Hint:
people who write physics books know that power does not interfere.

Please tell that to someone who disagrees with
that statement, Jim, which is not me. Here's what
I said in my years old energy analysis article.

"The term 'power flow' has been avoided in favor of
'energy flow'. Power is a measure of that energy flow
per unit time through a plane. Likewise, the EM fields
in the waves do the interfering. Powers, treated as
scalars, are incapable of interference."

You keep making statements like the above in hopes
someone somewhere will believe that I disagree with
it. Old trick - doesn't work.

I say, *EM WAVES DO THE INTERFERING*. Do you want
to argue about that?

I say, *POWERS ARE INCAPABLE OF INTERFERENCE*. Do
you want to argue about that?

Please, if we are going to argue about something,
make it something upon which we disagree.
