Abstract: A two-body wave energy converter (WEC) that utilizes components in the two bodies having variable geometry is described. The WEC includes a surface control body which includes a first variable geometry component, and a reaction control body, which includes a second variable geometry component. During operating, the two variable geometry components may be substantially inflated to enable the WEC to generate electrical energy using power-take off (PTO) components or substantially deflated to allow for load shedding or protection from intense elements.

Abstract: A buoyancy motor is positioned within an interior volume of a vessel and submerged beneath a liquid level of a liquid that fills the vessel. The buoyancy motor includes an upper pulley, a lower pulley, and a belt extending around both the upper pulley and the lower pulley. A plurality of lift arms are hingedly coupled to the belt at a hinged mount. Each of the lift arms includes a connector arm, a float arm, and a float attached to the float arm. The float arms of the lift arms positioned on a first position of the belt are oriented perpendicularly with respect to the belt, and the float arms of the lift arms positioned on a second position of the belt are oriented parallel with respect to the belt. The buoyancy force of the liquid on the floats drives rotation of the belt around about the pulleys.

Abstract: A runner for a hydraulic turbine configured to reduce fish mortality. The runner includes a hub and a plurality of blades extending from the hub. Each blade includes a root connected to the hub and a tip opposite the root. Each blade further includes a leading edge opposite a trailing edge, and a ratio of a thickness of the leading edge to a diameter of the runner can range from about 0.06 to about 0.35. Further, each blade has a leading edge that is curved relative to a radial axis of the runner.

Abstract: A system in a water body uses buoyant force of gaseous Hydrogen and Oxygen to generate electrical power with one or more turbines that includes power resulting from the buoyant force while transporting the Hydrogen or Oxygen to a higher elevation, without loss of electrons, for conversion to electricity at the higher elevation. Conversion of Hydrogen and Oxygen to water through a Hydrogen Fuel Cell or by burning at the higher elevation may generate additional steam power, hydropower, or purified water. Portable submersible modules may transport the system below or above the water to and from the base of a plumbing portion of the system. The amount of gaseous fuel energy available at the higher elevation is not detrimentally impacted by the generation of electricity by the turbine.

Abstract: A wave energy converter utilizes a flotation module that rises and falls with the passage of waves, a submerged tube containing a constriction which multiplies the speed of the water passing therethrough, a turbine (or other hydrokinetic apparatus) positioned so as to extract energy from the accelerated flow of water within and/or through the tube, and a submerged gas- or liquid-filled chamber housing one or more energy conversion components (e.g. generators, transformers, rectifiers, inverters). By providing a chamber in proximity to the turbine, generators can be placed in closer proximity to the turbine that turns them, and the shared shaft can be shorter than if the generators were placed in the buoy adjacent to the surface.

Abstract: A system and method for a for a wave energy converter device that is an axisymmetric point absorber which operates in a tension only condition over a large stroke that can operate in the given wave environment so as to eliminate the need for end stops in normal operation whereby the wave energy converter device has a floating hull with an interior Power Take Off (PTO) that uses an impedance control scheme for impedance matching with the wave environment in which it is deployed so as to maximize electrical power output as compared with a passively operating device of similar size.

Abstract: A floating mooring system for a single CycWEC applies counter forces and torques to keep a generator suitably stationary for power generation without requiring fixed attachments to the ocean floor or requiring a large frame interconnecting multiple CycWECs. The mooring system uses floats or floatation structure with differential ballasting to counter operating torque and drag plates to counter reactive forces. The floatation structures may be used to float the CycWEC for transport to a deployment location, where changing the overall ballasting of the floatation structures submerges the CycWEC to a desired depth and differential ballasting in the floatation structures counts expected operating torques.
