Good point, Richard. Wf = Wl + Wr. Amidst all this consternation about
conserving the energy in canceled waves, we should not lose sight of the
fact that it is *reflections* (not canceled waves) which cause forward
power to measure greater than power dissipated in the load.

Now all you have to do is figure out how those reflected
waves reverse their momentum to become forward waves.
You have never offered any explanation for that phenomenon
while criticizing everyone else's explanations.
