Abstract
Abstract A power supply of installations, especially of motor vehicles, driven by internal combustion engines which consists of a generator, a storage battery and loads as well as corresponding switching means; at least one thermionic converter acted upon by the hot exhaust gases serves as generator while at least one electric motor feeding mechanically into the drive connection of the installation is provided as load; the thermionic converter or converters as well as preferably also the storage capacity of the battery are designed as regards their power output for approximately the utilizable thermal energy of the exhaust gases of the internal combustion engine.
