NightStar Human-Powered Flashlight

NightStar LED flashlights are sturdy and bright, but even better, they use the Faraday principle of electro-magentic induction to generate electricity. By simply shaking the tube of the gadget for 20-30 seconds, you get up to 5 minutes of continuous light; the entire device is rated for more than 100,000 hours of use. (That's one hour/day for 271 years, according to the Web site.) With no bulbs and no batteries, these babies are good to go in an emergency, or any time you need them.
