Provided are a floating structure fluid dynamic force use system and a wind-propelled vessel which uses the system whereby it is possible to compensate for overturning moment due to fluid dynamic force and to alleviate both tilting and size increases of a floating structure. A floating structure fluid dynamic force use system (1) comprises an assembly (12) which extracts energy from wind or water, and a floating structure (13) which supports the assembly (12). The assembly (12) comprises a wind receiving part (10) which receives fluid dynamic force, and a support column (11) which supports the wind receiving part (10). The assembly (12) is positioned with the center of gravity (15) thereof below the water line and is supported to be capable of tilting in an arbitrary direction upon the floating structure (13).

A method of assembling a rotor lock assembly for use in a wind turbine. The wind turbine includes a rotor rotatably coupled to a generator by the rotor shaft. The generator and the rotor shaft are supported from a bedplate frame. The rotor shaft includes a rotor lock disk. The method includes coupling a support frame to the bedplate frame. The support frame is positioned adjacent to the rotor lock disk. A plurality of lock pin housings are coupled to the support frame. Each lock pin housing of the plurality of lock pin housings is positioned with respect to the rotor lock disk. A plurality of lock pins is provided. Each lock pin of the plurality of lock pins is configured to engage the rotor lock disk. Each lock pin is coupled between a corresponding lock pin housing of the plurality of lock pin housings and the rotor lock disk to facilitate limiting a rotation of the rotor shaft.

A propulsion drive system for boats that is operated by wind power is disclosed. Upon initial observation of a boat equipped with the invention, it looks like a conventional boat. However, after closer inspection, it can be seen that a mast located at the rear of the boat supports a windmill structure. The windmill operates in a horizontal manner, similar to that of an anemometer. The central drive shaft is routed down the mast where it terminates in a gear box which increases the revolutions per minute by a factor of approximately 20 to 1. The output of the gearbox, complete with a clutch, is then routed to a propellor on the rear of the boat which is then used in a conventional manner. The features of the invention provide all of the advantages of a wind-powered boat without any of the disadvantages.

The windsurf board comprise a revolving sail, reciprocating fins and single sided pedal. The revolving sail rotates a drum to drive the reciprocating fin. On the drum, there are multiple cycles of slot knotched on the drum. One revolution of revolving sail will induce multiple flip-flop reciprocating motion of the reciprocating fin. The single sided-pedal uses the reciprocating motion to drive the reciprocating fins to propagate forward.

There is provided a wind propulsion device for driving a transmission shaft connected through intermediate members with devices for force transmission. The wind propulsion device comprises a wind impeller having a plurality of wind wings which are concavely curved against the air stream. The wind wings are axially connected to a semisphere convexly curved against the air stream which is axially disposed with respect to said impeller. The semisphere guides the air stream impinging on the center of the impeller to the tips of the wings for efficient wind utilization.

A hull propulsion mechanism includes a ship body; a wind blade, which is set to the top of the ship body and has a plurality of sails for obtaining a rotating force from wind blade; a shaft, which sustains the wind blade and is a rolling axis as well for conveying the rotating force by the wind blade; a water pump, which is a power unit that circulates water by making use of a turning force from the shaft; and an engine, which obtains hull propulsion from screws that are rotated by a circulated water pressure from the water pump. With this configuration, the hull propulsion mechanism can obtain enough propulsive force without consuming fossil fuels.
