The invention relates to the shaftless horizontal axis wind turbine for generating electricity from the flow of fluid. The major components of the shaftless horizontal axis wind turbine consist of a stator and a rotor. The major components of the stator consist of a set of copper coils installed along a circular circumference of the stator frame and electrically connected as the Star connection (3-phase) circuit. The major components of the rotor consist of at least a set of the turbine blade, roller, and magnet set. The turbine blade has optimized an obtuse angle (θ.sub.T) of the turbine blade holder and a rotation angle (θ.sub.R) between the turbine blade holder and turbine blade to create the open channel in the middle of the shaftless horizontal axis wind turbine, which is shaped like a nozzle without shaft at the center of horizontal axis wind turbine.

A sea wave generating device includes a floating base, a generating assembly, a driving assembly, and a guiding housing. The floating base includes a base body and a cover plate. The generating assembly is secured in the base body and includes a lower magnetic wheel and a power generator. The driving assembly includes an upper magnetic wheel and a blade wheel. The upper magnetic wheel and the lower magnetic wheel are attracted magnetically. The guiding housing is secured to the base body and rests on the cover plate. The guiding housing covers the blade wheel and the upper magnetic wheel. Thus, when the sea wave is introduced into the guiding housing, the seawater pushes the blade wheel which drives the upper magnetic wheel which drives the lower magnetic wheel which drives the power generator to generate an electric power.

This disclosure is directed to hydrodynamic electric generators, including their structural design, methods of deployment, anchoring systems, drive systems and control systems. The system can be scaled from ones that can be hand carried to large, stationary devices that can generate up to and greater than 20 kw in a current of 3 knots. In a stationary system, the device can be anchored to an underwater floor by an anchoring device supported by four adjustable legs. These legs can eliminate the need for extensive mooring lines, providing the device with a small footprint that is non-hazardous to marine animals or vegetation. Individual components, such as rotors, generators and other mechanical components can be modularly installed for easy removal and servicing without having to disturb the entire system.

An assembly includes a transformer tank that is arranged in a nacelle of a wind turbine, wherein the transformer tank is configured to be filled with a gas or a liquid to cool the active part of the transformer and the active part is enclosed by the transformer tank in a liquid-tight or gas-tight manner, such that use of the transformer tank as a reinforcement or a bracing of the steel construction of the nacelle with as little additional material expenditure as possible for the transformer is facilitated by integrating the transformer tank into the mechanical support structure of the nacelle such that the transformer tank forms a part of the mechanical support structure of the nacelle and by providing at least one bracing in the interior of the transformer tank, where bracing connects mutually opposing wall regions of the transformer tank.

A wind turbine generator nacelle (14) comprises a nacelle frame (44) having a first forward hub end and a second aft end. Dedicated transport fittings (46) are positioned at each of the ends of the nacelle frame (44). The fittings (46) are adapted to be engaged by transport frames (86) on first and second transport trailers (80) for supporting the nacelle frame (44) for transport by the trailers (80). A service platform (20) is mounted to the transport fittings (46) on the aft end of the nacelle frame (44) such that the service platform (20) is cantilevered off of the aft end of the nacelle frame (44).

The invention relates to a wind driven power plant comprising a nacelle having a nacelle cover and a helicopter hoisting platform, the nacelle further comprising a hatch extension and a hatch cover, the hatch extension being arranged between the nacelle cover and the hatch cover, wherein the hatch extension has a channel-like shape, wherein the hatch cover is mounted on top of the hatch extension, and wherein a the hatch extension provides a distance between the hatch cover and the nacelle cover.

A nacelle assembly for a wind turbine is connected to a wind turbine tower through a yaw system and includes a front region coupled to a rotor having a rotor hub and at least one rotor blade. The nacelle assembly includes a nacelle having a cover structure to house wind turbine components and an add-on wind flow deflector system that is coupled to an outside of the cover structure. The wind flow deflector system guides wind flowing to the nacelle for reducing a drag of the nacelle when a wind direction is misaligned with respect to the longitudinal wind direction in a yaw system failure event.

A system for generating electricity using wind power for an electric vehicle (EV). The system converts wind to electricity for charging the EV's primary batteries, or to provide supplemental electricity to other EV systems, such as heating and cooling. The system comprises an air intake that compresses air along a narrowing path to a turbine component. The turbine component comprises a cylinder housing a turbine for capturing the compressed air. As the turbine rotates due to airflow, it engages at least one alternator to generate electricity. The at least one alternator is then connected to the EV's batteries or other vehicle systems for charging or immediate use.

For a refrigerant compressor, a flexible connection element that connects an end segment of a suction connection piece, which end segment protrudes into the interior of a housing, to a suction sound damper, in particular to a suction opening of the suction sound damper. The end segment itself thereby serves for fastening the flexible connection element onto the end segment and/or the inner wall of the housing.
