In this embodiment the float member 48 is of spherical configuration and is slidably mounted on the vertical column of the support structure 45. The apparatus 44 also comprises a linear electric generator 49 having a stator provided in connection with the vertical column of the support structure 20 45 and a translator integrated into the body of the float member 48. Operation of the wave converting apparatus 44 of this embodiment, for converting ocean wave energy into electrical power, is similar to that of the first embodiment 10 and will not be described in detail again here. These low friction guides can typically be implemented as a sealed bearing surrounded by a plastic or rubber sleeve (not visible) located on the float member 18, with a corresponding channel or guide located on the stator 22. Other possible configurations for low friction guides will be evident to persons 30 skilled in the art.
As water particles in the crest of a wave encounter the float member 18 they are forced downwards by the hydroplane surfaces 30. This produces an upward force on the float member 18. On the other hand as the water particles encounter the PBSM 14 they are – 11 forced upwards by the inclined upper surface 40. This produces a downward force on the PBSM 14. Hence, when a wave encounters the apparatus 10 there will be an upward force acting upon the float member 18, and a downward force acting upon the PBSM 14, due to the wave’s horizontal 5 motion.

Once the switch is opened the shunt to the solenoid will be opened, thus allowing the PBSM 25 14 to rise in altitude and relieve the upward stress provided by the float member 18. This altitude adjustment will continue until such time as equilibrium is achieved. The automatic control system of the apparatus 10 is such that all wave frequencies outside of the predefined operational range will be passed by the whole of the support structure 12 and not just the float member 18. This 5 approach will allow the system to automatically calibrate itself to the prevailing mean water level, thus allowing it to adjust to tidal fluctuations, storm surges and other low frequency phenomenon, which if not planned for could lead to the destruction of the wave energy converter. In the illustrated embodiment the buoyant means is in the form of a buoyancy tank 25 16 provided within the submerged member 14, as will be described in more detail below.

An alternative configuration is for the counterbalancing means 64 to be constructed solely of denser than water material (such as concrete) and that the caddy 72 is the adjustable buoyant chamber used to raise and lower the counterbalancing means 64. 30 The linear electric generator 20 used by the apparatus 10 is designed to provide the optimal frequency response and EMF to allow the most amount of energy to be extracted from the waves of the ocean.
If the apparatus 10 moves away from the shortest distance between the ballast and the PBSM, a corrective force will come into play that will return the system to the shortest distance between the two points. In the illustrated embodiment the stator 22 is connected to the submerged member 14, while the translator 24 is connected 10 to the float member 18. In reality both of these parts will be moving, though for the sake of adhering to popular naming conventions, the terms “stator” and “translator” will be used to refer to the predefined WEC structures. When wave motion causes a suitable differential motion between the float member 18 and the support structure 12, the translator 24 is translated relative to the stator 22 and the linear electric generator 20 generates electrical power. The first is as a buoy floating on top of the water, with an attachment linking the buoy to its reference frame; the buoy will then move with the waves on the ocean’s surface producing the differential motion 15 relative to the frame of reference.
Throughout the specification, unless the context requires otherwise, the word 20 “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers. Figure 14 20 illustrates an embodiment of the apparatus 44 with a plurality of solar panels 108 mounted on top of the wind turbine 100. In other respects the wave energy converting apparatus 44 of this embodiment (and of the previous embodiment) with its associated tension mooring system 50 is substantially identical to that of the embodiment illustrated in Figures 8 to 11 and will not 25 be describe again here. Inflamacion de colon y dolor de espalda . A dome 104 visible on top of the turbine may be used to house the transmitter and/or a GPS or some other form of positioning beacon. In the illustrated embodiment the 10 buoyant means is in the form of a buoyancy tank 47 (not visible) provided within the submerged member 46. As with the previous embodiment, the buoyancy tank 47 is normally filled with sufficient air to give the submerged member 46 an overall positive buoyancy.

