@baldengineer @EXIT_FAILURE Yeah, one of them is definitely making the connection that it's the field transfering energy/power, not the wires...the Poynting vector etc.

Practically, that this is why e.g. a high speed signal is not "sending a wave of positive voltage / electrons" to a load where it then "returns" on a ground path (two legs), but instead propogates as a wave in the field between the two conductors (least inductance, etc)
