Abstract
A power-take-off system for use in a wave energy converter buoy employs a meshing nut and screw shaft assembly for motion conversion. That is, the motion of the buoy float is coupled to drive the nut along the screw shaft on which it is mounted. The linear movement of the nut along the shaft causes the shaft to rotate and this rotational motion is then coupled to rotate an electrical generator.
