Energy is a description of what something does, not what it is. Energy is not a thing in itself.
From the bickering of the previous few posts, I would pick this as the comment most worth investigating. Not necessarily because it is true or false, but because, I think, it goes back to the heart of what I was trying to discuss in this thread.
Recall that the standard classroom definition of energy divides it into the two broad categories of kinetic and potential. DarwinX proposes to dispense with the concept of potential energy and model all observations in terms of kinetic energy. He does this by introducing novel concepts like the idea that potential energy is actually stored angular kinetic energy. When Thinking Critical points to the example of static electricity he is, of course, talking about something which would traditionally be thought of as electrostatic potential energy - charged particles held stationary within each others' electric fields. DarwinX will presumably counter this by asserting that the best model for this type of system involves some kind of angular kinetic energy of the charged particles or perhaps some kind of linear kinetic energy in some kind of ether.
This is all fine, and you can carry on bickering about it if you wish. But it won't get you anywhere other than to keep re-asserting that your own models of reality are the "real" ones and, at least in DarwinX's case, asserting that the competing models are deliberate cynical frauds with some sinister motive. Thinking Critical will then accuse DarwinX of being scientifically illiterate and paranoid, and the whole circus will continue in much the same vein as it does on most of the other science threads. The specific subject matter will become peripheral.
Personally, I'd prefer to examine
why and
whether particular models of the observed world ought to be adopted, rather than simply asserting that one of them should. My own view is that we should adopt the one that best describes the available evidence. My own view is that it is meaningless simply to assert that a particular model is self-evidently "true". It has to be demonstrated to be
useful.
I see no reason, on the face of it, why it is necessary to abandon the concept of potential energy and express everything in terms of kinetic energy. It simplifies our view of the energy concept, perhaps, but at the cost of introducing quite a lot of proposed behaviours, like these spin ideas, that are not observed to be present.
