Hundreds of them stood up to scrutiny in the literal sense, "a close and searching look." That is to say, you could see the cells were boiling. After a while there was no more liquid between the anode and cathode, so there was no electrical current. Blank cells driven to high power immediately stop boiling when this happens, yet these cells not only continued to boil, they remained hot to the touch for hours.
@Jed. It is obvious that a few blog posts cannot settle this disagreement easily. However I do notice when someone makes comments which are internally innaccurate. In your case your point only stands if there are no chemical sources of heat present after death in the active cells and not in the control. Yet, this is exactly what Kirk claims and has proposed a mechanism for.
I realise you don't view his claims as likely. But you cannot use this argument, as stated, as additional ammunition against them because if they are true it falls.
On a more general point I view this type of anecdotal evidence with suspicion. If definitive it could now be replicated, with careful instrumentation, and would be the clear evidence Abd et al want once chemical causes had been eliminated.
