restriction is the need to supply feedwater to the boiler. This must either be carried and frequently replenished, or the car must also be fitted with a condenser, a further weight and inconvenience. Steam-powered and electric cars outsold gasoline-powered cars in the US prior to the invention of the electric starter, since internal combustion cars relied on a hand crank to start the engine, which was difficult and occasionally dangerous to use, as improper cranking could cause a backfire capable of breaking the arm of the operator. Electric cars were popular to some extent, but had a short range, and could not be charged on the road if the batteries ran low. Once working pressure was attained, early steam cars could be instantly driven off with high acceleration, but they typically take several minutes to start from cold, plus time to get the burner to operating temperature. To overcome this, development has been directed toward flash boilers, which heat a much smaller quantity of water to get the vehicle started, and in the case of Doble cars, spark ignition diesel burners. The steam car does have advantages over internal combustion-powered cars, although most of these are now less important than in the early 20th century. The engine (excluding the boiler) is smaller and lighter than an internal combustion engine. It is also better-suited to the speed and torque characteristics of the axle, thus avoiding the need for the heavy and complex transmission required for an internal combustion engine. The steam car is also quieter, even without a silencer. History Early history The first steam-powered vehicle was supposedly built in 1679 by Ferdinand Verbiest, a Flemish Jesuit in China. The vehicle was a toy for the Chinese Emperor. While not intended to carry passengers and therefore not exactly a car but a carriage, Verbiest's device is likely to be the first ever engine powered vehicle. Also it seems that the Belgian vehicle served as an inspiration for the Italian Grimaldi (early 1700) and the French Nolet (1748) steam carriage successor. A French inventor, Nicolas-Joseph Cugnot, built the first working self-propelled land based mechanical vehicle in two versions, one in 1769 and one in 1771 for use by the French Army. William Murdoch built and operated a steam carriage in model form in 1784. In 1791 he built a larger steam carriage which he had to abandon to do other work. Also
