During the 1950s, much of the world was quivering with anticipation over the exciting prospects of nuclear power. Atomic energy promised to churn out clean, safe electricity that would be “too cheap to meter.” It seemed that there was no energy problem too large or too small for the might atom to tackle during the glorious and modern atomic age.
It was during this honeymoon with nuclear energy, in 1957, that the Ford Motor Company unveiled the most ambitious project in its history: a vehicle design that had a sleek futuristic look, emitted no harmful vapors, and offered incredible fuel mileage far beyond that of the most efficient cars ever built. This automobile of the future was called the Ford Nucleon, named for its highly unique design feature: an ultra-compact atomic fission reactor in the trunk.
Ford imagined a world in which full-service recharging stations would one day supplant petroleum fuel stations and where a depleted reactor could be swapped out for a fresh one lickety-splits. The company’s automotive engineer intended to use a reactor modeled after those found in nuclear submarines, but miniaturized for automobile use. It would use uranium fission to heat a steam generator, rapidly converting stored water into high-pressure steam that could then be used to drive a set of turbines. One turbine would provide the torque to propel the car while another would drive an electrical generator. Steam would then be condensed 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 power plant 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. And without the noisy internal combustion and exhaust of conventional cars, the Nucleon would be relatively quiet, emitting little more than a turbine whine.
The vehicle’s aerodynamic styling, one-piece windshield, and dual tail fins (which were absent in some photographs) are reminiscent of spacecraft from the 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 chassis, extending beyond the front axle. This arrangement was meant to distance the passengers from the atomic power plant 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 the 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.
Perhaps more than any other atomic-era aspirations, Ford’s nuclear automobile embodied the naive optimism of the era. Most people were ignorant of the dangers of the atomic contraption and of the risk that every minor fender-bender could have the potential to become a radioactive disaster. In fact, the public greeted the Nucleon concept with great enthusiasm. Some sources even claim that the U.S. government sponsored Ford’s atomic car research program.
The Nucleon’s silent, sleek, and efficient design seemed poised to secure its place in the American lifestyle of the future. It appeared inevitable that the internal combustion engine would fade into obscurity, becoming a quaint relic of a pre-atomic past. But the Nucleon’s design hinged on the assumption that sufficiently small nuclear reactors would be developed, as well as lighter shielding materials. When those innovations failed to appear, the project was scrapped due to conspicuous impracticality; the bulky apparatus and heavy lead shielding didn’t allow for a safe an efficient car-sized package. Moreover, as the general public became increasingly aware of the dangers of atomic energy and the problem of nuclear waste, the thought of radioactive “automobiles” zipping around town lost much of its appeal. Atoms had broken their promise. The honeymoon was over.
Ford never actually produced a fission-powered prototype, but nevertheless the sleek Nucleon remains an icon of the atomic age. In spite of the Nucleon’s flaws, its designers deserve a nod for their slap-dash ingenuity. Their reckless confidence demonstrates that one shouldn’t consider a task impossible just because nobody has tried it yet – some ideas need to be debunked on their own merit.
With today’s looming energy crisis and slow migration to alternative fuel sources, we may not have seen the last of this automobile concept. A safe atomic vehicle may not be beyond our reach, as the U.S. Navy has demonstrated with its (so far) perfect record of nuclear safety. Perhaps one day fossil fuels will wither under the radioactive glare of the mighty atom and our highways will hum with the steam turbines of mobile Chernobyls. It would be a real blast.
