Hi guys,
I've got this concept of a flash light that would be used only in emergency when being stuck in a cave. It would be a little torch that's able to emit light for at least 1 week continuously, so you won't be sitting in dark until being rescued. Regarding it's size, it could easily fit in a small pocket.
I know, that some headlamps have this function, but this would be dedicated, always fully charged, and really cheap. What do you think of the idea, would you have it with you? Or have you seen or got something like this yet?
