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 ...
Torque is produced by steam jets exiting the turbine. The Greek-Egyptian mathematician and engineer Hero of Alexandria described the device in the 1st century AD, and many sources give him the credit for its invention. [1] [2] However, Vitruvius was the first to describe this appliance in his De architectura (c. 30-20 BC). [3]
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.
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]
Timeline of motor and engine technology (c. 30–70 AD) – Hero of Alexandria describes the first documented steam-powered device, the aeolipile. [1] 13th century – Chinese chronicles wrote about a solid-rocket motor used in warfare. 1698 – Thomas Savery builds a steam-powered water pump for pumping water out of mines. [2]
Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [ 1 ] Heron studied the pressure of air and steam, described the first steam engine , and built toys that would spurt water, one of them known as Heron's fountain.
Steam engine: Archimedes invented the first steam-powered device however, Hero of Alexandria designed the Aeolipile. The aeolipile is a simple bladeless radial steam turbine which spins when the central water container is heated. Torque is produced by steam jets exiting the turbine, much like a tip jet.
The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The library was part of a larger research institution called the Mouseion , which was dedicated to the Muses , the nine goddesses of the arts. [ 10 ]
