Steam car

A steam car is an automobile (car) powered by a steam engine. The first automobile, a three-wheeled vehicle, was powered by a steam engine. 
History.
The steam carriage was invented in 1769 by Nicolas-Joseph Cugnot, a French engineer. It was a large three wheeled vehicle that used coal to make steam in a boiler. The boiler was mounted in front which made the vehicle unstable.
In the United States, about the time of the American Civil War, a number of inventors were working on steam-powered cars. In England about 1868 J. H. Knight had created a very successful design of steam car. In 1883 in France, Jules-Albert de Dion and Georges Bouton began building steam cars. In 1886 Ransom E. Olds was producing a steam car in the US. In 1899 the Stanley brothers, Francis and Freelan began making the famous Stanley Steamers.
Advantages and disadvantages.
Steam engines in cars have a great amount of torque. With all this torque they can accelerate very quickly. Because the torque is available over a broad range of speeds, a transmission wasn't needed. They could also carry heavy loads with ease. The speed of a steam car is controlled by the throttle alone and the engine never stalls. Steam cars had fewer moving parts than gasoline powered cars. Also steam cars are very quiet.
A major disadvantage is that a steam car has to "fire up" its boiler (has to get up to operating temperature). This can take as much as 20 minutes before the car can move. In the winter there was the added problem of water freezing. The open-cycle steam engine in cars and steam locomotives could not go far without adding water. The water turned to steam, which was lost when it exited the engine. Steam condensers were added to these cars later. This converted the steam back to water. It was too late; by then steam cars had lost out to cars with internal combustion engines.
