Plastic Bottle of Light

Plastic bottles are brightening homes and lives in the Philippines.光明之瓶。 在菲律宾，塑胶瓶不仅照亮许多人的住家，也照亮他们的人生.

People often recycle plastic bottles.  But Illac Diaz' s non-profit organization, MyShelter Foundation, has found another use for them. The foundation uses plastic bottles to bring daylight into the tiny, dark homes in Manila's poor areas. These Solar Bottle Bulbs provide cheap and long-lasting light to families who cannot afford much electricity.

People fill the plastic bottles with filtered water and bleach. The bottles are then installed into holes in the houses' roofs. This process takes less than an hour. Then sunlight enters the bottle, and the water allows the light to shine throughout the room. The solar Bottle Bulbs give off as much light as a 55-watt light bulb. And each bulb can last for five years. Such a simple and cheap light source greatly improves the lives of many poor families. The project aims to bring light to one million homes in Manila.

Diaz also hopes to take his project to other communities outside of the city. By doing so, MyShelter Foundation can brighten up the Philippines one bottle at a time.
