<p>PROBLEM TO BE SOLVED: To solve the problem where a floating unit inflated by a light gas can be not kept on floating for a long time because of the hourly leakage of the light gas. SOLUTION: A floating unit made from a film, material and inflated by a light gas is moored by mooring ropes, and a light gas is supplied into the floating unit through a gas introducing tube laid along the mooring rope to solve the problem of a buoyancy shortage caused by the leakage of the light gas in the floating unit. Further, photovoltaic cells or photocollectors are stuck to the surface of the floating unit to generate an electric power or receive a sunlight efficiently.</p> |
