Trawoeer Power Pyramid Version 12 - Electrical output from a homemade pyramid

@Pascuser . A very interesting video . I am pleased that you were able to use my idea of extending the inner coil wire to get a better SWR . The SWR would have probably less variable if , as I suggested , you used a quarter wavelength wire extending downwards from the braid of the coaxial cable . The main thing is that you now have your SWR at a safe level , and can continue with filling the sand . Good luck with your results , and I do hope that you will keep us informed .

@Neptune: thank you. I I used your idea. And I used too a wire connected to the copper tube and connected to the multimeter (its impedance was useful and I could achieve a SWR=1.1 at minimum).

I filled in the sand. I started with SWR=1.1 and while filling SWR was slowly growing up to 1.9 when finished, because the reactor capacitance was changing because of the sand.

I tried to measure the E-field radiated before filling, but the high frequency too high power currents were blocking my multimeters, there is a lot of power (50Watts measured on the Power meter when SWR=1.1 so power measurement is good).

Here videos (with comments in english):

Voltage AC and DC after filling with "charged" sand (comments in french but measurements are easily understandable on the video):

I can read AC  and DC voltages between copper tube and coil wire but it has no special meaning since it varies not much and when I let the wires go down on the ground I can have more voltage.

Depending where my multimeter is on my desk I can have 1.8volts or 0.5volts or 200mV. It depends, according to me, on the electromagnetic E-field radiating from devices in my room (50Hz current). I can't read something interesting with this measurement.

I realised this morning that I did not paid attention to the way I plugged the output of my signal on the reactor. I checked what I did and I did plug the mass output on the coil wire and the signal on the copper tube. So it has been charged the wrong way.

Before sanding again in the good way, I made a voltage measurement in the garden, far away from electromagnetic radiating devices. Here is what I had:

Then I plugged my output correctly, I emptied the reactor from its sand, made it cook 10 minutes again in the oven and used it again to fill in.

Here I could not use wire on the copper tube, if so the SWR was 3 with 1 meter wire and 5 with 2 meters wire; with the multimeter plugged on these wires it was more than 10. Without any connection I could achieve a SWR=1.5 or 1.6 approximately.

I filmed the filling:

Then I measured again in my garden the voltages, so we can have a comparison between reactors with a good way of charging and a bad way:

But nothing changes!

I can't have voltages values interesting to notice.

Very interesting experiments.
But the reactor may be because moisture it stand above the underground river.
What then?
And if I can run the fan how long it will last?

I finished the assembly of the pyramid, replication scale 1 of Thomas Trawoeger's one.

I detected again the node to use (Hartmann walls crossing above a water line). I feeled the node with my hand, eyes closed, as a small warm. I detected this warm in the hand just 2 centimeters besides the center of what should be the node, so it works!.

here picture attachments with the pyramid set-up.

Then videos to explain my tests:

For the moment nothing works.
As I never had millivolts, the sand charging should be the main cause. But why? I charged with 50 watts and a better adjustment of SWR than Thomas did (not to burn my amplifier) so with more power than him, and approximately the same frequency (channel 40 used and not channel 1 in 27MHz band).

I need Thomas's help to go further.

My node could be not so powerfull, but I had no millivolts, and this should occur, followinf Thomas' videos, although you are not on the correct point and not well oriented. So again, my sand charging is the black point that is in question.
