Just as the epicycles were also correct. However, as I said, no one uses this theory anymore because it brings a lot of complications to explain certain phenomena. The energy flowing in the wires can be correct, however, you'll have a hard time to explain how energy flows from the primary to the secondary of a transformer, for instance.

So, Carpenter's article is more of an exercise in how it would be easier to understand certain simple situations, using Maxwell's equations, had the pundits who shaped the classical electromagnetism we know today chosen to stick to the initial intuition that the energy is contained in the wires. He doesn't say how it would be complicated to explain the rest.

Naej:
No one said it was very complicated to consider a battery as a 0Hz RF emitter.
But I'm glad you understand that energy flowing in wires is correct. As correct as Maxwell's equations, to be clear.

Now you're saying that energy flows from the primary to the secondary. Did you compute Poynting's vector? What is the result ?
Here's a McDonald quote: "This problem was posed by Siegman [1], which led to several conflicting responses [2, 3, 4, 5], all of which seem somewhat misguided". So don't look in McDonald's paper nor in Carpenter's and tell us.

At steady-state DC, the energy flowing in the wires perfectly explains the flow of energy from primary to secondary, just as it also describes the radiation from dipole antenna.  There is none.  So what's the problem?

OK. Fine. Stick to it. Until Derek posts a video with a battery, a switch, a piece of wire and a lamp and you don't know how to explain why the lamp will receive energy before the current manages to travel the whole extension of the wire, and you accuse him of being a troll, or worse, like others did.

Naej:
@bdunham7: There's no problem in DC nor AC, he knows that energy flows in the wires, he just doesn't find it convenient.

And somehow we need to speak about Poynting's vector to know that current appears to flow through capacitors now?
