I have a “forever flashlight” — the kind that you shake for 20 seconds and get 5-10 minutes of light. This flashlight seems to be an improvement on that idea. It uses three ultra-bright LEDs. One minute of wind-up provides up to one hour of light. It’s available from Amazon.

They should make more electronic products like this (cell phones, mp3 players). =]
LED’s require very little power. May be hard to power anything that requires more energy. (many watches already use a similar mechanism)
I bet the battery companies would hate it if they made more stuff like this!
I got this light a few weeks ago, still havnt had to crank it up, does this have a battery or a capacitor(s ) ??? I wanna take it apart and look ,dave
