Actually, the article deals with the possibility of creating such a bra to power an iPod. It also mentioned that a solar-powered bra had already been invented! I looked into it and found a short article with photos. Whoa! Sorry, there's got to be a better way to power your iPod! Back to the drawingboard!
It does give one hope to think that inventor-types are trying to come up with green solutions to energy (or breast support) problems! It'll just take a bit of time.
For a history of the bra, look for Uplift: The Bra in America by Jane Farrell-Beck [391.4 FAR]. To get started in inventing, and selling your inventions, browse the shelves in the 608 section, look through The Complete Idiot's Guide to Cashing In on Your Inventions by Richard C. Levy [658.8 LEV], or, ask Santa for a subscription to Inventor's Digest for Christmas! (It's right around the corner!)
