Graham Gunderson's Energy conference presentation Most impressive and mysterious

[ramset]

In a perfect World a man Like Graham would have unlimited resources and equipment
he would not have to work with repurposed pieces.

so methods or "bench smarts" he utilizes to achieve his result should not be considered
"quackery"

But more so considered a very good understanding of the media he works in and just how skilled he truly is
Turning a Ukulele into a Stradivarius on a shoestring budget should be commended not ridiculed .

we are most fortunate to have him sharing.

Well, the laws of physics don't get "waived" just because you are all excited.

Look at the attached pictures.  The main magnetic circuit is an inverted "u" with
the primary on the high-permeability horizontal core piece and the two secondaries on
the two vertical low-permeability core pieces.  There is no closed loop in that magnetic
circuit but presumably the three separate core pieces are nicely magnetically coupled with
nice flat surfaces flush to each other.  There is presumably enough magnetic energy
storage capacity in the three core pieces to effectively couple the primary to the
two secondaries.

Then all of the ceramic biasing magnets are arguably nothing more than window dressing
imposing some kind of DC magnetic bias on the main inverted "u" magnetic circuit.  As
we all know from basic electronics, any kind of DC magnetic bias will have no affect
whatsoever on the three coils which only react to AC changes in magnetic flux.

Will all of these DC biasing magnets affect the resonant frequency of the LC tank circuit?
(I think it is between external capacitors and the primary coil.)  The answer to that is
most likely yes, it will have an impact on the resonant frequency.

So, what would happen if you removed all of the "window dressing" DC biasing magnets?
Presumably the resonant frequency would change.  Therefore, you would need to change
the frequency that the electronics circuitry was running at to match the new resonant
frequency.  Alternatively, you could keep the same operating frequency for the electronics
circuitry and simply adjust the capacitance in the LC tank circuit so the two frequencies
line up.

In simple terms:  The expectation is that a new setup with all of the DC biasing magnets
removed would be functionally equivalent to the current setup with all of the DC biasing
magnets in place.  The laws of physics are not going to change in this setup as compared
to any other setup.

Well, the laws of physics don't get "waived" just because you are all excited.

When it comes to Electrical Engineering, many of these laws operate non-linearly or in one-way interactions.

As we crack this nut, in the end, the solution will probably end up looking similar to the solution found to the 'heavier-than-air flight' problem.

What was needed for heavier-than-air flight?   Strong forward thrust on a lightweight craft with a large wing surface area, and adequate control surfaces to manage the entire system.   (Strong impulses on an efficient transformer with variable permeability, and  precise control circuitry to manage the entire system...  hah, just a though)

If we're talking about a static, non-parametric system, I certainly agree with you, that 'heavier-than-air flight is impossible' .

Look at the attached pictures.

  Sorry, that flux direction note of mine was incorrect (as Spokane1 pointed out a couple days ago).  I incorrectly assumed the dots represented polarities, but in reality the magnets are in a closed loop (N-S) with the high perm ferrite in the center.  I guess that throws off the rest of your analysis above.


  The interaction in this setup is obviously complicated, and requires some extensive math to properly model.   You're dealing with a flux loop and multiple permeabilities with abruptly interrupted loads.  Each of those can have non-linear interactions, that might be combined in ways to allow a more complicated process to transpire.  Consider other non-linear and parametric systems and how they interact, and the entire process starts to make more sense.

Dear Builders,

For those of you getting materials to join this technical hay ride here are some reference measurements that might be handy:

The top and bottom support plates are 1" thick (I know they look thicker in the photos)

The smaller of the plastic threaded rods (8X total) are 1/4" diameter and made of 6/6 Nylon. I don't know the size of the two larger rods. I'm going to order 3/8" rod.

Graham use G-10 for his primary coil form. He recommends using Polycarbonate instead. He made a jig composed of two large hardware "L" brackets to wind the primary.

The main core has a bottom dimension of 100mm it looks like 4" to me with 1" arms

Don't attempt to find exact replacements for those PM's. The orange paint is to tell Graham that these are Barium Ferrite magnets. We will have to do the best we can with mortal magnets
about the same size. I'm starting with some small Class 8 units from Applied Magnets for $0.023 each. If you can get the same size you will need at lease 72 of them and probably more to
make up the difference in strength.

McMaster-Carr has all the nylon rod, nuts, washers, and 1/16" polycarbonate sheet you will need

Graham has a small vertical CNC mill that he used to cut all the acrylic and the small magnetic spacers.

That's news to me.  Which laws are you talking about?  Certainly magnetic systems like transformers are inherently non-linear in their behaviour, but that is a given and it has always been that way.

  Suppose you could charge an inductor with 10a of current while it is 10uH, and then discharge it when it is 1H.  Or for dielectricity, imagine charging a capacitor to 5v while it is 1uF and discharging it when it is 1F.  Graham's setups may very well work on different principles, but this was the type of parametric variation I was referring to.

I thought that the nut was already cracked last year.  This information has been available since 2015.  However, it has been one full year since the release of this information and I am not aware of any successful replications, are you?

  Replication of anything is exceedingly difficult until you begin to understand the principles behind it.  Damascus steel from millenia past was found to be covered with carbon nanotubes that gave it an increased strength.  It wasn't until post-2000's that we discovered the details and principles behind it .

  Following that concept, I think that exploring the unique switching mechanisms he uses will help us gain a better understanding of the operating principles rather than blindly trying to replicate.


  I do appreciate you playing devil's advocate and ensuring we maintain scientific principles, and if you have a direction you think we should be headed, please let us know.  Lets just try not to veer too far off topic.  If you think it's a fraud, say so.
