More particularly, this invention relates to wave energy converters wherein either all or a substantial portion of the energy captured or produced is from one or more substantially submerged devices relying on overhead wave induced subsurface differences in hydrostatic pressure and surge or pitch which expand and contract or otherwise deform or deflect one or more air or gas filled variable volume containers, thereby producing useful work with a pneumatic, hydraulic, mechanical or linear electric power take off means resisting such compression or expansion. Referring to FIG. 11, each buoyant planar member 148 has a width WB that extends between its ends 162 and 164 and a length LB that extends between its sides 162 and 164. The lengths of the buoyant planar members are selected to be small, with the lengths being at least four or five times less than the wavelength of the smallest wave from which the assembly 20.1 is being designed to extract power.
Those skilled in the art will appreciate there are many other potential motion regimens that could be given based on application requirements including a regimen where the actuator is moved and held at a set position to hold a fixed position of the lens element relative to the display. The full range of motion of movable surfaces 2 and 3 are indicated by 15. Said first surface 1 is maintained in a relatively fixed position via rigid attachment to two bottom ballasted (not shown) vertical floating hollow columns 7. Air filled vessel 19 is vented to and from atmosphere through ducts 14 in pneumatic and rigid mechanical communication with hollow columns 7 through two way or self rectifying air turbine-generator 10. Venting column cap 11 allows air flow to said variable volume vessel from atmosphere without allowing sea water intrusion.
The contraction and expansion of the elastomeric dielectric 26 can be harnessed as motion. Pat. No. 4,630,440) uses a pressurized gas filled device which expands and contracts an unreinforced bladder within a fixed volume sea bed deployed rigid container in response to overhead wave induced static pressure changes. Apparatus including a coil supported on one end by a platform which reciprocates in response to wave action on a body of water.

Alternatively, in more moderate water depths, the columns 7 can be affixed directly to the sea bed 62 or slide up and down one or more columns, poles, pillars or masts (not shown) fixed or rigidly embedded to the sea bed 62. A down sloping shoal plane 40 with optional converging side shields 41, acting like an artificial beach, focuses and funnels waves towards said variable volume vessel moving hydrodynamic wave impacting surface 3 and any moving extension plates 44 thereon. Dolor en la parte posterior de la rodilla al doblarla . Bladder expansion and contraction within the container displaces sea water through a container opening driving a hydraulic turbine as sea water enters and exits the container.
