Technically, it needs insulation and a way to radiate heat. I read a while back that the superconductors used in space are often wrapped in several concentric shells to avoid being exposed directly to the sun and other onboard heat sources.

Is there a limit to the amount of thrust that these superconducting magnets could generate in Earth’s magnetic field? I read a hypothesis that the UAPs that have been observed to accelerate without any propellent are using superconductors in this way.

Sounds expensive. Most nans weight a lot of pounds.
