A '''steam engine''' is a machine that turns the energy released by burning fuel into motion. [[Thomas Newcomen]] built the first crude, but workable, steam engine in 1712. [[James Watt]] vastly improved the device in the 1760's and 1770's. Steam power was later applied to moving machinery in factories and to powering ships and [[locomotives]].
