I saw a video by Michio Kaku, showcasing levitation of a small object with a superconductor cooled by liquid nitrogen. It's the same technology used by some trains.
Hypothetically, how possible is it to achieve free human flight by some way of:
- Putting a thin, light (say 5kg) bed, under a human in a fly suit. The bed is coated with the magnetic material of one polarity.
- This bed has some sort of continuous thrust mechanism, with the required thrust to keep only it afloat & to fly it around. (It's very light due to carbon nano tubes, high technlology etc.)
- On top of this bed is a freely floating human in a suit made of the opposing superconductor (or however this works)
So essentially the bed is what's really flying around and has tiny thrust requirements because of it's weight and the human is levitated at essentially minimal cost (due to the superconductor)
