In 2025, it is predicted that about 5 billions of people all over the world will face water shortage. In the case of Japan, on the other hand, it is thought that there are enough water resources in Japan. However, water is necessary not only for our daily life but also for the agricultural use. Considering these facts, it have come to clear that Japan actually imports a lot of water, about half of the needs. Therefore, effective uses of water resources are studied for the isolated islands such as Sakishima island, Okinawa, where water supply is almost constantly in iill-condition.
Water resources are transported to the water-shortage isolated islands from other area where rhere are enough water by the use of MEGA-BAG made of fiber-reinforced rubber and stored in reservoir there.
This constant supply of water resources would encourage the agricultural economy in this area.
The possibility for the generation of electricity by the use of wind force and biomass was also examined.
The keys technology for this study is the optimum design and manufacture of rubber materials.
