But he is still giving the most credit to Piantelli, when probably that is completely wrong, and the three things which led to this breakthrough were (in order of importance): 1) The previous Rossi/Leonardo TEG work with nano-nickel 2) The published work of Randell Mills 3) The published work of Arata/Zhang, Kitamura, etc Obviously when you are a smart guy like Rossi, you find an anomaly in one field (thermoelectrics) with the same Raney nickel you had discovered as being so energetic that it caused two fires in you Lab . and then, as any good experimenter will do - you go to the internet to look for help or understanding in unrelated fields, then 2) and 3) above are the most authoritative help out there. Next, you apply what you have learned to a field that became bifurcated in the mid 1990s, due to ego problems, and WOW, suddenly you become the hero of that unrelated field. IOW - Rossi had his "Goodyear moment" at the expense of all of those in LENR, including Piantelli, who refused to acknowledge the gigantic advance of Mills, who himself was too egotistical to want to believe that he got a major part of CQM wrong - and that in the end the secret was nothing more or less than a subset of the "cold fusion" field that he dreaded so much. A short and fractured (fractal?) history of LENR in a brief reappraisal. Jones
