X,
Definitely food for thought!
The tweezers we're a nice touch!

Thanks

vid not mine, 

Each domino's has its own PE when they kept straight. By releasing the PE of one small domino its converted KE helps the other domino to change its P.E to KE.So nothing special in this.

If it happens in the otherway like , smallest domino's loss of PE help the next domino to gain its PE , then loss of PE on this domino help the next to gain its PE then its really unbelivable. By doing this all dominos will loss there PE, the final one has a PE.Can it possible. It cannnot.

@Cloxxki,

Wonder if you saw my attempt at building the gravity wheel: http://www.overunity.com/index.php?topic=7150.msg229719#msg229719 and  http://www.overunity.com/index.php?topic=7150.msg229720#msg229720. As you can see, unlike Abeling's the ramp is inbetween the two wheels and the steel ball are only lying on the edges of the slots thus decreasing the friction significantly. There's one difficult constructional problem, though. As you can see, the way it's done this construction only allows for the lower part of the ramp to be easily positioned. The upper part of the ramp, needed to form the entire quasi-elliptic track, is very difficult to hold in place. Any  simple way of attaching it stands in the way of the upcoming or downward going balls. Any ideas how this difficulty can be overcome?
