Most flashlights are useless since batteries have long since expired. Anything that can provide light without needing to be ignited, would be worth killing for to the right people. While I was out, I came across this flashlight from Goal Zero. It is a LED flashlight with solar cells for recharging. For those times when you do not have the sun to recharge the batteries, there is a a hand crack to recharge the light. I thought this would make a highly prized item in a post apocalyptic world. If you would like to get one yourself, they run 39.95 and you can purchase it at your local Target.
