A river or tidal turbine for generating a minimum predetermined value of electricity from river current received at a harnessing module comprises a harnessing module, a control module and a generating module. Han's principle is that harnessed power from a river or tidal turbine must exceed a predetermined value of control power used by the turbine. Minimum power is lost in a three variable closed mechanical control system. The three variable closed mechanical system comprises a Hummingbird control assembly of first and second spur/helical gear assemblies which may be preferably mechanically simplified. The Hummingbird control, a control motor and a generator among other components may be mounted on a floating platform for delivery of constant power at constant frequency given sufficient input from a waterwheel harnessing module driven by river current flow in at least one direction. A tidal embodiment may comprise a moveable hatch for permitting the waterwheel to turn in foe same rotational direction regardless of direction of water current flow.

A marine hydrokinetic electric power or wind power generator may have three modules: a harnessing module, a controlling module, and a generating module. The harnessing module may have one of a propeller and a waterwheel for receiving wind or water energy. The controlling module may have a gearbox comprising gears for matching the expected wind or water generating power to an output power, a control motor, and a three variable gear assembly. The three variables are a variable input, a constant output and a constant speed control motor input variable. The variable input is received from the harnessing module and the constant output is delivered to an electricity generator. A generating module (generator) generates output power which may be a multiple of ten times the power rating of the controlling module (the constant speed control motor).

A harnessing module for harnessing renewable wind and water energy has opposing concentric wings for rotation about a turbine shaft having a hub having a wing support shaft for supporting each wing of 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 or a curved leading edge for facing one of air and water flow. Hence, the opposing concentric wings rotate about the turbine shaft in-line with a horizontal flow of air or water such that the turbine shaft faces a flow direction of the air or water and forms a harnessing module for generating electricity from either the wind or water flow.

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.

A marine hydrokinetic electric power or wind power generator comprises a harnessing module, a controlling module, and a generating module, the harnessing module comprising one of a propeller and a waterwheel for receiving wind or water energy, the controlling module further comprising a magnetic gearbox for matching the expected wind or water generating power to an output power, a control motor, and a Hummingbird comprising first and second Transgears and simplifications and variations thereof has three variables, input, output and control and connects the three modules. The assembly of harnessing module, controlling module and the generating module comprises an input shaft from the harnessing module and a constant speed control motor which may be an alternating current or direct current control input and a generator for generating power output and works like a rotary frequency converter: the rotational speed (rpm) of the control input dictates the frequency to be generated. The generating module (generator) generates output power which comprises a multiple of at least ten times the power rating of the controlling module (the constant speed control motor). Principles of application of a Hummingbird comprising first and second Transgears in conjunction with those of a rotary frequency converter, and simplifications thereof, may be extended to infinitely variable transmissions for gasoline and electric vehicles and to pumps and compressors.

Three controls, three variable gear assemblies, an optional hatch or variable propeller pitch, and a variable overlap generator (VO generator), as well as one or more commutator and brush-less free direct current generators may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed in a plurality of embodiments useful in wind power generation and water renewable energy generators for any of tidal and ocean current or wave conditions. Two Transgear assemblies side-by-side and sharing the same central shaft may comprise a constant speed motor control, produce required constant frequency and voltage and be reduced in part count and complexity. The variable overlap generator of a marine hydrokinetic or wind power generator may be used as a low torque generator, a high power-rated generator or a control in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range. An electromotive force (EMF) embodiment generates alternating current at constant frequency and voltage in varying wind and water speed conditions.
