me356: Reactor parameters [part 1]

Quote from JAROVNAK

Could search out resonance, process responsiveness/ LENR start / stop / control - identification of process response time constants. Easily implemented in Raspberry & obtain bode plot at different hold or operating point - very useful info!

The Lugano report refers to using 3-phase power to excite. Most of us do not have that in our homes, however it is pretty easy to create. Using a variable frequency drive (VFD) one can use a single phase input and actually get a true three phase output. The only caveat is that one must use a VFD that has twice the power rating as the desired 3-phase output. For example if one needs 1.1 kW output, then you need to use a 2.2kW drive when run from single phase. Also, the max voltage out 3-phase will be equal to single phase voltage in. So if you input 230VAC single phase, you would get out 230VAC 3-phase. The output of a VFD is rather "dirty" which may be of some benefit. Some, but not all VFD's are rated for single phase input.

TRIAC interjects a lot of harmonic content that seems helped Parkhomov's successful replications & Bob Goodyer's problems in not stimulating the lady LENR with his VARIAC source based attempt & the appearance of LENR in Alan's last GS3 intial run when TRIAC was power source. Subsequent calibration problems which Ged, Sanjeev & I saw were related to using the active fuel element. The calibration with the unloaded fuel element clearly showed the problem with the previous attempts at calibration with the fueled one as I believe Ged recognizes. The true COP estimate would be the unfueld calibration subtracted from the original temperature trace. There were no instrument problems like moving coil & I'm sure Alan will come around to that conclusion. Hope there was enough ash to give us positive results of Lady LENRs visit. At least i am convinced. Your discussions shed light on the micro burst formations & nuclear process from fuel to ash which is beyond my analytical capabilities. Simulating reactor decay heat & things like zenon poisoning years ago we used time constants determined by decay product specialist in our dynamic reactor control study simulations work & how they were determined is beyond my understanding but seem to be so important here now ie subthermal ultra low momentum neutrons involved in micro burst & thermal expansion controlling this process to our control advantage & the nuclear decay constants giving us the longer term time effects also (ssm buildup in time etc). Wish we could see inside fuel element somehow with Hydrogen pressure spectum response analyser, IR camera down pressure sensor tube looking at light in micro burst process, etc. Would be Nice to have results of sweeping sine wave power input in power source & IR temp gauge me356 used. Maybe sweep frequency of .1 to 50 hz would give us a good picture of break points in subsequent bode plots of how the process works, just maybe? Lot of details still puzzle me but are becoming clearer in my mind based on my long working career with current nuclear power plant controls years ago. The National Labs played a leading roll in supplying us with basic process response data necessary for our work in control & protection of various reactor designs. Billions spent in that effort & recording & preparing engineering support reports we don't have the luxury of here. Thanks for your discussions, they sure help me in my thinking & partial understanding of what's happening in the Hot E-Cat & fascinating replication attempts of MFMP replication experimenters. Thanks again.

In past the Hot-Cat was tested by Rossi-Penon when it was supplied simply by a single phase Variac (fixed grid frequency) and they said that it worked fine, therefore TRIAC and "sweep frequency" are not required.
These are useless speculations in order to looks like they are absolutely necessary.

Quote from JAROVNAK

Did note that multiple steps were made to input power from what looks like a VARIC source as you said on temperature ramp rise. Those steps have a tremendous amount of high frequency content in them you of course realize, No? Just as with Chinese current DC records of (ssm) periods of LENR presence, I believe they came after steps in DC source exciting Lady LENR in china recently Henry. Interesting also that simulation failed to pick up long term decay of temperature as Rossi test was shutdown indicative of (ssm) long term decay products present and have noted in almost all current testing end of test results. As I have been saying .1 to 30 or maybe 60 hz sweeping sine wave would tell us a lot more of what the LENR dynamic response is. Stimulation could even lie above that frequency range. Think we would be negligent to NOT explore Hot E-Cats frequency sensitivity if we could get a handle on this. Robert Godes in his Brillouin product development even specifies use of EM specific frequency of excitation in his patent & has cued Rossi in that direction in Rossi's latter (2012) work & even Rossi switched to noisy TRIAC source. By the way do you have a background in controls system design & engineering by chance? Like I said I did not look in detail at the simulation or 2012 test report till you just called my attention to it now & I thank you very much for pointing out your reasoned explanation questioning my direction. There were questions raised by testers in 2012 as to measuring their noisy AC variable amplitude input signal. Remember their data acquisition system was sampling at only about 1 second periods - hard to see much content above 1 cycle without severe aliazing data. I really appreciate your input & questions you raised concerning my thinking & logic. It is always good to talk these things out. Liked presence of PCE 830 test instrument but dont understand their comment about it no measuring DC current. VARIAC is all ac & PCE 830 power analyzer should have given then good frequency spectrum info, No? As well as power. Please look again at Lugano test report with picture of power spectrum recorders input courrent shape as well as frequency content harmonics. I like the Lugano report & look to it being vindicated in the near future, I am sure of. Thanks again look forward to your reasoned response. Please go to Rossi blog tonight with me to see further discussions on importance of frequency to process operation & testing.

