The first steam engine：
In 1712, the Englishman Thomas Newcomen invented a steam engine that does not rely on humans and animals to do work but relies on machinery to do work. It is called the Newcomen steam engine.
In 1757, James Watt, a mechanic who was a carpenter, was hired as a laboratory technician by the University of Glasgow in the UK. He had the opportunity to get in touch with the Newcomen steam engine and became interested in the Newcomen steam engine. In 1769, Watt cooperated with Bolton to invent a steam engine equipped with a condenser. In November 1774, they collaborated to build a real steam engine. The steam engine promoted the development of the machinery industry and even the society, and laid the foundation for the development of steam turbines and internal combustion engines.
The birth of the steam car：
In 1769, Frenchman N.J. Gunew made the world's first steam-driven three-wheeled car. This car is named "Caboole". It is 7.32m long and 2.2m high. A large boiler like a pear is placed on the frame. The front wheel diameter is 1.28 meters and the rear wheel diameter is 1.50 meters. Rely on the front wheel to control the direction. It needs to stop and heat for 15 minutes for every 12~15min forward, and the running speed is 3.5~3.9km/h. The second car was built in 1771, and it hasn't really been run. It is now on display at the National Art Museum in Paris, France. Although this invention of Gunew failed, it was a watershed between ancient transportation (powered by people, animals or sails) and modern transportation (powered by machinery), and it was of epoch-making significance.
By 1804, Tweedik had designed and manufactured another steam car, which also carried a 10T cargo on the railway for 15.7km.
In 1825, the British Swady Gane built a steam bus with 18 seats and a speed of 19km/h, which was the first bus operation in the world.
In 1831, Swatch Güller of the United States put a steam car into transportation, and regular transportation services appeared between Gerst and Cherotenham 15km apart.
Later, steam engines developed into external combustion power sources for railway vehicles and ships. People were looking for portable power devices with high power-to-volume ratio and power-to-weight ratio for automobiles.
