Edison's DC scheme was nonsense. At that time AC was the only viable
distribution system.
That high voltage DC is viable now, is caused by men with brain not by the brawn
of Edison.
Invention takes very little sweat but a high degree of brains, contrary to
Edison's assertion.
Edison was a tinkerer not an inventor. [ Reply to This | Parent | # ]

HVDC power distribution requires very expensive and maintenance-intensive
infrastructure compared to AC.
Modern AC Variable Frequency Drives still drive 3-phase AC motors, and can, and
have, replaced DC motors in most applications. Again, very high tech stuff
here.[ Reply to This | Parent | # ]

To convert voltages at DC you have to chop the current into pieces,
effectively AC. To connect the southern Japan 60hz grid to the
northern Japan 50hz grid there is a big* DC intermediary.
I declare a draw.
* Not big enough...[ Reply to This | Parent | # ]
