The Gabriel Device, possible COP=8

[taomaster]

I know of two reasonable options:

(1) Go to an auto muffler shop for a donut, and glue the two halves together.

(2) Instead of getting a toroidal shape for the enclosure, you can make your "surround" out of flat steel. Bend two steel strips into "rings", weld flat "tops" on an end of each one, and glue the two parts together to make a cylinder.

Be sure to check out the detailed spreadsheet in the Yahoo group. It's got a lot of good information there.

OK thank you !!!

Ok, so what's up? Did you finely tune it and are attempting a patent (which the gov and big business wont let ya; but ya can try); or are you still trying to replicate your work? Get it tuned? This thread was hot.

I was playing around with small ferrite ring and iron nail. Some turns in iron nail (lets call this L1), sticked that through ferrite ring that had turns all around so it was toroidal coil (L2). So toroid and iron nail coils were perpendicular. I put 50 Hz AC through iron nail and there was voltage in toroidal coil. Not much because of low number of turns but voltage is voltage.

Next I wound coil in the ferrite ring around it so that this coil (L3) was in same direction as the coil in iron nail and also perpendicular to L2. This coil also showed voltage. When I shorted toroidal coil L2 voltage in L3 did not change and vice versa. Then I put 50 Hz AC going though L3 and now there was voltage in L2 and in L1. Same thing again when shorting L2 and L1, no effect on each other.

Now what is happening in the little ferrite ring ? It gets magnetic field from the primary and flux wants to go in circles. As it does this the flux goes through the secondary windings and generates voltage there. This then creates flux in the reverse direction according to Lenz law. But quess what ? Primary does not care because the flux does not cross it and no back EMF gets to primary.

Well, this is my speculation anyway. So Shubert, would you be willing to do a simple test ? When you have your toroid ready (and waiting for that steel donut to arrive), wound coil around it as just described and use that as primary. Is there any voltage in toroidal coil ?
If there is voltage, can you get any power from it and if so does it affect your source in any way ? Another test could be to put a rod with a coil inside the toroid and see if there comes any voltage.

Now lets assume this works as it did for me (unless I was having measurement trouble). How could you keep the primary running so that it does not need to use that toaster ? I am thinking about capacitor in parallel with the primary coil. If selected so that LC combination would block 50/60 Hz signal then toaster is history. If the secondary then can take load from this magnetic field so that it does not affect LC of primary then there would be close to zero power usage in primary. With perpendicular coils this should be possible. Actually I have seen some pictures in Tesla patents that used perpendicular coils, realised that after I did my adhoc testing round.
Easiest way to make this AC filter work is to use a light bulb after primary coil and capacitor. Change capacitance until light goes dim and there you have your AC filter.

Lets further assume that it is possible to make such filter, then put same kind of filter in the secondary in series (C needs to be different of course, same kind of tuning procedure could be done here). It should boost the output even more, this is well explained in Utkin paper that I have been reading recently.
Just google 'Utkin Tesla' to find it, it contains all you need to know about how to build stuff that deals with back EMF problem and it is well worth reading. It shows many ways how to make energy 'out of thin air'. There are difficult ways and there are easy ways. We just need to select one, for a beginning a transformer anyone can build would be a good starting point.

First, in your setup it looks like the BITT (Frolov Transformer) setup, not the Tesla device/Gabriel device, for more explanation you can read the BITT topic, but I think the Tesla/Gabriel version is far more efficient because you have magnetic diode: Flux primary go to secondary but flux of secondary remain in the inner core, then one way flux transfer...

I have found a steel donut on Ebay but the auction is not ended... So the product is in America and I live in France, so the first test would be in several weeks only... (I hope the donut is cut in half and not soldered together... I don't know how these stuff are sold...)

If your ampere turns is correct, then no saturation of L1 or the inner core, capacitor is not needed only if you want to correct the PF of your trafos...

So I have a power amp, so the ampere turn stuff is not a problem for me.

Economically and industrially, the Tesla device is more profitable to produce since you need two windings instead of three, and the you can use actual winding machine... The one drawback is the high permeability of the inner core price...
