I didn't say present jet engines could be used . I am only going by what i have read here. I was certainly amazed when I read it. I would like to hear from anyone working in the jet engine (not gas engine) area what they think. Even if as you say, the overall efficiency will be less, on a medium to long haul flight the speed will be much higher and thus the flight time much less, a rather more important commercial consideration.
