Abstract From the Canadian patent

The invention provides for a floating island for producing power from waves. The floating island is comprised of columns fixed to the ocean bed,and a float interconnected to the column by gimbal mounting means. The gimbal mounting means allow the float to tilt in relation to the wave motion. The up and down motion of the float on the column in response, to the waves, is translated into power by force linking means and electrical generating means convert this power into useful electricity. Suitable force linking means may be comprised of pulley gear mechanisms, helical drive mechanisms rack, and pinion mechanism, induction mechanisms and hydraulic, mechanisms.
