By the year 2030, the Department of Energy of the Philippines anticipates the country’s demand for electricity to hit 70% more than its current capacity. In order to reach this goal, developments on current renewable energy systems should be increased since it only constitutes 25% of the current capacity. In this paper, a prototype power-buoy system consisting of permanent-magnet DC motors, a rack- pinion gear system, and a rectifier circuit was developed to utilize wave power as a source of renewable energy. The prototype also consists of power and motion measuring devices to characterize the wave and the buoy to determine its efficiency. Based on the results, the prototype showed a mechanical conversion efficiency of 37% and an electrical conversion efficiency of 15%.
