What do batteries run on?

I know, I know, it's been week or so since my last post. I've been busy trying to avoid working. I start a new job on Wednesday and I've been busting my butt doing paperwork to get security clearance since my new job is for the government. I've never seen such red tape. You could rebuild the pyramids at Giza with this crap. But I suppose it's worth it as I will be working for our troops overseas. Whether you like it or hate it, you must respect it. My father, grandfather and father-in-law were all in wars. My father-in-law the most decorated soldier in McDowell county. He fought in 2 wars, WWII and Korea. I'm very proud of my family and their history as soldiers. I mean it is Memorial Day after all.
