<<4. What percentage of the high-voltage lines that one sees in the countryside are AC and what percentage are DC?>> <Almost all are AC...> I don't think this is correct. I've seen pictures of huge (I mean 40-60 feet tall) thyristors, which are supposedly used for line synching high voltage DC transmission lines to a local grid. I believe the article mentioned that DC transmission was efficient enough to more than overcome the conversion losses. I didn't work out the math, nor can I recall the publication. Anyone else know something about this? :::::: Software Productivity Technologies -- Experiment Manager Project :::::: :::::: Jan Steinman N7JDB Box 500, MS 50-383 (w)503/627-5881 :::::: :::::: jans@tekcrl.TEK.COM Beaverton, OR 97077 (h)503/657-7703 ::::::
