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 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 ...
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.
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 ...
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]
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 ...
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.
