I'm not sure the op's question was answered, but there's a hypothesis based on a paper published by European researchers last year that it's the quantum vacuum that determines the speed of light. Basically as photons travel from point A to point B they have to interact with the virtual...

Yes an ion drive has a lower density thrust since the propulsive mass is ions, that's why its use is limited to space propulsion applications that don't require high velocities. Anyway MIT did a study last year on ionocraft and found that they're a method of propulsion that's 50 times more...

It's a valid idea actually. If one used ionocraft technology properly scaled up and integrated it into aircraft it could work as an air taxi service. Sort of like a flying car. And GPS could be used for navigational support.
