Hello Mike. I really am joking. No offense intended. In fact I was just so amused at your engineer's need to patent. Way too much time and money and very little protection notwithstanding. But we both know that.

In any event - it is exactly the same principle as you've been testing. I'm very aware of it. But it's also a simple solution - if it works. Of all the contributors here I've a shrewd idea you'd do it best justice. In any event - neat if it works. I suspect it needs those wide - less inductive resistive elements that Fuzzy's making - but if there are collapsing fields then some gain may be measurable.

The other has a negativly biased diode with the cathode against the far side of the second resistor - so that current flow from source is moved to one or other resistor during each half of each complete sine wave.

The thinking is this. During the delivery of the above ground current flow the 'stored' field is across the first resistor - and then it's interrupted - and the current is then directed to the second resistor together with the collapsing fields from the first. Repeat in the second cycle - and all within the frequency determined by the supply.


The circuit then returns current to the plug.

Not sure if anyone wants to check this - but it would be an interesting test. And if you use two bar heaters - may be relatively easy to test as well. Just a thought. If it works - Mike - you may not patent it. It's already here - on public record. LOL
do you mean like this

Hello Mike. The schematic is not quite right. The lead is first to a junction with the two resistors in parallel. Then a second junction at the far side of the parallelled resistors back to the plug. Not sure if it makes a difference but the two diodes would then be within those two junctions.

sorry I can't draw these. Hope that helps.

Guys, this is copied over from OU.com. It at least shows where we are and where we're trying to go.

"Grumpy - golly. If I needed ego strokes I certainly would not be posting on this thread. I'd need to stay in friendly territory - or better still, entirely out of the debate.

The quest, if there is one, is to explore some means to access the abundant energy fields that are identified in dark energy. Without any over statement - the fact is that this access is critical for our survival as a species. If we've proved anything it's the simple truth that we continue to guzzle our dwindling energy resources with little if any thought for tomorrow. We've got solar, nuclear and wind energy to exploit - but not even these applications are being progressed at pace. And with burgeoning population numbers and clamorous requirements to adopt 1st World comfort levels the global pollution levels loom large and ever larger. This is now beginning to upturn the fine balance that nature herself seems to require to give us some semblance of a stable environment. So we're flirting with disaster on a scale that is possibly unprecedented since our emergence as a species on this planet.

As I see it - this quest for abundant energy is compulsively attempted by those who spend huge chapters of their lives on both forums and threads such as this. It's still a fringe interest but it's growing. But the dominant theme here is 'free energy' or 'over unity' - with good reason. Because if this can be found and then repeatedly and reliably accessed - then. 'in one fell swoop' we'd have resolved both the quantity available to us and the quality, so to speak. It would be both abundant and clean. And, that we're looking for it at all - is a really good thing. Mainstream have discounted that this can ever be accessed. The best they offer is 'small effects' - essentially unable to reach the megawatt levels that you correctly state is required.

Our hope is to address mainstream with some means to access this energy. Essentially the model proposes that this energy - evident in the vacuum - and now widely acknowledged by most thinking scientists - is also responsible for the 'bound' conditions of amalgams. It's the glue that holds matter together. And the proposal is that - given an imbalanced magnetic field - or potential difference - or measurable voltage - then what is being measured are these fields. And the thesis goes - if there is a measurable voltage then, potentially, there is also a real energy potential that can be harnessed and used. This is what we hope can be proved in this experiment. In other words in as much as inductive components can also show a measured voltage - then they too are potentially able to generate energy in the same way that batteries and utility supplies can generate energy.

But the actual challenge is far greater than this. The model is hardly likely to shake the foundations of physics. It's way too modest and way too simple. And if this test proves it - it is hardly likely to be accepted by our mainstream scientists. But it has one advantage that most other contributors lack. It is an energy that can be measured using classical tools. And it is repeatably evident. It seems to require an aperiodic frequency coupled to a distinctive harmonic - but, generate the right frequency with the right level of inductance - and, indeed, the return far exceeds the level of efficiency that mainstream consider possible. And precisely because we're not talking about COP>2 but some value that is far greater than this, then we are also producing unequivocal evidence.

Our modest hope is to at least bring this to the table at our academies. That way the hope is that we'll find the interest that, thus far, has been wanting. If we get it there it will be a first. Mainstream have never been obliged to consider these interests of ours precisely because we have never seriously brought any reliable evidence to their attention. It's been attempted - but has failed. Our efforts to convince them may be misguided. Indeed our conclusions and even our evidence may be wrong - but we see this as a critical first step to getting the interest that is required to research the effect and harness it's use through applications that I'm reasonably certain need to be more fully explored.

