Consider this:
  Had DC won over AC:
  a) Battery technology would be ahead by 100 years, instead of
  stagnating for decades due to the dominance of electric
  b) battery powered cars would be a common reality by now.
  c) The oil/coal it takes to boil the steam to move the
  generators to make the a/c wouldn't be as commonplace. It's
  likely our dependence on oil/gas might have been curtailed had
  we gone to DC

  Yet at the same time:
  Electric is to thank for a lot of our progress - EVEN THOUGH the
  majority of household appliance internally *WORK ON DC* -
  including my laptop.

  Food for thought.

  Tesla's reputation as "unrecognized genius" is a bit
  over-stated. He was an interesting man but I honestly don't
  understand the devotion so many have to him and I have a number
  of friends who are Tesla devotees, so I get to hear about it
  frequently.
