Padua cell reheat/long term test [UPDATE #1 - Post run photos]

Written by Robert Greenyer on 29 July 2015.

After a herculean effort by me356 spanning 3 separate machines... the test has begun.

UPDATE #1 - Post run photos

So the long term run is over and after 5.5 days - with wonderful continuous quality live broadcasting of live data and flawless control - the cell cooled.

me356 should be congratulated for overseeing the longest non-Celani live run in our history and had this to say as he sent the pictures attached...

"It is great that Triac circuit worked that well and nothing really failed.

Today there was a moment, when I started the cooling process, but hot spot on the left side didn't changed temperature for long time as it was powered by something else. Everything including average of L decreased temperature by more than 100°C.

So there were really interesting phenomenons, but we can't still be sure what really happened.

Cell is maybe little bit bent, wire at the ends seems to be good. There are no cracks visible. So it looks like before the run."

@Charlie Tapp

The reactor is still charged and with me356 waiting for a break in my schedule.

The independent parties are funding GS2 and Parkhomov LiAlH4 + Ni analysis and conducting it on their own schedule.

At least one party has said that they will do the isotopic study tomorrow 18/8/2015.

@ Robert Greenberg just wondering why isotopic analysis takes so long ? What is the process?

@AlanG: I figured that me356 removed the outer alumina shells and inspected the heating coil before taking measurements. Maybe he hasn't yet, in retrospect.

Either way, that was more like an excuse to bring up that wire oxidation through heat cycles and other treatments could according to certain theories make Kanthal wires "active", just like Celani does with his Constantan ones, and as he reports having observed even with NiChrome ones.

I think it's more likely that the Kanthal wire partly melted on both sides. The molten metal would continue to conduct as we saw in one HUG test in Feb. When cooled, the metal would solidify and shrink, breaking or crystalising the conductive path.

@Robert Greenyer: interesting phenomenon nevertheless. I didn't know that the Kanthal wire's external Al2O3 layer could get so thick as to strongly hamper electrical conductivity at room temperature.

I'm wondering if this phenomenon could be taken advantage of for LENR experiments under low pressure hydrogen, as per Leif Holmlid's theories and observations. One could try growing/layerin g mixed metal-oxide surfaces on a thick wire a bit like Celani does for his wires.

Perhaps by checking out closely one could even find out that some iron atoms also migrated on the outside layer, forming iron oxide. In that case it wouldn't be too much different than Holmlid's catalyst material. It would lack an alkali metal, but that could be added during the oxidation process.

EDIT: see
jes.ecsdl.org/.../...
fy.chalmers.se/.../...
This seems to suggest it could happen if the oxidation phase is performed below a certain temperature. It would take a long time if done just by heating it, though.

Hi Glowfish

I did ask me356 but he said both were registering kohms - which is more likely that the oxide layer is very thick now. I will not get to look at it for a few weeks as in UK at the moment but this and establishing any off-set on the pressure sensor are the top of my list.

Can you check the overall resistance and the the "left" and "right" side coil resistances by measuring the coil from the center point to either end to see if there is any indication that parts of a coil were damaged or fused? The "left and "right" readings should add up to the total and should be fairly equal. If the readings are not equal then parts of the coil may have burnt out. it would be interesting to know as damaged coils would lead to asymmetric heating which may explain some temperature differences during the run.

@Robert Greenyer: what temperature sensor should be used for estimations?

GS2 calibration - basis for estimating any anomalies.
