Since 2006 the Solar C³ITIES team has been assisting communities around the world in the development of their own sustainability solutions.
Bring Solar C³ITIES home and community scale biodigestion to your community!
As a result of our Slovakia workshop, we held a biogas building workshop in Budapest, where I demonstrated the Solar CITIES IBC system for colder climates and enjoyed the crowd sourcing, collective intelligence nature of the participants, who came up with many great ideas for improvements!
As part of the Blackstone Ranch/National Geographic Innovation Challenge Grant, Culhane returned to Kenya and built digesters at the school of fellow Nat Geo Emerging Explorer Kakenya Ntaiya.
Working in partnership with the German "development through the arts" association, Simama e.V., a Solar CITIES enhanced ARTI digester was built at the Mukuru Arts Academy in Mukuru Slum, Nairobi by Minke Noordam and Nils Andersch from Simama and Mac teachers Henry Okayao and David Redmond in 2010.
February 3 through 5 of 2011 the Arava Institue for Environmental Studies held its Alumni conference in Aqaba Jordan. T.H.
Yube Boitumelo Siyangaphi, Joseph Kabimba and Kebonyemang Mashabe and I have built a three stage biodigestor at the worker's camp at CSU base camp, Selinda wildlife reserve, Botswana. It consists of a fiberglass-sealed 1000 liter horizontal digestor tank (primary digestor), a 200 liter used steel oil drum with a telescoping gas collector made from a second oil drum, chopped in two (with 5 cm cut out all around) and then brazed (torch welded) back together so it fits inside the first drum (5 leaks had to be patched with metal expoxy).

The Selinda system was sized to accommodate the kitchen waste from a maximum of 16 guests eating 4 meals a day. Culhane spent two days during a period of full occupancy grinding the waste generated through meal preparation and plate scrapings through the Insinkerator LC50 generously donated by Emerson Electronics and determined that each meal (breakfast, lunch, tea and dinner) generated approximately 2 25 liter buckets of slurry (food waste ground up with water).
In their first attempt to alter the conditions exacerbating deforestation and destruction of the Gombe National Park Chimpanzee reserve, Solar CITIES directors Hanna Fathy and T.H. Culhane joined Grace Gobbo from the Jane Goodall Institute to build the first two village digestors in the region (one in each of two villages in M'Kalinzi) where the use of firewood is rapidly eroding the edges of the wildlife park and two in the city of Kigoma on the shores of Lake Tanganyika, where charcoal use is having an even greater negative effect on the fate of the forest.
