A keychain style white LED light, that runs off a SuperCapacitor, Lithium cell and micro-Dynamo.
The light itself is a thin Green plastic rectangle that has a membrane switch and a small lanyard chain attached to a strong nylon rope, as well as a small hole for the LED.
Normally the light is powered
from the Lithium watch battery, which should last a few hours with very good regulation.
When that runs out, the secondary power source comes into play:
The Lanyard when pulled will wind up a internal flywheel that will power the micro-generator and charge the super capacitor. Similar to how some flywheel wind up toy cars operate. This mode of operation will provide several minutes of operation. The flywheel may have to be pulled several times to get a full rotation speed, but at that point it will keep the capacitor charged until it slows down. The capacitor itself will supply a few minutes of slowly dimming light.
The casing itself is water resistant (the electronics are sealed against moisture, the mecanical parts are not. The plastic is a glow in the dark type.
The flywheel is really just a large neodymium magnet coated with teflon.

Not sure if that's a glow in the dark green plastic housing. [jurist, Jan 16 2006]

Sounds good, but they already have something like that on the market. Only difference is that you shake it. |

I own such a light. It is nifty. |

Some kind of illumination for Americans? |
|

So, Do you prefer to yank it? or shake it? |

I think the idea of a lanyard that acts as a clockwork generator is really neat. [+] |

I think it's a good idea, but I admit I'm a little old fashioned, and when I use a flashlight, I want only the brightest on the market, which is why I go with Surefire, and you don't have to worry about not having batteries because the damn things have a shelf-life of ten years. (they use a special kind of CR123 camera battery for high output) Still gets my vote though, because I know I'll be the moron who eats these words some day and wishes I had one of these newfangled contraptions. |

Just hang if from your belt buckle and give it a few yanks erery once in a while to keep it charged. |
