Christmassy free motion quilting / CHARM ABOUT YOU A return spring 19 serves to elastically resist upward movement of the piston 18 and to retract the piston into the cylinder when the upward force on the cable 20 is relaxed as the float falls downwardly from a wave peak. SUMMARY OF THE INVENTION A system for converting mechanical energy from water body surface waves comprises a mechanical energy transducer and a wave energy capturing element secured to the transducer for transmitting mechanical energy to the transducer for conversion into useful, e.g., electrical, energy. Also, because it is possible to readily change the area or shape of the float while little affecting its buoyancy (e.g., by varying the lengths of extension of thin panels mounted on the float), it is possible to vary the energy capturing capacity of the float for various wave conditions.

FISIOTERAPIA A DOMICILIO - Clinica Alfa Water beneath the wave, however, tends to move in circular or elliptical paths, and it is this “local” movement of the water which is relied upon for causing corresponding circulatory movements of the float 22. Accordingly, to the extent that the float 22 can capture the energy in the surrounding “locally” circulating water and move in circular paths with the water, cyclically varying forces are transmitted along the cable 20 to the anchored transducer 12. Such variable forces cause a pumping action of the cylinder piston, hence produce variable hydraulic pressures and flows for driving the electrical generator for generating electrical energy. Being always fully submerged, the float provides an essentially constant upward force bias on the transducer, and a varying force, superimposed on the bias force, in response to movements of the float caused by wave induced circulatory motions of the subsurface water. This allows the transducer to adsorb the power rather than the power being wasted by stretching the elastic mooring line.

1. The system includes a known type of mechanical energy transducer 12 for converting variable linear forces and displacements to useful power. This provides flexibility both in the design and operation of the system. Typically, such systems comprise a float or buoy which floats directly on the water surface and which rises and falls with the passing waves. Thus, energy is generated, but at reduced levels, even when the float is removed from its normal position on the water surface.

By way of example, the transducer can include a hydraulic cylinder 14 suitable for pumping hydraulic fluid for turning a hydraulic motor 15 driving an electrical generator 17. Agujetas dolor muscular . The transducer 12 is firmly anchored in fixed vertical position relative to the floor 16 of the body of water in which the system is disposed. For example, for a given transducer having a preferred range of driving power, the buoyancy of the float can be selected for providing the proper constant force to maintain the system at its proper depth, while the area and shape of the float can be independently selected depending upon how the system is to be deployed and the amount of wave power to be collected.

As mentioned, the float remains fully submerged during operation of the system, and with a float of constant mass and volume, the upward force applied to the transducer owing to the buoyancy of the float remains constant. 1, the float remains always fully submerged (the dash line 24 indicating the maximum depth of the wave troughs) and the upward force on the float caused by the weight of the water displaced by the float remains essentially constant. The energy capturing element comprises a float so positioned, relative to waves of a preselected maximum amplitude, to be always fully submerged beneath the waves, but within the energy zone of the waves for causing movements of the float. While the floats typically remain on the water surface, for maximum energy capture from the passing waves, it is known (as discussed in U.S. The piston 18 of the hydraulic cylinder 12 is connected by a cable 20 to a float 22 having a positive buoyancy for exerting an upward force on the piston 18. The length of the cable 20 is selected to maintain the float 22 fully submerged beneath the water surface for waves of a preselected amplitude (as discussed hereinafter).
