I believe, like many, that the transmutations seen are surface side-effects of the LENR; and as Rossi now says, are not substantial contributors to the excess heat effect. I don't believe that the Cu that Kullander measured was contamination. My understanding was that the early e-cat reaction chambers were stainless and there is no reasonable way to produce that much Cu contamination within the stainless cell (Kullander said there was no Cu or Fe in the starting Ni powder). The fact that Rossi was previously adamant that the Cu was a transmutation product, probably means that he didn't add it as an ingredient. A case could be made that the Fe was contamination, but personally I believe the Fe was an additive since Rossi conveniently left out any comment on the greater percentage [than Cu] of Fe that Kullander found in the ash. This leaves the Cu as a thin surface transmutation by-product of the LENR. 10% surface transmutation does not sound like too much for a Ni ash of 6 supposed months of high rate LENR.
