If you’re trying to live green, try shaking the battery habit. Lots of simple devices around the house no longer need to rely on batteries. Consider at least using rechargeable batteries (an option that’s economical too), or really shake things up with a kinetically charged LED flashlight. Or get all cranky and wound up with a Wind Up 4-in-1 FM Radio, Alarm, LED flashlight and mobile phone charger or a Wind Up/Solar AM FM Radio . They even make wind up remote controls. One device that left me a little perplexed was the Solar-powered Flashlight .
