This spinning kinetic cellphone battery  is a smart solution for times when your phone is dangerously low on juice. With a simple twirl of your finger, you can charge your battery with enough energy to provide a couple more minutes of talk time or a number of minutes of standby. As we gear up for the 2010 Greener Gadgets Design Competition  we’re thrilled to see innovative ideas like this, so if you have a great idea for a green gadget submit it today !
Designed by Song Teaho & Hyejin Lee, the cell phone battery is recharged by simply placing it on your finger and twirling. As the diagrams indicate, twirling the battery 130 times will generate enough power to provide you 2 more minutes of talk time or 25 minutes of standby power. If a cell phone battery  like this ever gets manufactured and becomes popular, expect to see the next dance craze centered around twirling your finger.
With extra research and development, clean energy charging technologies like this one, will advance even further. But until we design and manufacture greener gadgets  powered by the with photovoltaics  or kinetic energy, we can’t stray too far from outlet.
