Another day, another calibration

From Malachi, LENR Engineer Extraordinaire:

We are now through calibration #5 and currently working on calibration #6.  We accomplished 8 runs so far and there are only 4 left!

We found a leak in the heating wire pass-through on saturday.  We had lost a few tenths of a bar over the calibration cycle.  I spent a few hours in the morning taking the reactor apart, fixing the leak and then reassembling it. 

 We decided to put another layer of the high temperature epoxy over the passthrough and it seemed to work once loaded with hydrogen (no leak detected with the combustible gas detector).  

After the next calibration cycle there was a small leak in the same spot.  We believe that the temperature cycling is causing the epoxy to "crack" or become detached inside the pass-through. 

We continued with our calibrations as normal, making sure to renew the gas mixture before each calibration cycle.

After extracting the useful data of each calibration we noticed interesting behavior in the impedance of the Isotan 44 wire when current runs through it.  We will be posting the calibration data, in and xls file with a few graphs as well as the raw numbers in a csv file, for those who are interested in taking a look.

Results for each Calibration run:

• Raw Data - Comma delimited data file (CSV)

• Spread Sheet - in a .xls format

• Graph of T_Mica & Power vs time

• Graph of T_Mica rise, T_Well rise, T_Glassin rise, T_Glassout rise vs Power

• (rise denotes temps - ambient air temp

• Graph of T_mica vs power with 2nd order polynomial curve fit

• Graph of Isotan (Red Channel)  Isotan impedance vs T_mica at equilibrium

• Report with notes, times, people involved, polynomial fit, and any other observations

From Ryan:
Feel free to peruse this data.  It is so new to us we have only done the earliest of analysis of it.  I am interested at looking closer at the runs with the Isotan in hydrogen and looking for evidence of small energy gain as soon as we get a chance.  And developing correlations between temperatures achieved in hydrogen and helium.


New Flanges for Pyrex Glass
In order to be able to more closely replicate the original experiment that Celani did, we bought borosilicate tubes.  Unfortunately, I bough a thicker wall for strength and found they didn't fit so well in the existing flange grooves.  So Wayne, our Mechanical Wizard (yes, that is his official job title) is busy making a couple new sets of flanges.  I am not willing to interrupt the on going calibrations to re-machine the original flanges, so we are building up a new set. Depending on what we learn about the leaking passthroughs, we might have to build a whole new test cell that may include macor ceramic wire supports and a more robust wire pass through design.

Two new features on this flange:  wider groove to accommodate a 3.2 mm wall on the borosilicate tube and 3 additional 6mm threaded holes to allow the glass and flange assemble to stay intact while opening the chamber.

On Friday and Saturday we were fortunate enough to have a visit from Tyler Van Houwelingen, another QuantumHeat team member.  Unfortunately, I was so absorbed I didn't snap any stills and I haven't pulled any stills out of the video footage.  He enjoyed seeing our facility and the progress.  Then we had a conference call with some of the European team members and brainstormed about issues going forward.  More on that later when we get a video edited.
