Tidal and ocean current power generation effectively enable us to supply a kind of renewable energy with relatively small turbine diameter in compared to wind turbine thanks to sea water density which is more than 800 times of that for atmosphere. In the present study, one focuses on tidal and ocean power system together with the viewpoints on ocean, ship/port, railway/bridge, electronics and machinery, and energy materials. Then, operation tests are designed for coastal, islands and inland sea to obtain a suitable energy recovery system. A small-sized demonstrator, which is composed of a vital part of novel, compact and efficient rotating machine concepts, was designed and assembled together.

由于海水密度是大气密度的800倍以上，潮汐和洋流发电有效地使我们能够提供一种与风力涡轮机相比涡轮直径相对较小的可再生能源。在本研究中，重点关注潮汐和海洋发电系统，并结合海洋、船舶/港口、铁路/桥梁、电子和机械、能源材料等方面的观点。然后针对沿海、岛屿和内海设计运行试验，以获得合适的能量回收系统。一个小型演示器由新颖、紧凑和高效的旋转机器概念的重要部分组成，并被设计和组装在一起。
