  • Publication number: 20200191120
    Abstract: A harnessing module for harnessing renewable wind and water energy comprises opposing concentric wings for rotation about a shaft having a hub comprising at least one pair of opposing concentric wings for use in generating renewable electrical energy. Each concentric wing of the opposing concentric wings may have a circular leading edge for facing one of air and water flow, each concentric wing having a generally curved upper surface but for a curved downward surface and a sharp trailing edge opposite the circular leading edge of each concentric wing. The circular side and curved upper surface are preferably at a positive angle of attack where one of water or wind flow is received at the circular side and provides lifting rotation of the opposing concentric wings. Hence, the opposing concentric wings rotate about the turbine shaft and comprise a harnessing module for generating electricity from either the wind or water flow.

  • Patent number: 10670116
    Abstract: Three variable gear assemblies called Transgears, an electro-mechanical rotary frequency converter, and a variable overlap generator (VOG), may be used independently and together to provide constant frequency and voltage output power from variable input water flow and wind speed. Two sets of three variable spur/helical gear assemblies of sun and planetary gear sets are combined in a mechanical three variable control to form an assembly called a Hummingbird. A Hummingbird control may comprise a constant speed control motor and a constant speed generator to produce required constant frequency and voltage. In order to provide a constant control input, a constant rotational speed can be produced by a control motor. Once a constant rotational speed is produced, a constant electric frequency and constant AC voltage can be produced by the variable output generator.

  • Publication number: 20200095974
    Abstract: A river turbine for harnessing a predetermined minimum or baseload value of hydrokinetic energy from river current received at a harnessing module comprises the harnessing module, a controlling module and a generating module. Han's principle is that, in a torque balanced speed converter Hummingbird system, the generated electric power (output) from a harnessed input power (input) must exceed the electric power used for the control motor (control). Harnessed power is provided to the power balanced three variable mechanical control system when a control power line graph is crossed by an output power line graph to achieve an electrical advantage. The three variable mechanical motion control system comprises a Hummingbird control assembly of first and second spur/helical/ring/bevel/miter/worm and pinion gear assemblies or Transgear assemblies.
