Whatever floats your boat, Richard. If you need to think of power as an
'ability' that flows through an electrical pipe, then I think you should
think of it that way.

From the Random House American College Dictionary:
Power is the ability to do or act. It is the time rate of transferring
or transforming energy. It is work done or energy transferred per unit
of time.

The power to do or act can be moved from one location to another. A
power house is an electrical generating station where some other form of
energy is converted to electricity which is very flexible in
application.

From the power house, the power (ability to do or act) is transported by
power transmission lines to the places it is used.

Since the wavelength at 60 Hz is 5 million meters, (5000 km), power
transmission lines aren`t long enough to produce standing waves which
are caused by reflections.

Radio-frequency transmission lines are often long enough to show the
effects of reflections and the standing waves produced by those
reflections.

Power flows in r-f lines and it is reflected at impedance
discontinuities accordimg to the most knowledgeable experts. F.E. Terman
is my favorite.
