A kinetic fluid energy to mechanical energy conversion system includes hubs that are rotatable with respect to a hub carrier and support one or more independently controlled articulating energy conversion plates (“ECP”) and a track orientation control mechanism (“TOCM”) for alternating the independent control of each ECP in response to operating conditions. Each ECP has opposed surfaces and leading and trailing edges and may have one or more lips projecting from one of the opposed surfaces, wherein the one or more lips comprise at least an inboard end lip extending transversely from an inboard end of the plate. Articulation of each ECP is controlled by a follower within a track that is rotatable with respect to the hub carrier, and service lines pass through a chase or bore passing through the hub carrier to bring power and/or control signals to the TOCM for effecting controlled, powered rotation of the track.

A kinetic fluid energy to mechanical energy conversion includes rotatable hubs supporting one or more independently controlled articulating energy conversion plates (“ECP”) and systems and components for alternating the independent control of each ECP in response to operating conditions thereby comprising an energy conversion regulation method. Separator plates for controlling fluid flow with respect to each ECP may be employed above and below the hub and may also be directionally altered in response to operating conditions and included within the energy conversion method.

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.
