That's not a very good definition.
Would you say that a rock, thrown vertically, never was thrown just because
it returned to hit you on the head?


Nope, I wouldn't. But that seems to be what some people
are saying. I objected to that definition about 15 years
ago. I was asked to prove otherwise and was unable to
do so. The generated power is *defined* as the *net*
steady-state output power of the source.

That's why many of my examples involve signal generators
equipped with a circulator and load, outputting a constant
forward voltage in phase with a constant forward current.
