An aeolipile (or aeolipyle, or eolipile), also known as a Hero's engine, is a simple bladeless radial steam turbine which spins when the central water container is heated. In the 1st century AD, Hero of Alexandria described the device in Roman Egypt, and many sources give him the credit for its invention.
