Adrienne So over at Slate has used her natural gifts to come up with the most genius idea yet: an energy-generating bra. Instead of just holding her boobs in place and dispelling that excess kinetic energy into, I don't know, heat, why not use it to power a gadget? According to a breast specialist, a D-cup in a lousy bra moves up to 35-inches up and down during exercise. Professor Wang of Georgia Tech is working on just this problem, using nanowires inside fabric to convert that visual spectacle into something useful. But is it enough to power an average iPod? This Wang says yes. [Slate]
