Quirky data in H2 Splitting Cell

on .

From Ryan Hunt:

After a couple months of near zero blog entries from the HUG labs, it probably seemed like we weren't doing any experiments.  ... And, we weren't.  We shifted our focus for a while on building some domestic water reprocessing equipment for Paul's house.  But, we took advantage of a lull in that project this week, and fired up the H2 Splitting cell.  This morning we noticed a fairly regular tick in the resistance, the temperatures, and the pressures.  Check it out below:



Data available at: data.hugnetlab.com under test FC0408 - LENR Cam: Hydrogen Splitting

Full lab notes in our Evernote lab notebook.

The key feature is a very stable, periodic tick where the resistance rises, the wire temp rises and the pressure rises, while the thermocouples wrapped in platinum and silver both fall.

Over the last 3 days, the oscillations have stopped for a while and then restarted.  The pressure, though, is more noisy when the oscillations in the temperature are not present.  

Meanwhile, there is minor oscillation in the resistance that looks like a sawtooth wave if you zoom in close during the early part of this test where the resistance is generally falling.


We are not sure what to make of all this.  What is going on in there?  Eyeballs and ideas would be welcome on this mystery.

Ecco, we have been completely ignoring it while we work on the new powder cells. We were in that room, so we might have inadvertently affected it, but we did nothing intentional or noticeable to it.
We still have the possibility of writing a script to time sample the gamma file, but other than that long shot, we ran out of ideas about how to test to see if it was something convection related vs something else.

@MFMP: yesterday at about 16:45 UTC the oscillating pattern greatly decreased in amplitude and stopped completely at 21:15 UTC. Did you find the cause for that in the end or did it change behavior by itself?

Due to the usual problems with the Evernote app stopping receiving notebook updates after a while and fooling me into thinking that nothing was going on, I switched to the clunky Evernote web interface.

I see you're currently attempting a 1W step down experiment. Interestingly, it seems that temperatures are getting noisier as power gets decreased. I would have expected the opposite happening.

It's still hard to figure out what's going on exactly, though. I didn't initially realize there's a cooling water jacket in this cell, so it might be an idea to switch it off and empty it completely from water for a few hours to make sure it's not causing side effects (since temporarily stopping the water flow alone seems to affect significantly cell behavior as you tested yesterday).

I just came to realize that the weird spikes in active wire resistance are so tiny that the power supply is barely reacting to them, if even at all, to keep input power constant.

On the other hand, such tiny changes are causing internal temperature sensors to apparently react significantly, although I understand that temperature alone can't tell the entire story.

I tried plotting a short section using "history" 1 Hz data:


Top chart: Cu (red), Pt (green) temperature
Middle: Active wire temperature
Bottom: Active wire resistance

The vertical red lines are aligned to peaks in active wire temperature.

Fixed the evernote image.

I see a related update in the Evernote logbook, but the attached image isn't loading either from the Evernote web interface or from the official application.

@ All

I did some more playing with the cell this morning. I detached the power supply from the cell and used a power resistor to test our control software. It works fine on a resistor. We may have a loose connection or short somewhere in the cell.

Currently the cell is not powered and we will decide what to do.

We are going to open up the cell to rule out any shorts or loose connections. The test will not be collecting while the cell is unhooked.

It appears that the cell has 3 modes it has operated under during the last week. The write up is int he lab notebook entry for today.

@ all

I changed a control parameter and reset the controller board. I will allow the cell to cool and then I will turn it back to 46 watts. I notice that the power was controlling poorly before and that is what prompted me to look into the settings, where I found a small issue.

@ Ecco

They should be now every 1-2 seconds. I found that the system was trying to read a board that was no longer attached, that was slowing everything down.

@Malachi: thanks, it looks like high resolution data points are slowly coming in; still not quite every second, though.

@ Alan G

Nothing was done to the cell over the weekend. We are going to let it cool and heat it back up to see if the oscillations come back. Then we can vary the input power up and down to see if there is an "activating" temperature.

Since we allowed the cell to go dormant last year, we have done nothing to the cell. The first thing I did when we started it back up was to vacuum the cell and put hydrogen inside. Then I applied 46 watts. The cell had not been moved at all. Though it was allowed to get very cold at one point (we turned the heaters off in the lab).

Also, Ecco, I changed the data interval to 1 second instead of 5 seconds. We were getting history at 10 second intervals for this test. Now it is at it's max pull. Sadly we won't be able to see the past weeks worth of data on this interval, just the future data.

It looks like there is an inverse correlation between T_Board (ambient temperature?) and Active Wire resistance:


This could imply that the strange repeating signals/cell behavior were due to a hardware fault somewhere.
+1 #14 AlanG 2014-03-16 16:38
Looking at the current data (16MAR2014 14:21:36) the oscillation in the active wire resistance is still visible, but the corresponding blips in T-Cu and T-Pt are gone. T-Wire is also flat.

Were any physical changes made to the system?

point [0011]:

It's possible that monoatomic hydrogen is a pre-condition for "ultradense hydrogen"



Francesco Celani says that a prolonged permanence in air may damage his wires, while keeping them in hydrogen atmosphere for long time may be useful.

This is the only official source I could readily find. There are video lectures on Youtube and Powerpoint slides available elsewhere but I don't remember reading very detailed descriptions about these devices.

What I am aware of is that NANORs use "pre-loaded" active materials. They do contain deuterium, but not in gaseous form. This is how they look like: e-catworld.com/.../...
+1 #11 Giorgio 2014-03-15 15:50
Where can I find a detailed description of NANOR ?
Are you sure that it does not use hydrogen or deuterium ?
+1 #10 Ecco 2014-03-15 15:41
@Giorgio: what about non-gaseous, "solid-state" systems, like Swartz's NANOR? If it does work, it implies that active catalytic hydrogen/deuter ium splitting is not actually needed for LENR to occur. It would be more like a trigger to achieve the proper conditions for it.

" might have a positive energy balance?"
I don't know, but prof. Sergio Focardi clearly stated the importance of H2 splitting in the E-cat reactor:


"Attraverso il catalizzatore l’idrogeno si trasforma da molecolare ad atomico..."
"Could long-term exposure to H2 be the key?"
I'll forward the question to Francesco Celani
+1 #8 Ecco 2014-03-15 13:40
@Giorgio: do you think the entire process in this specific case, assuming no artifact is occurring (which might not be the case), might have a positive energy balance? If yes, then the cell's exterior surface should also be slightly hotter than normal for the given input power. It's a bummer that it's not being monitored, although I understand that assessing the cell's thermal output wasn't the original purpose of this experiment.

The only question would be why is it acting like this way only now? Could long-term exposure to H2 be the key?
