Self spining magnet rotor.

That's pretty clever (the earliest video 6 years ago shows the principle of operation, which is not clear in the other vids).

You say, though, that it "is not just powered by the actuator."
What else is powering it, then, and do you have any evidence that it is not powered "just" by the speaker-driven actuator?

Why don't you just use a cam or other mechanical linkage running off the rotor, to drive the speaker cone, and then instead of pumping power into the speaker coil, you can get power _out_ of it. Right?

Thank you Tinsel.

"What else is powering it,..."

As I said, the permanent magnetic fields of the magnets (in the stator and rotor) provide the remainder of rotational torque in the motor.  Since a magnetic field can not be visually displayed, it will not be possible to show visual evidence, without a confidential demonstration (to protect the IP). 

Mechanical cam actuation is not practical, because a mechanical design lacks precision (is too sloppy) and would greatly limit motor performance because it lacks precision.  Therefore, use of a small amount of power to enable better precision performance of the motor is called for.

This latest video of Gotuluc's demonstrates the practicality of overunity:

Imagine a speaker under the waving magnet hammer oscillator. Gotoluc demonstrates more force per milli amp with the addition of magnets. I believe it's fair to project that kind of gain.

@Liberty: I hate to always sound so negative... but I'll wager that all the power that rotates the rotor does in fact come from the electrical energy you are supplying to the actuator speaker coil. Since you are unwilling to show evidence to the contrary... maybe I'll just have to build one myself and do some measurements I can rely on.
The reason you don't use my cam-linkage idea is because you know it won't work, and not because of lack of precision. Any competent machinist can work to precision levels far above your ability in gluing a post to a speaker cone, and the magnetic fields you are working with are far sloppier than a precise mechanical linkage would be.
Your magnetic linkage has many real advantages over a mechanical crank-conrod arrangement, and a few disadvantages, but it does not produce any extra energy above what you are supplying to the speaker coil.

@synchro: Is Gotoluc claiming overunity performance from his device?

I respect your negative opinion, and understand it because of a lack of knowledge and understanding of new technology.
