The ATMs that dispense clean fuel

Sleek blue machines have been popping up in convenience stores across Nairobi over the past two years. These “Koko points” look like cash machines but instead of giving out money they dispense bioethanol, a fuel made from plants which can be used in cooking stoves. At the moment 80% of Kenyans use wood or charcoal as their main cooking fuel – but these materials have a devastating impact on the environment, and the smoke causes hundreds of deaths every week. Koko’s high-tech solution offers Kenyans a cleaner alternative, although it means a move away from some dearly-held customs. Reporter: Mercy Juma Producer: William Kremer
