@GK, thanks for that NMR video, great stuff!
@all,
I have some comments about the the compass spinning video. I remember that in my Physics class I took many years ago, we had a lab assignment to map the magnetic field around a bar magnet. The bar magnet was laid on the table and we placed small compasses around it and market the direction that it pointed and made a drawing of it. As you can imagine, the earth magnetic field plays a role and skews the magnetic field of the magnet, or vice versa, so that we don't get a symmetric pattern. However, the amazing thing that we all found out, and the teacher pointed it out, was the precise location where the two magnetic fields cancel, and at that location a compass would spin! I can see it now, just sat there spinning like crazy! You had to have it just right.
Now, I don't know if that represents free energy, because the compass had some energy as it was moved to that location, but if we could stop it from spinning while placed at that location, would it start spinning again by itself?
The reason the compass doesn't spin in a stronger field, even though it is jerked into the field, is because there are losses, and they depleate the kinetic energy it has, but at the null location, those losses are minimum, (the compass is not pulled heavily one way or another so the frictional losses in its bearings are minimal)
So to experiment along these lines, do the following:1) get a bar magnet and place it on a large sheet of paper
2) take a small compass and move it around it and record the orientation
3) soon enough you will get a picture of where fields (earth and magnet) begin to be equal and perfectly cancel, so place the compass at this location
4) stop the compass somehow, and see if it picks up its spinning all by itself. If it does, then we have something worth pursuing.

PS, see this link:
