High efficiency wave energy convertor

摘要

The present invention is related to wave energy convertors (WECs). Such devices are used to convert energy contained in the wave motion of water into useful electrical energy. According to the present invention, a WEC is provided that comprises:
- a buoy;
- a stabilization body for providing a stabilized anchoring platform for said buoy;
- a cable connecting said buoy to said stabilization body, said cable connected to a cable winch to allow for a varying length of cable in between said buoy and said stabilization body;
- energy generating means to generate energy comprising a damping element to exert a damping force on said cable;
wherein said energy generation is based on work done to overcome said damping force.
