If Rossi was using corundum, then carborundum would seem
like an improvement, but it is important to track down the actual
composition of what was used in the December test.
I asked about this while correcting typos in the paper. One
of the authors told me it was "corundum, corindone in Italian."
Thanks - it is a bit of a surprise. It is true that the fluted cylinder with
the slots - which holds the resistance wire could easily be corundum which
is light-colored. Carborundum is blacker than black.This picture on Alan's site shows the proper coloration of corundum http://lenr.qumbu.com/web_hotcat_pics/130531_penon_07A.png But this picture, below it - shows a black cylinder inside the HotCat where another separate cylinder should be, and it is not light colored and not stainless. http://lenr.qumbu.com/web_hotcat_pics/130531_penon_08A.png Therefore I am still of the opinion - but without any real evidence other than this picture, that the ceramic which holds the stainless steel capsule is carborundum or SiC.
