Thanks for your understanding.

I made a last measurement with the same setup as in the last video and setup the power into the bulb to exactly measure 1W (500mW * 2).
Then i measured the input voltage across the L3 with the blue probe and measured the current there, see the picture for the outcome.
We have 581mW * 2 = 1.162W into the core/coil.

The PA is an XT800.2  automotiv MOSFET amplifier class AB at max. 50KHz.

Seems to be close but no cigar.


Any idea how much power you can push through L3 ?
What is the watt ratting of light bulb in the output side ? It seems to be so bright that adding another should not be a problem. In my setup I put the 8 watt bulb first and then connected the 10 watt bulb on live circuit. Result was that 8 watt bulb dimmed a little when 10 watt bulb was lit. Nothing visible in input side 5 watt bulb.


As for the drilling, there needs to be something inside the toroid. When the blade comes through it will crack the epoxy unless there is wood or plastic taking the pressure from the drill. It should be interesting project, the coils on the holes behave funny. Magnetic loops are formed but not where one might expect. They always oppose the source even if there is 'free' path around the core. Flux seem to want balance in the core. This is why Gunderson uses magnets I quess': they form 'magnetic DC' bias in the core and then magnetic loops are formed elsewhere.

Comparing the brightness of the output bulb to the brightness of the input bulb is tantamount to comparing Watts to Amps.
Meaningless mostly...

As I understand the patent of the 2nd device, those magnets are merely sources of the vertical MMF. 
The author writes that the flux of these magnets (green) can take two paths through the core (see Fig.3 in the patent) and the primary coil (coils) are a source of the controlling horizontal MMF and flux (blue) that switches the green flux between two alternate paths of equal reluctance.

The blue horizontal flux closes circumferentially through the core, while the green flux passes vertically/diagonally through the core but closes through air, which is bad, unless a low reluctance path is provided for it by an external permeable spool or pot core.

No, no idea what the max. value will be.
The watt ratings of these bulbs are 0.6W at 6V, so pushing them a lot with 1W.

Good info,  thanks.

Here current and voltage are in the same phase in L3 because of resonance condition in the output. Does it make comparison any more meaningful in this case ?


Putting a diode bridge without smoothing cap in the input side should also make comparison easier ?

No, because the I-V phase relationship is not the problem in this case.
The problem with the power indicator on the input side is the uneven power sharing between the indicator and the DUT (a 2-device problem according to MPTT ) ...even if the DUT is a purely resistive load ( I & V in-phase).

On the output side this problem does not exist because the power indicator is the output DUT (a 1 resistive device problem).

Check out Igors new vid.

This guy is good..  What the heck is going on when he shorts the toroid?   That 1 wire of the system going through the toroid cant have that much induction for the shorting of the toroid winding to reduce the inductance of the single wire much hmm?

Hmm, ok. The single wire going through the toroid core is where the road block is, and shorting the toroid coil decreases that inductance and just allows the circuit to work as if the toroid core were not there. ;)


I wonder if he knows that?

He is using same kind of connection for primary as I am using for secondaries. I have the experimental caduceus wound core which I can use to test just like in the patent. It has four coils of exactly same length. I can also try low and higher voltages.


I think what is deliberately missing is the parallel capacitor in the primary, or he is using such a high frequency that cap is not needed as the primary coils give the necessary capacitance.


Not sure when I have time to test but I will test it eventually.

Some pictures, E-I core in progress, all L2 coils 45 turns of 0.3 mm wire. L1 coil about 110 turns.[/size]


Picture of a system in action. Middle L2 coil 20 turns of 0.75 mm wire, outer L2 coils 45 turns of 0.3mm wire. I made isolated tank circuit from middle L2 coil using 6 uf worth of capacitors, then a series resonant circuit from outer coils using 3 uf capacitors. The outer L2 coils were connected in parallel. Combined LC in both circuits should be the same for best result so 23 turns of middle L2 would have been correct, or 40 turns in outer coils.


What happened is this:
Input 6 watt halogen brightness remained the same with or without load (10 and 8 watt halogen bulbs). Shorting the output also seemed to have no effect.
Adding capacitors bring resonant frequency down and increase output power.
My E-I core was not perfect, it initially had an air gap which I tried to remove by grinding.
I did not achieve resonance since my equipment is limited to 20 KHz. I would have needed more capacitors to bring resonant frequency down.
I used 10 meters of 0.31 mm wire as L1. First I wound one layer (45 turns) and rest of wire was unused, still part of L1. Input side bulb lit brightly and less light on the output side. Next I completed the rest of wire so there was about 110 turns in L1 and result is what is shown in the picture. Adding more turns in L1 until input current was minimized works best.


I tested also using same amount of turns (45) in all L2 coils but it was not as good. Next I tested using thicker 0.7 mm wire, 20 turns in every coil. I got the same effect but I did not have enough capacitors to bring resonance frequency below 20 kHz.


This also seemed to work without series caps in the output, just isolated tank circuit and outer output coils directly to load (parallel connected as before). There is also option to connect paralleled side L2 coils in series with capacitor and middle coil which has parallel capacitor.


One test was 200 turns in every L2 coil. I got resonance using 0.5 uf cap but not as much light at output.


Without scope it is impossible to say what is the best option, more experimentation is needed here. This seems to work best when using high impedance input L1 coil and low impedance and high capacitance in the L2 side. Then look for resonance.


I hope this information encourages someone else to try this. My input was from audio amplifier, sine wave AC output as before. Pulsing did not work well.

For a certainty, to achieve overunity in applying Motionless Motor Generator Design, Square Core or Toroid must be applied, Twisted Serially Connected Multifillar Wire must be applied in Primary, High Voltage Must be applied in Primary, Thick Gauge Must be applied in the splited secondary(as thick as you can get), The primary must be driven with High Frequency(optional if you apply heavy Multifillar Wire), High Frequency Core Must be applied.
When you negate Lenz with your winding style, you have then open the gate for prospective endless inflow of Energy.
By prospective it means that Lenz negation is not enough to achieve overunity. You MUST obey other accocited rules which I have aforementioned.

The application of High Voltage is Necessary because in addition to  high frequency drive, it hejlps drive the air-base electrons Nuts as the Primary will be able to now draw them to the partnered output coils MASSIVELY. Once those enticed Radiant electrons arrived you must be ready to give them there proper place to place the Goodies theynbring along for you which means you must use Very Thick Gauge in the Splited oppositely wound secondaries.

The application of High Frequency will mandate a Cool running very blow amp draw primary.

The primary is best wound in Inverter transformer way though optional.

Make sure you use Big or Large Ferrite C-Cores so as avoid Saturation as the Flux from your HV HF driven Multifillar Wire wire wound Primary will be Enormous.

The essence of of Enormous Flux is that, the Free Air base Electrons will be superbly Enticed and "STICK"/to your Secondaries because you are FEEDING THEM WELL as you drive them higher with High. Speed or Frequency. This Air-base electrons like no dull moments at all.

Just create the appropriate Environment for them and we what they will do for you.

You can do better.
