Question 2: Who invented the steam engine? James? Watt Scottish inventor James? Watt is often called the inventor of the steam engine and a key figure in the industrial revolution. Actually, Watt was not the first person to invent the steam engine. In the first century, Alexander? Hiro once designed a similar machine. 1698, Thomas? Saville obtained a patent for pumping water with a steam engine. Thomas, an Englishman in 1712? Niu Kao-men obtained a patent for a slightly improved steam engine. Niukaomen steam engine is very inefficient and can only be used for coal mine drainage. In 1764, when Watt was repairing a Niukaomen steam engine, he became interested in this kind of machine. Although Watt received only one year's mechanical manufacturing training, he has an extraordinary genius for invention. The improvement he made to Cowgate Machine was so important that people thought that he invented the first practical steam engine. Watt's first major innovation was to add an independent condensing room, which was patented in 1769. He also insulated the steam cylinder from the outside world and invented the double-acting engine in 1782. Together with some minor innovations, these inventions have improved the efficiency of steam engines by at least four times. In fact, the improvement of efficiency means the difference between a flashy device and a machine with great industrial value. In 1781, Watt also invented a set of gears, which transformed the reciprocating motion of the steam engine into rotary motion. This set of gears has increased the use of steam engines. Watt also invented the centrifugal governor (1788), manometer (179), counter, indicator, throttle valve and many other instruments that can automatically adjust the running speed of the steam engine. Watt himself doesn't have a good business mind. But in 1775, he met with a very capable businessman and engineer, Marlowe? Bourdon formed a Watt-Bourdon company in partnership. The company produced a large number of steam engines, and both shareholders became rich. The importance of the steam engine cannot be overestimated. Of course, many other inventions appeared in the industrial revolution, such as in mining, smelting and many industrial machinery. Several of these inventions, such as the pulley shuttle (John? Kay, 1733) and Leni spinning machine (James? Hargraves method, 1764) all appeared before Watt started. Most of the other inventions only represent minor changes, and none of them can play a decisive role in the industrial revolution alone. However, the steam engine is different. It plays a key role. Without it, the industrial revolution would be beyond recognition. Before it, although windmills and water wheels had certain uses, the main power source has always been the human body, which seriously limited industrial productivity. With the invention of the steam engine, this restriction was eliminated. Now that there is huge energy available for production, production has also increased greatly. The oil embargo in 1973 made us realize how seriously the lack of energy would hinder the development of industry. This experience will make us realize the significance of Watt's invention to the industrial revolution. Besides being the power source of the factory, the steam engine has many other important applications. In 1783, Marcus? Jufelroy? Dabans successfully used a steam engine to drive the ship's voyage. In 184, Richard Trevize made the first steam locomotive. However, these two models are not successful economically. However, within a few decades, ships and railways have revolutionized land and water transportation. Historically, the Industrial Revolution appeared almost at the same time as the American Revolution and the French Revolution. Although people didn't seem to have a clear understanding of the industrial revolution at that time, today we can see that its role in human daily life is obviously much more important than those two great political revolutions. So, James? Watt is one of the most influential figures in history.
question 3: who invented the steam engine? the first steam engine in the world was a rotating ball invented by the ancient Greek mathematician Hero of Alexandria in the 1st century.
in about 1679, the French physicist Dennis? Papen made the working model of the first steam engine after observing the steam escaping from his pressure cooker. About the same time, Samuel? Moran also put forward the idea of a steam engine.
Thomas in 1712? Newcomen and James in 1769? Watt made early industrial steam engines, and they all made their own contributions to the development of steam engines. Robert in 187? Fulton was the first to successfully use a steam engine to drive a ship.
Watt was not the inventor of the steam engine. Before him, a steam engine, the newcomen Steam Engine, appeared long ago, but it consumed a lot of coal and was inefficient. Watt improved the efficiency of the steam engine to more than three times that of the original newcomen machine, and finally invented the modern steam engine, which really popularized the steam engine.

