"Liquid Fuel" =/= "Fossil Fuel"
If ICEs are developed for aviation, they a) Don't need to be reciprocating engines, and b) can be turbo-prop gas turbine engines that will run on any flammable liquid.
Still, we've argued ICEs to death, without addressing where aircraft are going to land and takeoff. Are land-based airplanes going to dominate; are they going to need square miles of flat, open space for runways?
Or is Safehold aviation going to be water-based with designs like the China Clipper, Martin Mars, or H4 "Hercules" going to dominate aviation?
