Bring Solar C³ITIES home and community scale biodigestion to your community!

Basic training opportunities in small scale biogas build confidence and familiarity with biogas before launching into a larger community size build.

Working with the American NGO  "UrbanBioRecovery: Digesters for Development" (originally called "Solar Cities Solutions" from 2012 through July 2014)  Solar CITIES e.V. intern Jorma Gorns joined T.H. Culhane on a project bringing Puxin 10m3 biodigester molds to sites in Rio De Janeiro.  The initial work was done by Solar Cities Solution's "Biogas Education Team" members T.H. Culhane, Yair Teller and Marcello Ambrosio, working with Dr.

The project in Al Najaf, Iraq was run by our member Taha Majeed Lafta, Chemical engineer form the Ministry of Science & technology, Renewable energy directorate.

On June 17th, Joseph Grimaldi and Christopher Lindstrom and T.H.

Envisaj Mercy, the Mercy College Environmental Sustainability and Justice League Biogas team traveled with Culhane to Lancaster Pennsylvania to build a backyard biogas system at the home of the Kelseys from Juice Plus.

Our second small scale biogas build in Turkey following the one I did the previous year at the same time with Yaşat Hacıbaloğlu -- the network of biogas investigating youth grows ever stronger and brighter -- things have been stalled here in the DIY realm because youtube is banned by the government so it isn't easy to access open source video instruction, but there is no substitute for face-to-face workshops anyway, so I am privileged to have been able to share a solution with the students of Koc University's Environmental Engineering Club this afternoon/evening.

Culhane innoculates the ARTI side of the Solar CITIES IBC/ARTI hybrid with cow manure from the Kibbutz

We  built this Solar CITIES IBC/ARTI Hybrid Biodigester system on January 15th at Kibbutz Lotan after Culhane field tested the new design early in the fall at Mercy College. The new idea was to use buckets for the feed in and slurry out, simulating a Puxin or fixed dome digester using water displacement to allow for some gas build up in the IBC and creating water pressure to force the gas out. It also gives an ability to easily pour food waste in, acting as a "mega funnel".

In 2011, at the end of the Arava Institute Alumni Conference in Aqaba, Jordan, at which T.H. Culhane was the keynote speaker, a team of alumni and Culhane crossed the border to Israel with Arava biogas expert Yair Teller, and built two "salchicha" flexible bag type digesters at the Arava Institute in Kibbutz Lotan.

On April 27, 2013, at the end of my presentation tour for Earth Week, an enthusiastic student who had attended one of my talks, Yaşat Hacıbaloğlu, asked if he could learn how to build a home biodigester.  Since I had a "day off" where Bosch/National Geographic/Fox was going to treat me to a day of sightseeing I decide instead to ask the driver if he could take me and Yasat into the local market to buy supplies and build a Solar CITIES style ARTI biogas system.

After the midnight build of a Solar CITIES modified ARTI  biodigester in Erbil, Kurdistan tonight, during my last night in Iraq with new friends Maw'eid and Bryant and Dave (construction, security and IT professionals) , we said prayers in Arabic and English and each put some of my Iraqi grandfather's ashes in the tank so that his spirit may live on with the humblest yet most impactful of God's creation, the Archaea, helping guide their transformations toward the renewal of this proud and ancient civilization.