So Grumpy. We're on the same side ... I think? We're just approaching it from a different angle. And believe me, there are no ego strokes in this. It's been bruising on the emotional and intellectual levels and continues to be such. And it's no good saying that if the energy is there - just use it. It's benefit will be evident. Possibly. But to generate any production of any components on any meaningful level - also requires investment funds for research and development. This will be withheld until such time as mainstream say 'OK - there may be some evident benefit'. Then we can sell products without being accused of wilfully defrauding or misleading the public. And what is still a somewhat eccentric science will then, hopefully, become respectable. We need mainstream just so much more than they need us. The challenge is to convince them that the experiment is repeatable and that its results are dependable. ..."

"In any event Grumpy. I hope this answers your concerns. We're not looking for Nobel prizes or even for riches. All we're trying to do here is bring the argument to mainstream. They'll no doubt then find the answer and claim the credit. But that's fine. Just let's address the evidence somehow. That's got to be an improvement on where we are at present. "

Hi everyone,

I just received my replacement 0.25 ohm "shunt" resistor Caddock High Performance Film Resistors it's a "non-inductive" 30 watt type MP930-0.25-1% , I am in the process of removing the wire wound type "Dale" RS-2B .25 ohm 3 watt 3 % that was use on all testing numbers 1 through 8 .

Designing With Caddock MP Series
TO-Style Heat Sink Mountable Power Film Resistors


As soon as it's installed I will start testing later today to publish the Images and Data Sheets for comparison purposes between the two shunt resistors that has been used in my extensive circuit testing and evaluation.

Very nice to see this Fuzzy. Nice harmonics. Looks really promising.

Well done and thank you - yet again - for all this hard work. What star.

Glen, I'm dumbfounded - I really thought that inductive resistor would have had a more dramatic effect on the CSR trace. That's the last time I go against my intuition and listen to Poynt. Sorry for putting you through all this.

So, we still have to find an answer to why that negative transition occurs in that point in time.

And, thank you for triple verifying that we have absolutely no ground loop problems. That drain pulse has got to be one of the cleanest inductive collapse waveforms I have ever seen in my life.

I'll see what I can do to get all the math surrounding the lead inductance figured out.

GREAT JOB!

Harvey and Glen and anyone who may be interested. I've been guilty of never really studying waveforms on our own tests. Nor did I make accurate record because, frankly, I did not see the need for this. Retrospectively I see that this was a gross oversight.

Nor can I explain the polarity difference of the voltage across the Load Resistor and the source shunt - which seems to be intriguingly anomalous. However, I have now gone through my early dissertations on an interpretation of a the model as it relates to current flow. What I repeatedly referenced was a 'shadow' cycle - the point being that this is only allowed at the point at which current flow from a source is interrupted. In my mind's eye I saw this as a flow of current enabled in the opposite direction of the input flow. Subject to the availability of a closed circuit - this would then move in an opposite direction to the original applied potential difference. Hence the requirements of the MOSFET's body diode.

The point is this. It is possible that the collapsing fields in the inductor induce this second shadow cycle - and that this eludes detection on our intruments precisely because it moves through the centre of load resistor and either through the air or through the centre of the connecting wire to impress the negative cycle on the far side of the supply source - in our case, being the batteries. That way the current itself may then be hidden from detection with the probes on the exterior of the components as is required by conventional measurement.

This means, effectively that the energy on the load resistor may be delivered to the battery, as seems evident from the voltage readings across the batteries, and then through the batteries - as seems evident from the voltage polarity across the source shunt. But how the two currents manage the same path? That needs to be explained. Any suggestions would be of some considerable interest here.

Also apparent, and as we've referenced and, indeed, will need to be stressed in the paper, is the fact that the waveform is not easily accessed. It seems, somehow that it needs to be teased out of the circuit and that it relates to the circuit finding it's own 'self regulated' oscillation or resonance condition. This, in a strange way, is a both a comfort and a concern. It's a finely tuned moment and requires some skill at tuning it in. But - given the right learning here, then that moment can be found. Again. What a tribute to Fuzzy that he has done this - I'm sure, and this fact, greatly enabled by his fortunate replication of the required inductance. And that, in turn, may be related to the width of the resistor. But I'm entirely satisfied that the trick here is to let the components find that moment. It is not easily imposed - based as it is on the subtle variations in each circuit board. What does seem to follow, as day follows night, is that the benefits are always evident subject to the evidence of that haromonic. And more to the point. No wonder this has eluded dectection for so long. How many experimentalists have ever deliberately enabled this self-resonating frequency? And why should they have troubled themselves to look for it?

