Geeks can definitely survive the end of the world as we know it (teotwawki). We have the technology, or we can make it. I wish I had the budget for this stuff:
ToolLogic Firesteel Knife
Fire good! This baby can start a lot of fires, which shall be important post teotwawki,
unless you intend to become a raw fooder, which I do not.
FreeLoader Pro Solar Charger
Keep your electronic devices running as long as possible, I know i wouldn't mind and extra six months or so to listen to my Zune! Great unless sun is obliterated, then hmmm... Put zombies in an exercise wheel maybe?
Dissolving Travel Toiletries
Well this should be an obvious item to stock in bulk. However, if you see no need for then now, then ignore this entry. ( For the sake of all of the teotwawki survivors, Please don't!)
Solar Power Water Bottle Cap
Light up your post-disaster pad!
