Why would we be worse off? We’d save carbon and give consumers a comfortable way to travel.Yes, obviously we can.
But we will be worse off for throwing vast resources at trying to bring back the halcyon era of sleeper trains.
Are clean aircraft available today, tomorrow or within the next 10 years? It does not seem so. Now you may have the magic formula up your sleeve and haven’t told anyone, but it seems unlikely!The jet era is here, there is no going back.
High speed rail might be able to beat the jets for Europe, but overnight sleeper trains have no chance - they just can't move enough people to be economic, and in any case can't really use high speed lines in Europe.
Fischer Tropsch fuel synthesis has been in industrial-scale operation since about 1940. As I said before, it predates the arrival of practical jet aircraft.
Leaving aside that wind and solar panels do not self-multiply and have to be built, if we have near unlimited energy then we can just eat the inefficiencies of going electricity-hydrogen-fischer tropsch kerosene-aircraft.
True. But you’re still pumping out gasses directly into the atmosphere. You’ve got a couple more people on the flight, whoopie.Even with today's electricity it is about an 80% saving and this will increase further with time.
The calculations from my PhD put the electricity gCO2/kWh for zero saving at over 700g/kWh.
UK electricity is now about 160g/kWh and falling rapidly.
Well.... business people would just travel in the normal seats with everyone else?
Hopefully you’d leave the one at the front in placeThe average age of airliners is pretty young compared to trains (~11.6 years globally), so you wouldn't have to retrofit airliners to remove the windows.
It's hard to get good figures but most outline studies suggest fuel savings of ~30% or so from eliminating the windows.
Why? There is less resistance to propulsion?They are very heavy.
Trains by contrast don't care so much about the weight of the train.

Taxation of aviation fuel is prohibited under article 24 of the Chicago Convention of 1944, which governs international civil aviation.
Oh well that’s that then. We must not ever change this law.
