(PhysOrg.com) -- Whether you're away from electricity or you don't mind expending a few of your own calories, a new generator allows you to recharge it simply by shaking it. Its developer, Brother Industries Ltd, says that the "vibration-powered generating battery" can replace AA and AAA batteries for devices that have a power consumption of about 100 mW, such as a flashlight or remote control.
