Create perpetual energy - almost

Is perpetual energy possible?

The debate rages on. And they just keep trying.

This particular device may not be perpetual, but it is far more efficient than, say a homopolar motor.

The magnet in this device, the creation of our friend HowieD, propels the rotation, powering the LED.

Since magnetic energy is constant, an argument that it is perpetual seems ostensibly reasonable....that is until one considers that friction will inevitably kill the magnet.

Ok, ok... our minds are blown, too.
