Resumen de: AU2019416124A1

A wind or water flow (hydrokinetic) turbine for harnessing a predetermined minimum or baseload value of renewable electric energy from the wind or water flow energy 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 three variable Hummingbird speed converter system, from a harnessed input power (input), the generated electric power (output) must exceed the electric power used for the control power (control input) and the input power must exceed the summation of control power and output power. Harnessed input power is provided to a power-balanced three variable mechanical gear control system when a control power of power versus load graph is crossed by an output power line graph to achieve an electrical advantage at a generator output. The three variable mechanical motion control system or "motionics" comprises a Hummingbird control assembly of first and second spur/helical/bevel/miter/ring gear assemblies or Transgear assemblies with an adjustment in between to eliminate variations from constant rotational speed input. The Hummingbird mechanical variable to constant speed control, a control motor and a generator among other components may be mounted on land or a floating platform. Constant electric power at constant frequency are delivered to a variable load.
