Abstract :
The energy density of wave power is higher than some other renewable energy sources such as wind and solar energy. However, because waves have an irregular reciprocating motion, it is difficult to convert wave power into electricity, and this has restricted the widespread use of wave power. In this paper, a new mechanism to convert wave power into electricity is proposed. It is referred to as a ¿direct link¿ mechanism, and consists of a buoy, rack, and a pinion. Because of its simple force transfer path, it is expected that the energy conversion efficiency is higher than usual wave power conversion systems. Experiments were carried out on a miniature model and compared to the output of numerical simulations. The results indicated that the conversion efficiency was considerably higher than conventional systems.
