To avoid high energy bills people in the slums of Nairobi are looking for alternatives. Youth group Koch Hope in Korogocho slums comes with an alternative, the water bulb (a plastic bottle with water and bleach). In daytime when the sun shines but the homes are dark inside you can use this cheap solution. In LungaLunga slums biogas from human faeces is used as an alternative. Your reporters for African Slum Journal are Eriss Khajira and Musa Chahare.
