Ford Nucleon

It sounds like a nuclear experiment, and funnily enough, thats exactly what the Ford Nucleon was. Although it was just a scale model, Ford wanted to show that you could in theory, based on scientific knowledge at the time, power a car with steam and uranium fission.

Ignoring the safety issues of crashing in a mobile nuclear bomb, the Ford Nucleon wasnt such a mad idea given that nuclear power is relatively clean ? well, except for the glowing green waste. Probably why Bethesda designers decided to include the car in the nuclearscarred landscapes of Fallout 3.
