From The Secret City, one of 29 photos. Here, a special traveling exhibit of the U.S. Atomic Energy Commission, “Your Stake in the Atom”, is housed in its own geodesic exoskeleton structure some 20 feet high and 50 feet in diameter in Oak Ridge, Tennessee, in 1966. The exhibit featured live demos on uses of nuclear power and a set of remote controlled mechanical hands. (Ed Westcott/DOE)
