Steam engine

• The world’s first steam engine was called the ‘Aeolipile’ and was invented by the Greek mathematician and engineer, Hero of Alexandria (c. 152-82 BCE or 10-70 CE).

Description

• Hero developed a sealed boiling cauldron with two pipes rising up into a suspended metal sphere.
• The sphere had twin jets and as the steam exited the jets, the sphere spun on its axis.
