Travis' file section
a couple of notes on your diagrams in the files section
1 - cone device polarity
there must be a ring of magnets on the inside of the barrel
to support each of the cones. the magnets will determine the
size of the gap between the cone and the barrel. usually for
ceramic 5 magnets, they should be about 1/8 to 1/16 inch apart.
2 - isotope video. keep in mind when viewing this that the
movement up and down for the lip of the cone is about 1/8 to
1/16 inch. it is not nearly as pronounced as that video.
3 - Hamel's tunnel - I'm not sure what this is about.
4 - the GMD device - the outer rim magnets need to be slightly
below the wing magnets to provide lift. take a couple of
magnets and bring them together with like poles. then raise
one slightly above the other and see that you can come closer
that way, than if they are at the same height. this provides
lift to the wings. it is the same in the 3 cone device. the
outer rim of magnets is just a bit lower than the cone rim
magnets to allow them to float.
