    Abstract

    The ocean presents a vast quantity of untapped renewable energy. There exist several methods of extracting energy from the ocean waves. This system presents the concept of designing and testing a low cost wave-solar generator for Pacific Island countries. A simple self-contained wave-solar energy converter (WSEC) that can be deployed off-shore is useful in situations where there’s no supply of electricity. This device is a single unit containing all the mechanisms in an average sized barrel and placed on the surface of the sea. It operates with surging and heaving motion of the waves. The system has one moving part, gears & electric generator relative to one fixed part, the flywheel. Due to the irregular wave motions a mechanical rectifier is utilized to convert the opposing angular movements into a single directional turning alternator. For the electricity generation, a DC generator is used which provides a DC output but inconsistent power generation lead to electronic circuits being incorporated for a regulated voltage output. The design can be used in places with low wave activities as it can generate electricity with low rpm of the flywheel. All the parts for the construction of the device are readily available locally. The main purpose of this device is to provide electricity for lighting and other low powered equipment of on shore community or fisherman boat.
