Abstract
A wave energy conversion device including a first pontoon configured to respond to an incident wave by operating in at least a first mode of motion and a second pontoon movably attached to the first pontoon by attachment means and configured to respond to an incident wave by operating in at least one mode of motion different from the first mode of motion. The relative motion of the first pontoon to the second pontoon in response to an incident wave is converted into a desired form of energy.
Claims20
A wave energy conversion device for use in a body of water, comprising:
- a first pontoon configured to respond to an incident wave by operating in at least a first mode of motion;
- a second pontoon movably attached to the first pontoon by an attachment arrangement and configured to respond to an incident wave by operating in at least one second mode of motion different from the first mode of motion;
- wherein a relative motion of the first pontoon to the second pontoon in response to an incident wave is converted into a desired form of energy;
- wherein the first pontoon and the second pontoon each comprise an elongate body, wherein the second pontoon is attached to the first pontoon at a midpoint of an elongate axis of the first pontoon, and an elongate axis of the second pontoon is traverse to the elongate axis of the first pontoon;
- and
- wherein the second pontoon has a surface area greater than a surface area of the first pontoon, and a dimension of the second pontoon along its elongate axis which is located transverse to the elongate axis of the first pontoon is greater than a dimension of the first pontoon in a direction transverse to its elongate axis.
