As an aside, I just found this video.

As inconvenient as considering the earth flat. T'works for short distances. Fails in the long haul.

Carpenter's theorem states that if Maxwell's equations are correct, then JV is a valid energy flow. And with JV, energy flows only in wires.

So either:
a) you find a flaw in the 3 lines proof of the theorem
b) you find a counter-example to the theorem
c) you compare Maxwell's equations to flat earth-theory.

Conclusion: the statement "energy flows only in wires" is correct.

Dave: could you transmit the first message to Derek please?

But that can't be entirely true in the transient scenario. It's demonstrably true that energy reaches the bulb at 1m/c, and that can't go through the wire.
Am I missing something? Sorry, I have not been following this thread for 2 weeks.

He's already been bombarded with enough information.
SandyCox:
I'm still working through Farmer's papers.
In Farmer’s paper entitled:
“Electromagnetic energy and power in terms of charges and potentials instead of fields”,
equation (2) is the same as Haus and Melcher’s equation (24) from chapter 11.
So, the two are the same under static conditions.

My question is: how does energy flow from the battery to the resistor (bulb) under static (dc) conditions?
There is no displacement current nor induction under static conditions. How do we explain this flow of energy by relying on the concepts of electric and magnetic fields?

Carpenter's energy flow goes from the battery to the wires connected to it.
Current "goes through" (and Carpenter's flow does the same) the capacitor, and on the other side, wires move energy into the bulb.
Yes the theorem is entirely true.
