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.
The light requires no maintenance so it can be left in your home or car for a longtime but will still be ready to produce light. The bright LED will last for thousands of hours and does not burn-out like a typical lightbulb – it should never need replacement.
I guess we can all wait for Dr. Mike to get one and give us a report.
P.S. to kids: now wouldn’t this be a neat topic to show a “real world” application of an arcane scientific theory???