So - to continue with the question - I'm now proposing this. The potential difference transferred from the drain spike is returned to the material of the battery - where the energy/current/zipons originated. It adds to the potential difference of the battery. Surplus energy/current/zipons that emanated from the load resistor are passed through the battery onto the source shunt and returned to its source - again being that load resistor.

In effect positive current flow does not have a closed circuit path and is therefore blocked. Negative current flow does have a closed circuit and is therefore not blocked. And the only explanation I can find for the lack of evidence of that simultaneous negative flow between the load resistor and the drain - is that it is somehow 'hidden' in the material through which it passes - or through the air. We know that both Aaron and Fuzzy had gross RF evidence. Both had lights turning off and on and Fuzzy even had intereference on his TV.

Perhaps this hidden event is really in line with that proposed 'shadow cycle'?

Keep em coming guys thanks for all the new info, progress is addictive?

Okay still ironing out bugs, just adding this here to let you know we are still in the shop . Thanks for being patient and helpful for all's PDF guys, i sincerley appreciate it.

Ash

Hey Glen / all,

I have followed Glen's advice on removing the back spike recovery diode / capacitor / discharge resistor, and tuning the gate resistance for the maximum voltage on the 24v battery. The board used was set for 2.4KHz 3.7%. Nothing exciting to write back about, but here is a log of the test:

* battery no load: 25.65v
* 38mA load, run for 1 minute with ferrite rods: 25.5v
* 28mA load, run for 5 minutes with ferrite rods: 25.45v
* Experimented with adjusting 10 ohm variable resistor - no improved results. * Calibated back to 5.5 ohms.
* Re start timer.
* 28mA load, with ferrite rods: 25.5v
* 28mA load, run for 1 minute with ferrite rods: 25.46v
* 28mA load, run for 3 minutes with ferrite rods: 25.45
* checked a few times between the 3 minute mark up until 40 minutes run - the battery stabilized at 25.45v
* I removed the ferrite rods from inside the resistor, the current draw went up, the battery voltage went down. I quickly re inserted the ferrite rods and the battery voltage stabilized at 25.45v
* There was no noticeable heat on the inductive resistor

Looking at the Quantum October 2002 article, I see they have a 100 ohm variable resistor on the mosfet gate, and that they get frequency oscillations between 143KHz and 200KHz @ 1.3% on a 2.4KHz 3.7% 555 timer board.
These oscillations must be the same wild oscillations I experienced previously. The quantum article states that the 10 ohm wirewound resistor also got fairly warm using 2.4KHz, 3.7%, and the high frequency mosfet oscillations.

What do you suggest?

Andrew

Hi Ash and Andrew,

You guys are working so hard and somehow not getting that optimised number? I think I need to leave this to Fuzzy to try and explain. But if you read my previous posts - you'll see that the trick is to allow the apparatus to find its own preferred oscillation. If it gets chaotic - that's a really good thing. It's usually when the resonance is trying to stabilise and can't.

sorry to read of the struggles. Hopefully Fuzzy can give some advise here.

Thanx Glen,

A much needed test to locate the deviation of the Ch1 mean. And the harmonic sweep is very obvious in these as well.

I have the corrections of the test configurations documented for tests 1-7 and for 8 and beyond. Hopefully I can get that posted up sometime this week after I finish on the inductive reactance analysis and get it presentable. I also intend to implement a cross check against your estimated resistor inductance and test data to compare to measured instantaneous current. You may recall also that I mentioned the ring form on the Ch1 data regarding the slope decay of each successive wave - I knew I had seen it before; Hewlett Packard published a chart of Laplace Transforms and that matches number 4 in their chart for the time function: f(t) =0,t<0,e^-αt(sin βt, t>0. So it is a familiar progression decay of standard ringing with no special characteristics and easily duplicated mathematically. The timing of the negative I still have not figured out and that little spike off in the middle of nowhere with no explainable cause also has me puzzled as well. There must be an event occurring that we are not monitoring...a high to low transition through a capacitor to ground somewhere, I just haven't checked it out well yet.

