| Mar 20, 2019 at 17:18 | comment | added | AlexP | (1) It was much more like a steam turbine than a jet engine, with ridiculously low efficiency. (2) Crude petroleum is no way shape or form a "high volatility" fuel; it is actually quite hard to ignite. (3) I would not want to be near a pressure vessel made of thin sheets of copper. (4) The Romans had no idea of aerodynamics, and no idea of dynamics in general... | |
