The Ford Nucleon: 1958 Concept Car Powered By Nuclear Fission | Wikipedia
"The Ford Nucleon was a nuclear-powered concept car developed by Ford Motor Company in 1958. The design did not include an internal-combustion engine, rather, the vehicle was to be powered by a small nuclear reactor in the rear of the vehicle. The vehicle featured a power capsule suspended between twin booms at the rear. The capsule, which would contain a radioactive core for motive power, was designed to be easily interchangeable, according to the performance needs and the distances to be travelled." - Kurt Starnes
