Digest and understand as much of what I have written as you can .. check it out any which way you like. .. I have explained each step as an engineering progression So you can understand why and how and then adapt to what materials you have.

I wish you all a Happy, and I hope very different new year ! Bless Duncan.

We're still here

Duncan,
Neither Matt nor I have given up, nor have we sold out to the powers that be. Matt is busy right now with his farm, and I have been concentrating on this generator project. If and when we have something that is PROVEN to work, we will probably dump it here. I have had a major company providing me with parts and things that I have needed, but haven't had to sign away anything to get that contribution. I suppose they could eventually try and steal away the design and patent it, but I have made no promises not to disclose. So we're still around and working on things.

I posted (just today) on the 3BGS thread EXACTLY where I truly believe we need to concentrate our research efforts. Haven't read your pdf yet, but looking forward to it.

I have been sharing anything I come up with in emails to a whole group of folks, but so far nothing to write home to mom about. If I discover something incredible, a whole mess of folks will know about it. Never fear.

Duncan,
You may not know just how committed to the investigation of this stuff I really am. So I will make you this offer. You know my email address. If you want to walk me step by step through the construction of the device you believe will work, I will happily incur the expense of purchasing the specific parts if you will point them out to me. I would follow your directions for the build and post pictures and results here so that everyone can see. I believe I have most of the meters and measuring equipment I would need to complete such a project. As I see it, the first step would be the magnetic material for a torrid? If so, do you have any idea where to obtain such? If not, what IS the first step. I say let's get cracking. Time's a wasting.

Core material

Would the iron core from an old transformer be suitable for an attempted build? I would think so. Would it be okay to chop the transformer core with a bandsaw? I tried to use a hacksaw on a transformer one time and that stuff is hard to saw. I also have some small ferrite beads and odd pieces. Do they need to fit tightly? Do you have any thoughts on that?

'What one fool can do, another can (ancient simian proverb) quoted by Silvanus P Thomson a FE resercher of note hmself


Silvanus P Thompson'Soft magnetic material' this is what our four separate cores are made of . Soft magnetic material .
The other end of the magnet is Holding paper clips , They are not made of Iron they are made of mild steel MS It is a very different kettle of fish ! if you carefully remove the magnet all the paper clips will remain stuck together, they will remain magnetised because Mild steel is a very hard magnetic material . Exactly what we do not dΦ
..............dt

.. where T is the number of turns
dΦ is the changing magnetic flux
dt is the time it changes in

For those who hate to tangle with calculus in any shape or form

E = Turns x (Φ1-Φ2EMF Equation of Transformer | Turns Voltage Transformation Ratio of Transformer | Electrical Engineering
So now do you grasp how simple it really is ? There is no need to get complex .. there is nothing complex or complicated happening here or else I couldn't possibly under stand it I assure you.
Now perhaps you also see why Steve Mark was so busily engaged in working out turns ratio's It is essentially a transformer action.. although much faster than you would normally be used to . Which is why as I say I am struggling to find suitable core material. I hope that clears things a little bit for you all. and lets you see whats required and why ! PS Steve Mark tells us his frequency was 8KHz .. I see no reason to doubt that Its the center of a loud speakers spectrum (ish) Its material he would have mmmm whats the word I'm liiking for

Hi Duncan,

Just wondering if a ferrite material would work for the core?

Hi Duncan,

Hi Netica It probably would ... depending there are various grades and types of ferrite. I did buy some ex USSR ones to try about 5 inch Dia .. Its difficult stuff to cut very nicley as you probably know but an electric Tile cutter managed a fair job (eventually) I tried the cores with a signal injector and a few windings into a scope to see the transfer .. pretty worthless, which of course doesn't mean all ferrite cores are worthless .. again its down to magnetic engineering and I dont even see to much avaliable for even freq responce curves on the WWW .. obviously the stuff does exsist every loudspeaker uses the principle some up to a 1000watt s

Hi Duncan,

Might be to expensive to find something to use in ferrite then. But I could imagine that it would be quite feasible with some money and engineering.

