As far as I know, all you've written is a fact. Around me only AC is common, there seems to be no DC grid in the Ruhrgebiet. One exception, I'm not sure if DC has less loss. When a friend and I had a Morse telegraphy line, low voltage, relatively long distance, when we were kids, it seemed to be that AC was a good choice, but we didn't use DC and compared it to AC. Hm? Long distance= high voltage, regarding to the loss. Is there really a difference between AC and DC? I'm an audio engineer, so I have to deal with AC for speaker cables, AFAIK there's no choice to use DC ;). -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
