In theory, would it be possible to use this with the earth's gravity? or would it's own weight bring it down? also how much of it would be needed to lift, say, 2 people with average weight.

It doesn't ADD any energy to the equation; and even the slightest losses will accumulate over time and allow it to settle. However, it IS a superconductor, so these losses are minuscule on a short timescale.

What exactly do you mean by that?

Whoever put that name up, I hate them SO much.

It's simple maglev with supercontuctors. It's not new.

It could definitely be used, but the expense of cryogenic systems make it prohibitively expensive.

use the earth's magnetic field in place of the magnets in the demonstration. would that be possible?