I don't know much about the material construction within a speaker other that what I have seen when pulling one apart, and to me it just looked like a coiled wire floating within a permanent magnets magnetic field attached to the speaker.

Soft mild steel as you are trying out, might be one of the easiest cheap materials to use. I have found that it is important to use steel with the least amount of carbon content that can be found for switching magnetic fields on and off and not retaining magnetism.

I have also experimented with Leedskalnin's perpetual magnet holder and found it only works with carbon in the steel, take the carbon away and it doesn't work.

I am going to try pure Iron I have bought some from these guys but I don't have the means to bend it , Its at a black smiths .. far from Ideal but its got to be worth a try

Legg Brothers - Specialist Hot Rollers of Small Steel Sections - Wolverhampton West Midlands

don't know how long he's going to take to bend the stuff but I'll report in due course if some one doesn't beat me to it . Its a big ask isn't it for something to reverse polarity 8ooo times a second very efficently but of course that's exactly what a loudspeaker must do there's no question about that !! it also must transduce wow those things at Rock gigs .. 1000s of watts efficiently and be a very soft magnetic material ... give me a name and a source for that stuff my kingdom for a bit of magnetic stuff

Duncan, thanks for all your sharing, and helping beat back the fog of scientific amnesia into which I and many others been schooled.

It seems to me you're saying a few things:
- series resonance involves a 90 degree phase shift between voltage and magnetism/current.
- series resonance (thru a 90 deg phase shift) is one pathway to negative resistance, or drawing energy into a circuit from the electrostatic ambient/vacuum. In this sense, it is not strictly overunity (for the sticklers), but rather, a circuit's means to extracting additional energy from the environment.

There seem to be a number of different ways to skin this series resonance cat (e.g., via placement of capacitor, parallel bifi coil windings, caduceus windings, 555 timer switch before inductor...). Many are approaching it from different directions, like hunters moving through the forest along different paths to warm themselves at the same fire. Surely we're moving toward a common understanding this way.

Happy New Year!
Bob

Q series resonance involves a 90 degree phase shift between voltage and magnetism/current.
A. series and parallel resonance are caused by a 90 deg phase shift between voltage and current but the order is reversed
Q series resonance (thru a 90 deg phase shift) is one pathway to negative resistance, or drawing energy into a circuit from the electrostatic ambient/vacuum. In this sense, it is not strictly overunity (for the sticklers), but rather, a circuit's means to extracting additional energy from the environment.
A series resonance is the only pathway to COP>1 in these electrical machines. every single one of them. series resonance is in the picture some where. thats why its hidden
Bob let me put it in clear --- there are two forces in electricity 1/electrostatic and 2/ electromagnetic
Electric forces
Magnetic forces
also on the same page Bob you'll see the Lorentz/Eienstein force law which is where all the corruptin originates if you look at the magnetic section you'll see a 90 deg vector this would be used for what you commonly call radio waves

now look at the electrostatic offering .. its just missing , so's all the maths technology and information ... as a radio wave is tuned into a feeble voltage at resonance
so at linear resonance the electrostatic wave Teslas wireless wave .. which you may know as the sea of energy is turned to massive ammounts of magnetic current .. which you may know as reactive current. He's a few things to consider Bob .. A lead acid battery will charge just as well on reactive current as it will on real current. Its a huge exception to the rule ! Read through this if you doubt that.

Capacitive Battery Charger - John Saves Energy

That resonant state is difficult to hold and changes with load and battery condition .. as you know from the 3BGS .. because that's what's happening .. the series resonant impulse wave is making the battery resonant to the electrostatic wave , which allows huge amounts of magnetic current to flow ... IMHO the motors and bad batteries are just a means to develop a sharp impulse wave.
And what you call 'in the zone' is being lucky to find series resonance and stay on it for a while
