There was this guy in the 1st century A.D., named Hero of Alexandria. He is famous for inventy many things, but is most famouse for inventing the aeolipile, a steam engine, used as a toy. What if he went a step furthur, far enough for an industrial revolution in Acncient Rome? The Romans could biuld trains and steam ships, all faster then previous ways to travel! The Revoulution changed the world in the 1800's, something new invented every month. Assumming the Romans would biuld trains, legions could be transported faster, it took 54 days to march from Rome to the English channel according to The Oxford Latin Course Part III second ed. I predict that The Barbarians would've been defeated, purhaps even the Parthian Empire would be conquered, and, the Roman economy being based on conquests, march through India before 500 years of the intro. of the steam engine. the Romans could respond to threats quicker then ever!
Anyway, a few points. First of all, the aeoliopile was likely a demonstration device, not a toy. Heron, in addition to playing with steam, pneumatics, gears, automata, etc. also went on for quite a bit about experimental results, such as using an experiment to disprove the contemporary theory behind why a syphon works. He came much closer to a scientific method than an industrial revolution.
Second of all, the aeolipile was useless. Terrible torque, terrible seals, expelled water constantly, etc. Spun really fast though, and looked really cool. Plus, how would you do anything with it?
Third, the Industrial Revolution was more a function of population and economy than technology, both of which were far more advanced in Britain of the 19th century than in Rome of the 1st.
Fourth, the metallurgy of the Romans wasn't advanced enough to make steam power practical. And locomotives? Ugh. Steamships would work far better.
However, on the bright side. The Romans have relatively effecient pumps. Heron's own wind powered organ showed that he had the idea of transforming rotary motion into reciprocal motion. The other way around is more useful, though, when you want to use steam power for transportation.
So, an industrial revolution is a no go for the forseeable future. However, steamships were remotely possible (the romans did have a concept of paddlewheel ships).
