Abstract
In order to get low cost electricity, the offshore Pendulor of large scale had been studied by Muroran I.T. This idea was transferred to the OWC wave converter to improve it on the saving cost by multiplying with OWC and Pendulor. We named it New OWC which is simple and robust same as the OWC and highly efficient like as the Pendulor. The principle of the New OWC is shown here and a 1/25 scale model of it was made for the experimental study with a 2D wave tank. The test could come to no goal but it clarified fundamental characteristics of the New OWC for future investigations.
