Wave Energy System


Wave Energy System

Wave power varies considerably in different parts of the world. Areas of the world with abundant wave power resource include the western coasts of Scotland, northern Canada, southern Africa, Australia, and the northwestern coast of the United States, particularly Alaska.

According to studies throughout history on this renewable energy, it is known that the amount of energy you can get from it, is proportional to the period of oscillation of the waves, like the square of the amplitude of these. For this reason it is known that such features are in maritime areas with depths between 40 and 100 meters. Depending on the depth of installation of the devices used for this purpose you can be classified into:
  • on-shore
  • near-shore
  • off-shore
It is floating devices, inside of them is a piston-like structure that when a wave crunches it moves up and down, generating mechanical movement; below the piston is a magnetic shaft, so when a mechanical movement is produced and a magnetic flow is there, an electrical flow is produced, according to Lenz law. So this electrical energy is transfered by the magnetic shaft attached to the floor and it's sent to the shore by an underwater cable.
