Crank a Log to Charge Your Phone (BoingBoing)

[Drew Wilson]

This hand-cranked cell-phone charger mounted in a hollowed-out log was apparently discovered in Chechen fighters' encampment. Some of the components -- the pull-string, presumably -- are said to come from toy cars.

I'm sure there are a few who stiffened over the idea, thinking that this link had their number until it was discovered that the meaning was actually literal.

:burnout:

Ingenious nevertheless.

I'd give these guys a task to design a ZP flashlight then.:32:

Hmm wonder if this was hand powered, or whether they had a large mass that would be suspended a released to use gravitational energy to charge the phone. Fairly well thought out either way.

It looks like a hand crank. The whole assembly is not that big judging from an image of a lighter.




This looks like a form of a dynamo (the one you would have on your bicycle).
