Captret - Capacitor and Electret

[romerouk]

Hi!
This is not about captret... but if you can help me...
I try to replicate this Dr. Stiffler's experiment. -- see the diagram and table with his results.
I have electrolytic capacitor 100uF/100V and Avramenko plug with 4 diodes 1N4148.
My result after 40 hours is that a capacitor is charging but very slowly...

time:
0 hours -- cap: 0.343 V
6 hours -- cap: 0.388 V
16 hours -- cap: 0.436 V
40 hours -- cap: 0.522 V

Can anybody explain me why my capacitor is not charging same speed as Dr. Stiffler's capacitor?
Do I need more diodes in series? Why is more diodes better?
Thanks

Make sure that no light goes to the diodes (cover them with something) then start measurements again.

All the best,

Hello michael,

I think it has to do with the ground-connection which is different in each house. The neutral-line is connected with the ground-line ( in german-speaking europe we call it mass-line ) behind the main fuse-box of your house. So this physical point must be very well connected otherwise an ac-component which is induced  by the hot-line in the neutral line builds up. This is so because the hot- and the neutral line run parallell very close together. This ac-component is called loop-current and should be as low as possible. If the connecting point is in bad shape it has a higher ac-resistance any induced ac-current in the neutral-line cannot flow down to the ground via the groundline. This loop current oscillates between neutral- and ground-line from the connecting-point upwards to your wall-socket and I think that this is the current which charges your cap via the Avramenko-Plug.
So there is nothing you can do about it as it seems that your connecting-point is in better shape than the one from Stiffler´s house.

How to measure the loop-current ? Take a digi-meter switch to AC-mode and measure between ground-plug and neutral-line-plug. What does it read ? Millivolts or even volts ?

@RomeroUK: Thank you. There is no change with the diodes covered. (Does a diode work different under light? I don't know this... ()

@Kator01: Thank you! Between the ground and neutral line is 72 mV. Is it low?

And I still don't understand what is a difference between the Avramenko plug with just two diodes and AV-plug with more than two diodes?! (Stiffler has 18 diodes as AV-plug in some diagrams. - Why?)

@ All

I just posted a circuit that needs 1.5 VDC to power it at http://www.overunity.com/index.php?topic=6763.msg263776#msg263776

I wonder if this circuit could be used in charging up a super or ultra capacitor in order to run the above mentioned circuit.

If anyone has access to a  super or ultra capacitor and is able to see if it can be charged by the captret circuit it could be a way forward to OU for us all.

Any and all feedback from everyone is welcome.

Pal

most semiconductors are light sensitive and photovoltaic.
if the diode cases leaks light it can act as a solar cell.
