Welcome

The Martin Fleischmann Memorial Project is a group dedicated to researching Low Energy Nuclear Reactions (often referred to as LENR) while sharing all procedures, data, and results openly online. We rely on comments from online contributors to aid us in developing our experiments and contemplating the results. We invite everyone to participate in our discussions, which take place in the comments of our experiment posts. These links can be seen along the right-hand side of this page. Please browse around and give us your feedback. We look forward to seeing you around Quantum Heat.

Join us and become part of the project. Become one of the active commenters, who question our work and suggest next steps.

Or, if you are an experimenter, talk to us about becoming an affiliated lab and doing your work in a Live Open Science manner.

The data for the last week was promising but far from incontrovertible.  The excess energy was above the confidence limits, but still low enough that some unknown systematic change could account for it.

Because of hard drive problems, we ended up resetting the instrumentation and letting the cells cool down.  When we were ready to warm it back up, we took the opportunity to do do a test requested by an enthusiastic regular commenter David Roberson.

We stepped up the power on the active wire (red channel) and then stepped the power up on the NiCr wire (blue channel) till it was at near full power.  Then we cooled the cell, again, before stepping to full power on the red channel and then full power on the blue channel.

David has prepared a transient analysis routine based on differential equations and has been comparing the rise and fall of power steps to the equation model he has fit to it.

I have run the latest calibration power steps in my program and the system is well behaved in the time domain.  I got an excellent quadratic fit where the R^2 value=.999912 using data derived from the end of each of the power levels.

There appears to be a step in power out of .4 watts when the power input was 68.9 watts that occurred near the end of that input level.  The mica was running around 203 degrees at that level of input.  This result needs to be further verified.

I have concentrated my runs on cell 1.0 thus far.  The major  power steps that we planned might reveal additional information.

The fact that the curve match was excellent over such a large range of input powers suggests that there is most likely only a small quantity of excess power being generated during this test sequence.  Perhaps the cell needs more time to operate before it becomes active.

1/25/13
I just completed running my program on cell 1.1 data and it is acting endothermic according to the simulation.  I was able to obtain an excellent calibration curve fit to the quadratic equation with the R^2 = .999984 which is better than I obtained for cell 1.0.  The excess power step for cell 1.1 obtained when both wires are conducting maximum current is approximately -2.2 watts which I believe is within range of what I was seeing on earlier tests.

An interesting difference is that the excess power output of cell 1.1 with just the Celani wire driven measures approximately zero.  

When driven at maximum input power cell 1.0 was generating zero excess power  while cell 1.1 appears to be absorbing power.  This situation should be further explored.

I am working upon an alternate explanation as to what is causing the cell calibration to drift with the assumption that it might be as a result of varying amounts of IR being emitted by the wires.  A better understanding ot this issue will be forthcoming as I continue to review the system behavior.

Both cells follow the calculated time domain curves quite well and I do not detect any significant deviations.  The quality of the curve fit as compared to the actual data is remarkable.  If excess power were to be generated at a significant amount for any changing cell temperature, then the curve fit that is observed would not be this ideal.
I am attaching two Excel files for you to use as you prepare the document.  The curve fit file which is number ...FC0101 (72).xlsx looks very impressive.  This is where I took your downloaded data and used it to obtain the a,b, and c=0 parameters.  The first sheet is a repeat of the download itself while the second one demonstrates how I obtain the coefficients.
The second file is a display of the time domain responses to the large steps that you ran.  It is remarkable how closely the actual data follows the delayed calculated values.   Either or both of the curves look very good but undressed.
 

Here are two example Excel files and a more detailed write up of his methods all zipped up together.


 

Now that we are back up to nearly the input power level we were before, it is definitely interesting that both cells are showing significantly lower output than before. 

We approached where we were before by small steps.  Cell 1.1 tracked somewhere near zero P_xs, but Cell 1.0 lingered behind in the negative 2 to 3 watt range.  Think it is an exothermic phase? Is this the zero output level and our calibrations were high?

We'll let this cook for a while, I think.  Then we will attempt a suggested experiment by long time active follower Ecco; a high temperature and pressure run to test for more loading.

In other news, we have preliminary calibration data and analysis of the stainless cell in the Air Flow Calorimeter.  I will have to put that in the next post, though.  And, before I can share the data live, I would like to rearrange the website to list the different experiments more clearly.  Any suggestions?


