It is easy to visualize the energy in a wave when you are sitting in a small boat in rough water or even standing on the shoreline observing. The rise and fall of the waves is a steady expenditure of kinetic energy. Generating electricity from water as pours in a controlled water over a wheel that turns a turbine and thus the generator is something we learned to do 100 years ago. Generating usable electricity from the rise and fall of random waves in the ocean is another story all together. The answer is the linear power generator.
It is estimated, that there could be theoretically obtained from 100 to 200 megawatts of energy in one rolling sea coast’s kilometer, it means that moderately- 5 kW/m2.
That to make it easier to imagine what amount of energy it is, we could compare it with wind energy. From the wind we could get about 0,7 kW/m2 of energy.
However, it is difficult process to create an effective mechanism, which would change wave’s energy into electricity.
One of the most aggravating factors of this process is the linear movement of the wave conversion to rotational. This is why longitudinal movement generator was invented. On purpose, that it would work, there is necessary linear movement instead rotational. Meanwhile, surge gives exactly movement, which is necessary. This generator solves the problem of complicated mechanical constructions. This is one more step towards appliance of wave’s energy.
