The Brnbrade Coil/Overunity?

[scotty1]

Hey Erfinder....or can i use your real name now?
I guess the way you could answer is to tell everyone that you have no models built, or have not tested any of your drawings.
It will be good if you post all you thoughts....then i can post all my work...as i've been doing alot of testing and building....in fact we have 2 models being built.
Maybe you could just tell us what electricity is..what makes it and how it runs in a wire.
As you told me the other day Erfinder.....you will be up there telling them how it is.
So make sure you tell them that a collapsing field in a pulsed coil is NOT due to the sudden disruption...but rather something else...and make sure you explain about what Moray said....When you put something under strain and then let it go..............
And make sure you explain Ed's words on the same thing........roll up the 6 magnets and LET THEM LOOSE....da...da...da.
I have already compiled my notes on these matters.....It will be nice to have something to compare them too.
Now even though you told me that you would try to keep your lecture away from me....I'm quite sure that someone will send it to me....same as they sent me all the posts you deleted....
------------------------------------------------------------------------------------------------------------------------------------
For anybody interested in this line of study...please mail me with any questions and i'll do my best to answer.....but please note...many of my answers invole experimentation.
Experimentation and building models is the only way to advance our studies...unless you are Erfinder who says "you know when you know"     know what?
Some of my info is in my Yahoo group...linked to leedskalnin.com
Funny that Erfinder NEVER made one post there even though he was a member until last week.
And he has had the answers we seek all this time....now that's funny mate.

Sorry to resurrect this old thread, but I was wondering if people are still experimenting with the McFarland patent.

I reread the patent and I realized what it is, and it works.

It's so simple and it creates a lot of tension (or voltage) as he says.

It's even like a battery, just like he says.

But there is a catch to it.    It needs to be STARTED with a battery or magnet.

But it's very simple to start it.  In fact others have done it.  In fact it's used in industry 

Can anybody guess what it is?

My guess would be the coils act like capacitors, the collapsing field produces a inductive discharge current of high voltage --- meaning electrostatic induction?
You have it working then?

Lemme guess..... The scope shots look like a high-back kitchen chair and none of the frequencies calculate to fit in the coil space.

Magnetostrictive oscillator with buck and boost feedback.

Guys, if you read what he says carefully, especially how to start it, and how he "keeps it alive" when not in use, and that it's beneficial to make it long, etc..  you will quickly realize that this thing is a .....    SUPER INDUCTOR.

I did some calculation on the amount of energy you can store in it and it's significant especially if it has lots of length and wire and quite some volume of iron  (area of solenoids x length) and of course high permeability of iron.

The circuit of how to keep it alive is simple and I finally realized what the guy is talking about. 
It is a type of battery, and it does produce high tension with increasing number of turns, but what it's not is a free energy device.

It has to be "started" or the flux has to be built up in it.   And that's where the trick is.   He of course did not say anything about the device running forever, or about the device mysteriously creating energy or any of that.

It's just like a super capacitor or a battery, it's simply an energy storage device and the energy needs to be put into it in the form of magnetic flux.

Here's the energy in an inductor:

U = 1/2 L  i^2 ,  if we replace  L with N^2 u A / length

U = (N i)^2 u A / (2 length),   realize u = u_0 x u_r, where for steel u_r = 8000

Notice N = number of turns is squared, and so it's the current.

Image 1000 turns and 10 amps, that's 10 000 x 10 000 = 100 million
constant u_0 = 4 pi (1e-7)

Do the math and assume some length like he suggests and you will see what kind of energy you can get stored in it.

I calculated something close to my 12 volt battery capacity (the 5 Ah one)

EM

P.S.  Actually assuming 2 meter length , 1000 turns and 10 amps, and 8000 for the relative permeability I get 25 Joules, much lower then a 12 volt 5Ah battery, but not bad, it's a battery to be sure.

He mentions that you don't need the compound helixes, or the two coils on one rod, they can have just one coil, and that also makes lots of sence.  What you do need is the two rods, so the flux path can closed and the flux build up to high levels.   The use of the many iron rods is just to eliminate the eddy currents that he mentions they rob him of the high tension or voltage.  Again perfectly makes sense.  Then the direction of the winding, again makes perfect sense.  (imagine two side by side spiral or coils wound identically and connect them at the ends, then determine the way the flux is created, and you will find the two coils work together, i.e. N to S pole, so yes a closed flux path.
