Hi Frank, You should be aware that back in the mid 90's, _many_ people were encouraged by Greg to build and test these devices. I was not one of them, preferring my own insanity to others, but some are still on Vo. These devices started with Emil Hartman as far as I can tell, and they do work as described. JLN has a good collection of others work on his site, check there. It's seductive for just that fact, that it does look like you can just tie the tail to the head and have a nice oroborus.
That said, no one to my knowledge was ever able to close the loop and return the ball to the starting position. Many ramps were put together in a loop, a looped track was used, and as I last suggested to Greg before he was given the boot, simply allowing the ball to run under the ramp. None of these things should work, by the C of E ( Church Of England???? No, Conservation of Energy, damnit! ) But they should be tried all the same. Not because I doubt in the C of E, but because few systems are really closed to the environment. The funny thing is, it looks like the only person _not_ to have built a smot was Greg himself. That makes me chuckle, it really does. K.
