Why not just make oil out of waste using fusion power to provide heat and hydrogen and run conventional aircraft off of it with no infrastructure change?
Emissions is my worry.
Well there will be no net CO2 emissions, NOx will still be a problem but as others have mentioned: we replace building heaters/boilers with electic heaters (running on fusion power), replace all fossil fuel powerplants with fusion, replace large ships and train powerplants with fusion, replace small cars and buses with hydrogen/battieres or some other electrochemical storage fuel, that means that we cut 100% of all coal burning, almost all natural gases uses (aside for sporting goods uses) and 40-45% of oil uses (making gasoline), all you need “Fusion oils” for is heavy machinery, sports craft and goods, aircraft, asphalt, plastics and other commercial material. All this at the sacrifice of having to retain a small percentage of our present day NOx pollution, oh and at the sacrifice of all our garbage and waste… and sacrifice in CO2 as it is sequestered from plants into making food and waste, which is transformed into oil and then into plastics and asphalt, ripped from the carbon cycle. So we could even reduce and stop global warming and make commercial products at the same time, what a horrorable idea!
as for all your other questions, they should be answered at
