well this is relatively close(but not the save)
https://en.wikipedia.org/wiki/Ion_thruster
perhaps such a device would create a vacuum around it in a similar way a tornado spins in-place? and then it propells itself upwards into space using the vacuum followed by a variant of an ion thruster?
@lucifargundam Ion thrusters would be useless in this situation. Ion thrusters are useful once your in space, they are useless when it comes to getting off the planet.
@freemo my apologies, thats what I meant by "followed by"... as in after getting out of orbit.
@lucifargundam ahh yes, but since we are talking about a space hotel orbiting earth that is a moot point. Once your in orbit thats the easy part if your not in a rush :)

The truly most efficient form of space travel would be via
coming to a theater near you.
@lucifargundam The day someone creates an efficient high-thrust electric rocket that can operate in a vacuum is a day physics is going to change on a very fundamental level.
