Answer:
An aeolipile, 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. Torque is produced by steam jets exiting the turbine. The Greco-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 architecura.[3]
