Steam CarA steam car is a car that has a steam engine. Wood, coal, ethanol, or others can be used as fuel. The fuel is burned in an oven to boil water into steam. When the water turns to steam, it expands. The expansion creates pressure. The pressure pushes the gears back and forth. The gears turn the wheels forward. It works like a coal-fueled steam train, steam cruiser (like the Titanic), or steam boat. The steam car was the next logical step in independent transport. Steam cars take longer to start, but some can reach speeds over 100 mph eventually. A steam engine uses external combustion, as opposed to internal combustion. Gasoline-powered cars are more efficient at about 25-28% efficiency. A steam engine car will work at only 5-8% efficiency. See also
