A system, method, and apparatus for generating hydroelectric power from subsurface wells penetrating or terminating in fluid-bearing, subterranean zones or intervals containing gas, oil, water, or any combination of these fluids. The system involves methods and apparatus summarized in a five-step process that includes: Phase 1—Fluid Production, Phase 2—Fluid Gathering and Combination, Phase 3—Hydropower Electricity Generation, Phase 4—Fluid Processing, and Phase 5—Fluid Pumping, Distribution, and Injection.

A hydro power generating system and device is configured to generate electrical power from the movement of water. The device consists of an elongated cylindrical hull to which comprises of a helical screw attached around the outer surface of a hull of the device. Movement of water over the screw causes the hull to rotate. The power created by the rotation of the hull is transferred to a generator located in the hull interior. The hull also contains water ballast tanks and a compressed air source in an air tank allowing adjusting the buoyancy of the device. The system is configured to couple adjacent devices in an array that can extend longitudinally, laterally and/or vertically via a common frame. At least a pair of counter-rotating screws is attached to a common frame, wherein the entire assembly of the system is anchored in flowing water.

A hydrokinetic turbine system for harvesting energy from riverine and tidal sources, including a first floating dock, a marine hydrokinetic turbine mounted on the first floating dock, and a second floating dock. The system further includes a winch assembly mounted on the second floating dock and operationally connected to the first floating dock and a linkage assembly operationally connected to the first floating dock and to the second floating dock. The linkage assembly may be actuated to pull the first floating dock into contact with the second floating dock. The linkage assembly may be actuated to distance the first floating dock from the second floating dock, and the winch assembly may be energized to orient the first floating dock into a position wherein the marine hydrokinetic turbine is above the first floating dock and wherein the winch assembly may be energized to orient the first floating dock into a position wherein the marine hydrokinetic turbine is below the first floating dock.

A tidal current energy converter including an infinitely variable transmission (IVT) control system and a hybrid vertical axis wind (or water) turbine (VAWTs) apparatus. The hybrid VAWT apparatus includes a modified-Savonius (MS) rotor in the central region and a straight bladed H-type Darrieus rotor in the surrounding annular region. The IVT control system includes a nonlinear closed-loop control combined with an integral time-delay feedback control to adjust a speed ratio of the IVT. A speed ratio control for an IVT system involves a forward speed controller and/or a crank length controller for different speed ranges. The time-delay control is designed to reduce speed fluctuations of the output speed of an IVT with an accurate speed ratio. The speed ratio of an IVT with the disclosed control strategy can achieve an excellent tracking response for the desired constant output speed and reduce speed fluctuations of the output speed of an IVT by the time-delay feedback control.

An enclosed hydroelectricity generator system includes an inlet channel, a low-pressure enclosed turbine, an outlet channel, and a hydroelectric generator. The enclosed turbine includes an inner can, an outer housing, a turbine axle, a plurality of paddle boards, and a water pressure containment chamber. The turbine axle is concentrically and symmetrically connected to the inner can. The plurality of paddle boards is radially connected around the inner can. The inner can and the plurality of paddle boards are rotatably enclosed within the outer housing. The inlet channel and the outlet channel are oppositely traversing into the outer housing. The inlet channel is in fluid communication with the outer channel through the water pressure containment chamber. The hydroelectric generator is operatively coupled with the turbine axle so that a kinetic energy of a pressurized water flow that enters into the water pressure containment chamber can be converted into hydroelectricity.

Disclosed is a water turbine including an endless chain with buckets and two floats disposed on either side of the chain, the chain driving electricity generators.

A piezoelectric power apparatus wherein piezoelectric material forms one wall of a liquid-filled container. Water pressure within the container is made to rapidly vary either by a cam operated piston or a motor operated ball valve acting on a pressurized liquid flow. The piston reciprocates through a wall of the container to alternately increase and decrease the pressure in the liquid. The ball valve periodically interrupts the pressurized liquid flow to alternately increase and decrease the pressure in the liquid. In either case, the alternate increase and decrease in the pressure in the liquid creates pressure variations in the piezoelectric material.

Mechanical movement exerted upon or over roadways is transmitted and converted to mechanical movement conducive towards the production of electrical energy. In one disclosed system, ramped or angled push bars are disposed within a roadway, such that a front set of bars and back set of bars will not be moved simultaneously. A series of one way values may enable subterranean fluid chambers to move a pendulum flywheel or rotor in a continuous direction or in a back and forth movement.
