think this is a good question to ask at this point
It is a good question but then there are so many questions that need answers in LENR.
The most unconventional idea is that Vysotskii seems to show that Cs137 transmutation is exhibited by bacteria.
This means that the switch on of the magnetoelectrical cooperative whatever effect can be at < ev level..
not at the ~Mev level as predicted by conventional Coulomb barrier thinking...
but these switched on effects are huge.
The switchon does not happen everywhere because otherwise we would be dead
It's to do with nanostructure arrangement, isotope isomer population mix
