"Bullstuff. A 'master zeroize' device isn't going to change the elemental composition and relative ratios of 'catalysts'. Blow it up with C4 and a good mass spectrometrer guy can XOR out the C4 and tell you what, and how much." Yes, but it "can" destroy any critical geometrical relationship (as in what precisely is the "nanostructure" of the nickel, how arranged in the reactor, and the like).
I agree with others that this is both (1) understandable as an effort (probably futile in the long run) to protect his trade secrets) and (2) also ticks up the 'baloney-meter' a bit. OTOH, he says it will only delay the 'non-industrial' application of his technology, so he's not letting his promise dates slip for the primary 1 MW demonstration which is key if the E-cat is for real.
On another site I saw that he has pinned down the 1 MW startup date to the last week in October. So it sounds like they have a pretty solid schedule in place (wish I could be that confident about project schedules in my own line of manufacturing!)
