As commonly used with respect to engineered systems for production of useful mechanical or EM energy such as the production of light or heat, COP refers to the system output useful energy/ energy input.
The key is what is “useful energy” in above definition? In most cases it is assumed that there is a conservation of energy in the system being considered—that stored potential energy may change to useful energy—generally mechanical or kinetic energy. In this regard photons may be considered kinetic energy. if moving, or potential energy, if trapped. Thus a deeper understanding of the energy transitions which occur over time with respect to the engineered system being considered (transitions between potential and kinetic energy) is what is most instructive IMHO. For engineered systems that couple to the ZPE/ZPF energy source I would consider that source a potential energy, much like the potential energy of a fuel in a LENR engineered system. with the added benefit of always being available.

I looked at the few of these references and none of them mention COP wrt thermal feedback. As I said, that is because the COP is meaningless in cold fusion. However, as I also said, a thermal pulse often produces heat after death, with a COP of infinity. You can't ask for more enhancement than that! A lack of comprehension of the value of COP as an intuitive and accurate metric in LENR and the silly attempt to change its meaning is apparently guiding an uncharacteristic flood of disinformation… I do not see what is intuitive or accurate about a parameter that does not even exist in many experiments. Input power with electrolysis affects the formation of material, but it has nothing to do with the performance of the reaction itself. The reaction works with no input power during heat after death or with gas loading, so how can the ratio of input to output (the COP) be a critical parameter? I suggest you address that question rather than insulting top experts in this field such as Fleischmann, Storms and Miles. (They are the ones who say this, not me. Or not just me.) - Jed
