Who invented the world's earliest steam engine in Britain?

The first steam engine in the world was invented by Greek mathematician Herod of Alexandria in the 1 th century, which was the embryonic form of the steam engine.

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. At about the same time, Samuel Moran also proposed the steam engine.

Thomas Seville in 1698, Thomas Newcomen in 17 12 and james watt in 1769 made early industrial steam engines, all of which made their own contributions to the development of steam engines. 1807, robert fulton was the first to successfully use a steam engine to drive a ship. Using scientific theory, Watt gradually discovered the faults of this steam engine. From 1765 to 1790, he made a series of inventions, such as separate condenser, cylinder external insulation layer, piston lubricated with oil, planetary gear, parallel linkage mechanism, centrifugal governor, throttle valve, pressure gauge and so on. , make the efficiency of the steam engine to more than three times that of the original newcomen machine, and finally invented the modern steam engine.
