I was wondering: what ever happened to the use of high voltage DC for
power transmission?  I understood that the high voltage inverters
needed were technologically feasible, yet I've heard very little of
this since.  It seems that this could reduce the varying magnetic field,
thereby reducing the voltage induced in objects nearby.  Of course, this
would raise the system's efficiency as well.

Mr. DC himself, Thomas Edison, would be proud.
