the boat, the ship, the buoyant marine structure, and/or the like. The water, due to the increased velocity, may cause a plurality of hydroelectric generators to produce a vast amount of electricity and/or power.

A sea wave energy converter system, including a plurality of pioneer devices each of which is mounted on individual towers installed at a seabed, wherein each of the pioneer device includes an assembly having a set of gears connected to at least one fly wheel, at least one paddle, and a generator, wherein each of the pioneer devices mounted on the individual towers are lined-up in a particular arrangement covering a length of a sea crest so that incoming kinetic forces of sea waves rotates seriatim the at least one paddle of each of the pioneer devices to rotate the generator through the set of gears to generate electricity individually by each of the pioneer devices and wherein the particular arrangement is one of a diagonal arrangement, a cross arrangement, and a ‘V’ shaped arrangement.

A root assembly of a wind turbine blade for a wind turbine is provided. Also provided is a wind turbine blade including the root assembly and a wind turbine including the wind turbine blade.

An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a rigid linkage. The translating structure is configured to translate relative to the fixed structure. The blocker door extends between a blocker door first end and a blocker door second end.

A fixation device for providing at least one fixation location at a wind turbine, the wind turbine including a wind turbine tower, a nacelle and a hub for a number of rotor blades. The fixation device includes at least one fixation arm configured for being arranged at the nacelle and/or the wind turbine tower, the at least one fixation arm being extendable. The at least one fixation arm in an inactive state, when arranged at the nacelle, is not extending essentially forward of the nacelle.

In one embodiment, a system includes a shipping container holding a frame, and a plurality of assemblies attached to a surface of the frame. Each assembly of the plurality of assemblies includes a generator and a turbine coupled to the generator. The generator is configured to generate electricity in response to rotation of the turbine. One or more walls of the shipping container are removable to remove the frame from within the shipping container.
