Abstract: This invention relates to a wave energy conversion system designed to convert ocean wave motion into electrical energy. The system includes a buoyant structure configured to move in response to wave-induced forces and a guidance mechanism configured to control the motion of the buoyant structure along a predetermined path. Mechanical energy generated by the buoyant motion is transferred through a motion transmission system capable of converting oscillatory or linear movement into rotational or usable mechanical energy. The transmission system may include mechanisms such as gear systems, timing belts, rack-and-pinion assemblies, screw drives, chain drives, or equivalent motion conversion mechanisms. The system may further incorporate energy conditioning components including inertia- enhancing mechanisms and adaptive stiffness elements configured to regulate and stabilize energy transfer under varying wave conditions. The invention provides a scalable and mechanically robust solution for harvesting renewable energy from ocean waves. Abstract: ar b s t r a c t : a r b s t r a c t : a r ar a r a r
