A Greek inventor by the name of Hero of Alexandria, described the toy Aeolipile that he build circa 75 CE. The Aeolipile is a primitive and workable reaction Turbine.
Basically a hollow ball with nozzles on opposite sides and pointing in opposite directions. Mounted on it’s pivot on two tubes that extend from the steam cauldron. when the steam cauldron is heated, the liquid inside converts to steam, which flows through the tubes, entering the ball, as preasure increased the steam is released via the nozzles, the more steam the faster it spins.

Actually a steam reaction turbine, the Aeolipile was invented by Heron of Alexandria in the first century A.D. In modern times it is often referred to simply as “Hero’s Ball”. This ingenious device was described in detail in Heron’s book Pneumatica. A fire beneath the cauldron boils water, producing steam which is conducted through one of the copper supports to the pivoted brass sphere.
