- Invention of AEOLIPILE (a stream powered device)
Hero(or Heron of Alexandria was an ancient Greek mathematician and engineer worked with air pressure and steam to create source of power.
One experiment that he was developed was the aeolipile which used jets of stream to create rotary motion.The aeolipile consist of a vessel, usually such as a sphere or a cylinder, arranged to rotate on its axis, having opposite bent or curved (L-shaped) nozzles projecting from it. When the vessel is pressurized with steam , steam escaped through the nozzles which gave thrust sphere that caused it to rotate.
The importance of the aeolipie is that it makes the start of engine invention.
