Thanks for your answers.
So it is possible to barely lift the propulsion system itself, but not any significant payload. Unless there were "unlimited" amounts of energy available and more efficient ways to create strong magnetic fields with lighter materials.
It could work sometime in the future?
Question from a complete layman:
Would it be possible to build a propulsion system that continually ionizes air with a laser or high voltage und uses a strong magnetc field to push itself away from the ionized air?
If the ionization rate of "new" air is high and quick enough, this should work...
