Abstract
A new type wave power generation system is proposed to be installed in a vertical slit type breakwater. The merits of the system are listed as follows, (i) no occupation of the sea surface, (ii) maintenance facility, and (iii) high energy efficiency by using accelerated flow from the slit of breakwater. In this study, several kinds of water wheels were examined to be installed in a model wave breaker with 1/12 scale ratio to the actual system. The experimental results show that the crossflow type has a higher performance. Ina addition, a bending plate type generator was examined to achieve higher efficiency. When the elastic plate is bent by the drag of wave, a tension appears and a wheel and axle is rotated. The performance of bending plate generator is examined under various experimental conditions. The output per occupied sea area is expected as 23,500(W/m^2) in the real system.
