Lugano resistance drop re-visited
Could the drop in apparent resistance of the reactor heater element in the Lugano report be in part due to the core ceramic conducting at high temperature and partial shorting between the 3 phases?
There have been burn outs, core breaches, melted heater wire, hot spots and arcing thermocouples over the months.
Alan Goldwater deduced there was a drop in resistance in the ultra pure Al203 Coorstek cores we were using.

Additionally, SiO2 based ceramics resulted in plain shorts causing loss of thermocouples.
More recently, Adriano Bassignana made us aware of the Nernst Lamp

Of course, most replicators reactors to date have been single phase. So the differential between two adjacent coil loops where ceramic conductivity has increased would be lower than that between a parallel, helically wound, 3 phase coil.

Closing the loop would do it too. i.e. all control and stimulation power harnessed from output to run reactor for beyond chemical possibility.
This is the kind of Discussion that Bob Higgins and I had.
This and the wrong use of Emissivity means that for me, it all comes down to seeing statistically significant transmutations.
You will not perhaps think this relevant but:
3 phase makes it very easy to get an apparent COP=3 for free by inverting one of the input clamps on the power meter.
Without a proper power meter 3 phase makes input power measurement problematic.
The complexity makes errors in input power measurement, whether unintentional or deliberate, much more possible.

"I had tried heating mullite pipe with torch back in May. Becomes very conductive before melting. 1 cm gap was about 100 ohms."
Given that there was barely more than a few millimetres between phases in the Lugano reactor, and a large potential difference between them, this effect cannot be dismissed easily.
Which I don't mind, but it does make discussion there less informed than one would wish.
