It can only slow it down. Since the outer surface was nearly as hot as the inside, this insulation hardly delayed it at all.

No, it would not. See: http://lenr-canr.org/RossiData/Houkes%20Oct%206%20Calculation%20of%20influence%20of%20Tin%20on%20Tout.xlsx Unless you can show a problem here, Houkes wins this debate. Anyway, as I pointed out, two different methods were used to measure the heat output, and they were in reasonable agreement, so there is no large problem with the thermocouples. > But again, we could know and we don't > because Rossi won't allow the proper testing method that would clearly > tell us about all such potential errors (and more). > His methods clearly tell us about all potential errors, by first principle analysis. Granted, not with much precision. - Jed
