The study about using fluid flow to generate electricity

The power source is necessary for underwater devices operating independently. The various machinery and tools such as underwater vehicles or observation buoys are developed to collect data. The underwater power source is one of very important device to operate these machinery and tools for a long time. Many research and development about the underwater power source is performed. Various methods to store electricity are researched and developed for underwater power source for mainly. In this paper, It is studied a method to generate electricity using fluid flow. The paper reported that estimated results about using water flow to generate electricity and fundamental experimental results.
