The Gabriel Device, possible COP=8

I posted my last comment cause I saw a core of Import in his picture that looks like a nice size; but it might only have a perm of 125 U or 1000 U or something...The site that I posted has some 15,000 U and some large 10,000 U cores that might help. Does anyone know what U the shell has? I know we want a large difference from the shell and the core right? If anyone knows what the U of Iron wire, Steel Shell please let me know. Also what is the U of the core Mav is using? I thought he said he is using M417 but I can't find it's U, anyone?

The M-417 is 18,000.
Some of the ferrites has 15,000 from the website you posted, which is pretty good.

Thanks Wayne, Well for 15 US dollars I think I might go with a 10000 U ferrite core.

Also, I know this is a little off topic but I have seen some others in this thread that are using Iron wire as the outter shell. I was just thinking if you did a insulated bifilar iron winding around core and the secondary; then put the primary on top of it so it would be used as the shell. If I send DC current thru the Bifilar iron wire shell in opposite directions to cancel their fields could that help breakup the coupling from the primary and the secondary. But the iron wire could still be the shell.. I just thought if I send the DC current in with a pot resistor I could maybe tune the shell to only allow so much coupling? Just a thought, will try when I get some friggin money. Peace.

PS. it might be a good Ideal to put in a diode for each of the iron wire so any bemf doesn't fry your DC powersupply. Cheers.

I dug all over that site  (  http://www.cwsbytemark.com/index.php?main_page=index&cPath=206_221&sortby=data2&sortorder=a&page=1&sort=field&sortby=data2&sortorder=d )
and could not find any cores of any size more than around 200 u.  Is this the site you are referring to?  Could you post a link of any of the 10000 or 15000 u cores?  Thanks !

I have another question, how does saturation effect this process? Or how do you think it does. I see alot about Permeability but not about saturation. I was looking up

Permeability of Iron, http://info.ee.surrey.ac.uk/Workshop/advice/coils/mu/#class

about mid way down.

And steel, http://en.wikipedia.org/wiki/Permeability_%28electromagnetism%29

I can see kind of how it works but then I see this about Saturation of Iron compared to Ferrite, Iron being 1.6 T and Ferrite being 200mt to 500 mT.

Can anyone clear this up as how it would apply to the Gabriel Device?
