Of course not, power does not follow the superposition

I've reviewed some of your writings and you have said this
at least as far back as 2001. This is good.

So why did I think otherwise? I think it is your reliance
on Ptot = Pfor + Pref. I see this as an expression from
superposition much the same as Vtot = Vfor + Vref, but I
gather from the paper on your web site that you do not,
rather you see it as an expression of conservation of
energy.

From re-reading your paper, it seems that your thinking
all derives from trying to satisfy the principle of
conservation of energy. This is good. There is general
agreement that energy is conserved.

But them I am confused with your ready acceptance of
Ptot = P1 + P2 +/- Pinterference

Given a P1 that actually exists and a P2 that actually
exists it seems to me that Ptot must equal P1 + P2.
Anything else would fail to satisfy the principle of
conservation of energy.

To make the expression work, +/-Pinterference must
be creating or destroying energy. Given my understanding
of the physical world, this seems most unlikely.

Can you elaborate on how +/-Pinterferance creates or
destroys energy while still conserving energy?
