It is a long surface buoy cylinder that is lifted by each passing wave.
As the cylinder is lifted, it pulls on its anchor lines, which, in turn, pulls on a support pulley. This support pulley turns the generator’s
rotor and flywheel.
The generator’s flywheel keeps the rotor turning until the next wave lifts up the cylinder and the anchor line once again turns the pulley.
The cylinder will also be lifted by waves from all directions. As a result, the anchor cables at each end of the buoy may either pull
together or at slightly different times.
The gears, the pulleys, the rotor and flywheel are turned when the anchor cable’s tension is high.
The uni-direction pulley’s re-coil spring re-winds the anchor cable back around the pulley, when the buoy moves down with the trough of
the wave and the anchor cable tension is low.
The wave generator can be in a surface buoy or mounted sub-surface.
The combination of several wave generators (and current generators) can be made into an offshore ‘power farm’.
