So, when I asked about what happens in the micro cracks after fractofusion has opened them up Eric Walker gave me a link to this document of fairly recent date:

Explaining Cold Fusion by Edmund Storms
In this paper Ed draws an outline of a mechanism that he considers to be capable of producing cold fusion between pairs of deuterium atoms.
The nuclear-active structure, called Hydroton, is metallic hydrogen that forms in the nano-gaps.
A Hydroton can be pictured as an open string of deuteron pearls held together by covalent bonds.
The chain resonates along its axis, which allows two nuclei to periodically get close enough to start the fusion process by emission in opposite directions of a weak coherent photon from each nucleus.
The resonance cycle briefly terminates this process before additional photons can be emitted. Another photon set is emitted at the next cycle when two nuclei briefly again get close enough to pre-fuse.
This periodic emission of photons takes place until all mass has been converted to energy and the two nuclei become a single nucleus. The photons have a range of energies, with most of them being absorbed by the apparatus.
This will not work. The fusion energy is liberated only when the deuterium nucleuses are close enough for the strong force to do its work. This distance is just about 3*10-15 m, whereas the size of a hydrogen atom is about 1*10-10 m. The strong force cannot deliver any energy at distances larger than a few femtometer because there is no strong force in this range.
