New videos found on youtube, tiny generator with 2 coils

[Tito L. Oracion]

miniturising energy source, impressive!!! 

nothing, i just want to induce this in your brain

This motor operates from a self-induced magnetic field from coils that repel the rotor consists of a magnet and a lower wheel with two weights to create inertia. As initial power source is connected to a battery that delivers 2.4 volts, which converts electric coils and magnets to rotate the coils induce her see an alternating current in the secondary winding of each coil carrying alternating current to the diodes that rectify DC pulsing, a condenser is connected to stabilize the current obtained more than 60 volts of power as a result. The coils act as chokes and how to transform your look.
Each coil has a double strand of wire, motor consumption is 100 mha. the speed is about 7000 rpm.

What I dont understand from his video his he talk about batteries, even show one but dont use them at all...

I think he should replace the small lithium cell with a capacitor before we make any conclusions. The design looks very simple, and should be easy to replicate for those with a little more than average skills in electronics.

You mean that one side is magnet and on the other side its a small lithium cell?

[Lakes]

Two magnets with something glued in the center between the two springs?

I would guess that its either a battery or a piezo.

It is quite clear that there is a battery cell the blue one on the bottom side in the first video (In the second video it is obvious that it is a lithium cell between the two springs). A regular lithium cell used in small cameras. On the top there is a cylindrical neodym magnet often used in brushless motors for RC planes. The flywheel is also from a brushless motor - probably an E-Flite brand motor. On this flywheel, there is magnets - if the red and blue colour is indicating South and North. There is pickup magnets on the top with very many windings, so the voltage will rise to 70V after the bridge rectifier and the charge capacitor. This is as far as I understand a clever design, but not overunity. The proof lays in the part where he by accident sort circuit the capacitor on the top. The RPM decrease, and never rise. A true OU device would increased RPM untill the friction prevents it to go faster. This device does not.

Because he uses a high RPM (Dremel) to start, it could be the start RPM is above the "friction" point you mention, so you could be right and wrong at the same time!
