The precise distribution of functionality preferably is made according to known engineering tradeoffs, with reference to the specific embodiment of the invention, as will be understood by those skilled in the art. Thus, although the present invention has been described in detail with regard to the exemplary embodiments thereof and accompanying drawings, it should be apparent to those skilled in the art that various adaptations and modifications of the present invention may be accomplished without departing from the spirit and the scope of the invention. The following embodiments address this problem. A more complete understanding of the invention can be obtained by referring to the claims and the following detailed description of the preferred embodiments in connection with the accompanying figures. The present system 450 is cost-effective and mobile, in that it can be quickly deployed or recovered to adapt to the changing tidal environment. FIG. 20 is a perspective view of an energy-generating system 450 according to a representative embodiment of the present invention.

For example, by diverting some of the water current away from one part of the paddlewheel (e.g., the top or the bottom) and toward the other part (e.g., the bottom or top, respectively), not only can that additional current be used to drive the motion of the paddlewheel, but less current is present to resist the movement of the paddlewheel when the paddles are moving in the direction opposite to that of the current flow. In the present embodiment, the paddles 476 are fixedly attached to the end structures 485 and 486. More preferably, one elongated member 480 is fixedly attached near the perimeter of each of end structures 485 and 486, and the other elongated member 481 is fixedly attached to the end structures 485 and 486 at points closer to the axle (or axis of rotation) 483 of paddlewheel 475, such that both of elongated members 480 and 481, together with and axis of rotation 483, lie at least approximately in the same plane.
As with the previously described dock embodiment, the present embodiment also is particularly suited for use in a stream or river, but also can be used in other environments. In the present embodiment, a single long paddle wheel 215 or, more preferably, two or four side-by-side paddle wheels 215 (e.g., as discussed above) are disposed along the length of structure 210. In addition, a front deck 217 slopes downwardly from the bottom edge of the dock 212 and directs the flow of the water current across the paddle wheel(s) 215. In addition, front deck 217 preferably houses an enclosure 220 that holds plastic foam or other buoyant material, so as to provide adequate positive flotation. FIGS. 28 and 29 then illustrate the situation when the current flow 629 is from the opposite direction (i.e., rear to front). FIG. 27 is a side sectional view of a portion of a paddlewheel having swinging or pivoting two-part rigid paddles, showing a single two-part paddle when moving in the opposite direction of the current flow, with the paddle surface area having pivoted so as to be approximately parallel to the direction of the current flow.

It is noted that in any of the foregoing structures, the paddles pivot from a power position in which they have the maximum surface area exposed to the water current to a hydrodynamic position in which they can move in the opposite direction of the relative current flow with reduced water resistance. FIG.

The main structure 102 includes a front portion 112 and a rear portion 113, each preferably comprising one or more ballast tanks 115 for controlling the overall buoyancy of the energy-generating unit 100, as well as for maintaining its proper orientation.
