Aeolipile Supplying Copper-Smelting Fire
Bildnummer 12631241
| An aeolipile supplying a blast to a copper-smelting fire. A hollow bronze ball with a small opening through which water is poured. When the water boils a strong blast issues from the ball. In the first century AD a Greek inventor known as Hero of Alexandria came up with a new invention that depended more on the mechanical interaction of heat and water. He invented a rocket-like device called an aeolipile, also known as Hero's engine. It used steam for propulsion. Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas travelled through the pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, and in doing so gave a thrust to the sphere that caused it to rotate. | |
