The atomic bomb was on everyone’s mind quite a bit in the late 1940s. Clearly it was a real city-killer of a weapon, one that worked best when targeted against a dense population system. So what was America to do in the face of such a threat? Simple: spread them out and move all industry underground.
The crux of the issue was to remove everyone from any American city with a population greater than 50,000 people and place them in newly-built communities set out across the country’s landscape (mostly) like a chess board, the towns existing on all of the connecting lines. [As weird as this sounds, the great Norbert Wiener came up with a similarly astounding, untouchable idea using circles.]. The authors proposed to build 20,000,000 new homes, relocate industry (preferably underground), reallocate and redistribute energy supplies and natural resources, and recreate the very fabric of social and economic life in America.
