While not really intended for developed countries the start up M2E Power, based in Boise Idaho, announced that it will start selling a cell-phone charger next year that can convert every day movement into energy for cell phones. The micro-generator device is designed to convert regular motion, like walking the dog, grocery shopping etc into power with the charger said to be able to convert six hours of everyday movement into an hour of talk time. In the future, the company planes to embed its micro-generator with integrated battery storage system into the mobile phone itself. While not really suitable for developed nations with good electric infrastructure the motion-harvesting mobiles fill a real need in developing nations with inadequate power grids, off the grid adventurers, or most importantly the military.
