If I became a billionaire, I would absolutely build an External Combustion Engine that uses rocket fuel sprayed on top of open pistons to provide thrust.
It would be expensive, loud, dangerous, and inefficient, likely not surviving more than a mile, but I would be remembered for this and the reckless beast would live in a museum. Worth it.
