First electrical power output from a Pyramid

[vipond50]

Hi Duff
Ok
From the converter Cap to Earth Ground = 78pF
Across the converter (Capacitor to converter frame = 0.001248uF

Hope that's what u wanted

Hi Vipond50, and everyone.Bill, the only problem I can forsee with a variable cap inside the pyramid, is that as yoy vary it, the centre of the overlapped area moves. For yor current experiments this may not matter, but inside the pyramid, the center of the effective cap must correspond with yje exact centre of the pyramid. It might be possible to build one where both sets of plates move to compensate.
                 Tell me bill, as you have built your converter, What diameter copper tube did you use, what sand? what is the source and diameter of your graphite rods? Are all joints soldered on tubes?
Is the tubes COMPLETELY filled with sand? Any output voltage?
Lots of questions, I know, but untill The Captain returns, Helping each other is all we have. 
Regards Ken

Hi K.
Well i'll do my best to relay what i have hanging here
Tubes = 1/2" copper, type used in household plumbing.
Sand = Silica sand blasting sand 36 grit primarly and  down to fine dust.
Sand Level = I first tried it with just the bottoms section of the 1/2" copper tubes, just full enough so the carbon rods could set on the sand.
Did not work at all for any output. I then tore down the assembly and removed the rods . I felt compelled to have some sort of seperater between the bottom of the carbon rods and the tubing sides. So I installed a small piece of rubber hose over the bottom of the each rod so they could not short out against the copper tube.  I supported the each rod top by hand as i filled the space with the sand, then filled the tubes all the way up to the top of the Cu tubes, minus a 1/2". I left this space open so i could install the Rubber hose so the #22 wire could be attached.
Graphite/Carbon rods = 1/4" diameter manufactured by ArcAir (Carbon arc Gouging Rods)
Solder up = The bottom of the U or each side and the bottom are soldered. The top section is a push fit so i could remove to work with.
Wire connection to C rods = I used a small piece of rubber tubing and pushed this over the diameter of the carbon rod, then i inserted a small diameter probe to expand the rubber so i could insert the AGW # 22 solid copper hook wire. The wire is approx 4 inches long, I did this on both carbon rods.
Output Voltage = 0.226 mV, note: the E is climbing and falling about two points.

I used what i had on hand to see if I could get any responce out of the concept.

Sorry for not following the specific directions.

Bill


Hope this all makes sence ?

Opps
Had a typo It is 293.5 mV not 0.293 mV

Sorry.... darn fingers anyway

Hi Bill, and everyone. Many thanks for your prompt detailed response. The fact that you quote measurements in inches suggests you may be in USA? I am using 15mm[about1/2inch ] copper here. as 12mm is hard to find. I guess we all use what we can find in our first experiments. I share your worries about the graphite shorting to the copper., but note that Thomas Trawoeger specifically warns against anything that restrains the lower ends of the rods. Diagram seems to show whole of tubes full of sand.I  too have a "pull off" upper section for inspection etc. I am hoping to have whole job completed late next week. It is great if we all try slightly different things, but it is important to share ALL results, both positive and negative.This is the only path to success..Wishing you Watts of power, Ken
