Perpetual motion?

[Moontanman]

I know this can't be real but how do they get this to self start and speed up with no energy input?

Magnets, unless I completely misunderstood what those black rings are.

 Yes magnets but magnets shouldn't be able to make that ball not only self start but speed up with no external energy input.

When he puts the ball down, it appears he pushes it.

So that's how it seemingly started.

As for speeding up, I figured it had to do with it passing through magnetic fields.

If you could do that with no energy input then it should be possible to extract energy from the system. Hence perpetual motion..

The energy input is the magnetic potential energy.

Magnets won't remain magnetic forever. Every time the ball goes around, they lose some of their magnetic potential energy(It might be called something completely different.).  Eventually the field will become weaker and it'll stop.

But that isn’t what’s happening. You aren’t “draining” the field.

whatever is being added is happening off-camera

Camera might be mounted in such a way so that the scene is appearing stationary.

Ah, okay.

 

 

Looking at it now,  I see that the ball always accelerates at the same spot: Right where he pushed it.

Initially, he gave it enough of a push to make the ball go around in a circle, and he just keeps looping that.
