Could Robert Fulton build a militarily useful steam fleet for Revolutionary France with a blank check?
Short answerPotentially, given enough time and support, but unreliable early engines would fail in significant numbers.
NotesRobert Fulton could potentially produce a meaningful French steam fleet with enough time, money, and institutional support. Funding alone would not make early steam technology mature. The quality of contemporary construction would leave many engines vulnerable to serious failure or explosion. The counterfactual turns on industrial reliability as much as invention or political patronage.
