Sure, but it’s the breast power you really want to know about, isn’t it? A Slate article examines the possibility of charging portable electronic devices via the energy generated from the movement of breasts while running, for example. Don’t laugh: it’s possible, and apparently the science of breast motion has been studied for years.

It appears that one of the best bets for capturing energy from motion is from Zhong Lin Wang of Georgia Tech, who is currently working to develop fabric made from nanowires, the article reports. The nanowires rub 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.

Honey, these would pay for themselves in a year in electric savings alone!
