Tuning...

Romeros coils dont look machine wound. So if done in a neat fashion, tuning may not need be very hard. If hand wound and lumpy, both the inductance and capacitance could change quite a bit from coil to coil.

Mags

All reading MUST be taken back at the dump cap with the desired load in place. The dump cap is an important feature to the overal operation.

BTW JLN parametric pump and back end magnets lead to solid state version of this muller system and PRE-DATES Orbo or magnacoaster ideas by more than a decade.

OK, Guys...
After burning few transistors, fiddling with many ideas I finally got the damn thing to accelerate under load .
What we are looking for here is the perpetia type effect where an HV coil (or a high inductance coil) accelerates under a load.
I've got 2 bifilars (in series) as generators and I connected them in series to get a higher inductance - that didn't help much.
But then I thought of adding more inductance instead of capacitance so between the 2 coils I placed third coil as a choke.
It is not in the magnetic circuit and acts as a current delay type of coil only. The 3 coils together measure around 120 mH, the choke
coil is around 100 mH. I also added an AC cap of 6,8 uF in parallel like marius just did...
Now, up to certain speed this setup decelerates the rotor when I connect a small car light bulb but after a certain threshold,
in my case around 1600 RPM, when I connect the light bulb the rotor speeds up significantly...
I will make a video soon, stay tuned...

P.S. The only thing is that without the capacitor in parallel to the gen coils the rotor speed is faster...

you guys doing the and trifilars and quadfilars etc.,series-adding coils...
try taking out power only on the "third stage" of them....such as in a trifilar, you have six wire-leads since three wires wound up side by side...
so call the leads:
wire one Ain  and Bout
wire two Cin and Dout
wire three Ein and Fout
so as series adding is, connect Bout to Cin, and Dout to Ein...now there is trifilar coil.
now when you take out power form this coil only put the AC legs of FWBR onto "Dout to Ein" connection, and the Fout

Reason am suggsting this test, is that Ismael Aviso uses septfilars in his MEG machine (6 wires paraellell) and he told me somethign about the first "stage" will lug, the 2nd will lug, but "past" the third it wont lug...could be this works havent tried it so more hot air again but will be easy to check out if anyone wants to try it. Not sure he was talking about his sepfilars here, but assumed he was...
I got my rig running really nice now so can start testing stuff out
So today, I took the backemf/recoil out of the motor coil swtiching, and put it into the generator coils for test #1:
What I found is that a FWBR doesnt work for this, you need to use single diode or it wants to die so that is interesting...and found that one coil of the three "spare" gernator coils in my rig (only 5 coils per plate on mine and 3ohm coils) did give a little speed up tried all three coils in series nothing specatacular so best reslults were just a bit of speed up with jsut one coil

so concllusion is "you can" put the backemr/recoil right into some of the generator coils if you want to...

you cannot do it "direct" with no diode - you will need a diode to send it in correct polarity.
basically testing was: try it one way if it slows, flip around....this done  in both the diodes-direction and poliarty feed of coils.

Problem is the generator coils jsut are not setup in timing to do anything motor-wise becasue of the even vs odd thin, so shouldnt expect any big speed increase.
cconclusion on this, is that will need to put backemf/recil into cap first, then pulse cap into those coils just like a motor coil would get a pulse, with proper timing,  is way it will go in future if it goes that way - it will take afew quite a few more mosfets and halleffects to do this.

Also ran the power-supply (12V golf cart battery)  right into the 3 generator coils wired in series...this was interesing jsut a lilttle buit extra draw in one polarity through coils, and huge lug in other polarity so you can run the power supply int the generator coils "if you want" is conclulsion from that test...

Nice work!  Looking forward to your video.  Thanks!
