It was only a matter of time before breast implants paid for themselves.
A team of scientists has developed a silicone implant that generates small electric currents, powered by any kind of body movement -- such as a foot walking, a lung contracting or expanding, or a breast bouncing.
The Princeton University engineers behind the discovery say that their invention could power pacemakers, cell phones, and maybe someday power that new iPad. Which means the human body could turn into its own docking station. Overheard in the bar of the future? "Like my breasts? They can also charge your laptop."
