No, the energy comes from the bump the person gives it.

It's a cool, clever little way to keep an object spinning for
a long time, no more.  The magnet passing the coil which
curves to follow the arc induces a current in the coil, which
charges the cap, which then discharges through the large
coil at the bottom giving a little "umph" to the magnet.

Rinse, repeat.

It's just a very, very low loss system.  I find that my
enjoyment of the video was slightly tarnished by the
"over-unity" gibberish running in the background, but I'll
fight my urge to get further up onto the soapbox than that.
