i recall in school a lecture on why we got ac in the first place. turns out, those arguments used then are still valid today. if all electrical equipment were to suddenly disappear and need to be totally replaced, we would set up ac again, although the voltage might go a bit lower and frequency would be made the same the world around.

although point generators are likely, i think the copper grid willcontinue to to be useful for a loooong time as a power distribution system and a possible waveguide for communications, such as web access and tv signals. there's no reason why the power company cannot get into the game of information distribution over the infrastructure they have already built. spike