I don't anticipate any issues with any of the inductive wiring although the 80MHz on that 6" piece between the CSR and the grounding star would normally raise my eyebrows a bit. The fact is, those signals have such a low amplitude, and they are ringing above and below the mean value such that they entirely cancel so the real frequency is well down in the kHz where it just becomes moot. What is even more intriguing is the timing of that impulse. If we use the slope of the load resistor collapse as our determining frequency component for the inductive reactance calculations and apply that to the CSR leads, then we are admitting that negative current is flowing through a closed MOSFET the wrong way when the other side of that MOSFET is at 600V against its flow - can it really be? That body diode is surely reverse biased to the max at that instant. How is that current flowing? Source to gate leakage?; I wouldn't think there is a potential there either. The Spatial test you did ruled out any 'boot strap' effect that I thought maybe happening. So I find myself entertaining some sort of capacitive push occurring in time 90 before the event even occurs. This would be the 100V bump capacitively pushing through the battery, out the B(-) and through the shunt before the body diode has a chance to open and would be likened to charging up the source pin from the back side in anticipation of the expected negative spike on the drain that never occurs. That drain spike drops just as fast as it builds and that 600 volts is being spent somewhere. Since it is not going through the MOSFET it must be moving through the load resistor back to the B(+) terminal. This produces a ringing at the B(+) which can be seen in the scope shots. So all of that energy is either spent in the resistor or put back into the battery. The puzzling thing is that it seems to be just fine without a closed circuit and our CSR just isn't monitoring the current flow from the drain to the B(+) with the MOSFET closed and the drain always above zero so as to prevent the body diode from conducting.

So what other possibilities are there? Quantum Tunneling, Negative Resistance, Electromagnetic return path, Bidirectional Vortex currents, what else?

Even if we were upside down on our current by 2W we still would have to account for 200% more heat than it should be doing.

Hey Glen / all,

I have followed Glen's advice on removing the back spike recovery diode / capacitor / discharge resistor, and tuning the gate resistance for the maximum voltage on the 24v battery. The board used was set for 2.4KHz 3.7%. Nothing exciting to write back about, but here is a log of the test:

* battery no load: 25.65v
* 38mA load, run for 1 minute with ferrite rods: 25.5v
* 28mA load, run for 5 minutes with ferrite rods: 25.45v
* Experimented with adjusting 10 ohm variable resistor - no improved results. * Calibated back to 5.5 ohms.
* Re start timer.
* 28mA load, with ferrite rods: 25.5v
* 28mA load, run for 1 minute with ferrite rods: 25.46v
* 28mA load, run for 3 minutes with ferrite rods: 25.45
* checked a few times between the 3 minute mark up until 40 minutes run - the battery stabilized at 25.45v
* I removed the ferrite rods from inside the resistor, the current draw went up, the battery voltage went down. I quickly re inserted the ferrite rods and the battery voltage stabilized at 25.45v
* There was no noticeable heat on the inductive resistor

Looking at the Quantum October 2002 article, I see they have a 100 ohm variable resistor on the mosfet gate, and that they get frequency oscillations between 143KHz and 200KHz @ 1.3% on a 2.4KHz 3.7% 555 timer board.
These oscillations must be the same wild oscillations I experienced previously. The quantum article states that the 10 ohm wirewound resistor also got fairly warm using 2.4KHz, 3.7%, and the high frequency mosfet oscillations.

What do you suggest?

Andrew
Hi Ash and Andrew,

Thanks again for your testing and evaluation of the RA COP>17 Heater Circuit .....

I am curious about the results you are having possibly could be because of the prototype "Quamtum" load resistor you have constructed ..... I was able to find your Images you posted earlier in the thread POST #2989

Imageshack - glensresistorreplicatioy
Imageshack - glensresistorreplicatio

I think there may be a heat sink problem with the resistor core material and the silicone covering that was used .... can you list the materials that was used for construction so Harvey, Rosie or I can make a determination of what could be possibly wrong so we can resolve it. I suggest you may try the purchased load resistor you have and see if there is any heat generated with it to make sure all your circuit components are working properly.

Do you know if you will be able to get any oscilloscope wave form shots .... I know at present you haven't a scope .... but were all hoping

Best Regards,
Glen


************************************************** *******
EDIT - I just noticed you posted a "Ferrite" resistor core .......

Ferrite is a class of ceramic material with useful electromagnetic properties and an interesting history. Ferrite is rigid and brittle. Like other ceramics, ferrite can chip and break if handled roughly. Luckily it is not as fragile as porcelain and often such chips and cracks will be merely cosmetic. Ferrite varies from silver gray to black in color. The electromagnetic properties of ferrite materials can be affected by operating conditions such as temperature, pressure, field strength, frequency and time.

There are basically two varieties of ferrite: soft and hard. This is not a tactile quality but rather a magnetic characteristic. 'Soft ferrite' does not retain significant magnetization whereas 'hard ferrite' magnetization is considered permanent. Fair-Rite ferrite materials are of the 'soft' variety.

