The Idea

The idea is as simple as it is effective. Ordinary plastic bottles are recycled and turned into solar bottle bulbs. This is done by filling bottles with water and a drop of bleach and next, installing the bottles in the roofs of huts in a slum. When the sun light shines through the bottle, the water spreads the light. Light as bright as a 55 watt light bulb is generated. Temperature-resistant glue ensures that the solar bottle bulb is waterproof and stays in place.
