.99,

I would interpret Rosemary's response in a similar way.  It would, however, eliminate all ambiguity if Rosemary would confirm that the schematic in the first paper (Exp Evidence...) is indeed the correct one.

Hello picowatt

Not sure why you need me to answer this when Poynty's reply and reference covers the question.  But far be it from me to deny you and Glen and TK the opportunity to fill this thread with another five pages of erroneous discussion.  I'm sure that you can none of you help yourselves.  It seems that the compulsive need to repeat everything is parceled with this same compulsive need to deny efficacy.  What's particularly intriguing is that this thread seems to be getting an average of 5000 hits a day.  Clearly our readers find your questions and answers as entertaining as I do.  Which just goes to show.  Even our trolls have their value.

Rosemary,

It would seem to be much easier for you to just state, "yes, paper one is correct" than all that "commentary".

What on Earth did I do to deserve that response?

So little miss "SUPER TROLL" ... Rosie Posie ...

So the device schematic from paper 2 ( ROSSI-JOP-2- PDF.pdf ) is wrong and the "correct" device schematic is in paper 1 ( ROSSI-JOP-1-PDF.pdf ) a typo you say.

The device schematic in paper 2 ( ROSSI-JOP-2- PDF.pdf ) the same device schematic posted in your "SUPER TROLL'S' BLOG site http://newlightondarkenergy.blogspot.com/2011/04/109-simulated-circuit.html ( Simulation Schematic.jpg ) ( ROSSI-JOP-2-PDF_Q1_Q2_x4_.PNG ) were these device schematics used at "ALL" in your papers 1 & 2 or some other testing of yours anywhere ?

Yes or No ??  ???

Is that "ONE" question to hard now ....

CHEERS,
FTC

Basic FG offset function:

You all have no idea how hard it is to fake this stuff. I had to use CGI and a room full of renderers to pull this one off.


OH... it's almost six am. I've got to hurry.... it's almost time for me to reset the ROSIE TEST PREVENTION broadcast device, which radiates Tesla technology longitudinal scalar waves that keep Rosemary from thinking coherently and performing a TEST of her batteries for yet another day. I'm going to be boosting the power soon, though, so that a single linecast will prevent her from testing for an entire week.

(The grubby nails are because I spent literally _all day_ Friday replacing my car's air conditioning system. I vacuumed the residual R-22 out, replaced the compressor, condenser, accumulator, orifice tube with new parts, flushed the evaporator and hoses with dl-limonene followed by compressed air, replaced the  highside switch, the compressor-mounted switch and all the Schreder valves, all the o-rings, changed the fittings to R-134a standard, vacuumed out the system for a couple of hours with a 2-stage pump, recharged with 8 oz oil and 32 oz R-134a--- and now I have blissfully cold air blowing out the airholes in the cabin. And I still found time to re-actuate the PoserPreventer.)

Yes TK.

That gradual ON and OFF is what I mentioned earlier on about your wave forms getting close, but without that characteristic. You didn't understand what I meant then, but you do now.

With the use of your delayed time base, the evidence is there, you got it. ;)

.99, what's the frequency of the oscs in the sim waveform shot? I can't read the timebase on my blurry copy. I'm consistently getting "approximately exactly" twice the frequency stated by the presenter in the video which relates to Rosemary's claims. This is confirmed by both the "manual" method of estimating freqs from the timebase, and also by direct hookup to the Philips PM6676 counter (an excellent performer, by the way: robust, stable and accurate.)

(Since we are now agreed that the "first" paper's circuit is the correct one to use, and since it is THAT circuit which was used in the demo video, I see no reason why the video isn't a valid topic for discussion and info-extraction.)

Rosemary,

PW
She's beginning to detect a hint of scepticism in your endless insistent demands for an explanation of unexplained features of this open-source, community-development project. So she's starting to turn on you.

