This Yo-Yo Charges Cell Phones
Our current energy crisis is spurring some novel ideas for generating electrcity. Design labs around the country are churning out ideas like this cell phone-charging yo-yo, which can generate small amounts of energy to power personal electronics in hopes of taking that small burden off the grid.
The cell phone-charging yo-yo is a simple concept: A conductor and a magnet are housed inside the yo-yo, and energy is created as the yo-yo spins. The charge is then held in a battery which can be connected to a cell phone, providing the power to place calls.
If it ever gets manufactured, you'll be able to keep your restless children (or inner child) busy while squeaking out some extra talk time on your iPhone. Check out the video concept after the break. [From: Textually.org]
