Buckminster Fuller's 1962 Floating City Vision and the Enduring Quest for Architectural Levitation

In 1962, architect Buckminster Fuller envisioned a floating city composed of enormous aerial geodesic spheres called Cloud Nine, designed to levitate naturally using sun-heated warm air and anchored to mountaintops. This hypothetical project aimed to house thousands, addressing land ownership politics, housing shortages, and nature preservation. Over half a century later, achieving truly floating structures on Earth remains an unattained ideal, with supports still necessary despite manipulations in their position, intensity, and quantity to approach defying gravity. The desire to overcome gravity continues to fascinate humanity, as seen in contemporary architectural explorations like the Museu de Arte Zaishui by junya ishigami + associates, though Fuller's specific vision remains unrealized.
