Brian: I think I see your point, i.e., your need to invoke the poynting
vector, but this seems to imply that a simple E field does not convey
energy. We all know that energy is stored in a simple E field, that the
energy density is proportional to the square of the field's magnitude,
why is that not sufficient to explain the (almost) immediate transport
of energy from source to load? Of course, it doesn't explicitly give the
rate of energy transfer.
