I have started this thread to put my construction and test of the cell all in the same thread.   For my projects I keep my notes in word document, so it is easy for me to find things and to look back on what I have done.  I include things that work and things that did not and the tools I have used.  The attached document converted to a PDF is the one for my build of the cell including the acrylic tube and end caps and capacitor tubes.  Besides information on the construction, I will include tests of the capacitors.  As I have posted some of earlier steps in this process in other threads, I will not be repeating those steps in this tread as they are already in the attachment.   I will be updating the attachment with new information as well as posting it in thread below.

I made 6 tube sets 5 ½” outer and 6” inner and checked capacitance on each of them in air, distilled water and city tap water.  That information has already been posted and in document and I will not repeat it here.  Post below with cover testing of 8 ½” outer and 9” inner tubes. 

TESTS ON LONGER TUBE
I wanted to see how length of tube effected capacitance of using the 8.5” outer tube and the 9” inner tube and doing taking some more reading.  As I did not want to cut multiple lengths, I decided to slide the inner tube into the outer tube.
 
To do this test I make what I call a slider spacer which fits on end of inner tube and has fins that center inner tube inside outer tube.  I already had a spacer for the outside end I had made from earlier tests.

Note: When doing this I found that tube still had a sight ring from using pipe cutter on each end.  I used pipe reamer to remove did not do good enough job initially.
Items used during testing  First picture shows items used and second test setup, Outer tube connection is through setup screw with stainless spring.

Initial test results

Length inserted in distilled water      in air
5.0”                             46.45pF
5.5”          10.16nF                           50.06pF
6.0”         11.94nF            55.45pF
6.5”         13.68nF            61.19pF
7.0”         15.27nF            65.02pF
7.5”         17.84nF            69.62pF
8.0”         18.82nF            72.21pF
8.5”         20.68nF            76.23pF
9.0”                             77.82pF
As expect this acts as a variable capacitor value changes approximately 4pF ever 1/2 inch or air.
Note:  The 9” should be the same as the 8.5” as inner tube is now sticking out the bottom.
Note:  Meter was reset before for each reading as recommended in manual.
Note:  Need to take care as putting hand close to test setup raise reading.

Cell outer tube and parts

1-   12” acrylic tube 4” ID 4.5” OD from McMasters (Note: They have 2 versions of this tube this one and on that has 4” ID and 4.25” OD. I choose the large as it fits standard DWV fittings)
2-   4” DWV end connector one for each end slip connector with other end threaded (2) fits standard DWV pipe which has OD of 4 1/2”
3-   Flat screw cap for bottom has slot to tighten
4-   Screw cap for top has raised square nut to tighten
5-   3D printed holder for seven I/2” tubes
6-   1.5”x ¼” x 20 stainless hex set screw,  End of screw drilled with 3mm hole to hold spring
7-   10mm x 3mm stainless spring
8-   ¼” x 20 Stainless steel lock nut

Tried to show picture of cell loosely assemble but it kept timing out

When getting ready to add the document to this tread I took another look at the table below

After taking the capacitance reading above, I was back to the same question I had a when I first studied this table a long time ago.  How where readings taken at specific frequencies as meter, I use selects a frequency.   I did so more reading and found several articles on how to do that using a signal generator to set frequency and power level.  Part of reason I had avoided building cell as I did not and still do have a signal generator.

Reason I was doing this is I want to know what size tube I need to give results at 5khz.

I have been working mostly on basis of open tube resonance calculation. Im not sure if your approach is different, but, it might be insightful. http://www.gigaphysics.com/swift_resonance.html although I prefer imperical measurement.

I always wondered when I was looking at Joe Cell years ago if he had perfect pitch and use to make cell resonate.  Not sure if that is case here based on test on long tube and moving it in and out to change capacitance I wonder if that is the purpose of the slots in the picture?

I think meyers smaller cell may be in acoustic resonance, but octave spaced. I am trying to replicate it now to test this theory. It seems logical to me that the older large tube design, the slots were there to fine tune tuning but likely to same frequency. At least, this is my current thread of understanding. Cutting slots in tube would be a way to tune resonant frequency, that is for sure, so I believe that would be the likely purpose. It should be fairly straightforward to try to mimic based on the photograph measurements to confirm/deny. I have an xls calculator i will look for to aid in estimations

Could be possible, the right resonance could help weaken the bonds between the oxygen and hydrogen, I read in a popular science magazine years ago they figured out a way to do this and were actually able to light the water on fire, no idea whatever happened to that.

Holy crap I actually found the article online.... https://www.popularmechanics.com/science/a2840/4271398/ guess it was popular mechanics instead. He was apparently trying to use radio waves to treat cancer and ended up seperating oxygen and hydrogen out of salt water which could be lit on fire. Problem is he never claimed more energy out than in... so I guess the frequency ate up a lot of power? I don't see why it would though.

I definitely think resonance and harmonics of both EMF and Sound Waves could be used in circuitry to increase power outputs. EMF Resonance is essentially how wireless chargers work. So imagine if you had inductors setup to cause a cascade of resonance taking the input signal and amplifying it through the inductors as the EMF's all interacted. Kind of like Teslas supposed "Earth Quake Machine" except with Electromagnetic Fields.

Thanks, I enjoyed that.
