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.

There is a great opportunity to learn everything about the project and actively help it with every day progress. The great feedback from some of our volunteers will tell you more. Now we search for someone to come to HUG, Minnesota to spark the Sparky cell and see with own eyes whatever exciting will happen.

After trying the wire repair, we loaded the wire overnight at a few different temperature steps. The cell was heated by the NiCr wire.  That means that for this phase of the experiment, T_mica is a pretty close measure of the actual temperature of the Celani Wire.

The Impedance went down to a low of 16.37 @ 202C from a starting (from this loading) of 18.23 for R/Ro of 0.898

When the wire was later cooled, it went down to a low of 15.68, for an R/Ro of 0.86.  

The Ambient was steady within +/- .01C

The Excess energy rose slowly from and average of -.5 to 0.  This could be attributable to the drop in Hydrogen pressure, but it is interesting to note that we are now in the range of performance we saw in the very first runs with the Celani wire.

 

Next Steps:  

Try a run at 3.5 Bar of 75%Hydrogen, 25% Argon using both wires at the same power level we were at yesterday.

Quoting David Roberson:
In my estimate, it most likely does not matter which wire carries the current as long as the active one reaches an adequate temperature.


In a papre (ICCF17) Celani siad that yes indirect heating works, but that heat is not all, and direct current seems to make "excitation" more efficient at same temperature...

We should also remind the claims of Brillouin and Defkalion who clearly state that heat count, but some non thermal energy can help to trigger...

about the light idea, like I said before one technique to detect if it have an effect is to make it periodic or pseudo periodic, to capture correlation from the noise. system is non linear, but one can catch correlation even from uncertain corelation.

anyway to the team: keep going! making it work first is the key... after than can detect what make it work... make it more precise, more efficient, more variable, more reliable... after... :sigh:

>When we turned up the temp with both wires we saw the impedance drop first, then start to rise again.

The increase after the drop has been very marginal however, if you check it in context. It can probably be safely regarded as constant:



I personally get the very slightly increasing behavior as a sign that active the wire can't load any more hydrogen in those conditions and it's behaving like a normal wire. Now, it would be interesting to see what happens by repeating the vacuum-loading cycle again with the same power setting. It appears Impedance_red is quickly hitting an asymptote.

I wonder if it's just really "shock" that it needs, or if by loading, cooling and vacuuming in reality you're also taking out impurities on the wire (oxygen?) which prevent deeper loading. If the latter is true, then it might be an idea trying to heat the wire under vacuum (you'd need to be very careful).

When we turned up the temp with both wires we saw the impedance drop first, then start to rise again. When we review Run 1 on Nov 12, we see that we were absorbing quite a bit at T_mica=156 and Current in the Celani wire = 1.7 Amps. So we decided to run both wires so that we were running 1.7 amps through the Celani wire, but heating with both wires. We will see what this does to the loading (if anything). Then we will turn off the NiCr wire and see if it continues to absorb at that current and a lower temperature. We also saw that the impedance during that run was way lower than we currently have. Maybe it has to continue to absorb more. Or maybe those parts of the wire that didn't turn black again are not changing impedance as much.

I'd expect shiny wires to achieve higher temperatures than the dark ones (higher emissivity, lower temperature, same power)

Are dark (or darkened) wires performing better (higher temperatures on Glassout) than shiny ones in general?

A few questions:

- Is the 250-300 watts run mentioned yesterday (before an anomaly appeared) still planned if no apparent excess heat will show?
- Have you considered a short run at 7 bar to see if the wire can be loaded a bit more?
- Have you read my suggestion in this thread? > http://www.quantumheat.org/index.php/follow/150-attempted-wire-repair#comment-613 It would have been interesting to see if that actually had any effect while temperatures were stable.

EDIT: R/Ro in this run appears to have improved. In the very first runs too it was noted that cycling cooling->vacuum >loading appeared to improve R/Ro.This might be something worth to check out more in detail (also at the 7 bar I suggested?). Maybe there's an optimal number of cycles to maximize loading without wasting too much gas and too much time.

[however input power is also different from the previous run, so maybe they are not really comparable?]

It is a good thing that the wire appears to load again. I suggest that you just use heating of the NiCr wire for a long period since Celani was initially successful with this technique.

In my estimate, it most likely does not matter which wire carries the current as long as the active one reaches an adequate temperature. The gas will be at a relatively higher temperature when the heat is only from the inactive wire and this might be a major factor for heat production.

This is a fine experiment that you guys are conducting, keep up the good work.

could you load the hydrogen faster if it went through a ice bath to say make the h smaller and squeez in faster? just wondering