Ferrite has a cubic crystalline structure with the chemical formula MO.Fe2O3 where Fe2O3 is iron oxide and MO refers to a combination of two or more divalent metal (i.e: zinc, nickel, manganese and copper) oxides. The addition of such metal oxides in various amounts allows the creation of many different materials whose properties can be tailored for a variety of uses.


Could you verify that this is what your prototype "Quantum" load resistor core is made of ..... this could be a problem if it is "Ferrite"........

Hi Ash and Andrew,

Here is the data sheet for Bostik Matrix FC

This is a thixotropic polyurethane. A thixotropic gel relates to how the material is applied and essentially reacts like the inverse of a non-newtonian liquid in that it becomes 'thinner' (more liquid) when stirred or agitated. I would hope this is not the case after it is cured as certain conditions in these coils can lead to recursive microphony and that could liquefy your material.

You will note that the maxium service temperature is 80C while some polyurethanes are actually used as thermal insulation (See http://www.assanpanel.com.tr/en-us/Q...s/Attach.1.pdf) Like Glen's Silicone covering, the real temperature of your resistor wire may not be making it out to the outer surface of the material due to the very low thermal conduction and very high heat capacity of the material. I might add here that the original Ainslie group had temperatures over 50C above ambient (~20C) so your material is at its limits if these condition were to surface.

You also have two other factors of importance. You have used a stranded insulated wire. We do not know what the insulation material is around your wire, but if that wire is a type of heater wire then the insulation is probably a silicone material. It could take days of constant heat for your resistor to fully equalize and present the correct temperature to the outside world depending on how far the wire is above ambient. Next we would need to have a look at the stranded wire specifications to determine how current through the wire relates to heat. A chart like this one is helpful in determining the expected temperatures due to current flow in a tightly wound coil of the material.

Rosemary contends the energy observed as increased heat (above that expected by current flow) is partially a result of matter fluctuations which increase with the mass of the wire. So according to her thesis she expects there to be an increase in heating as the wire size is increased. This result is counter intuitive because classically we expect the heat to be caused by resistive means. Where her case could be partially supported by the classical Joule heating in the cross section of a thick wire while current flow on the skin produces the necessary induction, we are still left to determine the source of the surplus heat that seems to be present.

Also, I might draw attention to your ferrite core which also serves as a thermal sink and radiator and can adversely impact the expected temperature.

Hi Guys. This was posted over at OU. and it may be needed by Ash. I think the sequence is right.

I'm going to give a brief reference to each test and its objects - from memory - so I may be out on the actual sequence. Test 1 & 2 attempted replication of heat test published in quantum. Both failed. #3 resulted in OU. #4 again failed (evident lack of harmonic else all was the same). #5 full overunity (no evident power lost from the battery other than microwatt loss from the battery possibly due to overcharged condiition) Harmonic evident. #6 intended as control. Tested alternate load resistor and could not manage the required harmonic. Failed. #7 intended to test higher temperatures - showed results that were extraordinary but was terminated due voltage levels that could possibly stress the measuring equipment. #8 designed to remove clips - shorten leads - tidy up the circuit and then also test Harvey's bootstrapping. Results even better and both grounding and bootstrapping concerns eliminated. #9 changed the source shunt resistor with a non-inductive resistor. No difference to the waveform - but COP > 3 which was less than previous 'pass' tests. #10 designed to check the voltage deviation across the source shunt. Intensive 'dumps' every 6 minutes over 1 hour. Determined this was within the required range to allow application of the formulae developed by Harvey. Also results back to OU. Harmonic strongly evident.

This essentially means that the thesis is shown to be proven on replicated tests. Also, measurments are not the result of an inductive shunt - grounding issues - bad wiring - faulty equipment - bad probes - wrong measurement or anything that Poynty has been trying to show us. Anomalies in the waveforms persist - and COP seems to be substantially displaced with outright OU. We're busy writing that paper - and still want to test two different resistors to determine what conditions require that harmonic which is a signature that seems to be associated with these extraordinary results. The hope is to submit the paper at the end of November. We seem to be on track for this. The news is all good. It is just that until submission and review - our own excitement is relatively subdued. That acceptance is critical and we need to submit something at the required standard. But the thesis is proven. Questions persist to explain the anomalous heat signatures and waveforms - but that there are questions remaining is actually a really good thing.

And the effect - which I always assumed would be 'easy to show' proves to be a really subtle moment found when the circuit components generate a self-oscillating frequency. This, as Jibbguy has referenced - has traditionally been factored out of circuitry as undesirable.

