Abstract

The proposed invention captures and converts the energy available in ocean waves into any usable form of energy. To complete the conversion the entire system works in two stages, the first stage captures up and down motion of wave surface into alternative mechanical rotation and the second converts this alternative rotation into continuous rotation with no significant loss in transmitted energy. This captured and converted energy in the form of mechanical rotation could be used for further utilization. The wave harnessing is done in first stage which comprising a Central Body (1) and balancing weight (2) assembly which oscillates along up and down motion of waves and produces an alternative mechanical rotation at the input shaft (3). The second stage of conversion is responsible for converting captured energy in the form of alternative rotation at shaft (3) into continuous rotation by a unique gearbox called Unidirectional Gearbox. This unidirectional gearbox is capable of converting any clockwise or anti-clockwise directional rotation at its input shaft into continuous unidirectional rotation at its output shaft. This process happens with no significant energy loss. In the over all assembly, the central body assembly is coupled with a shaft (3) and this shaft is coupled with the input shaft of said unidirectional gearbox. The output (Continuous unidirectional rotation) of the Unidirectional Gearbox could be utilized for any purpose; in this case the output shaft is connected with an electric generator.
