following the quote that Mats lewan mad in his book on pauli and semiconductors, "One shouldn't work on semiconductors, that is a filthy mess; who knows if they really exist!" I fall on that evident quote of pauli http://blog.disorderedmatter.eu/2009/03/16/wolfgang-pauli-speaking/ "God created the solids, the devil their surfaces. (Pauli)" I think that for LENR it should be adapted as probably the NAE is not even the surface, but something more diabolic (vacancies, defects). It seems science did not advance much since the 1920s, about maturity.
