11 In this specification and the accompanying claims, the term “elongate”, in the context of describing a 3-dimensional body having a length, width and depth, is intended to mean the length of the body is greater than its width and depth. When interpreting each statement in this specification and claims that include the term “comprising”, features other than that or those prefaced by the term may also be present. More preferably, the 30 sub-frame is securely and rigidly fixed to the active float such that the active float has one degree of freedom in that it can pivot relative to the reactive body. Preferably, the power output system is arranged to actively control the torque loading on the pivot axis in accordance with forward prediction of wave motion in order to enhance 10 the useful energy captured. 20 In one form, the arms of the reactive body are integrally formed with the main body of the reactive body.

20 In a second aspect, the present invention broadly consists in a self-reacting and floating wave energy converter for extracting electrical energy from wave motion in a body of liquid comprising: an active float that is arranged to float substantially toward or on the surface of the liquid, and being arranged to both heave and surge in response to wave motion acting on the active float; an elongate reactive body longitudinally extending between a top end 25 and a bottom end, and having a center of mass located at or toward its bottom end and below its center of buoyancy such that it is arranged to be suspended in a substantially upright vertical position and substantially submerged state into the liquid below the surface, and the reactive body having sufficient surface area and length extending into the liquid from the surface such that it pitches about a center of rotation axis located at or toward its 30 bottom end in response to wave motion acting on the reactive body, the active float and reactive body being pivotably coupled at or toward the top end of the reactive body for pivotable movement relative to each other about a single pivot axis in response to heaving and surging of the active float and pitching of the reactive body caused by wave motion in 10 the body of liquid, and wherein the active float and reactive body are pivotably coupled to allow the active float to fully rotate 3600 about the single pivot axis; and a power output system that is operatively driven by the pivotable movement about the pivot axis to generate electrical energy.

Energy in the moving water is alternately 5 converted between varying kinetic energy (resulting from velocity variations and the water inertia) and varying potential energy (resulting from pressure variations and the water weight). Preferably, the reactive body-to-active float weight ratio is in the range of 5:1 to 30:1. 5 More preferably, the reactive body-to-active float weight ratio is in the range of 10:1 to 20:1. Preferably, the reactive body comprises a main body from which two spaced-apart arms extend, the active float being pivotally coupled between the arms for pivotal movement 10 about the single pivot axis relative to the arms in response to motions of the active float and/or reactive body caused by wave motion in the body of liquid, the arms being of sufficient length to enable the active float to fully rotate 3600 about the pivot axis in response to substantial wave motion.

The general topology underlying the preferred form wave energy converter will now be described with reference to extracting useful energy from the sea or ocean in which wave motion may be provided in the form of waves, swells, currents, or any combination thereof. A successful wave energy conversion device must maximise interaction with these energy vectors, which are continually changing over time 20 intervals spanning from seconds to years. 30 In this specification and the accompanying claims, the phrase “medium inertia” in the context of describing a solid body is intended to mean the solid body has an inertial response time when subjected to the wave excitation forces in the direction of interest 12 which is of the same order as the period of the wave with which it interacts.
This path is in the direction of wave travel, with 15 the water moving directly forward on the crest and directly backward in the trough. 15 Preferably, the pivot axis is parallel to the center of rotation axis of the reactive body and is non-stationary and un-constrained such that its position oscillates relative to the body of liquid at least in the horizontal direction in response to surging of the active float and pitching of the reactive body. More preferably, the reactive body is substantially defined by a length extending between its top and bottom ends, a width that is perpendicular along the longitudinal axis between the top and bottom ends, and a depth that is perpendicular to the longitudinal axis and the width, wherein the length is larger than the width, and the width is larger than the depth, so as to form a substantially elongate substantially plate-like 20 reactive body.
From the continuously varying particle velocity and acceleration it is clear that many more frequencies than the fundamental are present. Preferably, the active float has a specific gravity of less than one. 8 Preferably, the coupling system further comprises a rectifier system that is arranged to convert the oscillatory pivotable movement at the pivot axis into rotational movement in one constant direction for driving the electrical generator. 25 In another form, the coupling system of the power output system is arranged to indirectly couple the pivotable movement at the pivot axis to the rotational drive shaft of the electrical generator via a gearbox system, the gearbox system being arranged to convert the oscillatory pivotal movement having a higher force and lower speed into a lower force at 30 higher speed for driving the electrical generator.

It will be appreciated that the wave energy converter may also be arranged to operate in other bodies of liquid that have sufficient wave motion to excite the wave energy converter. More preferably, the first and/or second ends of the active float act as a drag surface upon which 20 wave motion acts to create drag force to enhance surge movements of the active float. In this specification and the accompanying claims, the term “pitch”, unless the context 30 suggests otherwise, is intended to describe a particular form of movement of a body in response to wave motion excitation forces acting on the body, and in particular it is intended to cover rotational movements of the body in the liquid, such as sea water, that about a center of pitch on the body and which are caused primarily by hydrodynamic forces.
A common type of point absorber is known as a self-reacting heaving buoy system that utilises a heaving buoy which reacts against a drag plate suspended and submerged below 10 the active wave energy region, or an internal inertial mass which is designed to resonate at the wave period. Dolor de pierna en el embarazo . In particular, the main float is designed to resonate with the waves in the heave and the heave of the sub-float also causes the main float to pitch. Wavelength devices physically span the waves from crest to crest to provide a floating reference for the wave displacement forces, and are therefore very large structures of at 25 least 100 to 200 metres in length.

15 Figure lb illustrates how water particle motion in real seas departs from the ideal. In another form, the active float comprises one or more hydrofoil-shaped components extending from the underside of the active float into a submerged state below the surface of the liquid, the hydrofoil-shaped component(s) having an orientation relative to the active float that is arranged to create lift force to enhance heave and/or surge 30 movements of the active float as wave motion acts on the hydrofoil-shaped component(s).