Figure 5 illustrates a preferred embodiment of the mooring caddy 72. The PBSM 14 is secured in the mooring caddy 72 by a suitable locking mechanism, which may automatically secure the PBSM 14 as it docks in the mooring caddy 72. In the illustrated embodiment the PBSM 14 is manually secured to the mooring caddy 72 via securing bolts 74. The 25 braking system 70 and pulley mechanism 68 are preferably housed in the mooring caddy 72. All the components required to implement the wave energy converting apparatus of this embodiment may be housed in the mooring caddy 72. The mooring caddy 72 preferably has its own buoyancy tank 76 (not visible) which can be filled or evacuated with compressed air as 30 required to lift or lower the caddy 72 in the water during docking, maintenance or operational situations.
30 – 17 Figures 8 to 11 illustrate a second embodiment of a wave energy converting apparatus 44 and its associated tension mooring system 50 in accordance with the invention. A possible embodiment of the -8 tension mooring system in accordance with the invention may also itself be used to extract energy from the heave of a wave, as will be described in more detail below. A tension mooring system in accordance with the invention is employed in association with the WEC to achieve this tuneability. Dolor de espalda intenso . In this manner the resonant frequency of the wave energy converting apparatus 44 and its associated tension mooring system 50 can be adjusted to “tune” it to 20 the prevailing ocean conditions. Figure 15 illustrates a fourth embodiment of the wave energy converting apparatus 110, which is similar to the embodiment 44 of Figures 8 to 11 and hence the same reference numerals will be used to identify the similar parts.
The dominant and/or most energy dense frequencies will be determined through calculation using well 5 known formulae. Another major drawback of such prior art systems is the need to be close to shore where the energy loss for 5 shoreline waves is high due to frictional losses, thus missing out on the majority of the wave energy present in ‘deep’ water. Preferably the hydroplane surface 30 is one of a plurality of substantially parallel hydroplane surfaces 30 extending perpendicularly to and along respective 10 first and second sides of the float member 18. The hydroplane surfaces 30 are inclined downwards from the front end 32 to the rear end 34 of the float member 18. This configuration ensures that water particles in an approaching wave are forced downwards by the hydroplane surfaces 30, creating hydrodynamic forces acting upwards on the hydroplane surfaces 30 which 15 are added to an upward force acting on the float member due to its buoyancy.

In the past many wave energy converters have been lost during storm conditions due to exposure to excessive wave energy densities. The typical prior art approach to extracting wave energy has been to use a turbine or hydraulic system. Such a novel use of heave increases the survivability of the WEC without sacrificing the efficiency of the energy extraction. A single heaving body uses a buoyant mass on top of the surface of the water 5 to extract the vertical energy of a wave. For wave energy extraction to take place there needs to be energy absorption from one or both of these orthogonal energies. 20 An air compressor 94 is provided within the mooring caddy 80, for pumping air down to the counterbalancing means 53 via air hose 57. Some of the power generated by the generators 86 can be used to power the air compressor 94. Air compressor 94 is also under the control of control system 92. An air conduit 96 supplies air from atmosphere to the air compressor 94, 25 and extends upwards through the submerged body 46 to a point above the water line.
Preferably the dampening means, pulley mechanism, air compressor and an adjustable buoyancy tank are all housed 15 in the mooring caddy. Preferably the submerged member is secured to the mooring caddy by a locking mechanism. Preferably the mass of the base 56 of the vessel 55 is set to match the minimum desired operating frequency of the system. It typically also has a volume less than or 20 equal to the volume of the submerged member 14. The combination of these two parameters makes the mass of the floating member 18 less than or equal to half the mass of the PBSM 14. The buoyancy of the PBSM 14 provides an opposing force sufficient to counter the downward force produced by the linear electric generator 20 on its downward return stroke.

The proportion of braking will be dependent upon the amount of current being produced. Anemia y dolor muscular . The pulley mechanism 54 is housed in a mooring caddy 80, which is illustrated with a transparent wall in Figures 11 and 12. The mooring caddy 80 is of cylindrical shape in this embodiment to match the shape of the submerged member 46, and may be permanently or releasably attached to 30 the bottom of the submerged member 46. As can be seen most clearly in Figure 11, the pulley mechanism 54 comprises a pulley 82 fixedly mounted on a shaft 84 which is rotatably mounted between a pair of rotary electrical -19 generators 86a and 86b. As the shaft 84 oscillates, the generators 86a and 86b will generate an EMF and offer resistance to the rotary motion of the shaft. Advantageously the upper surface of the submerged member 46 is of substantially hemi-spherical configuration, so as to act as a deflecting surface for the water (not unlike the upper surface 40 of the first embodiment), to further enhance this differential motion.
