In a lighter tone than my last post, I present to you all the way to power those small gadgets that you have on you at all times. I'm talking iPods (though I do not have one, and in no way condone supporting Apple), phones, and other various things you may have with you during your average day.
The innovation comes in the form of polyvinylidene fluoride, a fabric that absorbs static electricity created by the act of walking. Apparently, it does not produce much energy, but more than enough to power those little devices, and much more than is needed to power a small LED light.
The first object that will be used in conjunction with the fabric is a backpack, although someday more complex things, such as full clothing, may allow us to charge our MP3 players just by walking around school.
