Being a bit of a technology history buff, that's not what actually happened.
It might have application to AI discussion as an example like the scanning 
probe microscopes--which could have been done with technology from the 
1930s.  (I.e., the idea that an AI could exist in a 386 computer if we just 
knew how.)
Commercial steam power (for pumping out mines) originated in the Newcomen 
engine.  There is a good drawing of it here:

These engines were called "atmospherics" because they used steam at 
insignificant pressure over that of the atmosphere.  The cylinder was 
filled steam, the steam condensed with a spray of water into the cylinder, 
generating a partial vacuum atmospheric pressure pushed the piston into the 
cylinder.  They were horribly inefficient, partly because heating and 
cooling the cylinder.  Watt's invention can be summed up in two words 
"separate condenser."  He obtained a patent and for the time became rather 
well off.
Having 6 patents myself, I can make further comments about their value and 
problems if there is interest.
