  • Patent number: 11125212
    Abstract: A wind power generation method capable of efficiently generating electricity while preventing a rotor from stalling. A generator (3) is connected to a vertical main shaft (5) of a rotor (2) via a clutch (9). The method comprising repeating the following steps: disconnecting the clutch when the rotor is rotating at or below a predetermined average wind speed, to idle the rotor, connecting the clutch for generating power by the generator when the rotor reaches a specific peripheral speed or rotational speed, again disconnecting the clutch when the rotor is rotating at or below the predetermined average wind speed to idle the rotor until the specific value of peripheral speed or rotational speed is reached, and again connecting the clutch for generating power by the generator once the rotor reaches the specific value.

  • Patent number: 10110003
    Abstract: A system with three distinct but integral aspects for an effective energy optimization solution is disclosed. First, the system comprises a Smart Energy Load Center (SELC) adjacent to an energy generation facility (e.g., a wind farm) to limit or to entirely eliminate energy losses in transit and to reduce transmission and distribution infrastructure costs, and to eliminate energy handling costs reflected in relatively higher retail energy rates, compared to lower wholesale energy rates. Second, the system comprises methods to split existing energy consuming gadgets/gizmos (e.g., personal computers—PCs) into two sets of parts and moves the bigger set of the parts to the SELC without compromising the original functionality of the gadgets/gizmos. Thirdly, the system utilizes the material reduction and increased design features and cost savings yielded by the economies of scale offered by PCs residing at the SELC (Remote PC Warehouse) and harnesses the residual energy contained in the digital information.

  • Patent number: 8109722
    Abstract: A turbine for use with a turbine generator, the turbine including at least one turbine blade for positioning in a flowpath, a hub mounting the at least one turbine blade, and a rotatable shaft in operational communication with the hub via a hinge assembly, an axis of the hub being independent of an axis of the shaft. The hinge assembly is disposed between the shaft and the hub and configured to adjust an angle therebetween. A controller assembly is configured to adjust at least one operational characteristic of the hinge assembly during turbine operation. In one embodiment the operational characteristic is a teeter angle of the hinge assembly. In one embodiment operational characteristic is a stiffness or damping force. Methods for using and controlling a fluid turbine are also disclosed.

  • Patent number: 8057158
    Abstract: The invention relates to a wind turbine and a method for operating the wind turbine planted in the floor of a body of water. The wind turbine includes a support structure and a rotor, which is arranged on the support structure. The rotor has a rotor blade. The wind turbine operates in a trundle mode in order to reduce the oscillations in the support structure created through mechanical impacts on the support structure.

  • Patent number: 5436508
    Abstract: A wind-powered energy production and storing system comprises a wind rotor (1) in driving engagement with a power generator via transmission means, to which is also connected a heat pump for operation of at least one heat exchanger unit. The wind rotor (1) is designed as a wind wheel having a rim in direct driving engagement with a main shaft positioned in a subjacent engine housing (3) to which main shaft, in addition to the power generator and the heat pump, a dual circulation pump is coupled for conveying heated and cooled liquid, from a heating container and a cooling container, respectively, positioned in the engine housing (3) to separate heat and cold storing stations (16, 18). Via a steam separator (21) and a pumping device (22), a steam generator (17) may be connected to the heat storing station (16), which via a steam turbine (19) drives an additional power generator (20) for power production during periods of slack winds.

  • Patent number: 5195871
    Abstract: A windmill includes a plurality of fan blade units pivotally mounted in a central vertical transmission shaft each unit having a right-leaf vertical fan blade and a left-leaf horizontal fan blade in which the vertical fan blade as rotated to the leeward can be feathered by a forward rotation of a driving motor to reduce its wind resistance during its leftward rotation towards the windward, and the horizontal fan blade when rotated to the windward can be vertically erected ready for receiving wind energy by a reverse rotation of the motor during its righward rotation towards the leeward for efficiently collecting the wind energy for driving the transmission shaft for power generation.

  • Patent number: 4787819
    Abstract: A windmill device is provided having a windmill tail pivotally attached to a rear end of the fan or rotor assembly, to swing upwardly from alignment therewith, a laterally extending arm attached to the fan assembly to pivot therewith, and a depending flap vane hingedly attached at the top to a portion of the arm outside the wake thereof and urged to tilt forwardly in a downward direction towards the wind. The flap vane gradually swings the fan assembly away from pointing into the wind as the wind speed increases until a predetermined wind speed is reached when the fan assembly is held out of the wind with the arm extending parallel with the tail. A rear vane may be provided attached to the flap vane and forming an inverted V-shape therewith. An intermediate vane may also be provided extending downwardly between the flap vane and the rear vane.
