The faster falling of plunger 221 opens orifice 218, allowing water to enter the lowermost portion of the falling vessel, thereby relieving any reduction in pressure, and thus increasing the rate of the vessel’s 217 falling. Its flaps are free to open to allow ambient water to flow 918 into the damping vessel 914 which facilitates the flow of water out of the open top of the vessel without the creation of any regions of reduced pressure, which might impede the vessel’s descent. 903. And, wherein, the buoy’s tendency to keep its own longitudinal vertical axis coaxial with a longitudinal axis of the entire embodiment favoring the avoidance of the kind of wear and damage to the ribbon cable 904 that tends to result from the misalignment of the ribbon cable with the roller over which it passes. 59. So long as the cable 204 and/or 205 is pulled from a direction that lies within the pulley’s plane of rotation 203, damage to the pulley and the cable are minimized.

445, that is located at a point within the buoy, wherein that point lies within a cylindrical space centered about, and within a radial distance 444 of, the vertical longitudinal axis of the buoy. In addition to, or in lieu of, vertical rigid spacing rods, diagonally oriented rigid spacing rods can be provided, giving the inertial water trapping device the form of a linear truss or an elongate space truss, wherein horizontal plates 5201B are placed at intervals within the framework provided by the truss. And, any or all of such strategies can be implemented, within the power-take-off system of the same embodiment, in response to the detection of specific wave conditions, atmospheric conditions, farm electrical-grid conditions, etc. The inertial mass 1-140’s resistance to rising can be all the greater, in fact, because not only does the inertial mass have great effective inertia (and hence an inherent resistance to being drawn upward), but, when the converter is in a wave trough, the inertial mass can furthermore have a downward momentum developed during the converter’s earlier descent into the wave trough under gravity.

Because the pulley’s axis of rotation 1021 is about an axis normal to the page and passing through the planes normal to the page and intersecting the page at lines 1017 and 1019, the point 1015 at which the cable leaves the pulley and travels on to the traction winch remains unchanged. 88. Note that the cable 1011 is aligned with a plane at 1017, and normal to the page, that is coplanar with the pulley’s plane of rotation. Such a passive “feathering” mechanism has the advantage of allowing the system to shed the energy of a storm even if its normal control systems inadvertently go offline. At a threshold level of tension (primarily determined by the PTO and/or by its control system) the rollers of the torsion winch “unwind” allowing cable to joining the buoy to the inertial mass to effectively get longer. However, as flotation module 901 rises in response to an approaching wave, the submerged inertial damping mass 914 resists its upward acceleration creating a tension in the flexible connector 902. This tension results in the lengthening of connector portions 902 and 908, and the corresponding shortening of flexible connector portion 909. As flotation module 901 rises, and the inertial damping mass 914 resists that rising, the float 905 descends.

Another end and/or part of depending connector 1-150 can then descend through aperture 1-115 and be connected at 1-161 to restoring weight 1-160. One end of depending connector 1-150 is connected to inertial mass 1-140 and the other end is connected to restoring weight 1-160. An intermediate portion of depending connector 1-150 is operatively connected to pulley/capstan 1-125, e.g. Consequently, restoring weight 1-160 can be accelerated upward more rapidly and/or easily than inertial mass 1-140 and a net torque can be developed in pulley/capstan 1-125, causing the pulley/capstan to rotate in a first direction, turning shaft 1-122, and enabling the generator to generate electricity.

Pulley/capstan 4-125 a is operatively connected to pulley/capstan 4-125 b by an integral/single shaft 4-125 c that passes through bearing housing 4-125 d, which contains a bearing that bears said shaft 4-125 c. 412, one end of which rises from the water through the central aperture 417, and the other end of which returns to the water through a roller-specific peripheral aperture, e.g. As the buoy 100 rises on a wave, the inertia of the inertial mass 102 inhibits its upward acceleration thereby creating a forceful tension in the ribbon cable 103. Que sirve para el dolor de espalda . That tension is imparted to pulley 104 as a torque. Instead, directionally rectifying pulleys 91-7 are used, which allow flexible connectors 92-4 to always feed onto the groove in pulley 91-7 without an incident angle, regardless of the angle of flotation module 91-1 or its relative position or angle to IM 92-11. Flexible connector 92-4 is shown to be constructed of a single tensile element.

A buoy 560 is approximately radially symmetrical about a vertical axis through its center, and every cross-section through the buoy has an approximately hemi-circular shape with respect to a vertical plane passing through its center. Flotation module 200 is shown to contain two apertures 202 and 203 which vertically pass through the entire structure of flotation module 200. Pulleys/capstans/sheaves (“drums”) 206-210 can be arrayed linearly as shown, with flexible connector 204 passing alternatively above and below adjacent drums in a serpentine manner (detailed further in FIG. Que es dolor de espalda . Lifting module 571 is buoyant and floats on the surface of a body of water 570. Inertial mass 581 is submerged and suspended beneath the lifting module and can contain and/or at least partially entrap a large mass of water. Modules 2306-2307 may contain additional power take-offs and sensors (e.g., of angular frequency, of torque, of angular displacement or velocity or rotation rate, of the shaft/capstan 2303, etc.).
