I think reading history inspires me to ask if some innovationseems possible and to move into development. Rudolph knew that compression produces heat, and if stoichiometric fuel ratio, ignition, and pressure impulse timing were separated, there would be efficiency gains, but how to do it? The development nearly killed him directly and ultimately got him thrown off of a ship by fearful oil czars, but what an amazing journey. Without inspiration from the pioneers before us would we dare to try anything risky?
