NOVELTY - The device (10) has an anchor provided with a mooring chain that is connected with a floating vessel (20). An upstanding post (13) comprises a tip connected with a lever arm (12) and a foot coupled with a universal coupler. A pendulum (11) is moveably mounted on the lever arm and is erected above a platform deck (21) of the vessel by the upstanding post. A gear mechanism is incorporated with a centrifugal flywheel, and is coupled with the universal coupler through a transmission mechanism for delivery of momentum of the pendulum. A power generating mechanism is driven by the gear mechanism.    USE - Wave power generating device for serving as a buoy to provide power to a mooring ship.    ADVANTAGE - The upstanding post is distributed over the platform deck at distance from a central pivotal point of the vessel for maximum displacement of the pendulum to enhance efficiency in harnessing wave energy. The device utilizes a centrifugal flywheel system that comprises a less resistance in acceleration in comparison with traditional flywheel systems, thus assuring prompt response in acceleration with less wear and tear to mechanism for reliable performance. The vessel is provided in a shape of a segmented sphere with immersed water line aligned with a diameter of the sphere to achieve minimal water resistance as the vessel sways in undulating waves such that the vessel is applicable on freezing water surface due to water around the vessel does not freeze easily and the vessel works to a last moment till water is deadly frozen. The device is provided with simple in structure while housing the device onboard, thus providing low equipment cost, minimal maintenance and running costs, convenience in deployment, minimal impact on navigation and environment, invulnerability to stormy conditions due to simple structure, and reliable power output at times.    DETAILED DESCRIPTION - The vessel is semi-spherical in shape for larger area of contact with waves for operation in non-freezing water to harness maximum wave energy.
