Edison was right, even if he was wrong.  Back then it may have been
a ``good thing'' that Tesla won out, but it turns out that at the
voltages now in use on major power transmission lines have *more*
loss than they would if they were D.C.  (At lower voltages, A.C.
is less lossy.)  I don't remember where D.C. becomes more efficient
than A.C., but 760kV is above that point.

[Insert disclaimer:  this is all from memory, so don't trust it too
much.]
