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 US team has begun the loading phase in Cell A.  We just loaded 3 Bar of H2 into the cell and turned the power on to 30 Watts.  It will stay that way for a day or so while the initial absorption happens.  Then we'll refresh the H2 and cycle it 6 hours on, 1 hour off.  We are excited to see if our wire can achieve a similar (or better) resistance change compared to Mathieu's.  The race is on and it's down to the wires!

 

UPDATE 21-06-13 - More troubles than I can shake a stick at

The US cell's loading has been plagued by several minor difficulties that make the data less than attractive to look at.  First, we hadn't turned up the power on the active wire far enough to get a clean baseline resistance reading. Then the temperature with the hydrogen in the cell only barely got into the loading range.  Then when went to turn it up, we found we had to adjust our max power limit (a hardware circuit we had installed after the last time we toasted a wire).  When we adjusted that, we bumped a ground wire on the power meter, causing the reading to go wile and the power output on the NiCr wire to go to max.  In that process, our output port controlling the Celani wire power was toasted, and we had to move that to a different output pin, reconfigure the software, and reload.  After that, over lunch we had a power blink, which reset the power outputs.  Then we found that the second tier software power limit was getting in the way of achieving full power on NiCr wire and had to reset that.  Finally, we thought we had it all going and then one of the instrumentation boards started blinking out every so often and dragging the other one down with it.  When they reset, the power outputs reset also, and the cell cools down.  We are still troubleshooting that one. -- Update-- That was found to be a power wire issue caused by the data acquisition boards being powered from different sources.  Paul and Malachi found it by watching the power chip on the board heating from 40C to 150C before it blinked out.  Turns out it has been wired poorly for 8 months and has worked ok till now.  Pretty resilient boards.

That is all pretty crazy for a system that has basically been up and operating for a couple months as we troubleshot the ambient environment and performed the calibrations.

While the data is not the cleanest, we are definitely seeing a drop in resistance from roughly 16.2 to 15.1, or so.  Not as big a change as Mathieu saw.  

The next step is to begin the cycling (35W, 3 bar H2, 6 hours on, 1 hour off) for most of the weekend.  Since Mathieu has other obligations for the weekend, we should be caught up on Monday and ready to move forward nearly simultaneously.

Here are some pictures from today:

A photo of the wires in the cell.  The Celani wire is looking very light and coppery colored. The NiCr wire is looking almost blue-grey.

UPDATE #2 SEM Pics now in Ignite Gallery

After some much-needed (and time-consuming) maintenance, our SEM was available for a closer look at what we're testing on in the US1.3 experiment. How timely!

Head over to the Celani V1.3 production gallery to get a glance. 

There're also pictures of the metamorphology produced by adding acetone to the CTC Celani wire in the gallery of all things related to the hydrocarbon anomaly we've been experiencing. 

 

Notice how poor our resolution is? I did a LOT of doctoring to amp-up the contrast and clarity of the resulting images. We are in desperately short supply of an experienced SEM technician since we lost ours to a walkabout in Australia Wink. It seems nano-fine tuning of a 20-year-old JEOL SEM is more of an art than the technical manual lets on. If you or someone you know could be of any help in working with an SEM, drop us a line! We're exceedingly good at utilizing remote instruction and could really use the remaining 295,000X resolution this machine is capable of. It's quite dated but that's no excuse for the limits we're experiencing.

The T_Amb sensor didn't seem to show such pattern, however.

@ecco - I believe that would be real room ambient cycling causing that signature. The CTC ambient is in the open air in the same room and would be a good source to refer to. Our air conditioning has not proved effective enough.

Whatever it's causing this, it's affecting US Cell A slightly more than US cell B.

Longer term data shows the huge improvement in loading after applying more power in US Cell A.



It also shows something very interesting (see red arrow). For some reason external temperature has increased a bit, even though pressure is decreasing and convection toward the glass tube should be decreasing. Furthermore, it doesn't seem this increase is correlated with changes in the data I can see.

Could this show excess heat generation as the wire gets loaded more deeply? Or is it just an artifact (it's a very small change after all) due to something else?

Wearing back my skeptical hat, have there been changes in wire appearance/colo r or apparent glass tube transparency in the past hours?

EDIT: the control cell unfortunately is currently not powered, but its ext.temps seem to show a similar pattern. So maybe it's an artifact. Or somehow one cell is affecting the other one.

This is great data we now know you need to be hot enough to load at a reasonable rate. I suggest in future you add a temp sensitive wire as a third wire winding so we know the temperature of the wire.

A day later... Wow that is beautiful. Looks like temp cycling is not needed.

After the 45W step is done (in about 15 minutes as of writing), cool, measure cold active wire resistance, then 50W passive heating? Seeing how the more heat is applied, the more loading rate appears to increase, it would be very tempting to do so.

If what I've written above is true, it implies that we want really hot hydrogen inside the cell. Therefore, by taking this concept further, ionized hydrogen. Also, we want the ionized H2 to come in contact as much as possible with the active wire.

Does this ring any bell?
It does to me!

BTW: US Cell A with 44W of heating power is currently behaving as I previously written. 45W will improve loading further.

Another explanation could be that when you increased power to 45W, the active wire immediately received irradiated heat from the passive wire, which caused an immediate increase of its resistance as a result, maybe improving hydrogen loading marginally.
Then, as time passed, hydrogen started getting heated too, which improved absorption in the active wire noticeably.

If this makes sense to you, perhaps it would be useful to heat the hydrogen atmosphere more efficiently rather than the wire itself, for example by keeping the gas actively moving around inside the cell. Things could get really interesting.

Just a hunch.

@Ryan Hunt: the wire increases its resistance when it gets hotter. However the higher the temperature, the better hydrogen gets absorbed.

From all experiments seen so far, it looks that wires respond faster to heat than hydrogen absorption.

What I think happened is that when you increased power all at once, wire resistance increased noticeably, but chances are that if you had let it run, after a certain time/threshold you would have seen resistance decreasing in a way similar to when you load a new Celani wire for the first time.

By the way, would it harm the cells if you temporarily disabled forced air cooling, to increase temperatures without increasing input power?

@ Ecco - in previous temperature stepping we have seen that there are optimal temperatures for causing the resistance drop. When we went too high, the resistance increased.
