Geodesic dome with false starts and incorrect estimates. Fuller himself lived in a geodesic dome in Carbondale, Illinois, at the corner of Forest Ave and Cherry St. Fuller thought of residential domes as air-deliverable products manufactured by an aerospace-like industry. Fuller's own dome home still exists, the R. Buckminster Fuller and Anne Hewlett Dome Home, and a group called RBF Dome NFP is attempting to restore the dome and have it registered as a National Historic Landmark. It is on the National Register of Historic Places. In 1986, a patent for a dome construction technique involving polystyrene triangles laminated to reinforced concrete
Geodesic dome resists sun and weathering. Some form of internal flashing or caulking must be placed over the joints to prevent drafts. The 1963 Cinerama Dome was built from precast concrete hexagons and pentagons. Given the complicated geometry of the geodesic dome, dome builders rely on tables of strut lengths, or "chord factors". In "Geodesic Math and How to Use It", Hugh Kenner writes, "Tables of chord factors, containing as they do the essential design information for spherical systems, were for many years guarded like military secrets. As late as 1966, some 3"ν" icosa figures from "Popular Science Monthly" were all anyone
