Jim, here's a posting from last year that proves your assertion
to be false. I agreed with you last year that power doesn't
flow and isn't reflected. I agreed with you that it is energy
that flows and is reflected. I agreed with you that power is
measured at a point. Seems an apology is in order.

The crux of
the phenomenological problem is that power does not flow or move, nor is
it something that is reflected.


But energy does flow and move and is something that can be reflected.
You can easily see the energy packets using a TDR. Without energy,
those pulses wouldn't exist. The energy is obviously in the pulse,
where the voltage and current are.

And joules of energy flowing past a point is joules/sec, i.e. power,
by IEEE definition.
