Abstract
It is necessary to research about development of renewable energy for energy source problems in the future. Development of wave activated generation is also one of those researches, and it is expected as the available way that obtains electric power from marine energy. However, it is severe problem how to construct the device that is available for complicated motion of wave on the sea surface, and this influences whether useful system is constructed. In this research, wave activated generator with device that linear motion of piston is changed to rotation is made experimentally, and the first measuring experiment is performed to evaluate whether our generator is practical. And we confirmed the generator indicates the performance similar to that of inspection at factory, and sufficient outputs that are expected for practical use.
