Well, it seems to me that if they merely thought of what steam power
could do for ****ps, that the thought alone would have created its own
demand. But, for one, I know if something performs poorly when first
demonstrated, that provides negative feedback, which may lead to it
being dropped. Like the French military officer who invented a steam-
powered automobile shortly before the American Revolution (1769,
maybe?). It moved very slowly and crashed into a house, and his
superiors told him to drop this research.
People would have to think beyond early stage failures. All the early
stage failures in the U.S. rocket program did not deter us, in part, I
assume, because we knew the objective was obtainable: the Russians had
already launched rockets into space!
