As the ebb and flow of the water during tidal action cause the displacement vessel to drift in a second lateral direction, the second anchor cable is unwound from the second drum causing the second drum to rotate as the first anchor cable is reeled back into the first drum by a control mechanism as described above.

The specified length that the guide mechanism travels may be a function of the diameter of the anchor cable 213. After the guide mechanism has traveled one full length of the drum 213, the guide mechanism may switch its direction of travel and move in a second direction that is opposite the first direction. Alternatively, the two drums may be operatively coupled such that the second cable may be automatically rewound on its drum as the cable on the first drum is unwound and thus be ready for unwinding as the displacement vessel moves in the other/opposite direction as shown in FIG. The control mechanism may controllably deploy the drag panel 121 at a specified time, such as a time when strong current conditions exist, to a second deployed position.

After the guide mechanism travels the length of the drum in the second direction, this process may be repeated. The gearing mechanism or alternatively, the gear box, may include a gear multiplication arrangement in order to increase the output RPM of the directional converter and applied to the generator. Generally, the directional converter may include a plurality of drums and a plurality of anchor cables to utilize the lateral motion in multiple directions to generate electricity. In addition, with suitable placement of anchored cables on generally opposite sides of the assembly, electrical power generation may be produced as the assembly moves in both directions (incoming and outgoing tides)-i.e., the cables can be mounted on different drums on the directional converter such that as one cable unwinds and operates the generator, the other cable is being re-wound for the next tidal cycle. FIGS. 1A-1C show a tidal energy conversion assembly 100 having a displacement vessel 102 that is buoyant at the surface 118 of the water and houses or supports a directional converter 109. Generally, the directional converter 109 is capable of capturing the drag-or “drift”-of the tidal energy conversion assembly caused by the ebb and flow of water due to tidal action.
Generally, the tidal energy conversion assembly may generate energy utilizing drift/drag forces from the ebb and flow of the tide and/or currents. One known tidal energy generation system utilizes large turbines placed in tidal streams in order to take advantage of the flow of water during tidal changes. These turbines are relatively expensive and may also require significant maintenance over their lifetime, thus increasing operating costs. Dolor en la vena de la pierna derecha . A tidal stream is a relatively fast-flowing body of water that is created by the rising and falling of the tide; the turbines are positioned to capture the horizontal flow of water and thereby generate electricity.
The gearing mechanism 214 is also coupled to an electrical power generator 216 such that rotation of the drum 213 is transferred to the electrical power generator 216 through the gearing mechanism 214 to generates electricity. The potential for generating electrical energy from the action of ocean phenomena generally comes in three sources: ocean thermal power, wave power, and tidal power. In another example described in more detail below, the displacement vessel may include redundant control cables (and, if desired, redundant control mechanisms) such that the displacement vessel may have eight control cables generally connected at the corners of the displacement vessel. Continuing the example from above, four control mechanisms may be mounted on the displacement vessel at each of the four connection points to independently control the four control cables.
