Abstract:
1. A method for generating energy from an undulating movement of a medium such as seawater, comprising the steps of: following the movement of the medium with a float, wherein a direction of movement of the movement changes at a point in time, converting the followed movement of the float into energy, and interrupting the following of the movement of the float close to said point in time, wherein the conversion of energy includes pumping a fluid with the followed movement of the float by feeding and discharging said fluid, further including regulating the movement of the float by closing the feed and/or discharge of the fluid and controlling the degree of closure of the feed and/or discharge of the fluid when the feed and/or discharge is not closed, wherein said degree of closure of the feed and/or discharge of the fluid is controlled by obtaining an acceleration signal from an accelerometer measuring the acceleration of the float and obtaining an acceleration signal from an accelerometer measuring the acceleration of the medium, and compare said two acceleration signals such that an error current is obtained, and using said error current to control said degree of closure of the feed and/or discharge of the fluid.
