Jed, I agree with our vision re. the competition between bulk and surface of Pd for D. It is about active sites on the surface call them NAE if you wish. The thirst of bulk for deuterium has a negative influence on the functionality of the active sites and therefore the conditions necessary for an usable energy source are not fulfilled:
INTENSITY- depends on the density of the active sites; REPRODUCIBILITY- if the active sites are inactivated by gases different from deuterium, good-by reproductibility! CONTINUITY- active sites are dynamic, they have to be generated constantly for long time It seems the fact that cold fusion (largo sensu) was discovered in palladium was historical bad luck to the field.
