Project PACER, carried out at Los Alamos National Laboratory in the mid-1970s, explored the possibility of a fusion power system that would involve exploding small hydrogen bombs —or, as stated in a later proposal, fission bombs—inside an underground cavity. As an energy source, the system is the only fusion power system that could be demonstrated to work using existing technology. However it would also require a large, continuous supply of nuclear bombs. The earliest references to the use of nuclear explosions for power generation date to a meeting called by Edward Teller in 1957. Among the many topics covered, the group considered power generation by exploding 1 Mt bombs in a 1,000-foot diameter steam-filled cavity dug in granite. This led to the realization that the fissile material from the fission sections of the bombs, the "primaries", would accumulate in the chamber. Even at this early stage, physicist John Nuckolls became interested in designs of very small bombs, and ones with no fission primary at all. This work would later lead to his development of the inertial fusion energy concept.