In this possibly-related story today on Peswiki, Sterling Allen reports on a South African man, screen name is "Watkykjy1", who has built a Bob Boyce-designed hex MOSFET programmable controller PWM that he claims recharges the battery at OU potential.... Using extremely fast /sharp pulses of "0.3% duty cycle".

This sounds familiar

Essentially he uses a system originally designed for hydroxy production, to generate 6 separate high frequency pulses summed on the same signal, the idea being to get as many pulses with the fastest rise times possible.

Child Rides EV Toy on Boyce Free Energy!


This takes us into a new realm, that of writing code and programming firmware. But an enterprising person skilled in this could write an executable to do this for others (even an HTML), once it is studied and the best F's found... Then all that would be needed to control the setup is an old used laptop.

Mr. Boyce shocked the F-E world recently with his announcement that he has been fighting a rare terminal cancer. Our hopes and prayers go out for his recovery! In the "Hydroxy" Yahoo Group (which Mr. Boyce has been a major contributer for years now), many have suggested natural and alkalizing alternatives as cures.

Guys - sorry another one of those 'overview' type posts. Bear with me I feel we need to consider this point.

I'm reasonably certain that most members of this forum subscribe to the conviction that COP>1 or even OU would be evidenced through the some dramatic event resulting either in huge amounts of energy being generated from nothing - or alternatively - tapping into this field of energy and just running a work station - forever. Hints of both conditions are claimed fairly liberally throughout the forum and gains are often unequivocal if not entirely useable. The best evidence is probably in the ERR development - but that, apparently, is being carefully developed due to the hazards associated with tapping into these fields.

Our little test offers small wattage values and - while the numbers indicate over unity - the battery charge does not seem to evidence this. On all tests conducted there is an evident recharge cycle - but over time the voltage across the batteries seem to deplete - notwithstanding the wattage analysis at zero loss to the battery supply. Certainly there is evidence that it exceeds its watt hour rating. But somehow it lacks the dramatic moment associated with any claim to have 'cracked' that unity barrier.

However, the oscillating condition of the battery with the circuit components is such that the instability of that resonance renders measurements difficult. This, in turn, is coupled with the fact that the experimental constraints are limited to the measuring instruments used. What we have at our disposal - and referenced with gratitude - is what Fuzzy describes as a 'Ferari'. And he loves driving this. And we are all extremely grateful for the generous offer that allowed us to access this TDS3054C. But like all DSO's it has certain voltage constraints - and while these are nominal - they prevent any testing on those super high wattage values that I suspect you all want to see.

But this constraint aside - we still have the evidence required for the claim. But it is simply as if we have opened the door a small way. One possible advantage here is that the door is wedged open with a thesis which - albeit both skeletal and conceptual - predicted the result. As mentioned rather copiously - our hope is that this will generate the research and, more to the point, the funds for the research - that this effect warrants. Fuzzy has already secured some interest - but the wider applications - that needs far wider investment both in interest and money.

I am reasonably confident that eventually that door will be opened wide, certainly wide enough to show these effects more strongly and more convincingly. At this stage I'm just so grateful that we have something to point to - even if all the questions are not answered and even if the applied wattage is still modest. At least it has been proven and proven with instruments that are wholly reliable - on tests that are entirely repeatable - and using measurement protocols that are classically required.

It is said that extraordinary claims require extraordinary proof. I'm satisfied that our proof is indeed sufficient - based as it is on the hard work that Fuzzy has put into this and on the impeccable standards of experimentation that he has applied. With some more tweeking - and with more time - I'm also satisfied that those more dramatic effects will be evident. At this stage we're still peeking around the crack in the door and can't quite see the size of that room. But we've got our foot in the door. We just need mainstream to help open it a little wider and share some of that view.

Hi jibbguy,

about a month ago I advised user: Groundloop of this HEX-Switch claim and he immediately replicated a circuit that does this fast rise time and super short duty cycle switching claimed that is needed to make this work.

However, still to date he has been unable to get a battery to recharge using this circuit and coil configuration. The only thing left to try is the special silver plated magnet wire which he will receive soon. However he does not think this will make that much of a difference.

Groundloop has been working in electronics for 20 or more years. So if he can't replicate the effect then I would suggest we don't consider this as a valid claim yet.

If anyone has details that you beleive would help Groundloop to replicate, please do contact him.

Here is a topic at Energetic he has posted his circuit:

Hex-controller replacement

Added
here is a topic at OU that Sterling of Peswiki.com has started to which Groundloop has also replied.

