The disks on the floor are magnets all with the same polarity facing up.
The magnet on the pendulum has the opposite polarity facing up so they repel each other.
This trick works better if you conceal the base magnets with a stiff sheet of material.
The hard part is get the height of the pendulum magnet and the positioning of the base magnets exactly right to maximize the time of the "random" movement. The anchor point at the top must also be loose to allow slight upward movements of the pendulum.
In time, it will always stop in one spot - unless:

1. There is air flowing past the pendulum.
2. There are hidden electromagnets in the base or the tower which are pulsed intermittently to kick the pendulum.
(In which the base magnets also act as a distraction to the observer).
3. A permanent magnet is being moved in the base, or the tower or out of shot of the camera.
4. There are tiny movements induced in the hook supporting the pendulum.

Can anyone here figure another way to make it move indefinitely?

#1 There appears to be a larger magnet near the cardboard base. Not sure why. It also doesn't seem to reach the magnets that are closer to the viewers (ostensibly because the magnetic force is not strong enough).

1) I wonder if a larger magnet directly under the hanging rod (with the opposing polarity magnet) would keep it from settling indefinitely?

2) Maybe moving the base magnets closer together whereby eliminating "catch and hold" zones?

3) Remove the magnets down the center creating a magnet void channel (or maybe even off-center) effectually having opposing forces on both sides of it's resting zone?

4) Just one magnet directly under the hanging rod of the right size and distance?

I'm thinking 4) is most probable.

That's all I got and my brain is starting to hurt. ;)

BTW, off topic. The lighting in this video is really nice. Very even and the colors are simple and neutral. Very pleasing the eyes.

I don't know why we don't see these in fields instead of those fecking wind turbines I'm sure they could be made to generate electricity and they could employ someone on minimum wage to sit in a little shed next to it, to give it a push whenever it stopped on one magnet. 8-)

#6 This setup does not generate any energy whatsoever.
It consumes energy - you have to raise the pendulum to get motion going.
