Abstract
Abstract The drive wheels of an electric automobile are driven by one or more D.C. drive motors which derive their power from a battery. The battery is charged by two separate D.C. generators. The first D.C. generator is powered by an internal combustion engine, and the second D.C. generator is powered by a steam engine. The steam engine uses waste heat from the internal combustion engine to boil its operating liquid.
