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.
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.
Hero published a well-recognized description of a steam-powered device called an aeolipile, also known as "Hero's engine". Among his most famous inventions was a windwheel, constituting the earliest instance of wind harnessing on land. [3] [4] In his work Mechanics, he described pantographs. [5] Some of his ideas were derived from the works of ...
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]
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.
Roulette was developed in 18th century France [9] from a primitive form created by Blaise Pascal (17th century). [10] In 1843, Louis and François Blanc introduced the single 0 style roulette wheel. Many other gambling games and card games (including the French suits around 1480) [11] were invented in France, some from earlier games :
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 ]
In Roman Egypt, Heron of Alexandria invented the aeolipile, a basic steam-powered device, and demonstrated knowledge of mechanic and pneumatic systems. He was also the first to experiment with a wind-powered mechanical device, a windwheel. He also described a vending machine. However, his inventions were primarily toys, rather than practical ...
