The Gabriel Device, possible COP=8

[sergenet]

Was hoping to hear from Mav about helping him out. Chet, maybe you and I (and others if they like to join) can set up a fund which can be used to help out where it is  needed the most. What do you think?

I also have a question...

If I remember correctly, high permeability is of such importance that Mav ordered a custom outer shell to ensure tight fit, but then had troubles fitting/winding the secondary inside of the 'fitted' primary shell.

What about using the loose fitted exhaust donut as he did in his original build, then weld shut the outer shell except leaving a small gap to to fill the core with non-conductive magnetic coil powder (like this here:  http://cgi.ebay.ca/MAGNETITE-500g-Magnetic-non-conductive-COIL-CORE-POWDER-/260773524077?pt=LH_DefaultDomain_3&hash=item3cb750326d ), and then seal it up.

Wiki says the powder can increase permeability by >1000x.  (see: http://en.wikipedia.org/wiki/Magnetic_core )


Thoughts?


Aphasiac.

I believe Mav found that the top and bottom halves need to be insulated from each other or it doesn't work as the original.

I dont currently have a lot to spare but id be willing to chip in a few bucks to help the cause. let me know

I think figuring out how to finance our selfless researchers is imperative!
While I am presently cash poor.It would definitely make my day to be able to help some of these men on a regular basis.

I know that there are reservations amongst some about maintaining anonymity
I have absolutely no problem with this!

Perhaps you can start another thread Serge to bounce around ideas?
this has always been an issue with our community,Case in point "mavs" being strapped for cash ,hindering his efforts.

Not quite sure how, but we need to be able to focus our resources where they will do the most good.

Thanks
Chet

thanks wayne, so outer shell needs to be saturated so coupling to secondary can take place. Low permeability and low saturation for outer shell, high permeability for inner core,....high saturation or low saturation for core? I know ferrite is only 200 to 500 mT compared to iron of 1.6 T...hmmmm would you happen to know the saturation for the M-417.. thanks. Hope I have that right, if not let me know please.

The inner core is not meant to operate in a saturated mode since it's purpose is to capture as much of the secondary coil flux as possible so that it is not reflected back to the primary, thus minimizing the BEMF. This is what gives the OU.

Magnetec info indicates 1.2T for saturation.
