New battery concept is finger powered

New battery concept is finger powered
Attempting to be greener these days can sometimes prove to be difficult; especially when functionality or aesthetics on a handset are compromised to accommodate such things. The concept of using another electrical source to charge a cell phone battery has long been adopted by manufacturers – which doesn’t seem to end in the near future. Every now and then, they throw at us some other practical way of charging a phone – such as wireless inductive charging for example. Fortunately though, one new battery concept aims to mend green technology with a unique twist in the way it gets charged. Designed by Song Teaho and Hyejin Lee, this concept borrows from those wind-up gadgets that allow them to function/charge by simply rotating a crank to get some juice. There isn’t a prototype available yet, but it involves you in twirling the battery around your finger to get it charged – no electrical source required; it’s all natural and powered by your finger. Designers estimate that 130 twirls will provide roughly two minutes of talking time. At that rate, it would take quite some time to get a decent level of power to make a solid ten minute phone call – still it’s human powered and does not require any other electrical source. Just make sure that your finger is in shape if this concept ends up becoming reality.

that is funny but if it was cheap I would get one as a backup plan

Ok that is cool but lame at the same time. Don't get me wrong going green is always the way I want to go but 130 twirls to power 2 minutes of talk time? How would that possibly be worth even having a cell phone?

I think that a lot of people would get this for thier kids. They have a phone for emergency's, and it's too time consuming to be able to go over your minutes. I bet if this does come out someone else will make a charger for it that spins it itself. Unfortunately it will be powered with a DC charger. haha. Now if they only put an actual razor on the new phone, I'd be all over it.

Standby time is only 25 minutes, kids would need standby time for "emergencies" too. Great concept, but not functional yet. It's like the electric cars that only drove 30 miles before needing a charge. Not practical yet, but we're getting there.

A pullstring design would be more efficient and get more power to the battery faster. Song Teaho and Hyejin Lee, you guys can have that one free of charge.
