I agree about the eyesore. In one city I was in, I noticed that as I moved from the poor to the rich neighborhood, all the power line (not trolly lines) were on poles in the former and buried in the latter; the difference was remarkable. I wonder if something can be embedded in the street. Obviously, a subway-style third rail would be a bad idea!
