Theoretically, ocean waves are composed of vertical and horizontal motions. However, only either of wave motions has been utilized in most of conventional ocean wave power generation systems, and this resulted in un-efficient conversion of ocean wave energy. The aim of this study is to propose a new system which enables more efficient energy conversion. This system loads the wave into the channel of multiple horizontal plates. Vertical and horizontal wave motions are merged in a horizontal reciprocating motion. This motion is sustained by the effect of sloshing until the next wave comes. In this research, a simple model was constructed and fundamental efficiency of this system was evaluated. As the result, it was found that more than 50% of original wave energy was converted to horizontally reciprocating motion.
