- FlyMoreRockets 8y agoMaybe. At high altitudes, the ions can be accelerated to much higher velocities before losing energy due to molecular collisions. Higher acceleration of the working fluid, more thrust and higher efficiencies. Much like a rocket. There is also a lot less drag on the rest of the vehicle.
