While my avatar may be encouraging to those who feel that deriving energy from overhead 3-phase wires might be advantageous, I strongly advise not going near them. \r\n\r\nMy career in computers started in 1968 with IBM and things sure got a bit lighter when moving around in the last few years. \r\n\r\nMy career now is building RF devices for people at some universities to test the ionosphere with radiant electromagnetic energy. Things have gotten heavier, once again.\r\n\r\nThe best thing I can say about life in general is "Wait until you have grandchildren."\r\n\r\nThen it all becomes very clear.\r\n\r\nUntil then, greetings from Coal Mining Country in Eastern Kentucky!
