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]
Some historians have conflated the two inventions to assert that the aeolipile was capable of useful work. [15] A vending machine that dispensed a set amount of water for ablutions when a coin was introduced via a slot on the top of the machine. This was included in his list of inventions in his book Mechanics. When the coin was deposited, it ...
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 ...
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.
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.
Greek inventions and discoveries are objects, processes or techniques invented, innovated or discovered, partially or entirely, by Greeks. Greek people have made major innovations to mathematics , astronomy , chemistry , engineering , architecture , and medicine .
