somebody please take a look at this asap! http://youtube.com/watch?v=yVkKvgKYkjo

It says:
We observed 3 shared in common geometric magnets ready to 120? an axis that rolls by two curved tracks. Whenever one of magnets happens through over the black box where is an electromagnet with a derivation and a transistor, this last raisin to the saturation state, allowing the passage of current by the electromagnet. This causes the appearance of a magnetic field that repels to each one of movable magnets, giving the necessary impulse them like making the cycle indefinitely ... (more)
So it seems it is powered by a battery in the blackbox ?
There also appears to be some clothes behind the device that could be covering an elecrtical input.

hmmm
