Fuller Visionary Proposals: Geoscope, Cloud Nine, and Old Man River's City
Consolidated research compilation on three of Buckminster Fuller's most ambitious unbuilt proposals, drawn from BFI archives, Wikipedia, and History and Headlines.
Geoscope
The Geoscope was Fuller's proposal for a 200-foot diameter geodesic sphere to be suspended above the East River near the United Nations headquarters by a tetrahedral mast, first articulated around 1960. A larger 400-foot version was later proposed for Southern Illinois University Edwardsville (SIUE). The sphere's surface would be covered in millions of computer-controlled colored miniature electric light bulbs, allowing real-time display of global data including resource inventories, population distributions, geological changes, migration patterns, and weather systems. Fuller described the structure as "structurally gossamer" in its geodesic frame.
The concept had several precursors. In 1952, Fuller and students including Shoji Sadao built a 20-foot "Miniature Earth" at Cornell University. Additional models were constructed at the University of Minnesota and Princeton between 1954 and 1956. The 5/8th spherical design was deliberate: from inside, a viewer could see approximately 5/8ths of Earth's surface simultaneously, compared to only about 1/3 visible from outside a full sphere.
The Geoscope was directly integrated with Fuller's World Game concept as its primary visualization environment. Computers would store "all relevant inventories of world data arranged chronologically," enabling playback at variable speeds to project 50-year trends. Fuller wrote in Critical Path (1981): "This 200-foot-size Geoscope would make it possible for humans to identify the true scale of themselves." In Education Automation (1962), he added: "With the Geoscope humanity would be able to recognize formerly invisible patterns."
Key collaborators included Shoji Sadao, James Fitzgibbon, Duncan Stuart, Don Richter, Jeffrey Lindsay, Thomas Turner, and John McHale. A functional 40-foot dome was built at SIUE in 1971 by Fuller and Sadao.
The Geoscope's conceptual ancestor was the "Conning Tower" (1932), a multimedia environment Fuller envisioned for global information access. Modern parallels include Google Earth (digital globe) and the Las Vegas Sphere (immersive display on a geodesic structure).
Cloud Nine
Cloud Nine was Fuller's proposal for mile-wide geodesic spheres that would float freely in the atmosphere, designed circa 1960 with collaborator Shoji Sadao under the name "Project for Floating Cloud Structures."
The physics relied on a fundamental scaling property of geodesic spheres: as the sphere scales up, enclosed volume grows as the cube of the radius while structural mass grows roughly as the square. At mile-wide scale, the structural mass becomes negligible compared to the enclosed air mass. From Fuller's own tensegrity essay, a sphere 1.125 miles in diameter would weigh approximately 56,000 tons in structure but enclose roughly 5 million tons of air -- making the structural weight approximately 1% of the enclosed air mass. Heating the interior air just one degree Fahrenheit above the ambient outside temperature would generate enough buoyancy to lift the entire structure.
Intended uses included tethered or free-floating habitats, migratory settlements that could respond to climate and environmental conditions, and emergency shelters capable of housing thousands of people. No Cloud Nine was ever built; the concept remains a thought experiment demonstrating the extraordinary scaling properties of geodesic geometry. It inspired Eric Vinicoff's 1988 science fiction novel Maiden Flight, which featured "windriders" based on the Cloud Nine concept.
Old Man River's City
Old Man River's City was Fuller's proposal for a domed city to be built in East St. Louis, Illinois, unveiled in late 1971. The design was a circular, moon-crater-shaped, terraced cone under a geodesic dome -- explicitly not tetrahedral.
The structure's dimensions: one-mile base diameter, half-mile rim-to-rim dome, 1,000-foot dome height, 500-foot rim height, with the interior descending 500 feet below the rim. The design featured 50 inward-sloping terraces for communal life and 50 outward-sloping tree-planted terraces for private dwellings, each terrace separated by 10 feet vertically. A transparent quarter-sphere umbrella dome would allow unobstructed sky views. The plan provided 2,500 square feet per family and a total capacity of 125,000 occupants.
Katherine Dunham, a world-class dancer who had retired to East St. Louis, was the key advocate who connected Fuller to the community. Both Dunham and Fuller taught at Southern Illinois University. However, community response was skeptical: residents told Fuller, "We don't need domes, we need jobs." Fuller responded with utopian rhetoric about a post-employment future that failed to convince many residents.
Attorney Wyvetter Younge, who became a state House Representative from 1974, introduced supporting legislation annually in the Illinois General Assembly until her death in 2008. The legislation never passed. Republican legislators mocked the proposal as the "solar rib pit." The estimated cost was $700 million in 1971 dollars, with no identified funding source. East St. Louis's population declined from approximately 70,000 to under 27,000 over subsequent decades, and the supporting nonprofit eventually dissolved quietly.
