I suggest that you fact this. The 787 is a bleedless design in order to improve thrust efficiency and cabin air quality. It's one of the biggest selling points of the plane. Increases engine efficiency by about 30%, or so Boeing claim. I even posted a photo of the cabin air intake, tellingly about 20 feet away from the nacelle.
Anyway, to reiterate my point from earlier, cabin air quality sucks on all planes but sucks less on a 787.
Edit: the 30% figure is nonsense as I described it. It reduces power taken from the engine by 30%, it doesn't improve efficiency by that much overall.
