Dispelling myths surrounding the domestic dragon

1.  Does biogas pose a climate change hazard? Isn't biogas methane, the same gas that is 25 times more potent a greenhouse gas than carbon dioxide?

2.  Does biogas scale up? Can we use waste water treatment facilities to treat our food wastes?  If so, why wouldn't that be better than trying to do this at the home or community scale.

3. Could biogas be generated IN the kitchen, under the sink for example? Could it be incorporated into new kitchen designs?



Overview of our commitment to action for funders on the Commitment to Action by Solar CITIES

A simple way we use to visually describe how easy it is to build a biogas system

(The following questions and answers come from our application to the Clinton Global Initiative and can serve other organization desiring to know more about our work and commitments).

Brief overview of the work of your organization:

Cold Climate Adaptations - Experimental Week at Tamera Solar Village, Portugal

Cold nights and seasons are considered as an obstacle that keeps biogas solutions away from northern areas and out of permaculture and sustainability projects. The experimental week in August 2015 at the Tamera Solar Village was therefore dedicated to find and try out affordable insulations and heating methods that can be applied throughout the world.

Data Logging the IBC digestors

Data Logging is a crucial part of our work, but achieving the capability to do it reliably and cheaply isn't so easy.

Before I left for Florida I set up an Arduino with RTC (real time clock) powered by a solar panel for the internal digester in our Mercy College shed.  It started on May 18 and apparently lost power after 5 days on May 23. I just powered it up today, June 4, and got one reading.

The Solar CITIES Biogas Workshop and The Eco-Village Movement

Biogas Workshop in Tameram, TH Culhane in front

The recent workshop continued work that Culhane had done with the team at Tamera in 2011 when we held a Global Campus workshop to build Tamera's first kitchen-connected Solar CITIES style modified ARTI (Indian floating drum) digester, a delightful living fire breathing dragon now named "Holda".   Holda is  a 4 cubic meter work-horse (play-dragon)  of a biogas system fed on kitchen scraps who (who, not which, since she is alive) has now been in continuous and successful operation for nearly four years, going from a crawling baby to a running toddler.
