Steam power developed slowly over a period of several hundred years, progressing through expensive and fairly limited devices in the early 17th century, to useful pumps for mining in 1700, and then to Watt's improved steam engine designs in the late 18th century.
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.

Even so, around the year 1800, "high pressure" amounted to what today would be considered very low pressure, i.e. 40-50 psi (276-345 kPa), the point being that the high-pressure engine in question was non-condensing, driven solely by the expansive power of the steam, and once that steam had performed work it was usually exhausted at higher-than ...
Steam-powered showman's engine from England. The history of steam road vehicles comprises the development of vehicles powered by a steam engine for use on land and independent of rails, whether for conventional road use, such as the steam car and steam waggon, or for agricultural or heavy haulage work, such as the traction engine.
Timeline of motor and engine technology (c. 30–70 AD) – Hero of Alexandria describes the first documented steam-powered device, the aeolipile. [1] 13th century – Chinese chronicles wrote about a solid-rocket motor used in warfare. 1698 – Thomas Savery builds a steam-powered water pump for pumping water out of mines. [2]
The condensing cylinder was water cooled to keep the steam condensing. At the end of the power stroke, the valve was closed so the power cylinder could be filled with steam as the piston moved to the top. The result was the same cycle as Newcomen's design, but without any cooling of the power cylinder which was immediately ready for another stroke.
Steam engines remained the dominant source of power until the early 20th century, when advances in the design of the steam turbine, electric motors, and internal combustion engines gradually resulted in the replacement of reciprocating (piston) steam engines, with merchant shipping relying increasingly upon diesel engines, and warships on the ...
Age of Steam or Steam Age may refer to: A period of industrialization in parts of Europe between roughly 1770 and 1914; Steam power during the Industrial Revolution; Steam-powered vessels; History of the steam engine
