The Wind-Sphere Ship

Heron of Alexandria, in the 1st Century A.D., invented a primitive steam engine he called an aeolipile, or “wind-sphere.” Persuaded by his friend Praxiteles, he used this engine to propel a ship. If his steam-ship could beat a man-rowed galley in a race, could Heron bring about the Industrial Revolution 1700 years early? The action never ebbs in this tale of friendship, technological vision, and one of history’s missed opportunities. Let the race begin!
