Triton City, envisioned by Buckminster Fuller in the 1960s, was an early concept of a self-sustaining floating city with advanced technologies for food production, water purification, and renewable energy. The project's ambition was to create a scalable community that could expand as needed. However, it faced setbacks due to the death of its main investor, Matsutaro Shoriki, bureaucratic obstacles, and the unavailability of required technologies at the time. The Maldives Floating City, inspired by Dutch floating homes, offers a more practical approach with modular units. Despite these advancements, the long-term sustainability and viability of floating cities in the face of rising sea levels and other challenges remain uncertain.
