An interesting story, but I wonder about it. Namely, what sort of steam
power might it have used?
James Watt did his revolutionary work from approximately 1765-1775 (using
Wikipedia here, which is unscholarly practice, but these numbers are
likely to be good enough); and the result was a line of huge stationary
engines, which you can go and admire on the ground floor of the science
museum in South Kensingon, London. (Including an instance of the first
device ever put into production with a feedback mechanism.) Shrinking that
enough to try to make a railroad engine was a project that people started
pretty soon, but not something that would have had even a qualified
success before 1776.
And we can definitely forget a Newcomen engine. Does anyone know what the
Frenchman tried?
