  • Publication number: 20120086207
    Abstract: This invention is a device for transforming the energy of flowing water into useable energy. The device comprises one or more paddlewheels, and one or more generators mounted on a paddlewheel, one or more mooring lines, and a means by which to hold the device in position relative to the moving water. A subsea cable may be included to transmit the electrical energy generated by the device to shore.

  • Publication number: 20120087732
    Abstract: This invention is a greatly simplified device for transforming the energy of water waves into useable energy. The invention is a device for transforming the energy of water waves into useable energy comprising two or more buoys or buoys, and structural members connecting buoys, whereby motions of buoys relative to one another generates torque, and a means for transferring torque to one or more generators, and a means by which to enable all generator currents to flow in a single beneficial direction. Novel systems for interconnecting such devices are also described herein.

  • Publication number: 20120086210
    Abstract: This invention is a device for transforming the energy of moving air or moving water into useable energy. The device comprises one or more rope or rope storage drums, one or more ropes, one or more generators, and a means by which to receive the force generated by moving air or moving water such as a wing or sail. A gearbox or transmission may be added between drum and generator to increase the rotational speed of the generator. The device may be controlled via autopilot systems whereby the rope payout rates are optimized for maximum energy production.

  • Publication number: 20120086208
    Abstract: This invention is a device for transforming the energy of flowing water or air into useable energy. At a minimum, the device comprises one or more flow diversion structures, one or more paddlewheels, one or more generators and a means by which to control electrical load or otherwise control the rotational speed of one or more paddlewheels which improves the device's power output. A gearbox or transmission may be added to increase the rotational speed of the generators. A cable may be included to transmit the electrical energy from the device to other locations. Other elements may be added as described by the claims within this patent application.
