Generate enough power to run a cellphone just by walking

We've seem bold claims about piezoelectric energy lately, and here's another example: energy-generating shoes. Engineers at Louisiana Tech University say they've discovered a practical way to gin up some power just by walking around.

Using a soft, rolled-up device that fits within the heel of a running shoe, electrical engineering Assistant Professor Dr. Ville Kaajakari says the tech might someday create usable power: "Ultimately we want to bring the power levels up to a point where we could, in addition to sensors, charge or power other portable devices such as cellphones."

We'll believe it when we see it.
