This perpetual motion machine...

An oldie, but a goodie.

The main obstacle is centrifugal force.
If the device were to continue increasing in speed, the 'arms' would all fly out, and it would decelerate.

However, if a load was applied, the machine could stabilise.

Granted, it is a bit of a rough device, but the potential is there...

Another view of the same thing...

don't think this will work on its own.

i think it needs a little help, maybe if we apply a smot somewhere.

peace.

These perpetual motion toys accelerate until centrifugal force destroys the imbalance.

They need the speed to be regulated. Load is a useful regulator.

Start one by spinning it like mad, and it will stall.
Start one by gently tipping it into motion, and it will accelerate until it stalls.

The range is there to extract some energy, between zero and stall.

Just have to stop it over revving...

What one forgets, is that the momentum on the right side is the same as in the left side. It looks like the mass on left and right side is the same, but no.