I'd like to hear her explanation of why one battery was removed from the stack, for the second part of the video which used the now-known-to-be correct circuit, where high load heat was demonstrated. Why did she only use 48 volts for that part of the test? Wouldn't her ...  things ... have gotten even hotter had she used the full 60 volts ? Or the _actually full_ 72 volts she often reports using? Wouldn't that have been even more impressive than showing a non-immersed water heater element getting up to a mere 190 C?
(You do remember her saying that her MOSFETs don't heat up, don't you?)

Why in the world would one drop the voltage for these high-current tests using the "approved" schematic and circuit construction? Was there some kind of problem?

But either way - as TK has shown - it gives precisely the same result.


Note the distortion to suit her purpose. What I said and demonstrated was that there is little noticeable difference in the waveforms. There is more or less fuzz on certain portions of the trace and the feedback oscillation frequency is different, but not significantly so. But there is a much more important difference that has practical implications for the circuit's live performance.... and that involves the heat and current handling capacity of the mosfet(s) that is (are) turned on by the positive-going gate drive pulse during the high load heat mode of operation.
This is very different from me saying or showing "precisely the same result".

Why are four mosfets on large heat sinks, yet the lone mosfet is still on its bit of aluminum u-channel? Considering how the circuit actually behaves, the second schematic makes more sense (even though they didn't manage to use it for the video demo). So I am VERY happy indeed that Rosemary has decided that the FIRST schematic is the one to use. Remember, replicators: your Q1 mosfet must be on a small bit of U-channel.... and you must use 72 volts at some point, sustaining a load at high temperatures by using a positive-going gate pulse of 12 volts, just as Rosemary has shown. Oh... wait, sorry, she never showed using 72 volts, only 48.

TK,

As I recall, the actual scope shots show a Fo of about 1.3MHz. I get about the same in my simulations.

TK, just an FYI:

For the video demonstration, Rosemary and her team had moved Q1 to a heatsink of lower Rth compared to the U-channel heatsink. It's still not nearly as large as the heat sinks used for Q2-5. See the attached.

There is somewhat of an enigma about this "high heat mode."  Assuming that you are looking at a "correct" data capture where the Q1 MOSFET is functioning then you have the gate drive high and the CSR shows significant current flowing through the circuit.  There are no oscillations so I have to assume that the battery voltage is stable.

So during this part of the cycle you are looking at a 100% conventional setup, a single MOSFET, Q1, switches on and DC current flows through the load resistor and the MOSFET.  Certainly there is a likelihood that the MOSFET could be overstressed and is dissipating more power than you would like it to, but everything is 100% conventional and the DSO should record positive power during this phase.

Then if you go into oscillation mode and the other four MOSFETs start to spasm, isn't the implication that the DSO is recording enough "negative power" to completely compensate for the positive power recorded during the Q1 ON phase?

Again, I think that you are still overlooking my sticky point.  The schematic in the first paper IS NOT the true schematic.  The error is that the schematic in the first paper shows the function generator grounded before the current sensing resistor, but in fact I believe that the function generator is grounded after the current sensing resistor.

What do you have to say about this issue Rosemary?

My theory is that in the original single-MOSFET setup you had the function generator grounded after the current sensing resistor.  Then when you added the four extra MOSFETs and miswired them, the function generator remained grounded after the current sensing resistor.  It did not occur to you that the four extra MOSFETs would conduct current straight through the function generator itself.

Is this what happened Rosemary?  You have to give us the straight goods.

As a reminder to all.  Poynt reverse-engineered the schematic and I confirmed that all appeared to be correct.  I did not literally see where the function generator ground lead was clipped in, but I am still assuming that the ground lead was clipped into the same place were all of the scope probe leads were clipped into, and that was the battery ground node.

So my theory is that once you go into negative oscillation mode, you have the wildly fluctuating battery voltage and an AC signal on the current sensing resistor that is not even the battery current.   The DSO in looking at these two junk signals saw what appeared to be very high negative power.  This false negative power measurement was enough to wipe out the positive power that was measured while Q1 was on.

