New to the Emergency Kit....

I added a couple of these to the emergency kits...a big one at home and a small one at work. The big one works really cool - strong and bright. Waterproof and when you shake it for a couple of minutes you get a hour of light at least. The little one isn't as powerful (or waterproof) but you needn't worry about batteries. Well, that and the fact that I like to watch the wife charge them up. I'm using the Maglights for everyday use, the Surefires on the nightstand and with the ready guns, and now these shake lights for emergency backups. This flashlight brings to mind a device associated with some weapon systems I worked with. It was a chemical battery that when activated generated 90 minutes of AC (that's right - AC) power when associated with something called a "rotary chopper". It was top secret 40 years ago, but I expect kids make them in the basement now. Although I can find nothing about it on Google.
