A fixed magnet generator may have an output in the range of 1 kW to 1 MW or more (as a potentially practical embodiment, a 5-6 MW generator can be used), although one of skill in the art will recognize that any suitable generator may be used to convert the rising and falling of the tide and/or ebb and flow of the water due to tidal action into electrical power. As the drums 813 a-813 f rotate and are engaged, the drive gears 812 a-812 f may rotate and transfer mechanical power to the gear boxes 814 a-814 f The engaged gear boxes 814 a-814 f may convert input RPM from the drive gears 812 a-812 f to a different RPM output to be transmitted to generators 816 a-816 f The engaged gear boxes 814 a-814 f are coupled to the generators 816 a-816 f, which may be, for example, fixed magnet generators as described above.
4 and 5) of the theoretical power produced by a displacement vessel utilizing a directional converter having a drag energy converter as the water speed is varied between 4 knots and 12 knots. As the propeller blades of the turbine rotate, the drum 1713 a also rotates causing the anchor cable 1703 to be wound or unwound and thus transferring mechanical energy to the directional converter 1709. As stated above, the directional converter 1709 may be substantially similar to the directional converters described above and may include a drum 1713 b coupled to the anchor cable 1703 and an electric power generator 1716. As the anchor cable 1703 is wound by the turbine 1750, the drum 1713 b rotates and transfers mechanical energy to the electric power generator 1716, which converts the mechanical energy into electrical energy. As indicated above, drive cable 110 is attached at one end to connector 111, which is attached to anchor cables 103 a-103 c and 105 a and 105 b, and at its other end to drum 113. As the tide rises, causing the displacement vessel also to rise vertically, the movement of the drive cable 110 (as further discussed below) causes drum 113, and thus drive gear 112, to rotate in either a clockwise or counter-clockwise direction.

In another embodiment, the directional converter may include a plurality of drums and a plurality of cables to utilize lateral motion in multiple directions to generate electricity (to be further discussed below). FIG. 18 illustrates a tidal energy generation assembly including a turbine mounted within a drag panel and a directional converter. In another aspect of the invention, the displacement vessels described herein may be replaced with other suitable mechanisms for capturing the ebb and flow of water due to tidal action and/or other current flows. When the tide changes, tidal currents due to the ebb and flow of water during tidal action may drag the displacement vessel laterally with respect to an initial starting point (as well as rise or fall with the tide). This method to produce electricity from the lateral ebb and flow of water due to tidal action may include the steps of: allowing the tidal action to change a lateral distance between a body floating in the water and a stationary location below the body; converting the change in lateral 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.
For example, a first control mechanism 1020 a may wind up (or shorten) control cable 1028 a while a second control mechanism 1020 b releases (or lengthens) control cable 1028 b, thus rotating the displacement vessel 1002 in a clockwise direction and controllably adjusting the amount of drag force exerted on the drag panel 1021. The first control mechanism 1020 a and second control mechanism 1020 b may also rotate the displacement vessel 1002 in the opposite (counterclockwise) direction by the reverse operation, i.e., the first control mechanism 1020 a may release control cable 1028 a and the second control mechanism 1020 b may wind up control cable 1028 b. For example, by rotating the displacement vessel to an angle away from the direction of water flow, less drag force may be exerted on the drag panel (and the turbine) thus reducing the amount of electricity generated by the electrical power generator.

The directional converter may be substantially similar to the directional converters described herein and thus converts mechanical energy transferred from the anchor cable to the directional converter into electrical energy to be stored and/or consumed. FIGS. 5A-5C show a tidal energy conversion assembly having a directional converter comprising a drag energy converter. The tidal energy conversion assembly may comprise a bidirectional hydraulic winch for winding the anchor cable and returning the displacement vessel back to a position over the stationary location.

Preferably, the directional converter and generator may be located away from the displacement vessel. The second distance may be greater than the first distance, and the change in vertical distance may activate the directional converter. The tidal energy conversion assembly may be substantially similar to the tidal energy conversion assemblies as described above and illustrated in FIG. FIG. Dolor y crujido de rodilla . 1A shows a cross-section of a tidal energy conversion assembly 100, according to an illustrative implementation. The displacement vessel 1102 of FIG. After the displacement vessel has traveled a distance D−h, the displacement vessel will be submerged a distance h under the water surface. In this embodiment, by floating at or near the surface 118 of the water, the elevation or distance 119 a of the displacement vessel 102 relative to the stationary location changes as the tide rises and falls.
To effect rotation of the displacement vessel, a first control mechanism may wind or release a first control cable such that one side of the displacement vessel changes its distance relative to the anchor cable. The first compartment 1223 a may be configured to be waterproof and/or store equipment, such as a control mechanism 1220 configured to wind and/or release the control cable 1228 a. The displacement vessel may further include a depth control mechanism to allow the displacement vessel to controllably change its operating depth in the water, such that it may operate at a “safe” depth to avoid objects in the water such as keels, propellers, and rudders of boats or other devices located in the water.
One of skill in the art will recognize that stopping mechanisms 1135 a and 1135 b may be placed at any point along the drag panel to limit the motion of the arms 1138 a and 1138 b. The second compartment 1123 b may include a material to maintain the buoyancy of the displacement vessel 1102, such as a gas, for example, to increase the buoyancy of the floatation device 1160. One of skill in the art will recognize that both compartments 1123 a and 1123 b may be configured to store a material to maintain buoyancy and/or house equipment. In one embodiment, the electrical power generator 116 may be configured to convert the rotation in the first and second directions from the gearing mechanism 114 or drive gear 112 into electrical energy. The second directional converter 909 b may reel in any excess slack in the anchor cable 903 by using, for example, a control mechanism similar to that described above.
