Method, system and device for harnessing hydraulic head in large bodies of water

A method for channeling, elevating, conducting and retaining up to the sea shore the higher hydraulic head of the ocean surface waves, comprising:

• a) excavating the natural seabed to provide a base level up to a length, inside the sea, sufficient for a floating device to float;
• such excavation will depend on seabed characteristics and on the materials employed for building the floating device structure;
• b) building a plurality of pillars having their foundations resting on firm soil on both sides of the floating device on the landward end of the device, a couple of pillars are more inland and another pair is located closer to the sea;
• c) providing a plurality of sliding lateral supports located on said pillars and at the level of the top slab of a pontoon-like lower body of the floating device allowing free flotation and rotation on a vertical plane that contains its longitudinal axis, but impede the lateral or longitudinal movement of the device;
• d) installing such floating device on the are used to indicate the separate walls excavated seabed, in a manner that it is positioned as orthogonal as possible with the wave fronts of the selected location and that its location is consistent with the one of the pillars and sliding lateral supports;
• and
• e) repeating, at a location adjacent and lateral to the floating device, steps (a) through step (e) as many times as necessary to encompass a wave front width that suits the site conditions.
