Forgot your charger? No problem. Scientists have developed a microfiber fabric that can generate enough electricity to juice up a cell phone or a mini-music player. If turned into clothing, the fabric would get its power from the action of your daily movement. The material uses zinc-oxide nanowires that are arranged in pairs—one wire in each grouping is coated with gold, and serves as the electrode. When the fabric moves, the wires move and bend, and the fabric translates this mechanical energy into electricity.

Stanford researchers have figured out a way to incorporate silicon nanowires into rechargeable lithium ion batteries and extend their life from 4 to 40 hours. The work, described in a paper in Nature Nanotechnology, could lead to iPods, laptops and camcorders that could be run nearly for an entire weekend without requiring a re-charge. Of course, this is still in the lab stage, and there are undoubtedly quite a few steps and hurdles between the campus and commercialization, but we're optimists. So, here's to the end of the ABC (Always Be Charging) Rule of electronics.—Gregory Mone
