The electrical power may be transmitted through the power cable 1804 to the stationary location, where it may be stored and/or distributed to a power grid. In another embodiment, the electrical power generator 116 may convert rotation in a first or second direction into electrical energy. As the tide changes again and the displacement vessel moves laterally in a (generally opposite) different direction with respect to the stationary location, any slack on the anchor cable may be wound back into the drum by any conventional mechanism, for example, by a motor or spring. To effect rotation of the displacement vessel 1102, a first control mechanism 1120 a may wind or release the control cable 1128 a either alone or while a second control mechanism 1120 b releases (or winds) the control cable 1128 b. Pressure within each chamber may be similar or different from one another, depending on the buoyant force required of the tidal energy conversion assembly 400. Furthermore, each of the chambers 423 a-423 h may include a respective wall thickness.
In another aspect of the invention, the displacement vessel 502 may include a drag panel 521 extending from one of the exterior surfaces of the displacement vessel 502. The drag panel 521 may enhance capture of tidal currents and/or allow for the additional capture of currents that occur deeper in the water, such as undertow. In yet another embodiment, the displacement vessel may include multiple drag panels extending into the water from the bottom surface of the displacement vessel.

In an optional arrangement, the displacement vessel 1902 may include a turbine 1950 extending into the water from the bottom surface of the displacement vessel 1902. The turbine 1950 may be a standard underwater turbine as is known in the art. The turbine may be coupled to a drum that is under water (or alternatively above water in the case that the turbine is floating at the surface of the water) via a coupling mechanism such as, for example, a chain or belt. From this proximal end, the distal portions of the anchor cable 903 (including the distal end of the anchor cable 903) may be submerged by being threaded through one or more connections, such as an anchor or pulley that is located under the water at, for example, the bay/ocean floor or a submerged platform. Causas del dolor de espalda baja . In the reverse direction, as the displacement vessel 102 falls vertically with the falling tide, an optional frame may be positioned above the displacement vessel 102 and may include an attachment mechanism, e.g., a cable, coupled to the directional converter 109 to capture the change in potential energy in the opposite direction due to the falling of the displacement vessel 102. The stationary frame is immobile with respect to the water movements, and, as the displacement vessel 102 falls vertically with the tide, the displacement vessel increases its distance from the frame, generating a pulling force upon the cable attached to the frame.
The displacement vessel may be anchored or tethered to the bay or ocean floor or land by at least one anchor cable which is operatively coupled to the directional converter for translating the vertical movement of the displacement vessel to rotational movement which can be used to operate a generator and produce electric power. Among other potential advantages, such controlled adjustability may help reduce unnecessary stress on the apparatus and prolong its useful life. Each control mechanism 1020 a and 1020 b may independently wind up and/or release its respective control cable to effect rotation of the displacement vessel in the water. Alternatively, the first control mechanism 1120 a may unwind/release control cable 1128 a while the second control mechanism 1120 b may wind up control cable 1128 b to change the displacement vessel 1102 orientation in the water and rotate the displacement vessel 1102 counterclockwise. However, because the second displacement vessel 2102 b is connected to the anchor cable 2103, the second displacement vessel 2102 b pulls the first displacement vessel 2102 a back to the directional converter 2109 (i.e., upstream) as the second displacement vessel 2102 b travels downstream.
The barge may further comprise a hydraulic power mechanism to provide power to any components of the directional converter which may require hydraulic power, such as, for example, a reverse motor or winch. For example, if the displacement vessel is rotated from an orientation that is perpendicular to the flow of water to an orientation that is at an acute angle relative to the perpendicular, less force from the flow of water may be exerted on the drag panel. For example, as the tide rises, the vertical distance 119 a between the displacement vessel 102 and the stationary location increases. Conversely, as the tide falls, the vertical distance 119 a between the displacement vessel 102 and the stationary location decreases. Locking the displacement vessel 102 at a point close to the stationary location can also generate large amounts of electricity in a short time-frame, rather than with the gradual rise and fall of the tide.
The tidal energy conversion assembly 100 includes a displacement vessel 102 that is attached to a plurality of anchor cables 103 a-103 c and anchor cables 105 a and 105 b connected to anchors 108 a-108 e on the stationary location 106. Each of the anchor cables 103 a-103 c has a first end (e.g., at latches 107 a-107 c), a second end (e.g., at connector 111), and a length in between the first end and the second end.

In general, the tidal energy conversion assembly comprises at least one anchor cable connecting a displacement vessel to a stationary location, and the anchor cable may be secured at the stationary location. The currents caused by the ebb and flow of tidal action generally vary in a sinusoidal pattern and thus the amount of electricity generated may also vary in a similar manner. For example, a hydraulic ram may open and close windows (or through-holes) in the drag panel to change the surface area on which the tidal currents interact. In one basic aspect of the present invention, the tidal energy conversion assembly utilizes the vertical rising/falling of the tides to generate electricity. 1A-1D and 6A. The displacement vessel 502 further includes an electric power generator for generating electricity from the drag and a wire 504 for outputting the electricity. Dolor y ardor de espalda alta . If the platform is connected to the bay/ocean floor by one or more anchor cables, the platform may further include one or more buoyancy chambers to provide buoyant forces that allow the platform to float above the bay/ocean floor.
