attraction is what i used mainly for one of the driver coils that used the side magnets to trigger.the other one having the hall on top used attraction too but a bit of replusion at the same time.

@David70 : thank you for sharing that. Many people managed to get the effect for 1 coil. But the output they got was smaller then the input. And adding a second coil did not help. We will wait for your test results regarding the discoveries you might make in the future.
By the way, any info on the output ? You mentioned the input but mostly nothing of the output.

@mariuscivic : we are doomed ? Sounds like there is no magic ? instead of output the input power gets converted into rotation speed ?

The output can be looked at as a combination of mecahnical torque from the rotor and electrical from the generator. One affects the other and no variable can change without affecting other variables. Tune output to what you want, either higher electrical or higher mechanical. The machine will seek a balance that can even be influenced by nature in that there can be speed variations between day and night running.

Hi,
about a week ago I called Romero for the second time and asked him to point me to a direction where I can get close to OU or even OU and no connection to Muller as I understand we will never get more from him.He was kind enough to give me some indications that I folowed and I can tell you all my results.
What he said is to have a small rotor with magnets, any orientation, NN, SS or NS but to make sure I have at least 2.5 times the magnet diameter more space for the gap in between the each magnet, and 2 air core coils. He said this way I have nothing to slow down the rotor and is like i don't even have the coils there.
To drive the coil he pointed to a circuit that was posted by someone some pages back, circuit that was used initially to drive a pendulum.He said to keep the circuit as is and just change the transistors with BD139 and BD140 then if I have a scope look at the driving coil and drive it with no more than 6-7 volts.This circuit when in Off position recovers some of the BEMF even without a diode for that, that is strange to me.
I built the rotor, 8 magnets in NS orientation and the circuit and tested, it is only using 16ma to drive the rotor with 6 volts input. at about 900RPM.
Now the second part is how to get some power out without affecting the input or the rpm.
I made a bifillar coil 400 turns, I think is 0.3mm and connected like tesla suggested, the end of the first going to the begining of the second,this is what Romero suggested.
He also suggested something that I never heard, make a FWBR from superbright 4 LED's.I did that and connected to the coil and have a capacitor from one of the coil wires to the bridge.He said that I will need to try different capacitors because it depends on the coil.In my case I use 2 times 0.22uf/250v, in parallel.At the output of the bridge he suggested to connect a 1k potentiometer and start having it at the middle.
Now the fun started, I have the rotor in action and the LED's from the bridge are lit in sequence when I have slow speed, after that at higher speed all LED's are ON.
The first thing is that the input oscilates slightly from 16ma to 15ma but without the bridge it stays at 16ma.Adjusting the potentiometer I get slightly more speed and brightness and input goes to 14ma.
From here Romero said that I can add more LED's in parallel or make a chain of LED's then from 4 identical chains build the FWBR.I don't have enough LED's to make that experiment now but I wil get some.For me even getting cheap LED's is not easy, my income is a small pension that I need to look after.
In the final Romero said that making a FWBR and for each segment I add a resistor or a coil will open a path to even more discoveries. I am not sure he was talking about using normal diodes or LED's in this configuration.
I am posting this here and maybe someone can do the same build and confirm all  other suggestions

David

Thank you very much for sharing that with us, I like the FWBR made of leds very much because it shows me better whats going on

@Erik:

Thanks for the reference. I did remember that statement too and wondered why he would attract and repel (sometimes).

Now I think at least two factors help minimize Lenz's law. (1) The amount of time the drive coils are turned on (minimized) so as not to inject too much current and hence drag but enough to drive the rotor forward until the next hall sensor picks up the pace and those halls operate mutually exclusive. That's why his little magnets are real small just enough to activate @TDC and then shuts off the driver . (2) A rotor speed up is only good if the maximum magnetic flux can be harvested at the pick up coils. Running the rotor too fast picks up almost nothing - there is a fine balance between Input power, rotor speed  and RLC tuning. I noticed that adding a second pick up coil marginally improves the output charge collection, i.e the voltage rises at the large cap. and current level (bulb load) increases; of course the rotor speed decreases. But it is always way below the needed percentage needed. Well, maybe Romero use a scheme where he periodically slowed down the rotor to harvest the maximum charges and then pumping the next Hall pulse just to maintain the needed rotation speed essentially creating a biasing condition in his startup DC condition needing 900mA? The addition of the 100 ohm current limiting resistor to the TIP42C helps a little but it will be a few milliamps and not a factor in the 900 mA. Even in my own Hall sensor circuit which is slightly different, the whole circuit running uses an average current of less that 30mA even with a LED indicator included.
I am puzzled by the 900 mA because Romero's no load speed cannot be more than 1500 RPM judging from the video and with those components, the 'normal' current should not be more than 500 to 600mA. I think but I could be wrong. So, this extra current could be used to periodically slow down the rotor at resonance to pick up the most magnetic flux? The way it could be done is to bias some of the pickup coils to reverse(repel) the normal forward direction of the rotor. Just my guess.

The rotor magnets do what they need to do and the stator magnets add the balancing bias. Other factors like air gap spacing between rotor magnets and coils also contribute to the total energy equation. So, we have a bunch of questions and thank you all for listening to my babbling!

cheers
