WAVE ENERGY CONVERTER WITH ROTARY HYDRAULIC SPRING
The generally up and down movement of a reaction mass is converted into rotary motion which is used to drive a rotary hydraulic spring comprised of a rotary hydraulic pump motor and an accumulator to produce a "spring" function. The invention is particularly applicable to wave energy converters (WECs) having a reaction mass which needs to be coupled to a spring to ensure Its oscillation and to cause it to be centered about its center of travel. The linear up-down motion of a reaction mass may be converted via a linear-to-rotary translator to rotary motion to drive a rotary hydraulic pump/motor so as to provide spring action to the reaction mass and ensure its oscillation and proper positioning.

WAVE ENERGY CONVERTER WITH AIR COMPRESSION (WECWAC)
A wave energy converter with air compression (WECWAC) includes a cylinder and a piston located within the cylinder dividing the cylinder into an upper chamber and a lower chamber. The cylinder is fixedly attached to a spar whose up/down (heave) motion is restrained. The piston is fixedly attached to, and driven by, a float which moves generally in phase with the waves. Under typical wave conditions the piston functions to compress air within the upper chamber on its up stroke and within the lower chamber on its down stroke, i. e., the system is thus double-acting. In still water, the spar and cylinder combination is designed to drift down into the body of water relative to the piston whereby the size/volume of the upper chamber is decreased (while that of the lower chamber is increased). For small amplitude waves the piston continues to compress air in the upper chamber and this asymmetrical compression continues until the waves reach a predetermine level when 'double-action' is resumed. Controlling the position of the cylinder relative to the piston enables the WECWAC to automatically regulate its compression 'stroke' to suit varying wave conditions. The pressurized air from a WECWAC may be stored and/or processed to drive a turbo-generator or it may be combined with the outputs of other WECWACs to drive a single large and highly efficient turbo-generator.

A damping (or heave) plate comprises a generally flat plate attached, beneath the surface of a sea, and in horizontal orientation, to a structural member subject to being vertically moved in response to passing surface waves. The plate tends to resist vertical movements and has the effect of adding mass to the structure. A vertically extending structure is added to both major surfaces of the heave plate for increasing the volume of water moved by the plate. For minimizing drag forces generally created by use of the damping plate, the vertically extending structure is shaped to include curved hydrodynamic surfaces for minimizing turbulence in the surrounding water.
Apparatus embodying the invention include a damping plate attached to the submerged end of a spar-like element floating in a body of water. The spar like element tends to move up and down in a vertical direction in response to passing waves. The damping plate has a pair of oppositely facing surfaces extending transversely to the vertical direction of the movement of the spar-like element and vertical structures (“lips”) mounted on the oppositely facing surfaces for increasing the effective mass of water pushed during movement of the damping plate through the water. Damping plates with lips, as per the invention, may be used in wave energy converters to control the relative motion between the spar-like element and a float to increase the energy produced.
The stability and power conversion efficiency of a wave energy converter (WEC) which includes a float, a spar and a power taken device (PTO) connected between the spar and the float is increased by connecting a heave plate to the spar in a very secure manner and by carefully limiting the movement between the float and spar to one direction (i.e., up-down motion). Buoyancy chambers may be attached to the WEC to facilitate its transportation and deployment. The WEC may be formed in sections and assembled at, or close to, the point of deployment.

For reducing the number of components required for mooring (by- means of three, 120° spaced apart mooring lines) multiple floating wave energy converters (WECs), a group of six WECs is disposed in a hexagonal pattern with each WEC being disposed at a corner of the hexagon. The WECs are connected to one another by mooring lines extending along sides of the hexagon, each WEC thereby being connected by two, 120° spaced apart mooring lines and with each WEC serving as a mooring point for each of its two adjacent neighbors. A third mooring line for each WEC, spaced 120° from the other two mooring lines, is connected to an auxiliary surface buoy and thence to an anchor.
A wave energy converter (WEC) includes a shell suitable for being placed within a body of water. The shell contains an internal oscillator comprising a “reaction mass” and a spring mechanism coupled between the reaction mass and the shell. The shell and internal oscillator are constructed such that, when placed in a body of water and in response to waves in the body of water, there is relative motion between the shell and the internal oscillator's mass. A power take-off (PTO) device is coupled between the internal oscillator and the shell to convert their relative motion into electric energy. In systems embodying the invention, the spring mechanism is designed such that its displacement or movement is less than the displacement or movement of the reaction mass. The spring mechanism may be any device which enables the reaction mass to undergo a given replacement while its displacement or movement is less than that of the reaction mass. This property enables the size of the WEC to be more readily controlled (e.g., made smaller).

A wave energy converter (WEC) for converting energy contained in surface waves on a body of water to useful energy comprises two floats movable relative to one another in response to passing surface waves. Both floats comprise expandable outer envelopes which have been expanded into full and firm shape. In one process, expansion is obtained by filling the floats with fluids, for example, air and water. The fluids can be pumped into the floats, or the floats can be mechanically expanded in the presence of the fluids for self filling owing to pressure differentials. In one embodiment, a float envelope can comprise of plurality of end to end connected length sections in nested or telescoped relationship. Expansion is obtained by pulling the telescoped sections out from one and other, for example, by pumping fluids into the telescoped sections.
An ocean wave energy converter (WEC) utilizes the relative motion between permanent magnet and induction coil assemblies to generate electricity. The permanent magnet assemblies and induction coil assemblies are separately housed in watertight enclosures, enabling a wide range of wave energy converter configurations, nearly unlimited stroke and obviating the need for a common magnet/coil enclosure with seals. The magnet assemblies are constructed with surface or buried magnets. The wave motion moves a magnet assembly relative to a stationary coil assembly, or vice versa. Either the magnet assembly or the induction coil assembly are made long enough to provide the generation of electricity over a desired operational range of travel. Various means are provided to maintain the spacing (“gap”) between the magnetic and coil assemblies relatively constant.
