Standard Steam Car

The Standard Steam Car was an American steam car manufactured from 1920 until 1921. Also known as the Scott-Newcomb, it featured a Rolls-Royce-shaped condenser and was similar in design to the Roamer. The car had a twin-cylinder horizontal steam engine and used kerosene for fuel; it was claimed to be able to raise a full head of steam within a minute. One touring car is known to have been built; the company may have produced as many as five vehicles before folding.
