	Higher currents for the same amount of power mean more losses. Also, more material is needed to make the conductors to carry the extra current. Which means more weight. Which means any overhead structures need to be more massive and obtrusive compared with LT. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
