Agree it is "relevant" to power density and less so for energy density since it is only certain metal lattices that possess this property and the property is far more dependent of the broken geometries of the lattice..how often and to what extent defects occur seems more important than the volume even to the point where researches have to track manufacturers and lot numbers of the metal lattice to be certain they get the same materials capable of exhibiting these anomalous properties.
I disagree with this portion of your reply [snip] Since the actual source of energy is likely to be the Hydrogen in the water, not the actual cathode metal, the volume of the cathode is pretty much irrelevant [/snip] Yes the energy may come from the gas but it is the lattice confinement and change in level of confinement at the defects that provide the environment that liberates this normally inaccessible source of energy from hydrogen - We don't have to accept ZPE, hydrino or hydrotron to all agree that defects in lattice geometry, their population density and their topologies allow this energy to be produced such that you have to consider the hydrogen and the containment together as the actual energy source so Jeds' focus on the cathode geometry as a crude metric seems viable.

Since the actual source of energy is likely to be the Hydrogen in the water, not the actual cathode metal, the volume of the cathode is pretty much irrelevant. (It is probably relevant for power density, but not energy density). Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
