What about the Poynting Vector and Power Flow Vectors?
What about the 60 Hz "power generation" and "power
distribution" system?

Are you saying that the trailing edge of an ExH wave
is not moving? Are you saying that the ExB power in
the light from Alpha Centauri didn't come from Alpha
Centauri?

What about them?

What are you trying to imply about power generation?

"Power distribution system" is really a misnomer. In the present day
venacular it would be called exactly what it is - an "energy
distribution system".

I don't recall ever expressing the opinion that traveling waves don't
travel.
However mathematical formulas do not propagate along transmission
lines. Fields do, but there is no such thing as an ExB "field".

Good grief, Jim, ExB is proportional to the irradiance of a light beam.
I'm sorry if my ASCII-limited character set hairlips you.

Good grief, Cecil, irradiance isn't a field and doesn't propagates
either!

Hi Jim,

Nearly every posting that Cecil pens with his rustic understanding of
Optics suffers from the obvious lack of experience.

There is a certain amount of pretense in this irradiance (an archaic
radiometric term used incorrectly for photometrics in an argument that
calls for luminous flux), much like quoting I²R and not knowing what
Ohms or Amperes are.

He's lucky there are so very few that appreciate the gaffs of his
unintended humor.

Everything I write about light/optics comes straight from
_Optics_, by Hecht. I assume he is more of an expert than
you are and he uses the term "irradiance" for the power
contained in a light beam. Hecht's interference equations
involving irradiance are identical in concept to Dr. Best's
power equations in his QEX article.

Still enjoy the gaffs tho' Great show! ;-)

As I said earlier, irradiance is proportional to the cross product
of the E-field and B-field. Why do you think we call them fields
if they are not fields?

Exactly how does the irradiance from Alpha Centauri get to
us without propagating? Methinks you are playing word games.

A smile a minute ;-)

How does a money wire transfer get into your account without moving
from the mint? [Hint to the literate: irradiance does not move,
neither does the money in a wire transfer.]

Cecil says that a credit card is money, and presumably so is a wire
transfer.
All things are indeed, equal - apparently.

Amazing analogy though - a power debit from one account, a power credit
at the other - without power (or irradiance) having actually traveled
the distance. All owing to the facility that transfers energy.
