One example of an energy-generating unit 860 having an alternately configured housing is shown in FIG. 13, a tugboat 335 tows both anchor 320 and energy-generating unit 300. As shown in FIG. FIG. 14 is a left side elevational view illustrating deployment of an energy-generating unit and corresponding anchor. FIG. Dolor lateral de rodilla al correr . 10 is a left side center sectional view of an energy-generating unit that is particularly adapted for use in deep ocean currents. It is noted that due to the locations of the anchor positions 665A-D (i.e., a distance opposite the direction of rotation and closer toward the axle 483 of the paddlewheel 650 than the point of attachment of the corresponding pivotally attached elongated member 662A-D), the individual paddles 660A-D naturally form into appropriate shapes at each position along their rotation around the paddlewheel 650. Thus, for example, with reference to FIG.

At the same time, the rear face 22 of each baffle 16 (i.e., the face adjacent to the front of the paddle wheel 30 immediately behind it) preferably closely conforms to the paddle wheel 30 immediately behind it, thereby protecting such paddle wheel 30, e.g., from the force of the oncoming wave.

12, the paddles 330 of paddle wheel 305 preferably have a hook-shaped cross-section, i.e., curved at their distal ends and substantially planar at their proximal ends, with the curve having a concave face in the direction of the incoming water current. In the presently illustrated embodiment, the paddle wheels 105 have a diameter of approximately 15 feet. In addition, the side walls 14 can help to channel the waves over the paddle wheels 30. It is further noted that the present configuration of the entire main structure 12 (which includes the baffles 16, front deck 45 and side walls 14) also channels the spent wave returning flow under the energy-generating unit 10, in order to collect that energy as well, thereby further increasing efficiency. The present disclosure presents multiple different embodiments.

In the present embodiment, and air hose 350 connects energy-generating unit 300 to a surface buoy 352 for the purpose of re-floating energy-generating unit 300 when desired. However, functionality generally may be redistributed as desired among any different modules or components, in some cases completely obviating the need for a particular component or module and/or requiring the addition of new components or modules.

Sheet 478 preferably is loosely suspended between the elongated members (e.g., rods) 480 and 481, meaning that sheet 478 has a significant amount of slack, allowing it to form into different shapes. BACKGROUND There are a variety of different conventional systems for generating energy from water current. 31, the water current flow 680 is from front to rear, and the shape of the main structure of energy-generating unit 675 directs the current flow 680 primarily across the top of the paddlewheel 650. In particular, a lower portion of the structure has an upwardly sloping upper surface 682 and a downwardly sloping lower surface 683 (both, in reference to the horizontal plane and movement toward the paddlewheel 650), so that the structure becomes thinner as it extends further forward of the paddlewheel.

Alternatively, in certain embodiments enclosure 220 houses a ballast tank that is used to control the proper amount of flotation for structure 210. Although not shown in the attached drawings, a similar buoyant enclosure also may be provided along the rear edge of structure 210. On the other hand, the paddle wheel(s) 215 typically will provide a certain amount of buoyancy to the structure 210, so that in certain embodiments such a separate rear enclosure would be superfluous. Anemia y dolor muscular . Thus, one embodiment of the invention is directed to an apparatus that includes: a paddlewheel having multiple individual paddles, an axis of rotation, a front side that is forward of the axis of rotation, and a rear side that is behind the axis of rotation; and a covering structure having a front portion that (a) covers a first part of the front side of the paddlewheel, leaving a second part of the front side of the paddlewheel uncovered by said front portion and (b) extends a distance forward of the front side of the paddlewheel, with the front portion of the covering structure being tapered, becoming thinner as it extends further forward of the paddlewheel.

Although the embodiments discussed herein generally assume that the pivoting ability is provided by pivotally attaching one of the elongated members to the end structures of the paddlewheel, such pivoting also (or instead) can be provided simply by loosely attaching the sheet of fabric or fabric-like material to the elongated member. As with paddle 476 (discussed above), paddle 660 preferably includes a sheet of fabric or fabric-like material 661 suspended between two elongated members 662 and 663. However, unlike paddle 476, elongated member 662 for paddle 660 preferably is pivotally attached (e.g., hinged) near the outer edges (or perimeters) of end structures 485 and 486, so that it is capable of rotating relative to end structures 485 and 486, and elongated member 663 is not directly attached to end structures 485 and 486, but rather is free to move, subject to the constraints described below.

33. Like paddle 660 (discussed above), paddle 745 includes a sheet of fabric or fabric-like material 746 suspended from two elongated members 747 and 748, with member 747 being pivotally attached to each of the end structures 485 and 486, and with member 748 being free to move in a constrained manner.

39), and a water current of 888 flowing into the rear opening of the housing is directed across the bottom portion of the paddlewheel 862, also causing the paddlewheel 862 to rotate in the clockwise direction (from the view shown in FIG. FIG. 35 is a perspective view of the support frame for a three-paddle paddlewheel. FIG. 38 is a center sectional view of a three-paddle paddlewheel in use.

26, but with the current flow from the opposite direction as compared to FIG. 4 and 5) can, e.g., be placed in a 5 mile per hour (MPH) current (e.g., tidal current). Dolor en las articulaciones de los tobillos . 3A and 3B, each individual paddle 38 preferably is curved, e.g., so that it generally resembles a longitudinal strip of a hollow cylinder, and is concave in the direction of the incoming water current. Thus, hinged, pivoting and/or collapsing paddles (as in the previous embodiment) often can provide less resistance to water current during that portion of their rotation when they are moving in the direction opposite to the current flow. More preferably, the entire system is configured such that maintenance or replacement of any operational component can be accomplished quickly and simply above water. 30, although in the preferred embodiments multiple such paddles are provided at equal angular intervals (e.g., four paddles at 90° intervals).
