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.

We just commenced loading of the Hydrogen into the Celani wire.  We are loading at 4.6 Bar and 170C.  We started at 3.5 bar H2 at room temp to be comparable to calibration runs with the Isotan wire in Helium, The Isotan in H2, and the just completed Celani Wire in He all starting at 3.5 Bar.

 

One early thing to note is that the resistance of the wire is dropping off quickly.  Cooool!

 

Interesting data from the Run #2 in He starting at 3.5 bar compared to the Calibration run 3 in He at 3.5 bar

The measured cell temperature is running noticeably higher with the Celani wire compared to the Isotan.  I haven't had time to do the same comparisons with the other temperature sensors.  Look for that soon.

Meanwhile, the impedance remains interesting with every run.  This time we see a dip in a similar place to the Isotan, but the overall slope remains positive.  Fascinating!

Thanks Paul. I initially discounted such sharp voltage increments as I assumed you would be careful not to place unnecessary thermal shock on the Celani wire.

Quoting David Jones:
Perhaps I can answer my own question. Are the resistance measurement jumps due to the wire temperature being increased in two discrete steps?

If yes - my question is irrelevant.


The answer is yes. Those steps were manual adjustments to the voltage.

Perhaps another way of stating the problem of graph 1311 is that possibly, external electrical power equipment switching on or off are introducing errors into the resistance measurement at a magnitude comparable to the effect you are looking at.

A critical reviewer would not be happy with that.

In the top graph (resistance of wire verses time – Records 1311) you have instantaneous increases in resistance. This has to be an experimental artefact - to my mind anyway. Would you have any idea why this has occurred?

A critical reviewer of your experimentation would spot this anomaly and would want this cleared up - as the implication is there is an error/fault in your diagnostics.

Hi Peter, at this stage we are just working to replicate and extend Celani's work. There is much debate about the science - we need to first show incontrovertibl y that there is an effect.

Congrats very professional approach and execution!
Do you have a working hypothesis, WHY it works- if it works?
Wish you success, positive results beyond any doubt.

Quoting Valac :
Could you please clarify how the Impedance or Resistance are being measured?

If it was a DC resistance measurement (assuming current supplied from a Switch-mode converter) could you please publish the ripple current(s) spec for uncertainty calculation?

If it was an Impedance measurement (resultant of real component, reactive component and the theta angle), could you please publish the reactive component(s) of Celani's wire as compared to control wires, at fixed temperature, in air? and supply frequency? angle?


The mainstream critics will have to look into these.


The impedance is being measured at DC by measuring the ratio of voltage to current.. As such it has no phase angle and is the same as resistance.
I don't have ripple numbers handy but it is in the millivolt range, The A to D conversions are averaged for several seconds, mostly eliminating ripple.

The impedance of Celani's wire continues to drop with the H2 loading.
We are now reaching 15.5 ohms, starting from 18.4 ohms.
R/R0 is almost 0.84 now.

By looking at the slope asymptote, we should be able to get the wire down to 15.0 ohms.

Quoting Arnaud:
Is the loading by indirect heating or by direct heating of celani's wire ?


By comment #3 of Robert Greenyer, indirect heating.

Any update on the resistance? Does it continue to drop? Maybe you have another graph perhaps?

Sorry to bother you, but I caught an idea from other experiments...

I've read so many skeptics moaning about the bad measure of temperature, hotspot, mistakes.... One mode to have more stable result about thermal measures is to work in isothermal mode with compensation.

I've read paper of mckubre
lenr-canr.org/.../...
that propose that classic isothermal mode.

I've read similar method in captors, like MEMS.

for you the idea could be to stabilise the temperature of the reactor to a fixed value, by controling the dead nichrome wire heating, while you make the active wire power stabilized.

you will have to make all the software change, use a very efficient control method to stabilize heat quickly without bouncing... but this can shut up some critics... and I'me very pessimistic about possibility to convince mainstream.

@7,

Thanks for the clarification! I figured it was likely beforehand. I would expect the higher impedance of the Celani wire would mean a higher temperature for the same current compared to the other Isotran, but could always be wrong. As you point out, at least it's easy enough to compensate for with a slight adjustment.

This is fascinating work!

Some more thoughts:

I think I remember with the treatment Celani's wire went through, it increased the amount of oxidation in the wire. Oxidation should increase the impedance of the wire, so that may explain some of why Celani's wire has a higher resistance in He than the Isotran.

The other potential factor I can think of are the micro surface breaks in the Celani wire may also have the same affect.

Now, why there's a dip in resistance at a certain amperage... maybe that is some sweet voltage/current resonance spot for the wire. Otherwise.. I have no other guess as to why there's a random dip around 2 amps in both wires in inert atmosphere.

Run #2 in Helium was before the loading.
In the data from Helium runs 1 and 2 with we are seeing higher temperatures achieved by the Celani wire. That means the correlations developed with the other wires may need some adjusting to be valid. We'll see.
