Rossi: Energy = Information Density

Andrea Rossi posted an unusual comment on the Journal of Nuclear Physics recently in response to a question about what he considers a definition of energy:

Dear Dr Andrea Rossi:
After your paper
how would you describe the term “energy”, like “energy =…” ?

Energy = information density in the space-time
Warm Regards,

I followed up with a question:

Dear Andrea,

A standard definition of energy is “the capacity for doing work”. Today you gave a definition of energy as: “information density in the space-time”.

Can you explain why you have such a different definition of energy than is normal?

Frank Acland:
“capacity for doing work” is a definition of an attribute, not of the intrinsic being. It is like to say that the definition of a car is ” capacity to move “: it is not a definition of a car, it is an atrribute of it.
Warm Regards,

I think this is more of a philosophical issue than a practical one, and really has no bearing on whether the E-Cat SKL works well or not, but it may be an indication of how Rossi is thinking about his work these days. When he speaks of energy in terms of information density, it may reflect his approach to working with the E-Cat where it seems that the alogrithms of his control systems play a very important role.
