Spherical enclosure suitable as a building structure, pressure vessel, vacuum vessel, or for storing liquids
First Claim
1. A spherical dodecahedral enclosure comprised of:
- A). 6 bands of airtight material, woven together to form a sphere with 12 pentagonal openings and 20 places where 3 bands intersect. B). 12 covers suitably shaped to cover the 12 pentagonal openings, and attached in such a way as to form an airtight seal. C). 20 intersections of said enclosure to be covered and or sealed in such a way as to form an airtight seal. D). All other seams of said enclosure to be sealed in such a way as to make the said enclosure, airtight.

Abstract
A spherical container having a shell formed by 6 bands, interwoven in such a way as to create 12 pentagonal openings spaced evenly around the sphere. 12 pentagonal covers, 20 disk shaped covers, and 30 struts. Building materials for the invention can be composite materials such as graphite or fiberglass fibers wherein, the parts are joined with stitching and then permanently bonded together with a suitable adhesive such as epoxy to form an airtight container. The invention can also be fashioned from sheets of weldable material, wherein all seams are welded together to form an airtight container. The 30 struts are placed inside the sphere with their end points located with reference to the vertexes of the pentagonal openings in such a way as to form a tensegrity dodecahedron. This structure may be used as a building, a pressure vessel, a vacuum vessel, or a container.

4. The novel combination of an internal or external dodecahedral frame work with any spherical structure in such a way that the said framework is applied to the spherical structure so as to play the part of the compression elements of a tensegrity dodecahedron while allowing the surface of the sphere to play the part of the tension members, (formerly cables of some sort), of the same tensegrity dodecahedron.

5. The novel combination of the spherical dodecahedron with the tensegrity dodecahedron in which the 60 vertexes of the pentagonal openings are used to quickly and easily locate the points of attachment for the 30 required struts.
