Buckminster Fuller imagined this tetrahedron city project for Tokyo’s bay. He also imagined a similar floating tetrahedral city for San Francisco’s Bay.

 From MoMA’s website:

The buoyant metropolis was designed to accommodate one million citizens in 300,000 apartment units, and it even includes a huge interior harbor. Fuller, who spent his career searching for “ever higher performance with ever less investment of material resources,” envisioned Tetrahedron City as an efficient response to two major problems of architecture and urban planning: construction costs and land acquisition.

What do you think: would you consider living in one of these floating cities, had Buckminster Fuller’s utopian vision come to fruition?
