    Default Penny power!

    I am sure osme of you have seen this type of battery before, but I think this is stil a cool way to power small electronic items. If the S ever hits the fan, this may be a valuable peice of knowledge to have!

    Wonder how many it would take to fire up a red dot reflex sight?
    If you didn't bring jerky what did I just eat?

    Probably a couple. I've got one floating around in my mess some place, so if I find it I'll give it a try.

    Had not seen this before. I learned how to make a really small battery with a lemon, a penny, and a dime, in 8th grade science. Any two different metals in an acid solution technically constitute a battery. With a little fine steel wool you could spark a fire. Good post WT!
