'Liters of light' shining in Cameroon slums

A common characteristic of informal settlements in Cameroon is the lack of indoor lighting during the day. To carry out any productive activities, households have to turn on the lights – for those who can afford electricity - or use kerosene lamps or candles adding to their electricity consumption and accompanying energy-related expenses as well as indoor air pollution. This gadget is an innovative passive lighting technology based on a transparent plastic bottle filled with clean water.
