And your point is simply wrong. See my discussion of crafts guilds. They reproduced a great may and greatly complex items with no written instructions or theory of any sort.
What you are doing is confusing scientific reproducibility with engineering repeatibility (to use the specific terms correctly). What Rossi has apparently gotten is engineering repeatibility (that is, he can reproduce multiple items that work the same way), even if other groups without his "recipe" cannot. This is perfectly sufficient to have units to sell. And is legitimately done in all industries under the guise of "trade secrets".
It is one thing to not be able to reproduce the performance of a device without the trade secret, it is another to not be able to reproduce it at all.
It was interesting to hear someone talk about the problems with what is proposed. Like the lack of any theoretical way for these materials to undergo a transmutation and that the copper that was in the sample was naturally occurring and the lack of radiation. That all from someone isn’t declaring it a scam..that Rossi has used to boost his prestige.
