In other embodiments where tidal currents are stronger, a metal or polymer drag panel may be preferred. Such a displacement vessel 1102 that can be rotated in the water to change the amount of drag force exerted thereon may be configured to capture a larger amount of drag forces during peak electric usage times and capture a smaller amount of drag forces during non-peak electric usage times. The spring may store potential energy as its coils are compressed by the rotation of the drum 113 due to the unwinding of the anchor cable or drive cable from the drum 113. As the displacement vessel 102 falls with the tide, the coils of the spring may expand (from the forces stored in the compressed coils) causing the axle 115 to rotate in an opposite direction and produce rotational energy that is then transmitted to the electrical power generator for generating electric power during the falling tide.

The directional converter converts this force into mechanical energy (e.g., rotational energy), and that mechanical energy is transmitted to an electrical power generator for electricity generation. As the drum turns, thus causing the axle on which the drum is fixed to also turn, the chain will transfer rotational power directly to the axle of the fixed magnet generator, causing the permanent magnet to rotate and induce an electric current within the armature to produce electrical power for storage or consumption. Generally, the wall thicknesses of the displacement vessel of the present invention may be between 0.1 inch and 6 inches, but one of skill will understand that any suitable thickness may be used to withstand drag forces caused by the ebb and flow of tidal action or hydrostatic pressure. One of skill in the art will recognize that both sides 1421 a and 1421 b need not be the same.
As can be appreciated by one of skill in the art, the retractable drag panel as described above may increase the area of the side of the displacement vessel that experiences the drag forces, thus increasing the energy captured. The pressures within each chamber may be similar or different from one another, depending on the external static fluid pressure acting on the tidal energy conversion assembly 400. Furthermore, each of chambers 423 a-423 h may include a wall thickness that is substantially similar to one another or different, depending on the pressure desired for the individual chamber to accommodate for static fluid pressure at increasing depths.
In one aspect, a tidal energy conversion assembly of the invention captures energy from the rising and/or falling of the tide. In this embodiment, the directional converter 509 includes a drum 513 and control mechanism 520. FIG. In an embodiment, the arms 1138 a and 1138 b may be longer than length D1 such that the control cables 1128 a and 1128 b may extend away from either side of the drag panel 1121 and connect to the anchor cable 1103 without contacting the surfaces of drag panel 1121. Similarly, arm 1138 c may extend past length D2 such that anchor cable 1128 c may extend away from either side of the drag panel 1121 and connect to the anchor cable 1103 without contacting the surfaces of the drag panel 1121. This configuration may be particularly useful to prevent the control cables 1128 a-1128 c from contacting the drag panel 1121 during operation and/or causing frictional wear on the control cables 1128 a-1128 c.
The anchor may also comprise a pulley mechanism that may be used to reduce or minimize friction between the anchor cable and anchor as the displacement vessel rises and falls with the tide and/or drifts due to the ebb and flow of the water during tidal action. Dolor en la mitad de la espalda . For example, the displacement vessel 102 may be locked at a low point in a tidal cycle, where the displacement vessel 102 is close to the stationary location 106. The displacement vessel 102 may be released at a desired time when the tide is higher, e.g., at or close to high tide, thereby allowing the displacement vessel 102 to vertically rise a maximized distance from the stationary location 106 in a short period of time. For example, the gearing mechanism 114 may take a slower rotation of a larger gear and convert that input rotation into a faster output rotation of a smaller gear.

In an aspect of the invention, a displacement vessel may be coupled by one or more anchor cables to one or more directional converters positioned at a stationary location, such as land, for example. The directional converters are substantially similar to those described above and include drums 913 a and 913 b fixed to axles 915 a and 915 b which include drive gears 912 a and 912 b. Through central conduit 1213, the control cable 1228 may extend through arm 1238, be coupled to and stored in, a control mechanism housed within the displacement vessel 1202, such as in the floatation device 1260 a, for example, as described with reference to FIG.

In any case, the turbines may be anchored to or attached to the ocean/bay floor or may be floating at or near the water surface via a floatation device as described in more detail above. The floatation devices 1160 a and 1160 b may be similar to the floatation devices as described above with respect to FIG. As the displacement vessel rises with the tide, the force exerted on the directional converter will be constant over the distance that the displacement vessel rises to the water surface. In a particular embodiment, a method of the invention comprises the steps of: allowing the tidal action to change a vertical distance between a body at the water surface and a stationary location below the body, wherein the change in vertical distance is defined from a first distance above the stationary location to a second distance above the stationary location; converting the change in vertical distance of the body into mechanical energy; transmitting the mechanical energy to an electrical power generator; and generating electricity with the generator using the mechanical energy.

These chambers may be substantially similar to the chambers described below with respect to FIG. Except as set forth below in FIGS. In an embodiment, the buoyant force generated by the displacement vessel 702 may be approximately equal to the weight of the displacement vessel 702 such that the displacement vessel 702 remains buoyant at an elevation above the bay/ocean floor. The anchor cable may extend along the ocean/bay floor and be coupled to a directional converter that is stationed on land. 8 and 9, at a second end of the anchor cable 1103. As also described above, the directional converter may be operably coupled to a generator and both the directional converter and the generator may be located at a stationary location, such as land or a barge. The directional converter may include a control mechanism (for example, a spring or a motor) to reel the second anchor cable back around a second drum.

FIG. 19 illustrates a tidal energy generation assembly including a turbine directly mounted to the bottom of a displacement vessel. The drag panels may also include “windows” of any appropriate size within said drag panels that may be controllably opened or closed to adjust the desired drag force upon the displacement vessel. Eqn. 4 shows an equation for calculating force on a side displacement vessel due to drag, where FD is drag force, pf is density of the fluid, CD is coefficient of drag, and A is the under-water area of the displacement vessel, VW is the velocity of the water, and VB is the velocity of the displacement vessel.
FIG. 11C shows a bottom view of a displacement vessel during a rotation, according to the aspect described with respect to FIG. FIG. 23A shows a displacement vessel having a rotatable drag panel. Quitar dolor de espalda alta . 7, the displacement vessel 702 may itself be a drag panel (for example, without the displacement vessel frame shown in FIG. The control cables 2028 a and 2028 b may be further connected to an anchor cable and a directional converter similar to the embodiments described above. The generators 1616 a-1616 c may be engaged/disengaged in a manner similar to that described above with respect to FIG.

The displacement vessel may include a control mechanism such that the control mechanism may deploy and retract the drag panel from the displacement vessel. 11D may be rotated back to the state in FIG. In an example, as shown in FIG. Dolor en el hueso debajo de la rodilla . In an alternative embodiment of FIG. As the ebb and flow of water due to tidal action causes the displacement vessels 902 a and 902 b to drift in a second, different lateral direction away from the stationary location 906, the anchor cable 903 exerts a force on the second directional converter 909 b, causing the second directional converter 909 b to transmit mechanical power to the generator 916 to generate electrical power. The anchor may be constructed such that an anchor cable may be threaded therethrough or permit an anchor cable to be fixedly attached thereto. In another embodiment, at least part of the anchor cable 903 may be submerged under the water, such as at a desired operating depth of the displacement vessel, for example.
