If electromagnetic (EM) rail guns are to be used to propel substantial projectiles, large amounts of energy must be delivered in a fast, high-current pulse. Homopolar genenerators (HPGs) store megajoules (MJ) of energy in the inertia of a flywheel and then electromagnetically convert this energy into megampere (MA) current pulses that typically have a duration between a thousandth of a second and a second. These machines appear to be the most likely power supply for military rail guns, space launchers, and other large EM propulsion schemes. However, HPGs now exist only as large prototype fixed installations. In order to serve as field power supplies, HPGs must be suitable designed for production, have reduced auxiliary requirements, and generate more power and store more energy per unit mass than the present generation of HPGs.
