Why can't we use superconductor as a shield?

Hi everyone.I have been focusing on superconductor shielding.Searched a lot and for me it is nonsense to use SC in a magnet motor design.Let's assume that we have superconductor in room temperature.It will act like this one.( http://www.youtube.com/watch?v=c3asSdngzLs ) Ok SC repels all the magnetic fluxes from the magnet but fluxes surround it.So when you try to lift the magnet,SC comes with it."When you lift the magnet up, the force of gravity acting on the pellet (F=ma first semester physics stuff), is not great enough to force the trapped magnetic field to pass though the superconducting material, hence, like a weight on a string, you can lift the pellet. The string in this case is the magnetic field, and the weight is the superconductor."(http://www.imagesco.com/articles/superconductors/superconductor-meissner-effect.html).It needs energy to seperate them.

What do you think?

Where are comments?Don't you find it interesting? ???

hey radmag,
                  you say that you have done a lot of research on superconductors, but if you had you would know that as of yet we can not have a superconductor in room temp. so far we can only make a sc by cooling it close to absolute zero. and that would consume more energy that you would make.That is why as of yet we can not use a superconductor as a shield.
I'll see your theory, and raise you mine!!!

First of all thanks so much for your entry tournamentdan(what a long name:))If you had read carefully you would notice "let's assume".I know there is no sc in room temp.But I think energy problem is not about cooling it.Assume that there is sc in room temp.Can we use it as a shield in a magnet motor design?

What makes you think a magnet motor would run just because there is a shield.
If you design it in repel mode the magnets will wear out quickly or simply stop in equilibrium where the forces are the weakest.
In attraction mode it will stop in right away in equilibrium where the forces are the strongest, regardless of any shield.
