Creative minds are searching for alternative energy sources in all possible places. Slate take a look at harnessing the untapped power of breast motion. Could the power of the jiggle recharge an iPod? Scientists think it might be possible. LaJean Lawson, a former professor of exercise science at Oregon State University has been studying breast physics since 1985.

Lawson explained that breasts move on three different axes: from side to side, front to back, and up and down. The most motion is generated on the vertical axis. Naturally, the bigger the breast, the more momentum it generates. "Let's face it--if you're a double-A marathoner, you're probably not going to get that iPod up and running," Lawson said. Measurements compiled by Lawson and her colleagues show that a D-cup in a low-support bra can travel as much as 35 inches up and down (35 inches!) during exercise, while a B-cup in a high-support bra barely moves an inch.

Other researchers who study kinetic energy are intrigued with the idea and how to make it happen. Nanowires? A linear generator? Who knows, but someday soon, those things might be good for something.
