Abstract
Abstract A firebox, steam boiler and steam condenser are mounted in a road vehicle such as a passenger automobile. A steam powered drive member, such as a steam turbine, is operated by the steam pressure from the boiler and has drive connection with the drive axle of the vehicle. The vehicle carries a fuel bin for holding a supply of powdered fuel which is fed to the firebox. An electrical system is also associated with the vehicle to produce an auxiliary heating function for the boiler, and such electrical system includes a time control arranged to energize the heating element at a preset time. A temperature control is also provided. A water supply system for the boiler includes an auxiliary condenser to assist the main condenser in the system. Main and auxiliary reservoirs are provided to facilitate adequate storage of water in a compact arrangement.
