As simple as it sounds, a one-liter plastic bottle filled with purified water and some bleach could serve as a light bulb for some of the millions of people who live without electricity. Originally developed by MIT students, the "solar bottle bulb" is now being distributed by the MyShelter Foundation to homes throughout the Philippines. The foundations goal is to use this alternative source of daylight to brighten one million homes in the country by 2012.
