Eddie: So let me explain what we've got here.
Eddie: The ship runs on three type R fusion based boosters. Our primary reactant is Hydrogen, with some helium, in it's plasma state.
Kid: You didn't mention anything during the tour about fuel storage, and the ship's pretty small. Where do you keep it?
Eddie: We don't. We gather it actively as we fly with three Bussard collectors on the front of each engine.
Pause
Kid: Aren't Bussards things you wear to make your hips really fat?
Eddie: I think that's where the name comes from, historically.
