I have been wondering about the same questions. On the show doomsday preppers there have been a few "fancy" underground shelter builders. All have things like refrigerators, computors, washing machines etc. Are these people capable of makeing their own electricity long term? The computor thing is actually funny as hell. I guess they have a way to re-establish the world wide web. And the very big question is where is the air that they are going to breathe comeing from? Anything to get rich off other peoples fears! WOW
