Normally I wouldn't work a book review into Fit Beauty, but this is just too perfect. I recently read Nina Garcia's The One Hundred: A Guide to the Pieces Every Stylish Woman Must Own , and just like watching an inspirational sports movie makes me want to hit the gym, this book made me want to shop.

But there's more to it than just bouncing them around enough to create energy -- that energy then has to be harnessed. Slate recently had an article on what would need to occur in order to harness the power of our swaying breasts (I mean actual energy power -- not the power to stop men in their tracks or knock over a small child), and believe it or not, there's some serious technology already at work regarding this. However, each possibility has its problems. For example, one researcher has fabric made of nanowires that could easily be used to create a bra. However, it couldn't be washed -- ew! And then, there's the Lightning Pack technology that's already at work in backpacks for serious hikers and the military, and while this technology could be used on the bra strap, there's a generator and a pist...
