I don't understand--- If you try to "block" it you'll force it into itself and risk demagnetization

A PM's magnetic field is a closed loop always going back into itself , if you shield it you are just redirecting the field back into itself, instead of a ferromagnetic material, so effectively the magnet thinks it is nowhere near this ferromagnetic material- the shield is not repelling the field it is magnetically neutral or zero force, the original PM field just cannot penetrate it- Big difference.

what if it were to be used in this fashion? http://www.overunity.com/index.php/topic,1073.0.html were the arms of the wheels flaps close "blocking" the magnetic field. with the help of gravity.

A material that "repels" the field is not suitable.  Put the "keeper" on a horseshoe magnet - notice that it will no longer attract anything.  Put a piece of steel over the face of a magnet and that face will no longer repel another magnet.  Try it.  Two magnets and a piece of steel - use the top of a can or a steel rule - don't even bother cutting it to size, just slap in over the face of the magnet.  You should notice that the face of the other magnet that once was repelled is not atracted.  Nature is pretty slick...

Useing a keeper to short circuit PM flux is common knowledge, the problem is you can never come out ahead because the force to remove the keeper is equal to the force that put it there. I am not talking about a repulsion field in the shield, Im refering to shield that has a balanced field. Here's a good experiment-
Take two magnets in repulsion about 1" apart then insert a thin metal piece of flat iron exactly inbetween both magnets. You will notice than the magnets no longer repel each other, and if the space between the magnets and flat iron is correct they do not attract to the metal of the flat iron either because the attraction to the metal is balanced with the repulsion between the magnets, so the system is balanced.
So what if you made a shield that was balanced internally due to the materials used, it would not be attracted or repelled from magnetic fields,but would block them by redirecting the field back into itself. By redirecting a field back into itself I mean the north pole field would rather return to the south pole because the route around the shield is longer and magnetic fields take the shortest route in a closed system. to understand this google magnetic levitation they use balanced fields, it's interesting that most physicists said magnetic levitation was impossible, which is now common place-once again the scientists put there foot in there mouth.

This is not true.  You can move the shield with less energy than the field imparts to the rotor.  Allow the shield to almost touch the magnet - put a thin piece of slick palstic tape over it.  It can actually touch the magnet, but friction may be too high.  You can have a fixed magnet a foot long and it will not take much more force to slide the shield, but the field will be very strong.

The shield does not have to slide all of the way off the face fo the magnet - just enough to expose the field - 3/4's exposure is good.  You can slide it back and forth by hand and get the rotor to spin slowly.

Free Energy...Thank you for your reply...your "flapper" is truly unique!  I think there are some possibilities there.  One thing I am wondering about is that when the flap is open, it offsets the balance of the rotor.  Even though the weight would be the same, the distance from the axle would be greater, putting more leverage on on side.  Even though it would be a little more difficult to build, perhaps a "slider" may be incoporated to keep the axis a closer to "balanced."