In the calibration published on june 14th, we see a large temperature step at 280 C.
Reactor parameters
We see the same in active experiments from Parkomov or from MFMP, at several temperatures.
When water boils it stays at 100C. That seems a phase transition when something melts or evaporates. Perhaps also in change of cristallisation.
That could inform us about what happens.

Quote from Henry

No, each Variac voltages have been described as stable for dozens of minutes.
"Tremendous amount of high frequency" is a your fantasy and speculation, harmonics were rare and weak when voltage increased using a Variac.

Just some more thoughts!

Thank for your references from the past as (ssm) LENR does accumulate ash! Also take a look at some newer test fueled vs un-fueled elements in series! Rossi blog LENR 24hz lenrforum Henry?

24Hz is camera's frame rate, do you like illusionism games or are you an illusionist?
I fear you are another "scientist" right now ready to improve Rossi's team.

Any guy completed successfully his high school knows that heat (or worse excess heat) cannot measured in that way.
Did you complete it?

Quote from JAROVNAK

"Research has developed design features and proprietary processes providing longer lasting, more reliable products. Particularly important is the high-temperature foundation material bonding the coil securely to the core assembly. This material (which has a high thermal transfer characteristic) dissipates heat from the brush contact area, increases the heat-distribution of the core itself and provides the transformer with greater tolerance to transients and short-term overloads."

Another point for us to ponder Henry with your inquiring thoughts is that Hot E-Cat maybe stimulated in the 20 to 30 hz range & the 60/50 hz steady VARIC is above that resonance, no? Only when you put step inputs by turning the power output control do you generate harmonics above & below that frequency from brush rotation on the coil, No? This may have generated a lot of ssm energy during 2012 Hot E-Cat test you referred me to. One gets only the big LENR (ssm) energy micro burst at the resonance frequency. The sweeping sine wave input I was suggesting would tell us, that is you & me, No? Why would you not want to do that test, is beyond me. Oh, and the high school in next town over had advanced everything in their curriculum, but alas I could not go there even knowing that & many of my friends attended there to their great educational advantage. I am truly sorry for myself for a long time Henry. Where did you attend high school & you must of had some advanced courses otherwise you wouldn't ask such nice questions.

Jim Thank you again for your inquiring, reasoned questions that have lead me to inquiries I should have thought out more precisely before. And you are right I am a dreamer & the water droplet video was a put on!
Cheers Henry!

When a sinusoidal voltage doesn't change its amplitude for dozen and dozen of minutes you are in a STEADY STATE condition and NO harmonics exist, in addition Variac is a low pass filter.
Rossi-Penon test has been performed using the fixed grid frequency they didn't change the voltage for a long time during large part of test and operation.
A smooth voltage step (quite limited changing of Variac position) doesn't produce "huge harmonics" you said and in any case absolutely never comparable with aTRIAC.
Your words "maybe stimulated in the range 20 to 30 hz range..." are still your usual speculations without write any formulas, put levels, numbers or give evidences, just to say something.

"This may have generated a lot of ssm energy during 2012 Hot E-Cat test you referred me..."
ssm energy? Is a new type of energy you studied at your high school?
Maybe more skilled in petitions.
Cheers.

Thanks for very interesting comments.

Here is my fuel container in the attachment before fuel loading.
Both screw-threads were sealed and mounted so it can hold firmly.

In two weeks new SiC elements should arrive to me so I will be improving the design.
The biggest issue for me is to make container for the fuel container that will keep Hydrogen gas inside and all will fit in the SiC element / heater.

me356, Thank you for the picture of your fuel container. Is it just a threaded tube with standard stainless cap screws plugging the ends? Very simple design, I hope it works. What do you plan to use to seal the threads and keep it hydrogen tight?
