A modern replica of Hero's aeolipile. It is not known whether the aeolipile was put to any practical use in ancient times, and if it was seen as a pragmatic device, a whimsical novelty, an object of reverence, or some other thing. A source described it as a mere curiosity for the ancient Greeks, or a "party trick". [7]
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). [13]
1st century AD – Hero of Alexandria describes the Aeolipile, as an example of the power of heated air or water.The device consists of a rotating ball spun by steam jets; it produced little power and had no practical application, but is nevertheless the first known device moved by steam pressure.
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]
The timeline of historic inventions is a chronological list of particularly significant technological inventions and their inventors, where known. [ a ] The dates in this article make frequent use of the units mya and kya , which refer to millions and thousands of years ago, respectively.
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.
Ancient literature comprises religious and scientific documents, tales, poetry and plays, royal edicts and declarations, and other forms of writing that were recorded on a variety of media, including stone, clay tablets, papyri, palm leaves, and metal.
The citation is on the Aeolipile page, Ten Books on Architecture, Book I Chapter 6.2 (Morris Hicky Morgan translation with illustrations). I was working on a paper and wanted to reference the first use of a steam engine (it sounds to be essentially as a toy or science experiment).
