Much has been going on in Minnesota and with everyone else busy, we are trying to find ways of getting more information to you all faster.
Two cells are being constructed into isothermal boxes for testing the array of nano and nano-micrometric powders of various types we have access to from Brian Ahern, QSI and Bob Higgins.
The development work has been captured into Evernote as this is really convenient to do for the team - in this case Malachi and Ryan - however, Alan Goldwater and Mathieu are starting to use it also, so we had to find a way of getting this information streamed onto the QuantumHeat.org site. We have been testing Zapier.com and cloudhq.net and are using both - one is making PDFs of posts and the other is making links to the Evernotes in a Google sheet.
Let us know what you think.
UPDATE #1 - Cool videos
Disassembling the powder cell
Swapping the micro Ni powder for the Quantum Sphere Inc nano Ni.
UPDATE #2 - Brian Ahern powder IN!
After a VERY generous donation of time, money and resources by Nikita Alexandrov of Permanetix Corporation, Last week, we received back the milled Zirconium Oxide / Palladium / Nickel matrix powder to the milling specification of Dr. Brian S. Ahern. A big thank you to Nikita.
About a third of this powder was today, 15th August, placed into the powder cell. A further third or so is expected to go into the "Sparky Cell" that another great volunteer - Skip has been working so hard on of late.
Check out the recent links to Evernote above for the details.
Keep watching this space!
UPDATE #3 - Loading!
UPDATE #4 - Calculated excess rising?
Calculated excess heat above calibration consistently trending upwards as Dr Brian Ahern's powder continues to absorb Hydrogen.
Ryan has made a live google spreadsheet that regularly updates showing calibration based calculations of excess heat.

UPDATE #5 - Testing Higgins' Powder, Dec 15, 2014
Powder from Bob Higgins has been installed into the cell and the cell calibration has been checked. The calibration was right on from last time, still. Nice. What happens next? Bob Higgins suggested this:

Notice the pressure...!
Ryan, that is exactly what caught my attention. T_well is running 0.5C hotter then RTD_hot. Could this be calibration error? If not, there's something worth a closer look!
Here's another snapshot.
A t_diff of 0.2C isn't very much, but that's just through the thickness of the cell wall.
Where is the heat coming from? Apparently from the cell core, because RTD_hot is consistently about 0.5 degree below t_well. Ambient temp variation seems to have a small effect on RTD_cold, suggesting that the heat flow is minimal by conduction through the cell stem. Yet the calculated excess power doesn't seem consistent with the inside of the cell being hotter than the outside.
The vacuum pump has failed again badly and so the experiment is effectively down at the moment. We will look at solutions to resolve this.
Interesting to see what this will do to the performance of the powder now that it seems to have passed for the time being.
More basically speaking, my idea was that if water is getting formed as hypothesized, perhaps the zirconium oxide in the powder could have something to do with that as I doubt there is still any humidity from previous ambient exposure left in the powder. Consequently, if water is getting formed it is also probably conceivable that free O2 is as well, for example through catalytic water splitting processes exhibited by similar nanomaterials in other LENR studies.
That is an interesting hypothesis. The bond strength of ZrO2 is very high, 760 kJ/mol according to
web.chem.ucsb.edu/~zakariangroup/11---bonddissociationenergy.pdf
But an article at pubs.rsc.org/en/Content/ArticleLanding/2002/CP/b109887j#!divAbstract suggests there is some reduction of surface defect sites at lower energy.
Finally, the abstract at nature.com/.../1911192a0.html states that no bulk reduction is seen up to 2500C and 150 Bar H2. At higher temps there's a hint that reduction by atomic hydrogen is possible.
I'm starting to wonder if heating the cell under pressurized H2 atmosphere isn't slowly stripping away oxygen from the active powder's zirconium oxide, forming trace amounts of water and gaseous O2 in the process. This could explain what you're seeing with temperature oscillations (due to water vapor randomly affecting the heat flow) and perhaps even what Dr.Ahern observed, including random violent explosive events (once O2 concentration inside the cell gets high enough to form an explosive mixture).
Lenka, Ryan and myself had a lengthy debate about that today. We agreed that lowing the pressure delivery would make it very difficult to know the loading ratio, for now it was decided to let it run and focus on other cells, ones that may be engineered to remove any chance of convection effects that we suspect may be going on at the top of this cell.
The experiment is producing good data the we feel we can learn from.
