Invented. 1884 (140 years ago) (1884) A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. [1][2] Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel ...
Steam was a familiar technology, adapted well to local facilities, and also consumed a wide variety of fuels; this led to its continued use in many countries until the end of the 20th century. Steam engines have considerably less thermal efficiency than modern diesels, requiring constant maintenance and labour to keep them operational. [96]
History of the steam engine. The 1698 Savery Steam Pump - the first commercially successful steam powered device, built by Thomas Savery. [1] The first recorded rudimentary steam engine was the aeolipile mentioned by Vitruvius between 30 and 15 BC and, described by Heron of Alexandria in 1st-century Roman Egypt. [2]
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

A steam locomotive from East Germany. This class of engine was built in 1942–1950 and operated until 1988. A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder.
Western Maryland Scenic Railroad 1309 is a compound articulated class "H-6" "Mallet" type steam locomotive with a 2-6-6-2 (Whyte notation) wheel arrangement. It was the very last steam locomotive built by the Baldwin Locomotive Works in November 1949 and originally operated by the Chesapeake and Ohio Railway (C&O) where it pulled coal trains until its retirement in 1956.
Advanced steam technology (sometimes known as modern steam) reflects an approach to the technical development of the steam engine intended for a wider variety of applications than has recently been the case. Particular attention has been given to endemic problems that led to the demise of steam power in small- to medium-scale commercial ...
A steam motor is a form of steam engine used for light locomotives and light self-propelled motor cars used on railways. [1] The origins of steam motor cars for railways go back to at least the 1850s, if not earlier, as experimental economizations for railways or railroads with marginal budgets. These first examples, at least in North America ...
