I was noting the FIRST PARAGRAPH (and Appendix A)
Some calibrations performed after this paper was written cast doubt upon the results. I now believe that most if not all of the apparent excess heat was caused by changes in ambient temperature. This is described in Appendix A.
During initial & final tests (see jccf 15 paper for details) for the Mizuno experiment the input energy of the circulation pump was measured and taken into account. The pump was always hotter than the environment. (Ambient) In fact it looks like the pump itself heated the environment.
For me two questions remain. How can Rothwell be sure that the pump he has seen months later behaved as before?
Why did Mizuno not test the PdZrNi powder which reacts 10 times stronger?
My only guess: Mizuno sole wanted to aquire knowlege - the so called Rossi-Enterpreneur-Effect.
