Do you bring extra batteries for your flashlight when you go camping for days? Don’t bother with it, AsSeenOnTv.com is selling a flashlight using a simple implementation of Faraday’s Law of Induction to generate voltage.

During prolonged use it can be shaken for 10-15 seconds every 2 or 3 minutes giving you an unlimited supply of light.
