Hydrogen Loading Commenced

on .

We just commenced loading of the Hydrogen into the Celani wire.  We are loading at 4.6 Bar and 170C.  We started at 3.5 bar H2 at room temp to be comparable to calibration runs with the Isotan wire in Helium, The Isotan in H2, and the just completed Celani Wire in He all starting at 3.5 Bar.

 

One early thing to note is that the resistance of the wire is dropping off quickly.  Cooool!

 

Interesting data from the Run #2 in He starting at 3.5 bar compared to the Calibration run 3 in He at 3.5 bar

The measured cell temperature is running noticeably higher with the Celani wire compared to the Isotan.  I haven't had time to do the same comparisons with the other temperature sensors.  Look for that soon.

Meanwhile, the impedance remains interesting with every run.  This time we see a dip in a similar place to the Isotan, but the overall slope remains positive.  Fascinating!

 

Thoughts?

Thanks Paul. I initially discounted such sharp voltage increments as I assumed you would be careful not to place unnecessary thermal shock on the Celani wire.

Quoting David Jones:
Perhaps I can answer my own question. Are the resistance measurement jumps due to the wire temperature being increased in two discrete steps?

If yes - my question is irrelevant.


The answer is yes. Those steps were manual adjustments to the voltage.

Perhaps another way of stating the problem of graph 1311 is that possibly, external electrical power equipment switching on or off are introducing errors into the resistance measurement at a magnitude comparable to the effect you are looking at.

A critical reviewer would not be happy with that.

In the top graph (resistance of wire verses time – Records 1311) you have instantaneous increases in resistance. This has to be an experimental artefact - to my mind anyway. Would you have any idea why this has occurred?

A critical reviewer of your experimentation would spot this anomaly and would want this cleared up - as the implication is there is an error/fault in your diagnostics.

Hi Peter, at this stage we are just working to replicate and extend Celani's work. There is much debate about the science - we need to first show incontrovertibl y that there is an effect.

Congrats very professional approach and execution!
Do you have a working hypothesis, WHY it works- if it works?
Wish you success, positive results beyond any doubt.

Quoting Valac :
Could you please clarify how the Impedance or Resistance are being measured?

If it was a DC resistance measurement (assuming current supplied from a Switch-mode converter) could you please publish the ripple current(s) spec for uncertainty calculation?

If it was an Impedance measurement (resultant of real component, reactive component and the theta angle), could you please publish the reactive component(s) of Celani's wire as compared to control wires, at fixed temperature, in air? and supply frequency? angle?


The mainstream critics will have to look into these.


The impedance is being measured at DC by measuring the ratio of voltage to current.. As such it has no phase angle and is the same as resistance.
I don't have ripple numbers handy but it is in the millivolt range, The A to D conversions are averaged for several seconds, mostly eliminating ripple.

Fascinating work gentlemen, thank you!

The impedance of Celani's wire continues to drop with the H2 loading.
We are now reaching 15.5 ohms, starting from 18.4 ohms.
R/R0 is almost 0.84 now.

By looking at the slope asymptote, we should be able to get the wire down to 15.0 ohms.
