A Study on a Wave and Wind Energy Hybrid Conversion System --Part I: Output Characteristics of a Wave Energy Convertor Using a Ball Screw

摘要

In this paper, the authors propose a new type of wave and wind energy hybrid conversion system in order to obtain enough power to run both the navigational aids and the meteorological observations. The system is composed of a rectangular solid floating body, one or two ball screw type wave energy convertors hung from the floating body and a windmill installed on the floating body. A small-scale experimental model was made and its output characteristics were measured using a wave tank. The experimental results were compared with the calculated ones. Although the improved Savonius rotor seems to be suitable for the windmill, we will reserve the discussion about the windmill for another occasion.
