OOC. NK. Take
this. Assume its potential was realized, given that society was different. Add a few hundred years. Extrapolate.
That is
stupid. Jal, I am well educated on ancient technology, but that was one of the
least promising. Hero's steam engine was utterly useless and inefficient: you would need the thousands of years of advances that came after it to make it of any use: there is a REASON that steam was not utilized until the 1800s; people do not leave a technology
lying around if it is useful.
And if you don't want to take my word for it, here, I'll give the facts and figures.
This device had an efficiency of about 1%, most likely, due to the inherent problems in its design.
So if you were to make a large scale model, and get from it only .1 horsepower, the work that a single man can do, it's fuel consumption would have to be
25,000 BTU per HOUR. Charcoal, the best fuel there was in the ancient world, would be 12,000 BTU per pound. This would have taken far too much work to even get the levels necessary to fuel the monster... For the work of one man.
Now, if you took a piston steam engine, yes, you could get something crudely approximating the idea of a modern steam engine, but to do this, you need several technological geniuses in a
row, multiple Heros of Alexandria, plus no accidents, no discouragement, and a tremendous amount of good luck.
The machining and other problems with this means it is absurd to suppose that the technology could even be developed, let alone mass produced. Even more so, the idea that you've been able to keep it a secret when you have Citadelers wandering all around the world is just plain
stupid.
Furthermore, steam engines in and of themselves are not even that important: only for sea transport and pumping did they really make a dent initially, even when all the elements needed for their design actually WERE around. Far more important were waterwheels and other forms of power, and if you think you have a monopoly on that, then you are delusional.
You might have gunpowder weaponry, but the idea that you've managed to keep THAT a secret is also absurd, and furthermore completely farcical, because we haven't even seen a single story about Citadelers wandering around in the pursuit of alchemy.
Chemistry, machining, power systems, and thought take millennia to advance for a reason; they DO NOT come overnight. Yes, the advances seem obvious to you, because you
live in the bloody modern world.
I made the mistake once of letting a Rome develop gunpowder... But even I, in my newbieness of the time, even I, impressionable, young, and idealistic as I was, didn't let them keep that secret.
