/* Are you adding the Mössbauer resonance to the recipe? */
IMO the cold fusion is the result of synergy of many effects: from purely mechanical to quantum ones. But the low-dimensional collisions are dominant cause (they're presented at most LENRs, from low energy over LeClair's to Holmlid's one), the quantum tunneling and orbital resonance are second effect and the electron shielding third one. We cannot explain the LENR once we omit two or more effects from the whole picture. The Mössbauer resonance is sorta weak Astroblaster effect, when low number of atoms are involved, but the principle remains the same (the conservation of momentum during multiparticle lattice collisions).
/* 80[keV] are not 2[MeV] */
The ionization energies of last electrons inside the large atoms get even higher, than 80 keV

In essence it's easier to strip the nucleons from large atom nuclei, than to remove all electrons from them, which renders the atom as an energetic continuum rather than separated layers from this perspective... Please note, this applies only to large atoms with many electrons around them, the ionization energies of lightweight atoms are completely negligible in comparison to nuclear forces - which is the reason, why they evaded the attention of hot fusion theorists completely.
/* About you comment on John S. Kanzius, let me say that I am not convinced */
And what? Most physicists aren't convinced even about cold fusion which you're trying to explain here - with such an attitude we would finish already at the very beginning of this thread... The skepticism without arguments is just a plain negativism: i.e. nothing very new at the LENR scene... To be honest, I don't care what the people feel at all: I do care only about what they can argue.
The electron shielding is actually the reason, why cold fusion runs preferably with elements, which form metal hydrides (palladium, lithium, nickel, titanium etc..) Inside these atoms the hydrogen ions (i.e. protons) get dragged beneath the outer orbitals, which gives them relatively negative charge - the hydrogen forms negative ions in these hydrides.
