Many of the homes were B-1 Flat Tops, a design fashioned from prefabricated panels and roofing to save construction time.32 billion (about $18.5 billion in today’s dollars). Then came trainloads full of construction equipment and building materials. Some are used on rugged construction sites and lift heavy materials and equipment while other forklifts drive themselves inside modernized warehouses. In 1917 the Clark Company, manufacturers of axles, created a truck called the Tructractor to move materials around their factory. To solve that problem, the Clinton Engineer Works’ Y-12 plant used special devices called calutrons, which utilized the electromagnetic separation process developed by Nobel-winning physicist Ernest O. Laurence at the University of California, Berkeley. Even so, to gather enough uranium-235, the Y-12 facility employed 22,000 workers to run 1,152 calutrons literally around the clock. Another portion became the Y-12 National Security Complex, which produced components for tens of thousands of thermonuclear weapons in the U.S. But that would require a massive, complex manufacturing process, involving tens of thousands of workers, which needed to be kept secret to thwart interference from spies and saboteurs. Finally, on Aug. 6, 1945, the world got to see the results of the secret city’s labors, when an atomic bomb containing uranium-235 produced there was dropped on the Japanese city of Hiroshima.

Locals knew that something mysterious was going on at the site, but only those who were part of the mission were allowed inside, past the guarded gates on the access roads. Those who turned down jobs might end up being drafted into a special engineering detachment of the U.S. Manhattan Project, who scoured the campuses of U.S. But for the early settlers who built structures like the Peralta Adobe, the material was as much about convenience as energy efficiency.
