No - I was suggesting that in previous experiments to this one - the same nichrome wire could have been used. Did they start out with a virgin wire for this experiment or not? Often experimenters cut corners and reuse items from previous runs.
I haven't asked but as far as I have seen I'm fairly certain that for the control cells they used completely fresh materials.
It is a common misunderstanding to think that all the hydrogen can be pumped out of nickel by vacuum or a combination of heat and vacuum - and the Hunt group simply may not have known how tightly the "last" proton is bound to 14 nickel atoms in a FCC crystal. The alloyed proton will not come out even at 2700 degree F. IOW you can load nickel with hydrogen up to a 1:1 ratio, but you cannot unload the last proton in the FCC crystal without melting it.
I don't think they are expecting to achieve *complete* hydrogen desorption; even Celani warned them that it's not an easy job at all to achieve that. It can be pumped out for the most part, but as you say there could be a remaining tiny amount virtually impossible to get out without destroying the wire.
Cheers, S.A.
