Have you seen this?

The Forever Flashlight uses no batteries or bulbs. Instead it uses Faraday’s Principle of Induction and a bright LED to produce light without batteries. The light is shaken for about 30 seconds to recharge a capacitor and it will then provide about 5 minutes of light. As the light is shaken, a magnet passes through a metal coil generating electricity. During prolonged use it can be shaken for 10-15 seconds every 2 or 3 minutes.

Plus, the bright LED will last for thousands of hours and does not burn-out like a typical lightbulb - it should never need replacement.Interesting. Worth a test-drive for sure.
