Tesla Switch need help

@Groundloop

Can you post this?

Have you seen this document: http://home.no/ufoufoufoufo/FECAP/cond.zip

I've had no luck at all in downloading it as it times out.

@tak22,

I have tried several times to post this document but get this error message:

" The attachments upload directory is not writable. Your attachment or avatar cannot be saved."

[EDIT] I have tried approx. 20 times now. Both as .zip and as .doc
          The document has drawings and is useless as .txt formet.
           Check your PM, I can mail it to you.

Groundloop.

thanks for the attempt. are you trying to post the cond.zip file? maybe try posting the unzipped document, or if it's just text you could insert it. thanks.

This document describes the method of filling a cap via an inductor coil so that we get a 1.4 Gain.
Is there anybody reading this that can check the math in this document? (I'm poor with math.)

Hi Groundloop,

Well, maybe I am wrong but following the logic introduced first in Pages 3 and 4 and then in Pages 8 and 9 the math seems ok BUT I have not seen anybody reporting he has got a 1.4 Gain in practice. I have not done this personally either.

Now if we look at the attached document, is this (described in the document) what we are doing here?

Well, not exactly because of the different number of switches and capacitors.  In the cond.doc file there is only one real on/off switch and they suggest a diode for the other switch to transfer the charge to C2 ( Page 8, Picture 9, the right side of the toggle switch is not needed and can be substituted by high speed switching diode).

First we charge up two caps (in parallel) via an inductor coil. Then we series those two caps and dump
them into the other two caps (in parallel) via an inductor coil. Any comments on this?

I think this setup you refer to has been simulated and -with small changes was tested by different people and nobody has managed to prove ou by correct measurements. See this link here: http://www.overunity.com/index.php/topic,133.0.html 
or this one is much more interesting: http://www.overunity.com/index.php/topic,1942.0.html  (seeing the different brightnesses of the lamps visually does not neccessarily mean ou...)
and from an earlier thread here: http://www.overunity.com/index.php/topic,204.0.html   

So I think that as a first step the circuit in Picture 9, Page 8 of the cond.doc is to be tested with real components to check for the 1.4 Gain.  Then the second step could be Fausto's 4 cap test 1 (SERIES going to SERIES via a coil) because he says strange behavior in that case. I am sorry for not able to do real hands-on experiments now due to another commitment but will try to be of help here with schematics discussion etc.

@Gyulasun,

Thank you for taking time to read the document. I did look at the links you provided. Very interesting to see that other people had a go at this replication also. According to the math it is possible to charge up a capacitor through a coil and then discharge the same capacitor through a coil again without big loss. I will continue my work to get a (almost) loss less switch for this project. I'm currently learning to do simulations in various programs. Never to late to teach an old dog new tricks. LOL Those advanced simulation programs was not available "in the old days" because the computer did not exist. I will take this in slow steps as said before. First goal for me is getting a good simulation going. Then I can model real life on my first prototype switch. Next goal is to get the battery switch to work. So I'm working on both methods for switching. Third and final goal is using signal transformers instead of opto-couplers.
