Wouldnt it be nice to be able to charge your cell phone by just walking? Imagine a charging unit (primarily made out of piezoelectric ceramics/crystals) mounted at the heel-bottom of one of your shoes, pumps out electrical juice on every step you make. Guess this kind of chargers could be a lot more
effective than hand cranking ones, because legs are stronger than arms.
The cell phone could be carried in an ankle holster, so the wiring to the charging unit is shortened. Otherwise, the long wire between your cell phone and the shoe makes you look really weird. Of cause, you can always hide the wire in your pants.
I think the same concept also works on the charging of mp3 player, PDA, and other mobile gizmos.
How does this idea sound?
Without the application to mobile phone. [sidi, Oct 04 2004]
||Good Idea. Alredy done though. (See link). You could
even afford a spare battery to put in your shoe, that
charges while you use the other (battery). Welcome to
||Whoops! Didnt see that. Hope something similar is already on way to the market. Id be among the first buyers.
||You got to my idea first.

||not a bad idea mate, not bad at all. One thing that baffled me at first...when you're phone is charging at your ankle, what do you do if it rings? but of course....bluetooth!
