Concept: Rotate 130 times on your finger and get 2-minutes of talktime

Jan 6, 20109:27 AM EST |

I guess you could call this a “green” idea as it takes no electricity… just human perspiration. This is a concept design by Song Teaho & Hyejin Lee that allows you to charge your mobile battery by spinning it around your finger. The battery has a built-in generator and the designers state that if you rotate it 130 times the outcome will be 2 minutes of talktime.

Would you use something like this?
