Capture efficiency is highly dependent on wave length and period and only those bags facing oncoming waves have any kinetic (surge) energy capture effectiveness. Only those 3-4 bags (of 12) facing oncoming wave fronts capture any wave kinetic energy and performance is highly dependent on wave length and frequency, which varies greatly in actual random sea conditions. None of these prior art subsurface OWECs enhance or supplement energy capture with overhead floating bodies. Hundreds of uniquely different ocean wave energy converters (OWECs) have been proposed over the last century and are described in the patent and commercial literature.

9. To increase the Magnus force lift, the energy harvester is replicated within 1-20 diameters of the Magnus cylinder. In a hydro application embodiment, the energy harvester can be mounted in a self-floating configuration, and may be attached to a vessel or platform located in a current of 1 foot per second or greater, such as in a tidal channel. 1, 2 and 3. Here the energy harvester is mounted to a structure where the energy harvester is in communication with a fluid flow 90. As shown in FIGS. The submerged depth of said containers relative to mean sea level can be hydrostatically sensed and adjusted by adjustable buoyancy floating vertical mounting columns (or by hydraulic or electro-mechanical drives if attached to sea bed fixed mounts) for tides or sea states to optimize wave energy capture efficiency. Additional high density fixed ballasts 55 and a single or multi-point cable 60 and anchoring system 61 is attached to the lower portion of said columns 7 (shown) or to the shoal plane 40 (not shown).
5) were previously discussed (in the Background of the Invention) and in Rohrer 2010/0308590A1 incorporated herein by reference. 1-6 show prior art previously discussed and referenced. The Magnus force operates in a direction perpendicular to the axis of rotation of the cylinder, and because many prior art Magnus forces used the rotating cylinders in a fluid environment where the axis of rotation of the cylinder was horizontal, and the fluid movement was also horizontal but generally perpendicular to the axis of rotation of the cylinder, the resulting force direction was often in a vertical or “up” direction, and thus the term Magnus “lift” is often used to refer to this Magnus force, even when the actual direction of the force is not always in an upward direction. Only a few prior art substantially or fully submerged (“subsurface”) devices use gas filled variable volume or deformable containers like the present invention, producing container expansion or contraction in response to overhead swell and trough induced static pressure changes.

Wave energy capture efficiency can be enhanced by delaying or timing said compression and expansion until hydrostatic pressure and kinetic wave impact on said moving end is optimized via the use of pressure sensors and computer directed electric or pneumatic controls. A second movable rigid end or surface opposes said first fixed end or surface and is oriented towards oncoming wave fronts.
FIG. 10 is a semi-submerged side elevation sectional view of a downwardly sloped embodiment of the present invention utilizing an internal rib reinforced flexible bellows as said air or gas filled primary variable volume vessel preceded by a fixed shoaling plane. Dolor en la parte exterior de la rodilla . FIG. 12 is a semi-submerged side elevation sectional view of a downwardly sloped embodiment of the present invention utilizing a rib reinforced flexible bellows with a rigid moving front face preceded by and mechanically and pneumatically connected to a surface float with secondary venting expandable vessel. Said hollow vertical columns 7 also contain a compressed air storage tank 52 with control valve 53. The lower portion of said columns contain variable volume sea water ballast chambers 51. The compressed air (responding to hydrostatic pressure sensors and a programmed controller) displaces water 50 in said chambers to raise or lower float columns 7 and attached said vessel, either to optimize energy capture or to survive extreme sea states.

Bums recognizes the stroke and efficiency limitations of using wave induced hydrostatic pressure variations to compress a gas in a submerged container and attempts to overcome same by arranging multiple gas interconnected containers perpendicular to oncoming wave fronts. 6,700,217 describes a container and small diaphragm seal very similar to Burns and also without gas venting.
