I regret to report that I must retract the conclusions I reached in my paper, "Report on Mizuno’s adiabatic calorimetry." I uploaded a new version of the paper with an Appendix A explaining the reasons.
http://lenr-canr.org/acrobat/RothwellJreportonmi.pdf 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. I noted in the original version of the paper that ambient temperature was poorly controlled, and that problem needed to be addressed. I said that additional calibrations were needed before we could reach a firm conclusion. That is what calibrations are for. I was right about those two things, anyway. Some of the comments made in this forum were helpful to Mizuno and to me, prompting him to do some of the calibrations that revealed the problems. On one hand I feel embarrassed that I jumped the gun uploading the November version before calibrations were done. On the other hand uploading it helped speed up the process of finding the problems. - Jed
