Could cell phone batteries be a thing of the past? Well a team of mechanical engineers at the University of Winconsin says, “You Betcha!” Well, not exactly in those words, we are paraphrasing a little But the team has created a magic device that stores up a charge just by the user walking around and doing their everyday stuff. The charge that is created and stored in the user’s shoes is enough to power a laptop or a even a mobile phone. Until now, engineers have not been able to create enough power to make our larger more fun power hungry devices go. With these new charging devices you may soon be working off those extra pounds and recharging your iPod at the same time as you can as the power will grow and flow as you move down the street.
