Look up the Edison vs. Tesla power arguments for all kinds of information on AC vs. DC.This was under the assumption that the transmission line was at the same voltage as the end-user, because there were no good DC-DC voltage converters in that day. And a few bazillion amps at 120V needs a really fat wire.
To the many that (properly) corrected me: yes, this is what I was thinking about (well, that and the server I was restoring at the time). I wasn't aware that there are high voltage DC long-haul lines that then are converted to AC for local distribution. -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
