It's easy to design a system that perpetually just cycles energy through a system in a loop. The problem is that it's never actually making new energy, it's just moving energy that was already there around in the system. That's what happens here

So, in an absolutely ideal, flawless implementation it would just be able to keep going in a cycle forever. However, every tiny amount of friction will permanently extract energy from the cycle. Even worse is if you try to actually make the system perform "work" by extracting energy intentionally. Then the energy will run out pretty fast and it will stop working.

Ultimately, pretty much every idea for a perpetual motion device you'll find is just an unnecessarily convoluted variation of a flywheel.
