It could help produce a transport system that works without fuel

What about this statement. Wouldn't the superconductor need some form of fuel?

[philosofy123]

Typically, you use a very cold substance to achieve superconductivity. To get to that cold state, you must have fuel? Currently, it takes too much energy to get to the superconductivity; perhaps in the future we may get more efficient in achieving that state?
