Development of Ocean Current Power Generation Equipment as Learning Materials

Abstract

The purpose of this study is to develop teaching materials and teaching tools for raising the ability to think and judge scientifically and to evaluate and utilize them, while encouraging the understanding according to the developmental stage, taking energy situation and environmental problem of Japan and the world which are tense recently as a subject. In this study, the development of the ocean current power generation equipment is proposed with the aim of scientifically recognizing the necessity of the introduction of the renewable energy and technical problems in proportion to the developmental stage, and acquiring the ability to appropriately evaluate and utilize the technology. The developed equipment is composed of a hull and a power generation turbine. On the hull, the hull stabilization is attempted by arranging two floats made of foamed polystyrene side by side. The turbine was designed by 3D CAD and fabricated by 3D printer. Created. On the power generation turbine, after the students themselves designed it using simple 3DCAD and printed it by 3D printer, they intend to improve it so that it becomes more efficient through experiment and measurement in this experimental equipment.