UPDATE#1 - back to higher Pxs

So the past seven hours started with a large uptick in PXs that seamed to be precipitated by a sharp (but very small) change in T_Ambient.

This seams to have stabilised around 2.75W with spikes above 3W.

Might be good to let this one run for a while. Here is a composite long time graph (in Indian time) spanning back to the last power step ups made in post Roberson test.

Thinking a while about this change in the phase of the relationship of XPs and ambient temp let me assume, that this relationship is a possible artefact of your data aquisition board.
This is the only part in your measurements which is direct influenced by the ambient temperatures.
Please have a close look to the software/firmwa re of these DAQ boards.
There must be a correction factor somewere inside which is calculated from the ambient temp. If this correction factor is used in different program routines it could happen, that it is calculated in different manner ?
I assume this, as I saw, that you are using these boards also to control your building and the data red from your building control system is persented in °C or °F, so you must do a data conversion/corr ection somewhere in your software/firmwa re.

Ok - so i read Mario Massa's comments - what 9 years of singing latin and a bit of french can do for your Italian comprehension.. . oh and frengly.com!

It seams he has relevant skills to off the MFMP, would be good to hear if he can directly support the project.

@Robert Greenyer
I'm not speaking for Mario Massa ROB :-) I guess if you're interested , you have to double check his credentials with Celani and contact him! Which i think is an excellent idea for 2 good reasons:
- Is the only external technician (and an expert in calorimetry) that's been involved with all the 3 scientists & theri cell. And have personal relationships with all of them.
- Is the only person i know that is at the same time beloved by the 100% of believers and 100% of die-hard skeptics, which says all.....

@robiD
In my message the relevant suggestion was clearly to take infos about Dr. Mario Massa calorimetry device, directly asking Celani. Detail here are probably OT. I'll just reply once.
--------------
What you said it's not entirely correct:
- i did'nt mention a water device for the Piantelli tests but for later applications.
- from the link you provide, Mario Massa says "Perchè quando Focardi mi ha concesso di farlo (su una cella Piantelli) l'esito è stato negativo?" fast traslation: "Why the test was negative when Focardi gave me the opportunity of testing a Piantelli cell?"
- Few msg ahead he say that the tests, meaning their own tests, were made in person by themselves. So we have the embarassing situation of no results when Massa made the test himself and different (supposedly positive) results when the tests were made by Focardi. A bit more complicated scenario of the one you're suggesting

@Chuck & DS

Now we are thinking!

@Maxwell61

We are currently building a submersible cell in EU - if Mario Massa is willing to build us a calorimeter as you describe and send it to us then we would be happy to run the cell in it.

That's not completely correct. Obviously Engineer Massa will answer by himself but:
- Mario Massa made a calorimeter for a test on Piantelli/Focar di's cell but he didn't make any calorimetric measurement on the cell (Focardi did it);
- the calorimeter used in that case was a flow AIR calorimeter with a volume of about 90 liters, and NOT a water one;
- the calorimeter had 3 probes and and error of 2W with 100W input without calibration;
- the cost of 100 Euros was related to the "material" used without: manpower cost, probes (high quality), instrumentation s for data acquisition, and computer for data elaboration.
- the story is not known only by Ascoli65 because it has been written on 22passi and everyone can read it:

The italian Eng. Mario Massa, an axpert in calorimetry, after a measuerement on Piantelli's cell (results unpublished) in Piantellli's lab, built few years ago a water-based device for his friend Focardi, but left unused in Bologna University. Mario Massa is a personal friend of Dr. Celani, and recently offered to Celani to build a kind of water tank calorimeter to put inside his cell, untouched, and get bullet proof calorimetry. He claim some 100 eur as manufacturing cost. Celani did'nt go any further. If you want to know more you can ask directly Celani and, in case of interest, a contact information with Mario Massa.
Asoli65 knows the story and can confirm the mint reputation of Dr. Mario Massa in the cold fusion italian community.

@Robert,
although the cave is a nice idea, there would be another possible solution for a stable thermal chamber.
If you can use groundwater from a deep well, this water can be used to stabilize a climate chamber.
I know some wells here in my neigborhood which have a fixed temperature of 8°C during the whole year.

BR & have anice weekend !

