Power Suit makes own electricty?

that generates its own electricity,

making enough current to recharge a cell phone

or ensure that a small MP3 music player never runs out of power,

REUTERS Science Wire is reporting Feb. 18th.

If made into a shirt, the fabric could harness power

 from its wearer simply walking around or even from a slight breeze,

 they reported in the journal Nature."

The fiber-based nanogenerator would be a simple

and economical way to harvest energy from

the physical movement,"   Zhong Lin Wang of the

Georgia Instute of Technology,

who led the study, said in a statement.

The nanogenerator takes advantage of the semiconductive

properties of zinc oxide nanowires --

tiny wires 1,000 times smaller than the width of a human hair --

 embedded into the fabric.

The wires are formed into pairs of microscopic brush-like structures,

shaped like a baby-bottle brush.

One of the fibers in each pair is coated with gold

and serves as an electrode. As the bristles brush together

 through a person's body movement,

the wires convert the mechanical motion into electricity.

"When a nanowire bends it has an electric effect,"

Wang said in a telephone interview.

 "What the fabric does is it translates the mechanical movement

of your body into electricity."

Here we see Nicole Kidman wearing a prototype of an

outfit that could power a small home.
