It requires energy to remove the shield from the magnets. There is a connection between the forces and how they are distributed as you change the conditions during the loop. Forces are just "moved around" without actually doing any work.
The shield works well, but unfortunatly the shield is magnetic too and is a part of the system that works against what the piston is suppose to do.

It is true that you have to apply energy to remove sheilds from the magnets.  But this comes into picture only when there is potential difference in the area of movement of shield.  A  shield tries to move from region of lesser flux density to a stronger region.   You can move a shield without spending energy (other than to overcome friction) in a uniform magnetic field which will not have  potential difference.   

In the system what I have drawn a potential differnece will still be created when small magnet(piston) comes closer to the  stationary magnet.  But the force you have to apply on the shield to overcome this P.D.  is less compared to repulsive force which piston experiences from stationary magnet which is product of strength of both poles ( H1*H2 / d square)

I am not quite sure of the above theory but while working with magnets I observed that a shield can be moved freely in a uniform magnetic field espesially using wheels or rollers.  Without rollers the system will not work.

there are ways to shield on one side, and not have a major impact on a magnetic field on the other side.
Such shielding takes place in microwaves and harddrives.

Well, whatever one might do with magnets, they all have a fixed set of magnetic lines (just for imaginary reference). These lines will be the same in number all the time, but over time the numbers are distributed differently at any given conditions of the machine - densed there, and less dense over here. Through a shield, or repelled by another magnet - whatever condition, you've got the same number of magnetic lines. What you gain in one situation will be lost in another, just because the number of magnetic lines did not change over that period of time. You are given a conservative amount of magnetism, that's all you've got, and it's constant in any situation. How can it be possible to maken an all magnet motor that works under these conditions?
