All kind of devices to generate power from ocean waves have been thought and invented,
the list is to big and it is bigger if we consider all variations possible to these
basic system, in this section we will take a short review of the pendulum type, this
type can accommodates a large number of different versions and the possibilities
to connect it to any other conceivable power generation device is immense, only limited
by the system designer imagination.
Pendulum With Compressor
The figure below illustrates a possible configuration for a waves energy generator
in which a floating tank is attached to an arm and then this is fixed to a pole
structure that supports the complete system, the reciprocating compressor can be
attached in the front side of the arm or can be connected in the back. The efficiency
of the system will depends on a care full system design and the proper ocean location,
as in any other waves energy generation system the bigger the amplitude and the period
regularity of waves are essential for the successes of the project. Due to the multiple
possibilities no details on how a compressor works are explained here.
Pendulum With Flywheel Gears
This system uses the same pendulum principle to convert the oscillating energy of
the waves into rotational movement, it uses a floater attached to an arm connected
to a flywheel that turns
as the ocean waves, this flywheel translates this partial rotary movement to a full
360 degrees or more, from here any other device can be connected to an electrical
generator or any mechanism.
The floater can be made to turn freely or fix, but freely rotation could be better
in reducing the pressure exerted by the floater over the structure and to improve
the overall efficiency.
