Simon, the grandfather of Google Science Fair/Scientific American Science in Action prize winner Sakhiwe Songhe, lives on a farm in Swaziland outside Manzini where he has fruit orchards and keeps cattle, geese, and chickens. It is here that Sakhiwe and Bonkhe are conducting this year's follow up to their hydroponics experiments, showing the farming community that you can acheive at least twice the yield on Swaziland's poor land using compost to build soil. Solar CITIES went to the farm the weekend of August 23 and 24 and with the family and international volunteers built a Solar CITIES IBC/ARTI hybrid biogas system to provide cooking gas for grand-dad and fertilizer for the boy's science in action experiments as they go into their senior year of high school.
