A Quake Shake Creates Light

The batteries in my flashlight are often dead when I grab it. So in an emergency I always have to be sure I have a supply of the right sized batteries. But imagine you're in an earthquake, and all you can reach is your flashlight. Wouldn't it be cool if the thing got a little charge from all that shaking and just worked? And how great that it floats and works under water, too! Then there's the added treat that it's eco-friendly, with no batteries to recycle.

Keep your light burning till help arrives with a little shake in extreme hot or cold. 90 seconds lasts 20 minutes. Thanks, Daily Grommet gals!

No batteries? No problem. The NightStar CS2 is the world’s first renewable energy shake flashlight. Just shake it for 90 seconds and you'll see the light. NightStar uses repulsion magnets to rebound the charging magnet, which is the most efficient way of de-accelerating and re-accelerating the charging magnet.
