Kibera, Nairobi - On Oct 1st 2012: Schooling at Adventure Pride centre. Millions of poor schools and homes in Kenya and far more around Africa and the world are left in the dark because metal rooftops block all light and there are no connections to the electrical grid in cramped informal settlements. This simple bottle bulb, installed through a sealed hole cut in the metal roofs, provides a surprising amount of light by deflecting sunlight into gloomy interiors.
