Power up

I have been thinking a lot lately about what I will do this winter if something happens that we would lose power here in the house due to an ice storm. I know I would not have to worry about heat for the house and cooking since we do that with gas. After spending time in Haiti I can do without the electricity if I need to I have a ton of candles that we could use for light. However the one thing I wonder about is my laptop. I mean without my laptop I am a lost person. I know I have the battery power but that doesn't last forever. So I have been thinking about some extra laptop batteries. I think this is really something that I am going to give some serious consideration to.