@Robert, if you can zip the rig up in a watertight container of some stuff and toss it into someone's swimming pool or fishpond, there's enough thermal inertia there to sompletely smooth out your environmental temperature problem.

Water baths are not completely unknown in the physics lab.

@ Ascoli - The convection variation is a real issue. We took some video that I haven't edited for publishing, yet, that attempted to explore that. The air is blowing by the cells fairly rapidly and consistently. I wonder about windy days providing back pressure to the fans and making the air flow more variable. I also wonder about our bodies near the cells making a difference. However, many of the P_xs excursions happen when we are not nearby, or even in the building. Most of our work is done in a separate room when we are not changing things on the cell.

@ Everybody - Notice how the correlation with the outdoors temperature varies inversely for the first half of the graph and in phase on the second half? That is a common pattern we have seen when working with powders. The systems sometimes work in phase and sometimes out of phase with changes in the ambient and we have not been able to explain why.
We will definitely have to explore this correlation more, though. Can we identify a 'real ambient' that will represent what the cell is really experiencing? If the walls are colder and being a radiative drain on the cell, then how much? Is the cell being directly modulated i.e. is there a linear relationship? Or is it a triggering sort of thing? Are the in phase and out of phase relationships caused by being on different sides of a "sweet spot" of energy output?

I am sure everyone can add questions to this, also. I'm really looking forward to a more sensitive cell in a precision temperature calorimeter.

@All

Regarding environmental temp variation and possible implications... maybe now we know why the Italians have a test facility so far underground.

Anyone got an old ice well or cave we can use... I guess we are looking for an underground lair for our experiments. That would be so cool... literally

I remember caving and going down old slate mines - they were often at a rock steady 4 degrees regardless of time of day or season and had huge caverns.

I guess to be certain - we might have to become trogloditic cave dwellers in order to test the New Fire - just like we imagine how the old fire was first used. How apt.

@ Ryan
Density correction removes the gas leaks drift from the P_Xs. What remains is a nearly horizontal trend with some positive excursions. Most of them begins with a sudden increase followed by a gradual decline.

This is my explanation. The cell is very sensitive to the speed of the outside air. The vertical orientation of the cells facilitates the formation of convective cells that tend to grow and to strengthen over time. This results in the gradual lowering of the temperatures and thus P_Xs. When something disrupts and breaks these cells, for example the presence of someone around the cell, the external recirculation stops suddenly, so T and P_Xs rapidly rise. You should compare the times when P_Xs grows with your approaching to the cells.

The Celani graphs are affected by similar problems, but to a greater extent: fusionefredda.wordpress.com/.. ./... # comment-11064 (I hope Google translate does a good job).

I tried, but charts aren't very readable without some sort of filtering I am not able to perform at the moment.

In addition to a correlation with ambient temperatures, there should also be other overlapping ones (such as with pressure) which make eyeballing them more difficult.

@ Ecco - Can you grab the T_a1, 2, 3 from the extra sensors test and overlay them? They are just additional air temperature sensors around the cells. And could you get the T_Board on it? That is the temperatures sensor right on one of the data acquisition boards.

The one thing the solar panel temps do tell us is whether it was sunny or not.

0 #65 Ryan Hunt 2013-01-30 17:41
@ Ecco - nice work. The Panel Temperatures are the solar thermal panels on our building and can be ignored for this purpose. The outside temps and the P_xs do seem to correlate somewhat, don't they? Could you try to fit the other run from earlier in the month, too?

@ Everyone - I just pulled the data for the outside air temperatures here at our research campus. Would anyone care to see if this correlates at all with the P_xs? It's a long shot, but should be explored in case it is changing the wall temperatures and radiatively coupling to the test cells.
The data file is here

0 #62 Ryan Hunt 2013-01-30 16:10
@ Ascoli - It appears to me that your analysis can account for some of the measured P_xs, but still shows some times of positive P_xs and supports the general trends. For the periods when it was positive and "running" for a while, it really gave a very similar shape to Celani's graphs, didn't it?

0 #61 Ryan Hunt 2013-01-30 16:03
@ Bruce - The data points are generally between 2 and 8 seconds apart (up to 40 seconds when we had a data wire problem). We do have a scope and spectrum analyzer that we got with the thought of looking for RF, but we have not had enough time to play with hit, yet.
