We all know this experiment is an achievement of great importance. I start to replicate it here:
The currents are the pink (L2) and yellow(L3) traces. The dark blue trace is the input signal with the probe ground disconnected. That's why it looks so weird.
L2 field decays and causes EM induction in L3. Then L3 decays and causes EM induction in L2.
I'll be back.
Notice the power supply and switch from Vidura. Fantastic tools! I've never used anything like them.
Hey, man, I understand, asymmetrical regauging on both traces.
Let's see some more results from fiddling:
I have more results coming soon.
Also, notice I'm not using the ATX supply for powering the power switch any more. It introduces a lot of noise on the oscilloscope traces. Plain old batteries are cheap and keep the traces clean.
Awesome! Excellent replication! EVERYTHING I see is Good! Little bit of interference, perhaps switching harmonics or something? But wave shape is all good!
Learn as much as you can with this CD. Excellent work!
Hey, man, the interference is because I use the 5v output of my linear power supply for feeding the power module while the main output of the power supply feeds L1. If I use batteries for the power module, the interference drops. I ran out of batteries for the moment. Question: we see current flowing in both POCs during the off time and the diode in series with L2 is getting hot; why is the bulb not at maximum? In fact, I replaced the bulb with a 5/20w, 12v and it lights up very weakly. Next up, we must see what the output voltage is and how we can increase it.

If I may suggest a few reasonable sized Caps on the output of your Power Supply and a small one, say 5000uf or so and a 100nf or so, it may remove the Noise. Something like this:
It looks to me that the Fet may actually be triggering, turning on, during these harmonics? Possibly? If so, increasing your input.

Yes both POC's must carry a current, and the Currents / Magnetic Fields, must oppose. The Diode is effectively a very low Resistance uni-directional Load. Current can only travel in one way and when it does, the Energy Transformation is converted to Heat as you know.
Both POC's have low to zero Impedance during the On Time.
Not so at Off Time.
Impedance ( Z ) is what gives us a slower decay in Magnetic Fields. This is the Power "Generational" Phase, if you like. Output when no input is on, a disconnected Input from the System.
With too much Impedance, Power is reduced. However, I = V / R, so our Output Current ( I ) is directly proportional to the Output Voltage ( V ) and the Output Resistance ( R ). This you already know, you pointed out here:
Next up, we must see what the output voltage is and how we can increase it.
The Voltage ( V ) gained during the Input Phase, On Time ( tOn ), linearly decays over Time ( t ), so the average Voltage ( VAverage ), will be approximately: VMAX / 2 over the duration. Roughly.
So our Maximum Voltage is not the Voltage we see over time, that our Load see's over the duration.
Capacitors on the Output is an option, to smooth the Output over time. Similar to your noise problem above. Realistically, increasing the Voltage Potential, getting the Potential up higher, faster, over a shorter tON period. This gives us a greater Average Output Voltage, and thus an Output Current.
I'll try all the things above, thanks.
Here is my latest progress taking you advice into account:
The above experiment flattens the output voltage, which may affect the time when the POCs interract. Here is the proof:
CD Excellent work!
The Input Coil is the Signal Coil, its what brings the Output Coils into Resonance. The Length of the Coil, Wire Gauge, Frequency and Duty Cycle are all important.
If we took 2x Coils, in front of us. These Coils need the same Magnetic Resonance as The Mr Preva Experiment.
We must find the ideal drive method.
A Coil must be selected that can drive the input Frequency and Duty Cycle at the maximum efficiency.
Sometimes reducing the Turns, reducing the Duty Cycle and adjusting Frequency to suit, will be an option for increasing the Output. Finding where the Output Voltage reaches the highest point.
Excellent work my friend!
I'll take each and every advice into consideration.
I'm taking small steps, not to miss something important.
Let's see when is the output voltage raising and what's causing it to increase. I'm using the MATH A-B function of the 'scope:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
