An aeolipile, aeolipyle, or eolipile, from the Greek "Αἰόλου πύλη," lit. ' Aeolus gate ' , also known as a Hero's (or Heron's ) engine , is a simple, bladeless radial steam turbine which spins when the central water container is heated.
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]
1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
Heron’s aeolipile is considered an early demonstration of the principles of steam power, although its practical applications were limited in ancient times. Image credits: Isabella Thornton #62 ...
Hero's aeolipile. A number of devices and inventions have been ascribed to Hero, including the following: The aeolipile (a version of which is known as "Hero's engine"), which was a rocket-like reaction engine and the first-recorded steam engine (although Vitruvius mentioned the aeolipile in De Architectura, presumably earlier than Hero).

Jet engines can be dated back to the invention of the aeolipile around 150 BC. This device used steam power directed through two nozzles so as to cause a sphere to spin rapidly on its axis. [ 1 ] So far as is known, it was not used for supplying mechanical power, and the potential practical applications of this invention were not recognized.
Tanks : developed at the same time (1915–1916) in France and in Great Britain. France was the second country to use tanks on the battlefield (after Great Britain). in 1916, the first practical light tank, the Renault FT with the first full 360° rotation turret became, for armour historian Steven Zaloga "the world's first modern tank".

A big size reconstruction of Heron's aeolipile in Kotsanas Museum of Ancient Greek Technology, Athens, Greece. As noted, one recorded rudimentary steam-powered engine was the aeolipile described by Hero of Alexandria , a Hellenistic mathematician and engineer in Roman Egypt during the first century AD. [ 8 ]
