<p>A wave energy converter (WEC) having an asymmetrically shaped float and a spar which move relative to each other in response to the waves. The asymmetrical float has one side longer than the other. A power take off device (PTO) is coupled between the asymmetric float and the spar for converting their relative motion into useful power. Apparatus is coupled to the WEC for: (a) orienting and rotating the longer side of the float to face and receive oncoming waves to increase energy capture when the waves have an amplitude below a predetermined value for improving the power generation of the WEC; and (b) rotating the float to orient the narrower side of the float to face and receive the incoming waves when the waves have an amplitude above a predetermined value, so as to reduce the forces to which the WEC is subjected. There is no known WEC system with an asymmetrical float which is raised and lowered by the waves.</p> |
