Step Toward Liberating Electronic Devices From Their Power Cords 130

Science_afficionado (932920) writes "A new type of supercapacitor that can hold a charge when it takes a lickin' has been developed by engineers at Vanderbilt University. It is the first 'multi-functional' energy storage device that can operate while subject to realistic static and dynamic loads — advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries. These devices could make it possible to design electrical devices that are not limited by plugs and external power sources."

    My cell phone needs charged at night, but I don't consider it to be a wired phone and I don't find the charging cord to hinder me when making calls. My laptop, on the other hand, stays plugged in most of the time because it won't last a full day otherwise. It is hampered by the power supply.

    I think the idea here is that short term charging for devices is necessary, but normal operation would be wire free, thus they are liberated from wires.
