On the other hand as the float member 18 returns to its lowered position, as shown in Figure 6b, it produces electrical power due to the excess buoyancy of the PBSM 14 held 15 in position by the braking system 70. When the braking system 70 is off the counterbalancing means 64 is able to move freely up or down on cable 66. By means of this simple control system it is possible to implement an effective and adaptable means of controlling the motion of the PBSM 14. By only engaging the braking system 70 when energy is being produced, there will be 20 a general decrease in unnecessary stress on the system for times when no energy is being produced. This approach is different to 30 prior art devices, which only use the heave response of the body(s) to generate their energy.

In this embodiment the canister 122 has a wind turbine 100 mounted on top, similar to the embodiment of Figures 8 to 11. The tension mooring system 120 operates in a similar way to the embodiment of Figures 8 25 to 11, except that in this case the control system is configured to enable the electric generators 86 to operate at maximum efficiency to generate electrical power as they are not now required to act as dampening means.

The turbine is oriented to rotate about a vertical axis and is provided with a series of vanes 102 to capture the wind and generate electrical power. In an alternate embodiment the submerged member 14 is filled with sufficient air to ensure that the -9 submerged member has a total mass equal to the mass of the water it displaces, i.e. When the apparatus 10 is to be commissioned it will be attached to the exposed caddy 72, after which the counterbalancing means 64 will be filled with water, thus automatically setting the apparatus 10 into its correct working position, without the need for divers and highly specialized equipment. The open bottom of the mooring caddy 80 creates an air chamber 112 that 5 can be partially filled with air so as to give the mooring caddy neutral buoyancy.

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.

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. The front end 36 is narrowed to a V shaped tip and PBSM 14 has a V-shaped hull like a boat, as can be seen 20 most clearly in Figure 1. Preferably the PBSM 14 has a substantially planar upper surface 40 which is inclined upwards from the front end 36 to the rear end 38 of the submerged member, wherein water particles in a wave approaching from the front are forced upwards by the planar upper surface 40 creating a downward force acting upon the PBSM 14. 25 The PBSM 14 is designed such that resistance to downward movement of the member is, to whatever extent possible, minimised.
The front end 32 is narrowed to a V-shaped tip. One of the 15 most promising renewable energy sources is wave energy. As people realise that fossil fuels are a finite energy resource, the search for renewable, clean energy sources has become more urgent. This optimization is – 15 achieved by matching the performance parameters of the linear electric generator 20 to the damping requirements of the mechanical system in such a way that critical damping of the oscillating system will be achieved when the system is under full load. 20 The consequences for the survivability of the apparatus 10 are significant, not to mention the benefit of being able to produce power when other wave energy converters would have to be taken out of service to ensure their survival. A qué se debe el dolor de espalda . 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.