Bob Boyce Hex Controller

Luc,

May I add that I also will receive the same core as seen in the videos,
together with the silver plated, Teflon insulated, solid copper wire. So
my Torroid transformer will be an very close replica. I have recently also
designed a 3 channel switch that uses the same fet drivers and hexfet
transistors as the BB controller, but with a PIC16F84A as a driver. If
anybody want the circuit drawings and pcb design files then just go
here: http://home.no/ufoufoufoufo/hexfetswitch.rar and download them.
(Files will open in Cadsoft Eagle.)

I have not built this new circuit yet. I will first try out the one I already have.
If that turns out negative then I will build the new switch also.

I apologize for the off topic post.

Alex.

Guys i joined the private B-Hex group have a toroid wound already and the 3G board(older board but still works), ill talk to Bob (i know him) about the Hex stuff and get what info i can to Luc and Alex give me a week.

Back on deck! Guys Brilliant new info/results and explanations, makes us feel like babies still on a pacifier . Thanks a lot guys for the extra help, unbelievable talent in this forum. We are learning a lot dont think we are not

K, Andrew and i are still at it. And will be till its done Here is the report i got from Andrew, @Rosie, will drop you a skype thanks for your message. I might get Andrew to trial different components will have a chat about it this weekend. I dont like our sealant and resistor, think it might be ONE prob.

---------------

Hey all,

Thankyou for your posts.

@ Rosie:
I've had the mosfet running chaotic previously, although it gets hot very quickly. Has anyone blown any mosfets by doing this? Would the mosfet need additional cooling?

@ FuzzyTomCat:
The prototype "Quantum" load resistor I constructed was based on your replication resistor (32mm diameter, 48 turns spaced 1mm, 150mm long, 10 ohms). The resistor core was made from PVC pipe cut down the side to reduce to the correct diameter.

I have a cheap LCD screen oscilloscope that will only show a waveform and some sort of indication of voltage and screen duration (us, ms, s). The oscilloscope is 10MHz.

The ferrite resistor core is simply 3 separate rods that can be inserted or removed easily. The 3 rods are black in color. When inserted, the inductance increases. I believe they are soft ferrite (no significant magnetism retained).

@ Harvey:

I applied the Bostik Matrix FC sealant by blobbing on and then rubbing it in. It was not agitated after being left to cure. Thermal insulation? Maybe I should remove the excess sealant from the top of the windings?

The resistor was constructed from resistance wire of 6 ohms per meter (3 x 5m lengths of 30 ohms in parallel = 10 ohms). The information regarding the insulation for the resistance wire can be found at 1.5mm Black Heatshrink Tubing - Jaycar Electronics (Cat# WH5530). The Bostik Matrix FC sealant was then applied over the top of this.

The ferrite core is as explained to Glen.

@ Rosie:

Thanks for the post on the various tests of the Ainslie COP>17 circuit from OU. I look forward to reading the paper you submit at the end of November.
The self oscillating frequency I believe can be achieved with the correct amount of series gate resistance?


Andrew

@Ash and Andrew,

Thank you for your post regarding the construction of the resistor. I would be very interested in this test with that device:


Get a drinking Thermos (glass construction, insulated and reflective) and place your resistor in that Thermos. Carefully measure distilled water (it is the salts in water that makes it conductive, distilled water is virtually not conductive) and fill the Thermos to completely cover the resistor. Allow the water to reach room temperature, and using a thermometer, record the temperature. Do Not Seal The Thermos.

Ensure your Mosfet has a good heat sink.

Using your 10MHz scope, set the duty cycle of your board to 50%. Record the temperature rise of the water every minute until it is stable for at least 5 minutes. If the temperature continues to rise even after 15 minutes of operation, you may wish to expand the logging interval to every 5 minutes instead of 1 minute. If the temperature continues to rise even after 30 minutes, then you may wish to restart the test and set the duty cycle to 25% instead. We are looking for a point of equalization between the work done and its dissipation. The Thermos will help to contain the energy losses of the resistor and make them readable. The per minute readings will tell us what the rate of heating is.

