Noticias de Salud: Expertos internacionales en.. As with the embodiment shown in FIG. So as to facilitate easy storage and transportation of the wave energy converter, the sleeve, diaphragm and spine are preferably formed to define a flexible, layflat construction. Consequently the natural bending frequency of the sleeve is inherently too high to permit efficient extraction of wave energy from waves incident on the sleeve. These flexural waves drive movement of the spine and the diaphragm to drive pockets of air retained between opposite sides of the diaphragm and the sleeve at wave velocity along the inside of the sleeve to produce air power. The flow of air into, through and out of the wave energy converter 10 may be described with reference to FIGS. This enables the wave energy converter to be arranged so as to extend in a normal manner relative to the direction of travel of incident waves so that the waves may be harnessed to drive movement of the spine and diaphragm when the loading device is operated to apply an axial compressive force to the spine.

Preferably the method further includes the step of operating the loading device of the wave energy converter to adjust the axial compressive force applied to the spine so as to buckle the spine and the diaphragm into a waveform having a wavelength corresponding to the wavelength of the incident waves. FIG. 4 illustrates schematically a section of the sleeve 12 of the wave energy converter 10 floating a calm liquid surface 32 following operation of the loading device 25 to apply a constant axial compressive force to the spine 24, relative to the sleeve 12, so as to buckle the spine 24 and diaphragm 22 to define a waveform 26. As will be appreciated, the amplitude of the waveform 26 is limited by the internal dimensions of the sleeve 12. In the absence of any incident waves, the waveform 26 defined by the spine 24 and the diaphragm 22 remains stationary.

Any compressed air tank and/or air turbine is preferably located, in use, on land so as to reduce the mass of the wave energy converter, the air tank and/or air turbine being connected to the air outlet of the sleeve via a compressed air pipe or a flexible riser connection. If a wave energy converter produces compressed air at 6 bars or above, then it becomes a practical and cost effective proposition to pipe the compressed air to land for conversion to electricity. A solution involves locating wave energy converters on the shoreline, where the energy levels and thus destructive power of waves are less than at sea, and thus where operating and maintenance costs of the wave energy converters are significantly less than for sea-based devices.

8 relative to the liquid surface 32 is lower than the suction waterline 33 of the sleeve 12 relative to the liquid surface 32. This is caused by the loss of air, due to wave action, that creates lower air pressure beneath the sleeve 12. During wave action, the fins 42 allow air to escape, causing the edges of the fins 42 to sink due to suction, thereby preventing the inlet of air. The resultant suction resists movement of the planar contact surfaces of the fins away from the liquid surface, which in turn acts to hold the sleeve in floating engagement with the liquid surface. Attenuators generally consist of relatively long, floating devices, which are typically flexible and operate normal to the wave front so as to effectively ride the waves.

Such attenuators are simple and have few moving parts at sea, and could therefore provide a very competitive solution for harnessing wave energy. As a result, numerous patent applications have been filed covering wide-ranging ideas for wave energy converters that seek to exploit this vast energy resource. Hence, vertically acting reaction forces required between the wave energy converter and the surface of the body of liquid would be minimal to maintain the wave energy converter in contact with the surface of the body of liquid and would only harness a minimum amount of energy from the incident waves to drive movement of the spine and the diaphragm.

As outlined above, vertically acting reaction forces between the wave energy converter and the surface of the body of liquid are required to maintain the wave energy converter in contact with the surface of the body of liquid and to facilitate effective harnessing of the incident waves to drive movement of the spine and the diaphragm. In other, relatively higher operating pressure embodiments of the wave energy converter, the sealing engagement between opposed elongate edges of the diaphragm and the sleeve may be achieved through the use of a diaphragm sealing strip having elastic hinges that fit loosely in a flexible sleeve to accommodate the hinge arrangement. The transition between stable states will take place near the points of inflexion of the waveform in the form of an inverting seal action of the diaphragm that pumps the air along the sleeve.

The ends of the spine 24 and the diaphragm 22 are located centrally by guides 23 and under a constant axial compressive force ACF provided by the loading device.
