Abstract

Claims (41)

1. A method for operating one or more water turbines for power generation comprising:

forming at least a portion of one or more walls to create an estuary, wherein the one or more walls include at least a first wall and a second wall, wherein at least the first wall is angulated relative to the second wall to funnel and magnify a flow of water into or out of the estuary as a result of a tide flowing along a flow channel;

positioning the one or more water turbines adjacent to an outlet to the estuary;

receiving the flow of the water as a result of the tide into the estuary;

retaining the water within the estuary; and

selectively releasing the water as an outflow from the estuary, wherein the outflow turns a rotor of the one or more water turbines.

2. The method of claim 1 , wherein at least one of the one or more water turbines are positioned adjacent or at an outlet from a reservoir that is a dam that communicates with and receives water from the estuary but is configured to hold the water separate from the estuary for selective use.

3. The method of claim 2 , wherein a level of the water within the reservoir is selectively raised or lowered by a drum.

4. The method of claim 3 , wherein the drum is filled during a high tide and is selectively drained to change the level of water within the reservoir.

5. The method of claim 1 , further comprising:

forming a second estuary that selectively communicates with the estuary, the second estuary is open to ocean and has a man modified floor configured to magnify a level of the water as result of the tide being received by the estuary.

6. The method of claim 5 , wherein the man-modified floor includes a ramp.

7. The method of claim 1 , further comprising:

adjusting a power split transmission coupling to transfer torque from the rotor to a generator by working a hydraulic fluid, wherein the generator converts mechanical power to electrical power;

diverting the hydraulic fluid at high pressure from the power split transmission coupling in response to the electrical power produced by the generator exceeding a threshold to maintain the electrical power produced by the generator at or below the threshold;

storing the hydraulic fluid diverted from the power split transmission coupling under high pressure in a storage vessel; and

introducing the hydraulic fluid stored at high pressure to a hydraulic motor in response to the generator producing below threshold electrical power, the hydraulic motor operatively coupled to the generator and configured to transmit mechanical power to the generator for electrical power generation.

8. The method of claim 1 , further comprising at least one of: wind turbines and wave power generators positioned in or adjacent the estuary.

9. The method of claim 1 , wherein selectively releasing the water includes passing the water through a venturi to the one or more water turbines.

10. A system for use in power generation using water as a result of a tide to an estuary, the system comprising:

a plurality of reservoirs communicating with the estuary, wherein the plurality of reservoirs are configured to receive the water as a result of the tide from the estuary, wherein one or more walls of the estuary are shaped by human activity including at least a first wall that is angulated relative to a second wall in order funnel and to magnify a level of a flow of the water as the result of the tide to the plurality of reservoirs; and

one or more water turbines positioned within or adjacent an outlet from one or more of the plurality of reservoirs, the one or more water turbines each having a turbine rotor configured to produce a rotor torque in response to an applied loading by outflow of the water from one or more of the plurality of reservoirs.

11. The system of claim 10 , further comprising:

a power split transmission coupling configured to transmit the rotor torque to an output shaft at an adjustable torque ratio and divert hydraulic fluid in response to the output shaft exceeding a threshold power;

a hydraulic fluid storage vessel configured to store the hydraulic fluid that is diverted under pressure;

a hydraulic motor including a motor output configured to receive the hydraulic fluid stored under pressure and generate a torque on the motor output in response; and

a generator operatively coupled to the output shaft and the motor output, wherein the generator produces electrical power in response to at least one of rotation of: the output shaft, the torque of the motor output, or both.

12. The system of claim 10 , wherein a level of the water within one or more of the plurality of reservoirs is selectively raised or lowered by displacement-cause caused by a drum that is selectively moveable.

13. The system of claim 12 , wherein the drum is filled during a high tide and is selectively drained to change the level of water within the one or more of the plurality of reservoirs.

14. The system of claim 10 , further comprising one or more wave power generators positioned adjacent to or on an ocean wall side of an obstruction.

15. A system for use in power generation using water as a result of a tide to an estuary, the system comprising:

a plurality of reservoirs communicating with the estuary, wherein the plurality of reservoirs are each partially formed by man-formed dams and partially formed by a naturally occurring land formation, wherein the plurality of reservoirs are configured to receive the water as a result of the tide from the estuary, wherein one or more walls of the estuary are shaped by human activity including at least a first wall that is angulated relative to a second wall in order funnel and to magnify a level of a flow of the water as the result of the tide to the plurality of reservoirs; and

one or more water turbines positioned within or adjacent a gate or channel from one or more of the plurality of reservoirs, the one or more water turbines each having a turbine rotor configured to produce a rotor torque in response to an applied loading by an inflow or outflow of the water from one or more of the plurality of reservoirs.

16. The system of claim 15 , wherein the estuary is at least partially man-formed having some of the one or more walls being one or more man-formed walls and having some of the one or more walls being at least partially formed by the naturally occurring land formation.

17. The system of claim 15 , further comprising:

a power split transmission coupling configured to transmit the rotor torque to an output shaft at an adjustable torque ratio and divert hydraulic fluid in response to the output shaft exceeding a threshold power;

a hydraulic fluid storage vessel configured to store the hydraulic fluid that is diverted under pressure;

a hydraulic motor including a motor output configured to receive the hydraulic fluid stored under pressure and generate a torque on the motor output in response; and

a generator operatively coupled to the output shaft and the motor output, wherein the generator produces electrical power in response to at least one of rotation of: the output shaft, the torque of the motor output, or both.
