The 1950s saw interest in steam-turbine cars powered by small nuclear reactors (this was also true of aircraft), but the dangers inherent in nuclear fission technology soon killed these ideas.
Na década de 1950 volveu o interese polos coches de turbina a vapor movidos por pequenos reactores nucleares (tamén para os avións), pero os perigos inherentes á tecnoloxía de fisión nuclear pronto remataron con estas ideas.
