In 1698, Thomas Savery invented a pump that worked on steam power. It was used to drain water from mines. It was called Miner’s Friend. It worked very slowly. Moreover when the pressure increased the boiler burst.
In 1712, Thomas Newcomen invented another steam engine. This helped in draining water from the mines in a better way. But the steaming chamber became cold too soon and thus energy was lost and this was a defect of this machine.
In 1769, James Watt developed his steam engine. Until then all the steam machines were used only in the mines. From mere pumps, James Watt changed steam engines to a driving force. His steam engines were suitable for different industries. In 1775, with the help of his friend Mathew Bouton, James Watt established a factory in Birmingham for producing steam engines. This factory-produced steam engines one after the other. By the end 18th century, stream energy of Watt replaced water power.
