Abstract: An inflatable structure for gas storage (such as carbon dioxide) includes an inner bladder containing a gas for storage and an outer wall spaced from the inner bladder. An intermediate space between the bladder and the outer wall is pressurized with a gas other than the storage gas (such as air) so that the structure is protected from environmental conditions such as wind and snow loading. A method of using the inflatable structure for storage of a storage gas includes using a blower to inflate the inner bladder with storage gas, and pressurizing the intermediate space with air to have a higher pressure than the inner bladder.

The bladder and outer wall may be flexible fabric membranes and may be provided with lightweight support frames. The structures may be combined in a network of like structures for large scale storage.

Abstract: An inflatable hangar for an airship is provided with retractable support frames so that the structure retains sufficient shape when the structure is opened and deflated to permit entrance and exit of an airship. The inflatable structure is thus easily re-inflated. The resulting membrane structure is transportable and cost-effective.

Abstract: The present invention discloses a portable, erectile, collapsible storage bin for flowable dry materials, the bin being formed of a flexible, moisture-proof membrane which, when inflated, defines a closed volume having openings for both in-flow and out-flow of material. Said membrane exhibits a conical portion in which said in-flow opening occupies the apex of said cone. There is thus provided a plurality of rigid poles having a height of between two and eight feet, each pole disposed normally to the plane of the ground, each pole equidistantly disposed from each adjacent pole in a circle defined by one radius from the axis of symmetry of said cone. The poles are secured exteriorly to said membrane in order to form thereof an essentially polygonal surface normal to the plane of the ground.
