212, taken across a vertical plane passing through, and parallel to the longitudinal axis of, the power-take-off (PTO) 192 and the upper-most beam 193 in which it is embedded. 193 is a tube with a medial partition wall. 180 partition when the vessel is moving downward. And, when the inertial mass falls under gravity owing to its effective negative buoyancy during operation, a large mass of water is accelerated downward and the momentum of this water contributes to the development of power when the upward lifting force imparted by the flotation module subsequently accelerates the inertial mass in the opposite direction. Each crank axle’s axis of rotation is not coaxial with its respective radial axis of symmetry. Not shown are the inertial mass and a complementary restoring weight connected to opposite ends of flexible connectors 296 and 297, respectively, (which are two sides of the same flexible connector). When the distance between the buoy 520 and the inertial mass 530 decreases, the weight of the restoring weight 534, pulls the ribbon cable so as to eliminate slack in the cable and reset its position in preparation for the next increase in separation between the buoy and the inertial mass.

Dolor de piernas. Cómo Evitar las Piernas Cansadas.. The reason for this is clear, as the oceans and seas will be able to provide a constant, renewable, natural, pollution-free source of energy if its energy can be harnessed in an economical and reliable manner. The embodiment’s ability to systematically extract energy from ocean waves depends upon its ability to “reset” after it has “launched” its inertial mass downward, and extracted power from its downward movement. FIG. 210 is a modular wave energy extraction system in which the complementary vertical oscillations of a water-filled canister (an inertial mass) 3043 and a restoring weight 3039 drive a shared flexible connector 3030, 3040 and 3042 around two pulleys 3032 and 3052, either or both of which may be connected to a generator. Because inertial mass 2B-140 has relatively much larger effective mass (inertia) than does the restoring weight 2B-160, it is easier for restoring weight 2B160 to be accelerated up than for inertial mass 2B-140 to be accelerated up.

FIG. 62 shows a side cross-sectional illustration of a buoy 320 connected to a submerged inertial mass 324 by a cable 325, that is driven along a circular path by waves 328 passing through the surface 328 of a body of water on which the buoy floats. In its “safe mode” configuration, the inertial mass can allow significant passage of water through its interior, e.g., along its vertical axis, e.g., across a horizontal plane. 102 center, and every cross-section through the buoy has an approximately hemi-circular shape with respect to a vertical plane passing through its center. In some embodiments having a direction rectifying flotation module, a plurality of pulleys/capstans are spaced from the center of the flotation module, e.g.

A buoy 100, flotation module, floating platform, and/or buoyant object, floats adjacent to the surface 101 of a body of water. The resulting torque 214 between the pulley and its shaft and/or supporting bearings may also cause damage and/or fatigue. The gear 1004 is operatively connected to the flexible connector 1002-1003. The gear 1004 is positioned within a recessed area 1001 in the bottom of the buoy that allows the gear and its flexible connector to communicate with the body 900 of water upon which it floats.

143, that hold each respective directional rectifying pulley and allows it to rotate, by means of a respective bearing, e.g. 133, then pass around and/or over a respective directional rectifying pulley, e.g. Es normal tener dolor de espalda durante el embarazo . Thus, an embodiment that utilizes a “well-balanced” buoy will require the application of less differential torque by means of its pulleys in order to maintain the proper relative position and/or orientation of its respective inertial mass. In one embodiment, the “wet weight” of the chain 19 is less than the wet weight of the inertial mass, so that in the absence of wave-induced lifting of the buoy, and an associated pulling up of the portion of the ribbons connecting the buoy to the inertial mass, the inertial mass would tend to sink under its own wet weight, overcoming the upward counterforce imposed by the chain via the ribbon. The principle of operation of the disclosed converter is the harnessing of (principally vertical) motion differentials between a buoyant “flotation module” and a submerged, suspended, and (in a preferred embodiment) water-filled “inertial mass.” As such, the disclosed converter can be described as being of a “single-mode” and “heavemode” design.
