Probably the real-deal Gunther.  These guys have figured out how to "not destroy the dipole".

I have been following Infinity SAV since their first little prototype device.

My hunch is their concept will also work with non-mechanical devices as well.  It's all about doing the right thing with the back EMF.
Quote from Infinity SAV
The Magnetic Generator is complex system with an organized structural arrangement of permanent magnets and bifilar coils and PCB controller with a specially designed software that are used to generate and dispense electrical energy.

Initial start is performed by a battery or any other external source of energy to help motor reach needed RPM. After that the external source can be disconnected.
 The device is able to operate in autonomous mode and maintain its RPM regardless of amount of useful energy being consumed.

The magnetic generator MG10 consists of 60 neodymium magnets and 60 bifilar coils. The constructional feature that enables generating electrical energy is the precise angular alignment of the coils and magnets inside the drum and the switching regulations to suppress back EMF and effectively collect accumulated energy inside the electromagnets (coils). As a magnet starts approaching a coil, at a certain point the voltage of the coil increases along with the amount of charge it can transfer. Once the switching regulator detects the maximum voltage of the coil, it switches off the coil. The magnetic field of the coil that has been formed after excitation of the coil will tend to collapse generating a back EMF in the coil windings.
 The designed software of the generator is able to suppress the parasitic current and transform it into usable electrical energy that can be utilized by the end user.
And you can take your chances and pre-order one right now:

You know, ill tell you somthing you might've not known.

How do you over come the CEMF lenz law?

Bifilar coils... yep thats what there using...

Think about how that would work... makes good sence to me... things just have to be right...

So watch this video carefully and take note of its simplicity:

Suppose we had bifilar wound coils and left them open circuit.  When the magnet passes by, what if a charge was developed between the two windings.  When the magnet just crosses TDC, we connect the two windings and discharge this potential much like a capacitor into a load.  In the process of extracting this dielectric energy, it also creates a back EMF that is in opposition magnetically to the permanent magnet that just passed by, creating a repelling force that pushes the rotor.  Could it be this simple?

Also note the count of magnets to coils.  Fifty five magnets; fifty coils, five rows.  So in each row there is eleven magnets and ten coils.  Calculating the cogging factor you get 0.909090909090...  Kind of strange number don't you think?  How this keeps the coils primed and asymmetrical is probably something to take notice of.  I'm guessing each column links the five coils together.  There's only two wires per column, but notice the "possible" polarity colors of the wires (red & black), again not symmetrical.

It just all looks very fundamental to me and obviously can be scaled up to higher output.  This prototype is clearly a proof of concept and a usable one at that.

I want to make one of these coils.

Any ideas how they are wound?

My feeling is they are indeed bifilar, but somehow asymmetric so that a charge develops between the two conductors when approached by a magnetic field.  A magnetically chargeable capacitor so to speak.  Figure out that mystery and we are well on our way.

Focus on that picture.  Notice anything interesting on the inside of those coils?  The little black dots on the leading edge of each coil?

What do you bet those are ferrite beads.  And if I was a guessing man, I'd guess one strand of the bifilar winding goes around the bead and the other does not.  That's where the asymmetry comes from needed to create a charge between the two windings.

Need more evidence?

Notice there are 11 magnets and 10 coils per row.  Why?

Because with ferrite beads in there, you would have significant cogging, but only if the magnet count matches the coil count; it doesn't.  That's how he is able to just gently turn the shaft and away the thing goes.

Also notice the direction he turns the shaft.  He always turns it the same direction because with those beads in there, the motor is directional.  The magnet must approach the ferrite bead before the main coil loop.

I'm thinking each coil is setup something like this:
