An innovative initiative is taking place in the Philippines to bring sustainable lighting to homes in impoverished communities. Empty plastic bottles are installed in the roof, filled with water and bleach they refract sunlight. These “solar light bulbs” provide light equivalent to a 55watt light bulb.
See how they’re made here. From Visual News
Aaaaaaand what’s the use? Those “light bulbs” will only work when lighted by sun :|
