PhysicsProf Steven E. Jones circuit shows 8x overunity ?

  Here's one I've puzzled over for awhile.  Now I share with you...

  Consider a toroid, that is a solenoid bent in the shape of a doughnut, wound tightly with wire.
Textbooks point out that with a DC current, the magnetic field B outside the toroid is ZERO.  For example, one can do a vector sum of B fields from individual wires, and these add to zero.  Or use Ampere's law to get the same result.

  Now apply an alternating current of high frequency to the wound-toroid.   Is the B field outside the toroid everywhere zero?  I think the answer is still yes (by Ampere's law).

  Next, add a loop of wire threaded through the center of the toroid and then circling around it, and put in a light bulb to form a complete loop (loop perpendicular to the plane of the toroid).  The light bulb lights up showing (AC) current in this external loop. 

  Yet all along the wire loop, the B field is zero.  So how do the electrons in the external loop "know" that there is a changing flux down INSIDE the toroid?

Hey Steven

With a toroid transformer, all the action is in the doughnut hole.    You need only have the wire pass through the hole and you will get the same output without looping around any of the outer sides. Without looping around tightly anyways, as if you connect a load to the wire, there will be a loop.

In the Utkin pdf, it shows a wound toroid, just wound on 2 parts of the core, say far left and far right, then wind around the outside of the toroid where your outside winding covers the first 2 windings but not through the hole. Supposedly this allows the outer winding(primary) to induce the inner windings(secondary) without the inner windings affecting the outer winding. Meant for pulsed mode I believe.

This PDF explains it quite clearly as to how the fields propagate through a toroid core and coils. I believe it is correct.    Its only 18 pages.  Read carefully, and you will get the picture.

I found that PDF intriguing, Mags.   He points out logical errors in the notion that all the field in a wire-wound toroid (with high-permeability core) is contained inside the toroid when AC is applied.  I think many textbooks give this (misleading) impression of containment of the B field inside the toroid...
Very interesting indeed.

Has this guy looked into "new energy" possibilities?  (apparently not, but would be interested if he has.  I like the way he shows things.)

Hey Steve

I got this pdf last year that came to me with another that supposedly one needs to read the first in order to compliment the other. The second one is below.

Im glad you took a good look at it. I have some linear hall sensors coming in this week hopefully, and Ill put them to good use in this and other areas.

Like you said about text books misleading, why would that be?  Is there a 'good' reason not to show how the fields interact with the windings?  If it is the E-field that causes mutual induction and not the magnetic field, then how does a moving magnet induce current in a wire??  Some will say oh, that is different but no clear explanation of what and why. The problem I have with that is, I can replace a magnet with a coil in a generator and I can get the same output from the pickup coil.  Is that to say that the magnet has an e-field?    

Anyways, Im glad you took the time to really get a grip on the pdfs ideas, and say that it makes sense.

As for the next pdf, I have put together a 5 core setup, that I had some good results from what I could see, but only recently have the tools to be sure. I have a lot of things set aside because of lack of tools to go further with better data.

  A significant paper on fusion was published today in Nature:

http://www.nature.com/nphys/journal/v3/n10/abs/nphys742.html

Particularly important to me because Prof. Johann Rafelski (Univ of Arizona) is a good friend, and is one of the co-authors of the paper.

A decent write-up is given here:
http://www.livescience.com/40246-new-boron-method-nuclear-fusion.html

Quoting from the article:

"Here we propose and implement a means to drive fusion reactions between protons and boron-11 nuclei, by colliding a laser-accelerated proton beam with a laser-generated boron plasma. We report proton-boron reaction rates that are orders of magnitude higher than those reported previously. Beyond fusion, our approach demonstrates a new means for exploring low-energy nuclear reactions..."

Note particularly the reference to "a new means for exploring low-energy nuclear reactions".
That's what we call LENR.

Exciting stuff.
