The holiday break slow us a little here in Lausanne.
We opened the cell just before Christmas and Mathieu took the Celani wire that was used for the December runs back in France for EDS spectrometry analysis.
One of the threaded rod maintaining the cell sealed was damaged. We ordered new ones, but hardware shops were closed in Switzerland during the holiday break. This delay allow me to do small upgrades:
- new stainless steel nuts and bolts to hold the wires
- triple braided nichrome wire to have a resistivity closer to the Celani constant wire
- additional Glass_out thermocouple covered with copper tape
The cell has been reassembled now with the latest generation of Celani wire, codename: 2L
We performed a leakage test under 2.5 bar of helium with 20W in the nichrome wire. Everything looks good.
Some details of the new thermocouple installation with thermal silver paste and copper tape.
Closeup on the braided nichrome wire and the new nuts and bolts fixing the wire.
We will start with helium calibration today. However, we will not have time to do extensive calibration as we will go to Germany with the cell next week to show it to a potential partner.

I just analyzed the 49 Watt step and the calculated power input is very much in line with that of earlier today. My program suggests that the power is 47.04 watts input versus the actual that is approximately 48.9.
The time domain behavior is stable and matches the calculated curve so all is well.
I will review the data that I used for the calibration and see why the small error hangs around.
My work is with cell 1.0 for this information.
As the power slowly falls off from 49 watts to 48.8 watts it is very easy to observe on my chart.
I turned on the air flow inside the vent hood.
I thought it could average the ambient temperature by mixing the air around the cell.
It was actually a bad idea and it is amplifying the oscillation of the room temperature control.
I will turn the air flow off asap.
A quick run of my program suggests that the NiCr inactive wire is now reading approximately -1.9 watts as compared to the original calibration.
The Celani wire reads -2.3 watts under similar conditions.
The amount of data that I had to analyze is very limited at the exact switch point, so noise is affecting the readings somewhat.
The best conclusion I can reach in this case is that the Celani wire allows .4 watts less power to be registered at the glass outside.
I will post the calibration data to this message soon.
Beautiful work on the braiding!

The best way to help is to get involved with one of the Collaborate mini projects or donate directly to the project, that lab in Lausanne is expensive to rent! Next week we will have a series of mini projects to allow people to help with localising (translating) the sites main pages so that the MFMP is more accesible to more countries. If you could help with the German translations that would be really helpful.
We are planning to have rewards on the Kickstarter that will be imminently launched (just finalising the legal + Video) that will allow people to visit an experiment site, but we will need some background checks - I hope you understand.

The room is environmentally controlled but it has an AC cycle signature, Nicolas has bought a fast response heater and has a controller there and will employ it if it is deemed necessary. We have to be aware that in many LENR experiments, temperature and pressure variations can be the thing that triggers the effect so a very stable setup may be less likely to show an effect.
Would like to aid in some ways.
