Nanodynamite

Nanodynamite

One of the greatest challenges in all of technology right now is improving energy storage. It's an enormous challenge on many fronts and on many scales, with examples ranging from utility-scale batteries as big as a trailer down to the button-size cells that keep our quartz wristwatches ticking. And while we know how to make batteries bigger—add more cells—we are up against fundamental limits as we try to scale down rechargeable energy sources into the micro realm and beyond. It's probably not a challenge you've thought much about, unless you're designing the next generation of nanoscale memory-storage devices, circuits, magnets, or biosensors, which all need extremely small and rechargeable power sources. Most of the many researchers working on rechargeable power sources these days are trying to wring a few more kilometers out of an electric-car battery pack or a few more...
