Just imagine -- yapping for hours on end to your dream lover could actually leave your cellphone with more juice than what it started with. This completely bizarre scenario could theoretically become a reality according to new research from a professor at Texas A&M University, and it's all thanks to the magic of nanoscale piezoelectrics. If you'll recall, we've seen this technology generate energy in wearable devices before, so it makes sense that sound wave energy could also be captured and converted into electricity. Of course, we're still a good ways away from this being ready for commercialization, but who knows how quickly this could come together if placed in the capable (albeit unpredictable) hands of Dr. Walter Bishop.