I will repeat my contention:  The true battery current waveform during oscillation mode is unidirectional pulsing DC.   However, what is seen at the current sensing resistor is symmetrical AC that is AC-coupled through the gates of the Q2-Q5 MOSFET array.  Those are two radically different waveforms.

TK,

Thanks... I guess I need more cabling amongst my batteries and suchlike.

 Also thanks about the HS... I didn't notice that they had used a bit better heat sink. I wonder why... since Rosemary has said several times that her mosfets don't get hot.
 
 BTW, does that look to you like her probes are attached at a "junction"?
 
 But she said,

OUR Scope probe positions are NOWHERE NEAR A JUNCTION.  There is therefore NO CONFUSIONS about our results.

 Oh... that's right, the video only "relates" to her claims....


Meanwhile, back in La-La land..... After one of my recent videos where I show the TarBaby configured according to YET ANOTHER "wrong" and disavowed schematic (the one in the second paper) Rosemary had a lot to say, all of which was garbage, but this bit in particular is so easy to refute I just couldn't leave it alone.

Rosemary said,

And colour code your 'FET wires - at LEAST.  Or something.  Or try and show that they're properly connected.

Here is a photo of my 'FET (sic) wires, as they appeared in that video (and still appear this morning). Notice anything interesting.... like the fact that Rosemary ONCE AGAIN is totally wrong about what she thinks she sees in my video and has no hesitation to post blather without checking her facts. But of course she will tell us that it is MY fault that she made this egregious error, because of my shaky cam and low light. And I will laugh and laugh.

Rosemary.... your video playback software DOES have a "pause" button, doesn't it? Perhaps you can get a ten-year-old to point it out to you and teach you how to use it to examine videos carefully.

Rosemary:

I had another look at the clip and I realized that at the very beginning of the clip that you can clearly see that the function generator is grounded to the common grounding point for the probe grounds, which is the battery ground.

So now we are looking at another scenario:  When you wrote your two papers Rosemary you realized the mistake with respect to the grounding issue for the function generator.  It would not be correct to show the function generator bypassing the current sensing resistor because the current sensing resistor is supposed to be "pure" and account for all of the battery current.  Therefore you intentionally changed the simplified schematic diagrams in the papers to show the "negative" signal from the function generator connected before the current sensing resistor, even through you knew that this was not really the case.

Is the scenario that I just outlined above true Rosemary?

The simple fact is that you probably thought that it was a minor and benign change that nobody would notice and it would not really make any difference - or so you thought.

But the fact of the matter is that it makes a huge difference.  In the correct configuration as per the actually built device you have an AC-coupled signal going to the current sensing resistor.  There is no DC path at all in negatively offset oscillation mode.

It wasn't a benign change that nobody would notice, it's a complete and total screw up.

@MH: Good for you for finally pointing this out. I've used both ground positions for my TarBaby tests, but I've hidden the results out in a desert somewhere so Rosemary can't find them.

Either that or they are posted on YT, one or the other.

But as we know, the video only RELATES to the claims, the claims themselves and ALL THE CORRECT DATA AND SCHEMATICS are included in the papers. Aren't they?

And of course we know that DSOs are infallible, so what are you talking about with DC pathways and all that? It's all explained perfectly clearly in the papers using diagrams like the one below.

@MH: I wonder if you could do a similar analysis (similar to YOUR earlier one I mean, not hers) using the "high heat" mode with a positive gate pulse of 12 volts from the FG, on a diagram instead of the fine verbal description earlier ......

 8)

(You know... it is interesting. Every reference I can find about power measurements on switched mosfet circuits says to use the mosfet drain voltage and source-drain current in the instantaneous power computation. Yet it seems that they have left out the drain voltage completely in the papers (but not in the video, where it reveals much.))
