That's why I am willing to switch from the words "Reflected
Power" to "Reflected Energy" and measure that energy flow
past a point on a transmission line in joules/second.


SNIPPED

Energy FLOW implies a unit of time. Flow indicates a flow rate. In the
absence of a flow rate you are discussing static conditions.

Conclusion: all the illogical rational in the world does not change the
understanding of energy flow energy/unit time = power = watts =
joules/second pass a point or dissipated.

Cecil, as an engineer you should stick with standard vocabulary.

Dave,

I couldn't agree more. Energy flow is correct. Power flow is a bit
more controversial. In some cases the notion can lead to power being
reflected, algebraically summed, and it can ultimately interfere
constructively and destructively. It can even, by making exactly the
right misinterpretations, end up changing direction without the aid of
a reflecting surface. That's why it can sometimes be important to
make sure the hairs are properly split. :-)
