Really, Really Small Batteries

The atomic force microscope they use to manipulate nano-batteries at the University of Tulsa is in a fairly small room, but that's okay, they're dealing with a battery that's just 20-billionths of a meter, or 20 nanometers. "It's almost unfathomable even to us." While it's easy to forget, Dr. Dale Teeters says even a microscopic machine needs energy. "These devices that are going to be made are going to need power sources if they want to function autonomously on their own."
