when was the steam engine invented<
In 1698, English engineer, Thomas Savery patented the first crude steam engine. Savery used his invention to pump water out of a coal mine. In 1712, English engineer and blacksmith, Thomas Newcomen invented the atmospheric steam engine. The purpose of Newcomen's steam engine was also to remove water from mines. In 1765, Scottish engineer, James Watt began studying Thomas Newcomen's steam engine and invented an improved version. It was Watt's engine that was the first to have a rotary motion. James Watt's design was the one that succeeded and the use of steam engines became widespread.
Making the world better, one answer at a time. Steam engines were the first engine type to see widespread use. They were first invented by Thomas Newcomen in 1705, and James Watt (who we remember each time we talk about 60-watt light bulbs and the such) made big improvements to steam engines in 1769. When the valve opens the cylinder to release its steam exhaust, the steam escapes under a great deal of pressure and makes a choo! sound as it exits. 2  When the train is first starting, the piston is moving very slowly, but then as the train starts rolling the piston gains speed. 3  The effect of this is the Choo.....
