History of Steam Engines
In 1698, Thomas Savery invented the steam engine. It produced an up-and-down movement and was used for pumping water out of mines, but it had problems with boiler explosions. By 1783, James Watt had built a much safer steam engine which could produce rotary motions. In time, these engines became very powerful and were used to drive all kinds of machines during the industrial revolution.
