  • Patent number: 11905919
    Abstract: Disclosed herein is a power generating apparatus for extracting energy from flowing water. The apparatus comprises a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel which comprises a turbine rotor mounted to a nacelle, and a support structure. The turbine assembly is pivotally moveable between a first position and a second position. When the power generating apparatus is floating on a body of water, in the first position the nacelle is fully submerged below the water surface; and in the second position at least a part of the nacelle projects above the water surface. Movement of the turbine assembly from the first position to the second position is buoyancy assisted, for example by providing the turbine assembly with positive buoyancy or selectively increasing its buoyancy.

  • Patent number: 11898543
    Abstract: A high performance hybrid turbine is provided which has an impeller towards which a fluid flow of water, air, or other fluid is conveyed for rotation of the impeller around an axis of rotation. The impeller exploits the thrusts that the fluid flow exerts on the elements constituting the impeller and the thrusts generated by a certain number of airfoils provided inside the elements of the impeller. The high performance hybrid turbine, if used as a wind turbine, can operate at much higher wind speeds than conventional wind turbines.

  • Patent number: 11846304
    Abstract: A high pressure engine propulsion system, such as a rocket engine, having improved engine performance is described herein. A liquid propellant, such as liquid oxygen, is paramagnetic. Cavitation bubbles of the liquid propellant can form in an inducer tunnel of a turbopump when the pressure in the turbopump inlet drops below the vapor pressure of the liquid propellant. The turbopump includes a magnetic field source external to the inducer tunnel to generate or provide a steady magnetic field across or through the inducer tunnel. The steady magnetic field interacts with the paramagnetic propellant, thereby reducing or eliminating cavitation bubble growth, causing cavitation bubbles to collapse, retaining cavitation bubbles within the inducer tunnel, the like, or combinations thereof.