Another fun test you may try by increasing the duty cycle:
If you are able to get your water to boil (212F or 100C) and hold it there, you can measure the quantity of water evaporated at the end of your test and compare it to the accurate quantity you started with. Using this information: It takes 1kW-hr to evaporate 3.5Lbs of water at 212 at sea level. This is the same as saying 1.5876 kilograms of water at 100C. There is one kilogram of water per liter. A Stere is one cubic meter, there is 1000kg in a Stere and there are 1000 liters in a Stere. So it is easily 1.5876 Liters of evaporation per kW-hr (that is just under 54 fluid ounces [53.68] or about 6-3/4 cups). Naturally we wouldn't expect your thermos to hold that much water and you can do the test for 15 minutes instead of a full hour and get the same results. Also, we don't expect you to reach 1kW. Here is a helpful site for various conversions: GoConvert.com - Volume Measurements

To be really scientific, you should chill the water to 39F (4C) before measuring it - both during the fill and during the after test as this is the temperature that relates the weight to the volume. But for the home laboratory I don't think you have to be so accurate, you just want to find out if your circuit is producing heat or not.

Once you are satisfied that the resistor is producing heat and we couldn't detect it by the earlier methods, then we can focus on helping you get into the aperiodic harmonic mode that produces more heat than is expected.

Your Tri-Filar parallel resistor certainly is unique and may have a higher current to temperature curve. We could probably use the curve chart for a wire with the same 6 ohms/ft and multiply the current by 3 for your application.

Cheers,

The Hack Attack

Guys - check your computers. Our own, that is Fuzzy, Harvey, mine, and Ash and Co - are getting an attack from hell. Multiple hits from multiple institutions including - from memory - MIT, BBC, CNN, a slew of universities including NY, McGill, Kentucky, MIT, Boston, Harvard, Russian Academy of Sciences, Algonquin - sundry Instits in China, US Naval Air Facility - and others. On average about 4 hits every minute which is conservative. Some moments we get a multiple attack of about 20 more or less simultaneously.

If these attacks are a measure of interest in our development here - then I think it's reasonable to conclude that we've got a lot of interest and that its global. Golly. Until yesterday I had no idea. Just realised that there was plenty of evidence to show that info from our computers was getting out.



edit: Number and qualification.

Hi All, Rosie, Fuzz and Harvey had a great conference with Andrew i got all the data and will write it up for the PDF and post, also looks like we will getting closer to being able to rep and ill work towards some uni tests to help the data for ALL.

@ Rose
Yup, Andrew showed me the Hack screen shots, il post them here later, MIT and many universities are trying to find out how to make a COP 17 heater, they are all trying to hack in, guess they want to learn
Unbelievable wait till you see the screen shots guys. Jib, can you put them on face book?

Ash

Sure M8 Will do! But remember what they say in show biz, "Any publicity is good publicity" hehehe.

M.I.T. can't just read the damn forum thread, lol?

HEELLOOO... This is Open Source! Get that through your genius heads, lol.

Thanks Jib.Guys thanks to Harvey, Glen and Rose, here is some helpful beginner notes for all, these are going in the doc.

The original tests were set to 2.4KHz, 3.7%. The mosfet series gate resistance (100 ohms multi turn, or can be a combination of smaller value multi-turns for more circuit stability in series to make 100 ohms) has to be adjusted until a chaotic waveform shows up on the 0.25 ohm shunt resistor. This chaotic ringing can easily be achieved but there is one sweet spot where the circuit will not consume battery power but rather charge the battery slowly.

Use a 2 channel oscilloscope and line the spikes up (as per the scope screen shot shown). <100ns_a_10-16-09.jpg>



Measure one channel across the shunt resistor and the other channel across the battery. You may have to use a x10 or x100 voltage divider when measuring the battery to avoid spiking / damage to the oscilloscope. Here is a screen shot of an oscilloscope showing what sort of voltages and transients you may expect: <TEK00004.png>



You may need to adjust the frequency and duty cycle to find the sweet spot on the chaotic ringing waveform. Adjust the series gate resistance first.

Other notes:For those researching and developing: If you change the resistor / inductance value, be sure to change the frequency / duty cycle appropriately to the inductive reactance and the resistance value.

Do not put a diode / capacitor across the load resistor to collect the back spikes. The mosfet / resistor will also get hot so ensure adequate heatsinking.


Ps..here is MIT and other universities caught in the HACK sorry ACT.

They should pay attention they may learn some thing

...really?!? FOR REAL? GOD! I was waiting and waiting thinking my 15MHz piece of 80's junk wasn't going to cut it. Well I start Sunday then

Guess the paper contribution is out. Bummer.

But hey, my sil pads came in today, along with some glass tubes.

Plus I got most of my stuff in for the waterplug experiment and Groundloop's Hex But I digress...

Thanks for the links Fuzzy.

I hope you and Gotoluc will PM me your addresses, as I have some special glass tubes I want to mail you. For round 2.

David P.

P.S. Anyone want to make resistors? I have a crapload of this glass now. Only need a foot, but they only send it in 5' lengths.
