Did the *GlowStick* GS3 see excess heat? [UPDATE#1 - significant discovery affecting replications]

Alan analysed the data from the calibration, active and subsequent re-heat runs and whilst it appears at that some of the observed departure from calibration can be explained by wire binding and movement - not all can be see below.

Jack Cole commented on the experiment also compared the family of GS3 charts produced by followers Sanjeev, Ged and Ecco during the GS3 run with his own data, see this graph clip

that had a similar behaviour to one of his own experiments that he suspected of producing excess heat.

"Here is a chart from an experiment I did that showed apparent excess heat."

Notice the similarities...

He went on to say "The declining and increasing power above the Parkhomov zone make it less likely that moved or constricted coils are the explanation. The coil would have to be shifting about to create an effect like that."

It is too premature to call anything, a post tear-down calibration may help, the real clincher would be evidence of elemental or isotopic ratio changes in the ash. Here is what the plan is in that direction in Alan's own words:

"I'll be opening the GS3 reactor on Monday after checking the residual pressure. Then I'll pump it down to vacuum and leave it for a while to de-load the hydrogen. After reinstalling the core thermocouple I'll do a final calibration run. These steps will be done with the reactor in place on the test stand, without disturbing the thermocouples or heater coil.

As a final step I'll remove the fuel and divide it into samples for isotopic analysis."

Whatever the outcome, we have to thank Alan and Skip for a job very well done.

UPDATE#1 - significant discovery affecting replications

Further study of *GlowStick* GS3 reveals important finding that all replicators need to consider.

Over the past few weeks, Alan Goldwater has conducted a study with the GS3 cell following observation of some strange behaviour of the in-cell K-type thermocouple in the post run book-end calibrations.

We have been discussing it for some time and Alan has now produced a report summarising the findings.

Thanks again to Alan for some excellent research.

This has implications for choice of materials, failure modes of heaters where thermocouples are in proximity and also for potential stimulation through the reactor body and fuel - perhaps that may explain one of the reasons for 3 phase - large differentials between coils.

Anyhow we would be interested on your thoughts.
