No, this ain't some one handed, beta-male geek freak. And my interest in this mechanical mammary motion is strictly academic. Of course.
Actually, a woman, Adrienne So, wrote this article, and investigates the possibility of harnessing the often annoying (to women) kinetic energy inherent in an athletic female.
"Then one day recently I had an idea. As I rode public transportation to the office, my messenger bag slung uncomfortably across my chest, I thought, "Why not put the girls to work?" Human-powered devices are showing up everywhere, from Rotterdam's sustainable dance floor to human-powered gyms in Hong Kong. The time seemed perfect—perhaps even overdue!—for a bra that could harness the untapped power of breast motion.
Of course, even a bra that perfectly maximized motion (without sacrificing support and comfort) would be useful to me only if there were a way to turn that motion into energy.
For a primer on how to do that, I turned to Professor Zhong Lin Wang of Georgia Tech, who is currently working to develop fabric made from nanowires that will capture energy from motion. Wang's wires are about 1/1,000th the width of a human hair. When woven together in a fabric, these nanowires rub up against one another and convert the mechanical energy from the friction into an electric charge.
A square meter of fiber produces about 80 milliwatts of power, which is enough to run a small device like a cell phone. Wang expects to have a shirt available for purchase within five years."
I love science.
