I can already hear you groaning. Here we go again, you're probably thinking. Another revisionist theory that Justin likes, big surprise. You may be surprised to learn, then, that this is no theory: sometime between 10 and 70 CE, Hero of Alexandria created what is believed to be the world's first steam engine. No joke, no hair-brained theory, just cold, hard, unforgiving historical facts. Still don't believe me? Just take a look at this illustration from his book:
Not sure what you're looking at? Well, it worked like this: you poured water into that bowl on the bottom, then build a flame underneath it and waited for awhile. Eventually, that water transforms into steam, which shoots up through the two pipes and into the circular object in the center, which was more like a pinwheel than a globe. The steam would travel out of the two spouts out of the pinwheel, causing it to spin. Presto, ancient Mediterranean steam engine!
In addition to this, Hero is also credited with the invention of the force pump, the syringe, a wind-powered organ, and the vending machine. So, the next time you buy yourself a soda or sodium-coated snack, think of Hero and wonder to yourself what else he may have jotted down on some note paper which was lost along with most of his work when the Serapeum was destroyed in 391 CE by a Christian mob.
