The Atomic Automobile

The late 1950s were an optimistic era. Witness The Atomic Automobile, Ford’s Nucleon concept car from 1957:

Ford’s engineers imagined a world in which full-service recharging stations would one day supplant petroleum fuel stations, where depleted reactors could be swapped out for fresh ones lickety-split. The car’s reactor setup was essentially the same as a nuclear submarine’s, but miniaturized for automobile use. It was designed to use uranium fission to heat a steam generator, rapidly converting stored water into high-pressure steam which could then be used to drive a set of turbines. One steam turbine would provide the torque to propel the car while another would drive an electrical generator. Steam would then be condensed back into water in a cooling loop, and sent back to the steam generator to be reused. Such a closed system would allow the reactor to produce power as long as fissile material remained.

Using this system, designers anticipated that a typical Nucleon would travel about 5,000 miles per charge. Because the powerplant was an interchangeable component, owners would have the freedom to select a reactor configuration based on their personal needs, ranging anywhere from a souped-up uranium guzzler to a low-torque, high-mileage version.

The vehicle’s aerodynamic styling, one-piece windshield, and dual tail fins (which are absent in some photographs) are reminiscent of spacecraft from 1950s-era science fiction, but some aspects of the Nucleon’s unique design were more utilitarian. For instance, its passenger area was situated quite close to the front of the chassis, extending beyond the front axle. This arrangement was meant to distance the passengers from the atomic pile in the rear, and to provide maximum axle support to the heavy equipment and its attendant shielding. Another practical design aspect was the addition of air intakes at the leading edge of the roof and at the base of the roof supports, apparently to be used as part of the reactor’s cooling system.

Ford’s nuclear automobile embodied the naive optimism of the era.
