From a design engineers perspective geodesic domes are far superior to traditional
right angle post and beam construction techniques, which are far less efficient, far heavier, inherently instable, and rely on gravity to stand up.
Much of the inspiration for the idea of creating a latticework as internal trusses comes from natural geodesic structures in living
organisms. The living cells use a form of geodesic architecture to organize their molecular scaffolds into porous three-dimensional forms that simultaneously provide high mechanical strength and enhanced flexibility.
The word “Tensegrity” is a contraction of tensional integrity. Tensegrity describes a structural-relationship principle, in which a system stabilizes itself mechanically because of the way in which tensional and compressive forces are distributed and balanced within the structure.
The geodesic dome combines the sphere, the most efficient container of volume per square foot, with
the tetrahedron, which provides the greatest strength for the least volume of weight. A geodesic dome is an almost spherical structure based on a network of struts arranged on great circles (geodesics) lying on the surface of a sphere. The geodesics intersect to form triangular elements that create local triangular rigidity and distribute the stress. Geodesic domes are far stronger as units than the individual struts would suggest.
