In this study, the electrical generator is developed to generate electricity in the Tsugaru Strait. However, the Tsugaru Strait has little quantity of generation because speed is slow. Because so I applied a wind lens technology and intended to let you rise speed. We devised Brimmed diffuser for tidal generation with integrated water turbine and power generation section supported by circumference. The purpose of this study is to find out whether Examination of the circumference support method of the lens waterwheel for tide generation. Therefore I thought that It is an axis cost cut, a seal-free, and there is no tip clearance.
