Dolor de espalda en el lado izquierdo: ¿a qué se debe? As noted above, in the preferred embodiments barge 400 is used primarily to fabricate structures 420 that are made primarily or substantially entirely of concrete, such as the anchors and/or the housings for any of the energy-generating units described herein or in any of the patent documents incorporated herein by reference.

The crane 410 is used to lift and move equipment and material on and off the barge deck 401. For example, one of the main purposes of barge 400 preferably is for fabricating large concrete castings (e.g., castings having a maximum dimension of more than 50, 75 or 100 feet, meaning that barge 400 preferably is even larger than such anticipated maximum dimensions). FIG. 22 is a perspective view of a portion of a paddlewheel having paddles made primarily of a sheet of fabric or fabric-like material according to a representative embodiment of the present invention. At the same time, because each uses a fabric or fabric-like material the precise shape of the paddle can be formed dynamically, e.g., for increased efficiency. Because a larger volume of water is directed across the top half of the paddlewheel 650, the paddlewheel 650 turns in a clockwise direction (from the left-end perspective shown in FIG.

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. In FIG. 25, for ease of illustration, just a single paddle 622 (comprised of parts 622A and 622B) is shown.

Each of parts 622A and 622B includes a rod 623A and 623B, respectively, that is pivotally attached (e.g., hinged) to end structures 485 and 486 and an edge 624A and 624B, respectively, that is unattached. In the embodiments described above, the paddlewheel typically has four individual paddles and solid, circular (or disc-shaped) end structures. In addition, structure 210 can be attached to the riverbank 235 using cables (not shown) and/or, in situations where the water level of the river is expected to change significantly, ramp 237 can be pivotally attached to riverbank 235 at its proximal end 238 to accommodate corresponding changes in the position of ramp 237. As a still further alternative, structure 210 can be held fixedly in place (rather than, or in addition to, being tethered to anchor 230), e.g., using pilings. In certain embodiments, the depth of the energy-generating unit is desired to be adjustable, e.g., so that it can be initially placed or subsequently adjusted so as to be located within the maximum current stream and/or so that it can be adjusted over time based on changes in the water level (e.g., due to tides or changes in the amount of water in a river).

FIG. 9 is a left side center sectional view of a subsurface energy-generating system that is particularly adapted for use in a stream or river. FIG. 2 is a center sectional view of an energy-generating unit for a subsurface wave energy system. After the system has been fully deployed, as shown in FIG. The poured concrete preferably is permitted to fully cure in the water.

FIGS. 13-16 illustrate an example of how the foregoing energy-generating system preferably can be transported, deployed and maintained, as well as how the energy that it produces can be converted to a gas that is stored and transported. 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. Baja por dolor lumbar . Thus, for example, with reference to FIG.

For this purpose, crane 410 preferably is used, e.g.: to bring in concrete forms and prefabricated components to be embedded within the concrete castings (such as ballast tanks); to pick up a concrete hose and pour concrete from it into the forms; and to bring in and place other components to be attached after the concrete castings have cured (such as generators and paddle wheels). 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 entire system preferably is deployed with a tug boat, e.g., in the manner described in the ‘587 application, with the anchor 70 being sunk, the deadweight anchor 75 being dropped, the hose/cable pair 74 being attached to the buoy 76, the energy-generating unit 10 having positive buoyancy and being cabled to the anchor 70 in a direction facing the incoming waves at a position below the surf line 80. However, unlike many of the previously described systems, due to the present system’s expected proximity to the shore, some onshore cable-positioning assistance preferably is provided (e.g., using an onshore tractor). In such cases, the anchor cables preferably are capable of being adjusted, e.g., by including a winch on the anchor, on the energy-generating unit, on the deployment vehicle or on the shore. Energy-generating unit 100 preferably is fairly large, e.g., at least 50, 75 or 100 feet in width (e.g., with each paddle wheel 105 being 24 feet long), at least 20-40 feet from front to rear, and at least 10-20 feet deep.

4, the front and rear halves of energy-generating unit 100 exhibit mirror symmetry, thereby allowing equally efficient operation irrespective of the direction in which the water current is flowing. Also similar to energy-generating unit 100, energy-generating unit 460 has a sloped lower surface 494 that funnels the water (e.g., tidal) current 495 during the desired portion (in the present example, the bottom half) of the paddlewheel 475. The upper surface 465 of covering structure 463 preferably is of the same (or at least approximately the same) angular slope as the lower surface 494, which will tend to balance the energy-generating unit 460 in the water current. 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.

Preferably, the portion 496 of the lower surface 494 that is immediately above the paddlewheel 475 is arc-shaped (or, more precisely, in the shape of a longitudinal slice of a hollow cylinder) and closely conforms to the outer perimeter of the paddlewheel 475 (e.g., the outer reach of the individual paddles 501-504). Dolor muscular intenso . As a result of this structure, the current flow tends to move across the paddlewheel 475, with a smaller amount circulating back through. FIG. 25 is a perspective view of a portion of a paddlewheel 620 having a basic structure that is similar to that of paddlewheel 475 (shown in FIG.
