Resonance and high frequency

[Classic]

@kampen , did you just used an AI for the suggestions above ? I can recognise a pattern there

I always ask everyone to be cautious when working with electricity and yes safety is first ... but I can hold in my bare hands any part of the circuit non rectified ... I can make connections through the water and hold the wires with bare hands in the water without high voltage added.

Adjusting with capacitors ? A self resonant pancake coil ? Really ? The system MUST comply with Pinput =P output ? WTF ? Tight coupling ? Tight capacitive coupling ?

Hi Classic, i cannot promise I'll be able to replicate your exact build, but I'd be grateful if you could make some videos, even if short. The videos you made previously with the ZVS, pancake coils and an iron were very helpful. 

Before the end of the year I was working on two Don Smith related concepts:
Sympathetic resonance coupling - LC circuits tuned at the same frequency should couple with each other for higher output. I did it with three coils at around 2MHz, the coils have Q of about 300. I have not finished doing all the experiments I wanted, but so far I have been unsuccessful. More coils are needed I think. Or perhaps I still have something to understand to make it work. Because so far if I load any of the coils, the output of all the coils goes down. If the coils are not loaded and put close together, the output of all coils goes up, but what use is that if I cannot use the power.
1/4 wavelength primary, 1/1 wavelength secondary - when using a 1/4 wavelength primary and at 1/4 frequency, it should be possible to ring the secondary with reduced duty cycle. I was able to get down to 9 percent duty cycle and still get the same power output. It was tricky to get it right, I made mistakes in computing and cutting the right lengths of wire. But yeah, that works.

What I want to focus on next is high voltage. At least 1 kV with earth grounding to see the point when the electrons harvested from the ground will start bringing the amperage.

@kloakez , I can only recommend to stick with the original setup disclosed by "what if I did this ..." youtube channel. Also, consider adjustable resistor on ground connection if you want to harvest electrons from ground ... in conjunction with a spark gap on positive feed.

At least 1.5 sqmm copper speaker wire is a must ... with my setup I am not able to drive 4 pancake coil as resistance is more than double with 0.75 sqmm multistrand copper wire. I can only use 3 coils for output and not taking full advantage of 1/4 wave amplification ... still plenty power available.

I just finished a test, looking for standing waves in copper pipe 18 mm diameter 2 m long used as resonator ... no standing waves. Voltage vary indeed but mostly due to position of single output wire. Using 10 turns coil slightly lose to allow sliding along the pipe ... DC voltage (the only voltage I can read with my cheap multimeter) vary between 15 and 18 v and the higher voltage is reached when output wire is perpendicular on pipe.
Easy to figure out now that I need another pancake coil placed on resonating pipe to capture all available electric current displaced.

I have used a single coil single layer various lengths with highest DC voltage upto 260 V but, indeed the voltage drop under load but the power available drops as well ... reduce number of turns yield more power indeed with less voltage (160 V). It seems that I can place many coils along the pipe and each of them will get the same power ... testing in progress.

Before I will use a flyback transformer I need to figure out best method to capture and find out if multiple coils can be used in parallel ... but, I run out of rectifiers ... so I need to use a single rectifier with identical coils in parallel. No great but, this is all I got.

So, in terms of output we can use dc/dc buck booster ... the cheap one that I have available only takes 36 V maximum ... so, I am limited to make little pickup coils. I have made a short on my channel using a solar charge controller (is toasted now) but, without isolation everything drops down to battery voltage even if in that output is enough power to blow up a 55w car headlight.

For isolation using Lorrie Matchett method worth to explore if you have handy some aluminium tubes to compare against copper tube, although Don Smith using soft iron rod or plasma tube ... millions of options and I guess each one will yield a different electric field in terms of strength and size ... but this will vary upon voltage used in providing circuit.

I prefer to use bifilar coils as I can dispense with the need for tuning capacitors and coils can store enormous power in this way, ready to be delivered to the loads or to maintain the oscillating electric field in resonator.

I have found that using Lorrie Matchett method help to tame frequency and is not reflected back in providing circuit if 700-800 mm gap between resonator and providing circuit.

Even very small power on isolated output can drive easy tens of leds in series ... but there is plenty people doing this ... no point to repeat as I aim to deliver some decent power. A cfl bulb of 11w powered with DC at 160 V, drop voltage to 39-58 V fluctuating continuous due to its electronic ballast and only flicker dim. 28 W incandescent bulb drops voltage to 0.35 V constant, obvious no light comes out. Interesting, cfl bulb rise frequency only to 85khz (I hope I remember correct), while incandescent bulb maintain same frequency of 17.6 Khz.

Also, despite 160 Vdc (approx 220v ac at 17.6 khz) I can hold the resonator with bare hands and when I touch it voltage goes up above 200 Vdc.

Somehow, I have a feeling that Don Smith similar setup or all of them employs this method where only the hot wire is connected for real ... one wire transmission.

May worth to consider lose coupling, less power available on output but without loading the input ... than you can figure out what to do ... you only need a certain little power on the output of that is enough to drive another setup to deliver the power you want.

I have taken a break from my batteries but they are a feasible option for a free constant input for this type of circuit or similar. While I am highly consider main circuit oscillator with just one transistor from "what if I did this ..." it was a great mistake to use his circuit with the grid, must be used with batteries as it really is powerful.

Ok, enough for the moment, back to experiment now.

Think about why NCV function of a multimeter work without taking power from grid and only works with hot line is the circuit is open.
