First Results from HUG Concentric Tube Calorimeter
Starting on Friday, 19 April 2013, we started a hydrogen loading test on a 400 layer Celani wire in a new test cell and calorimeter. The treated Isotan 44 wire was provided to us by Celani a few months ago and kept in a polyethylene bag till it was installed in the test cell. We installed about 40 cm of the wire into the test cell.
View of the calorimeter as it operates on the workbench, today.

The goal of this test was to try out the calorimeter on a real test to verify that it works as intended. Due to limitations of the web site organization, we opted to consider this test just part of the commissioning of the calorimeter and not publish it ahead of time. We soon regretted that as interesting data started coming out. While we still could really use a web guru to help us organize the site for multiple experiments, we decided to share this data and get many more minds working on it ASAP. Unfortunately, the live data stream will be a little slower coming since we haven’t figured out if we want to share the internal test setup or move that calorimeter to a different computer. This document is intended to publish the data and invite others to examine the data, the analysis, and the conclusions, and add interpretation.
The most interesting result is that the wire loads rapidly once at the right temperature and seems to achieve a ratio of H/Ni atoms of 1.16:1, which should be close to a complete loading. Another interesting find is that the resistance of the wire didn't start to change much till the majority of the loading was complete. To the best of our knowledge, this is the first time these characteristics of a Celani wire have been observed. We are hopeful that this data will be useful to others trying to understand this line of experiments. We also plan on designing future tests to get cleaner data.
Donations of web support (specifically Joomla and PHP), and cash donations are greatly appreciated to help bring this out to the world. Additionally, we are hopeful that we can refine the calorimeter into a version that could be made available for interested research partners.

3. Wire diameter is stated in patent item 033 as 200 um. (0.2 mm). This is consistent with previous descriptions in MFMP blogs. The surface area of the 40 cm long wire in the CC test cell is 2.51E-04 m2 and the wire would therefore contain at least 5 mg of oxygen. This is 3.14E-04 mole of atomic oxygen
4. According to the MFMP molar calculations 6.92E-04 of H2 was lost during the initial loading phase. Therefore, it seems likely that nearly half of the hydrogen and possibly all of it went into reduction of the oxides in the wire coating, producing H2O. This is not loading in the LENR sense, and would not represent absorbtion of hydrogen into the metallic lattice, which is what we are interested in.
1. Item 20 on page 1 states the oxygen content bound to the wire to be "not less than .05 g/m2" This appears to apply to a single layer. IF the layers are thin, concentric and chemically similar, a 400 layer wire would then contain at least 20 g/m2 of oxygen bound to the wire by the process described.
2. The process described in the patent to create the layers uses both NiNO3 and PdNO3 in solution as well as SiO2 as a binder vehicle. The final composition of the layers may therefore contain oxides of both Nickel and Palladium as well as residual silica. Subsequent reduction by H2 will not react equally with these constituents and the binding / dissociation energies should be looked at further. For now, assume H2 fully reduces each of the possible constituents mentioned in the patent.
We have not seen any indication of excess heat coming out of the cell since the report period, but we did see a tiny amount more hydrogen pressure drop. The last 3 days have seen no appreciable pressure drop, though.
And we are working on making it stream the data live to the web ASAP.
Absolutely. Consistency and reliability of results are much more valuable than unreliable "positive" results. You need to know what you're doing to understand what you've done.

That's exactly the document I read, but to me the end results looked overall disappointing. There surely are other kinds of anomaly probably worth to look into, but the 'main dish' so far has always been the prospect of measurable, significant excess heat as a smoking gun for LENR and to me it seems that this goal is slowly fading away.
@ Ryan Hunt
What I was saying is that although the intended focus of this experiment might have been different, it should also be useful for excess heat measurements. Even though under dynamically changing conditions, the wire should have already loaded for a few days.
Data from his ICCF17 presentation showed that Celani was already reportedly getting significant excess after just a couple days of loading, at an increasing trend.
Loading Hydrogen into an 'active' Celani wire...

I might be missing something, but I see:
- an 'active' wire is being loaded in Hydrogen in a tube calorimeter
- temperature data is being compared with that of a previous run with an inert wire
- that direct heating is being applied
In which way this qualifies as a test? It seems similar in principle to previous experiments performed so far.
The 'other conclusions' in the document (which are the main conclusions? It's not clear, although I've only quickly skimmed through he document twice) also seem to pass over the lack of excess heat seen so far.
Unrelated to the report, but speaking of this page, on Chromium browser under Linux pressing the left and right keyboard keys in this message box causes some problems with the scrollable photo slideshow immediately above it.
