TreeHugger has covered the current wars between Edison and Tesla before, Edison did everything to defend his beloved DC, he even made a movie of an "execution" (you can watch it here) which he called being "Westinghoused." The rest is history and we thought DC was dead and gone.
So imagine our surprise to find that in New York City they just shut off the DC supply today. There are still quite a few buildings that use it, primarily for elevators (big AC motors were very hard to build) but now most of them have rectifiers to convert AC to DC and Consolidated Edison is finally shutting it down, replacing it with giant elevator-sized wall-warts. Doesn't smell like progress to me. ::New York Times
