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 HUG lab has been busy all week.

The V1.3 cells in differential mode are waiting for a nice isothermal box to shield it from Ambient temperature differences that may have been creating falsely positive data.  The new boxes are fabricated and the controls and instrumentation are being put in place.  Then we will test them and see how well they hold a constant temperature inside.

 

 

The Helmholtz coils will be incorporated around the V 1.3 cells once the cells are in these boxes. That's the only way to know that we are seeing meaningful temperature differences.

 

The Multiwire test is at the top of the calibrated range on input power and running at very near the top of the intended temperature in the cell.  And it is just starting, at that temeprature (450+ C) to show a possibly meaningful excess power reading that seems to be increasing exponentially with the temperature.  We tried putting a water jacket around the outer shell to help cool it and allow it to run at higher temperatures, but our water bath was room temp and didn't enhance the cooling at all.  Cooling the water down to 15C does not seem to helping either.  We possibly need to get the wire up over 500, which in the glass cells with direct heating can happen easily.  

Meanwhile, Paul and Wes have been tuning up the three slightly different versions of the vacuum bottle calorimeters.  The third version totally enclosed in a 2 inch thick foam jacket is definitely the most stable.  

The job largely consists of tuning PID controls and testing the thermal response to minimize the control noise under different conditions.  Sometimes it isn't terribly straightforward.

 

On Thursday, a group of us went to visit St Cloud State University, which is the closest major university to us.  There is a theoretical physicist we chatted with and wonderful, integrated science and engineering facility that we toured.  They have the closest SEM to our location and it has a working EDS.  Hopefully we will be able to take advantage of it, now that we know it is there.

And, finally, a new experiment to rule out the Langmuir effect as a possible explanation for the higher temperature on the glass has caught out attention.  We will post more on that soon.

@ Ed Pell

It is not really controlled. It is just limited by the vacuum specifications. It is around 0.6-0.8 mbar currently.

Regarding the Langmuir experiment, there's a very useful paper on Glass-hydrogen catalysis, studied in detail at:

eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/24735/1/9%281%29_P42-54.pdf

A key experiment (described at pg. 50) demonstrated that trace amounts of water vapor will stop the catalysis, and removing the contamination by vacuum will quickly restore it. This has consequences for the cell calibration protocol.

@Ecco, I see your point about the vacuum.

@MFMP, how is the vacuum controlled in this experiment?

Really nifty update guys. It's fun coming back to see how steady the progress and evolution of the methods has been.
