For me, they really are going to need to explain how fire can burn and water can boil but there are no steam powered technologies ANYWHERE! The fact that there is a bloody still in the bar proves that that technology should work just fine. Hell, I'm from Chicago, so I know for a fact that the Museum of Science and Industry alone has some of that stuff on display and more in storeage. This series could have kept everything in tact but made it into a steampunk mystery/adventure series....but no, instead it just does not make sense. One thing I am curious about...if there is no electricty, does this mean no lightning? That might explain why the cities (and everything else) did not burn in the immediate aftermath.
