Cow dung power
Picture of biogas project at Nakuru High School in Kenya. The pupils and teachers have designed, and are now promoting, a cooker that is fuelled by cow dung, of which Kenya has no shortage. Kenya does not get any electricity from solar technologies, despite being right on the equator. The reason is essentially the cost of installation. Sunlight is free and, in Africa, is certainly plentiful. However, solar photovoltaic panels or Concentrated Solar Power plants (which use mirrors to boil water and then use the steam to generate electricity) are not yet cheap, although the costs are falling.

Agent Shakwei, thanks for sharing this powerful picture. This idea to me seems to become more sustainable considering the pupils are part of the implementing team. This implies that the pupils attain the skills and widely share them with their home communities. :)

Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
