The Nucleon’s design, undertaken by the aptly named Jim Powers, was dictated entirely by its power train. The cabin was crammed way out front under a giant bubble canopy — straight out of “The Jetsons,” minus the flying dog walker. The payoff for this setup was a theoretical range of over 5,000 miles on a single core. Ford pictured a world where gas stations were out, and reactor service stations were in — roll up, drop your used core, and grab a fresh one. An idea that perfectly foreshadows the battery-swapping stations of today, although storing mass quantities of nuclear cores creates its own headaches, both on local and national-security scales.
