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.

Envisaj Mercy Environmental Sustainability and Justice League Student Club builds biodigesters abroad

A year after our Envisaj Mercy team went on the "mother of all biogas tours", a faculty-led service learning expedition  to Israel and Palestine, visiting Eco-gas Isreal and the Palestinian Wildlife Society and introduced our Solar CITIES IBC/ARTI hybrid biodigester to the Green Apprenticeship Program in Kibbutz Lotan, we found ourselves on a "student-led" service learning expedition in the Dominican Republic where several of our Envisaj Mercy club members have family.

A Solar CITIES team member aspires to be a "Possibility Manager"

As we work to define our roles in the Solar CITIES movement around the world, clarity comes from considering that what we really aspire to be are "Possibility Managers" in the sense discussed by Clinton Callahan. These paragraphs from his book "Adventures in Thinking" do a good job of summarizing how a Solar CITIES team member should approach the work:

Virtual World Building and the Realization of Eutopias

There was a time when only planners and architects and engineers had access to the toolkits necessary to turn dreams into realities.

Those days have changed.

For several years now, would be world builders have had a plethora of pre-visualization tools at our disposal.

Blogging as a way of getting serious thoughts together for Academic Publishing, by T.H. Culhane

When I was pursuing my Ph.D back in grad school, starting in 2000 when I completed my master's degree, I had a hell of a time researching and writing my dissertation.
Basically I got writers block because I felt lonely.
