Hi Richard,

I see you prefer to look at the world like King Lear and mumble
"Nothing begets nothing" then. This is all fine and well, but it
leads to unnecessary elaborations like:

Power is energy generated at some rate.

It certainly is, but Power has nothing to do with cancellation except
as a proof of two wave's energies combining to nothing. This is not a
"Nothing begets nothing" argument. Two energies pass without
interaction unless there is a load.

: A fixed rate means that after
total cancellation, redistrubited energy is the total,

It was, is, and will always be the same total, that is the meaning of
conservation of energy. Time alters nothing but the ability to push a
load around to map the distribution of power. Power is the summation
of all energies into a load.

and cancelled energy is zero.

There is no such thing as cancelled energy short of a Nuclear folding
of the universe. No, the total contribution of two energies into a
load is zero power. Each of those energies remains to contribute to
all fields or they would never propagate.

You can`t have your cake and eat it too (to coin an
expression).

Then you need to make your choice, are you eating (power), or are you
having (energy)? To attempt to say they both live by the same rules
is going to leave frosting on your face.