question 7: who invented the steam engine? As early as the 13th century, Rogier, a pioneer of British experimental science? Bacon once predicted with genius: "In the future, horse-drawn carriages will fly at incredible speed." This is a bold and novel idea. However, this prophecy of Bacon and his other thoughts were regarded as "heresy", and Bacon himself was persecuted crazily. In the second half of the 18th century, steam engines were widely used, and social productive forces were greatly developed. However, at that time, land transportation still relied on manpower and animal power, which was far from meeting the needs of socialized mass production. Before there were trains, there were a few "carriage railways", which used horses to pull wagons on the rails, which slightly improved the transportation efficiency. The earliest steam cars (both locomotives and wagons) can carry very little goods, walk slower than horses and wagons, and often derail or damage railways. At the beginning of the 19th century, many people thought of using the steam engine as a traction force to change the backward land transportation. Some creative people began to explore this aspect. After repeated experiments, the Frenchman Cournot made a three-wheeled "steam street car", which can drive on the road. Its structure is extremely simple and its speed is slow. The French War Department is interested in this steam car and wants to use it to equip the troops and improve the marching speed. The war department copied a similar vehicle, which weighed 12 tons, 3.6kw and advanced 7km per hour. Unfortunately, however, this steam car was once overturned while driving on the streets of Paris, and it has been banned from use ever since. In 1784, Watt's assistant, British Murdoch, also made a steam car. One night, he took the steam car model to a flat road 1.6km away from the town for an experiment. He lit the boiler and the locomotive roared forward. Unfortunately, a pastor of the church just walked out of the church. He saw a steam car with a strange cry coming at him, thinking that it was attacked by the devil, and he was scared and shouted for help. This incident caused a storm in the city, and people turned pale when they talked about cars. After knowing this, Murdoch's boss was furious, forbidding Murdoch to try the scary "monster" again and punishing him for doing double work. Murdoch's experiment failed to get people's understanding and support, and even his teacher Watt was worried that he would be immersed in unnecessary research and delay his work, and advised him to stop exploring in this area. Murdoch had to give up the development of steam cars. An Englishman, Trevisick, inherited Murdoch's career, made a steam locomotive in 183 and exhibited it publicly in London, which caused a great sensation for a while. But once, due to careless driving, it crashed into the wall of a building, so the motorcycle show stopped. In 184, Trevize made another steam locomotive. This is the world's first locomotive running on the rails, with a total weight of 5 tons, which can pull more than 1 tons of goods for 8km per hour. Because the locomotive itself is very heavy and must carry a lot of water and coal, it is not as good as the horse-drawn railway vehicle in terms of load capacity and speed. However, it is the embryonic form of the "train" running on the rails in the future. In 188, Trevisi became another steam locomotive. This locomotive was running on a circular track with a diameter of about 3 meters, and thousands of people sat on it with great interest. People felt that the fantasy of "no horse-drawn carriage" was finally realized. But one day, the locomotive suddenly overturned and broke, and the steam locomotive was regarded as a dangerous "monster", and people were afraid of it. Trevisik himself is also disheartened and has no interest in further improvement. In 1812, an Englishman, Moray and others, designed and manufactured a steam locomotive using gears and made it run on a toothed track. However, in the actual use process, the gear is often damaged, so that the locomotive has to stop running frequently. Many people have made all kinds of efforts. Although the real practical steam locomotive has not been made, they have accumulated rich experience.

Question 8: Who invented the steam engine? Hello, classmate. The first steam engine was invented and manufactured by a Scottish blacksmith named Newkman, which was the most advanced steam engine at that time. Before Newkman, many people were interested in steam as power for production. In 1688, the French physicist Deneys? Papan once made the first simple steam engine with a cylinder and a piston. However, Papan's invention was not actually applied to industrial production. Ten years later, the Englishman Toes? Seville invented the steam pump, which is mainly used for pumping water in mines. In 175, after long-term research, Newkman combined the advantages invented by Papan and Seville to create an air steam engine.
