One of those big 'ifs' of the Roman era is how close did they come to having an 'Industrial Revolution' similar to that experienced in the 18th and 19th-centuries? After all, following the same time line that we have - if the atmospheric steam engine had been invented in 12AD, then the Romans may have ended up with nuclear energy in 245AD. Does that sound incredible? It shouldn't. We were no more technically advanced at the beginning of the 18th-century than 1st-century AD Romans, but we still managed to harness (or split) the atom by 1945. Thank goodness they didn't have the stationary steam engine, eh? Can you imagine a world beset with best and worst of nuclear technology for the last 1800-years? Well, trouble is, despite the first successful atmospheric steam engine being credited to Thomas Newcomen in 1712, the first 'usefully employed' steam engine was fired up around 40AD. This was when Hero of Alexander demonstrated the closed-system steam-syphon engine to automatically open and close doors. Perhaps happily (or unhappily) for us, Hero was more interested in theatrics and urban automation rather than finding industrial uses for his steam engines. But the facts are pressurised steam boilers were common place in every Roman bathhouse and Hero proves an understanding for steam cylinders and water pumps...the trouble is, unlike Newcomen - who saw the machine as a solution to pumping water from flooded mines - Hero clearly never visited Spain where he would have seen miners beset with the same troubles as those in 18th-century England. Perhaps if he had, our earliest steam engineer might have seen how an open-system steam engine could replace the dozens of slaves driving the pumps and water-wheels. Makes you think what might have happened if he had.
