Mathieu Valat's Mass Flow Calorimeter was developed specifically to test Dr. Celani's wires. Mathieu devoted well over a year to design and construct the system, with help from J-P Bibberian and support from National Instruments and Bronkhorst Tech.

You can see the interim report on the system here:

goo.gl/tl9NHz

Work was temporarily suspended while the lab was moved, as previously discussed in another thread. Calibration and debugging was well under way before the move, and we hope this project can be resumed in the near future.

WHICH hill ... Mayacamas? I'm in Lake County.

My comment was based on the website link you provided at the start of this thread, which shows Campbell California. That is about 25 miles from me.

If you have moved, please forgive my mis-statement. Lake County is a fair days drive from me but my offer still stands.

I referred to myself as "The Third Alan" considering Alan Smith as #1 and yourself (Alan Fletcher) as #2.

This will also leave me free (if I have no assistant) to read the liter-counter on the pump.

I volunteer to help - I'm just "over the hill" from you.

Anyway, good luck with your silly efforts. I predict nothing will come of them

re the .RAVI files for the Feb 2015 Thermal Validation still around? Small segments of Optris video from that test would be useful, if possible.

Unfortunately those files appear to have been lost, possibly due to the ground fault that damaged the Optris USB interface mid-way through the test in Feb. 2015.

That lack is precisely why I repeated the measurements in April 2017, using the same (repaired) Optris system and a fresh (NOS) Dogbone replica made with the same materials and dimensions.

Quote from Paradigmnoia

Maybe someone from MFMP can make a download link for the Thermal Validation .RAVI files so we can all play change the emissitviy and COP game with the same data

Back to the lab now.

Quote from eros

Spec says sensitive to down 7kev.

Is that correct?

The one we used did not have the external probe. The spec may claim "sensitive down to 7 keV" but in my experience a GMC with such a small internal tube won't respond to anything below around 50 keV, and the peak response will be above 100 keV. The stock GMC320+ is a similar unit, and its lack of response to low energy gamma is what prompted me to upgrade it with the LND pancake tube.

Alan Goldwater's GCA was modified to use a LND pancake detector.

Correct. It is a GMC-320+ coupled to a LND7317 pancake tube. This combination is sensitive down to ~20 keV, with peak sensitivity at 80-150 keV. Typical background count has been around 40-50 CPM at a variety of locations. At the me356 site it was a bit higher, maybe 50-60 CPM. Some periods of 80+ CPM were seen during the test, as shown in the Dashboard screen capture above. A second GMC with a smaller cylindrical tube was also used, and its output count averaging 25-30 CPM is also available in the main (Labjack) data file.

The He3 neutron detectors were found to be quite sensitive to the RF apparently emitted by the reactor. Neutron bubble detectors were also used throughout the testing, and showed nothing above background of ~1 count per 8 hours. Both microwave and ultrasonic spectrometers were also used, and showed some detectable activity above background. That data is or will be included in the experiment archive.

This is an extraordinarily comprehensive and well-documented paper. The details included of the instrumentation and calibration procedures are especially impressive. I haven't read past the first 20 pages, but I expect the findings will be equally well presented. Not that I'm a Mills believer (yet) but it's hard to fake something like this.

Quote from Paradigmnoia

I suppose I can reveal that 25 kg of Ni62 (if it could be made) would be in the general vicinity of half a billion dollars, based on my quote from that supplier.

That seems too high. MFMP got ~70 mg of 62Ni for around $1k, IIRC. That would be less than $15k/g, compared to $20k/g for your quote. Maybe there's a reverse discount for quantity...

Quote from BTE-Dan

Pressure reached 40 bar. (Yes, I have needed safety precautions in place.)

Nice work Dan. You're probably aware of the MFMP "Bang" experiment a couple of years ago. We didn't yet have pressure measurement in place, and we did exceed the yield strength of a similar Alumina cell, with dramatic results.

Following that experience, I attempted to calculate the internal pressure from known physical parameters. I didn't consider the effect of hydrogen loading in the Ni fuel, but the calculation was a useful exercise. My report is available at https://drive.google.com/open?…xJkjesxe4kZEdjWnJ0QW9wME0

and the calculation spreadsheet at https://drive.google.com/open?…xJkjesxe4kTld3cXhyUDRibEU

Feel free to plug in the dimensions and fuel mass of your experiment for comparison.

Quote from robert bryant

1. Axil said "the electrostatic high voltage field had induced a input current of .105V "

Do you mean "induced an input current of 0.105 Amperes"?

Currents are not measured in volts but in amps

I think what is stated in the paper (as quoted by Axil) is that they measured a drop of 0.105 volts across a 1 ohm series resistor. This corresponds to a current of 0.105 amperes. If the steady-state voltage across the cell is really 100 kV, the input power would thus be about 10 kilowatts.

So I strongly suspect that the high voltage is applied to a third electrode, to start the plasma. Once the plasma becomes conductive it could be thermally maintained by a much lower voltage, perhaps 500 v.d.c 0.105 amperes or ~50 watts of input.

This is a fairly common engineering trick. See for example:

At last, Weaver has said something with useful semantic content.

That is a quote from Frank Zappa, from the album "Apostrophe". The hit song in there was "Don't Eat The Yellow Snow".

@BobH

I used some left over solution from a PC short run I did about 20 years ago. It was originally about 1 liter of solution made up from a bag of crystals bought at Jameco or Frye's . The unused portion was stored for at least 15 years in a soda bottle (PET?), in what used to be my darkroom, now the lab kitchen.

I had good results in surface cleaning of Ni foam in FeCl3 (PC etching solution). See the images at:

Ni Foam hacking II

Compare that surface morphology to the First image at Substrate Micro Structure, to see the effect of surface etching.

BobH has also used acid etch (HCl) on Ni micro particles. My impression is that Ferric Chloride is pretty aggressive, and low concentration dilute solution would be needed to avoid Carbonyl Ni dissolving completely.

Quote from Forty-Two

Didn't SKINR try to replicate (and fail with) the "MFMP signal"?

From what we were told and shown, SKINR did not use any radiation detection, nor did they replicate our protocol, despite my sharing my lab notes and all details of the experiment.

My impression is that it was a poorly designed and run test, with many important details ignored, and no data published.
