Abstract

Currently, many ships or underwater vehicles use ballast to control their buoyancy, although it is harmful to the environment. We have been developing a volume variable buoyancy control device inspired by a hypothesis on the volume control mechanism of sperm whales. We proposed several mechanisms and achieved the depth control using one of the mechanisms. As the next step of this study, we focus on waste heat of ships. Usually large ships adopt a co-generation system, in which heat are wasted. Because our proposed mechanism needs a large amount of heat, we consider that our mechanism works well in the system. First, we manufactured a prototype mechanism utilizing stretch of rubber sheet. Its shape is a cylinder, in which heated water flows. Also, we built a prototype system composed of a pump, a thermostat chamber and volume valuable mechanism, and investigated the system through an experiment.
