Solar C³ities is an international non-profit educational organization with the intention of providing an open-source virtual Hackspace for "Biogas Innoventors and Practitioners" and training for all  those researching, developing and deploying sustainable solutions for flourishing societies.

With microbial transformation of food and toilet wastes and other organic residuals as the center piece -- things which everybody everywhere has in abundance,  things that formerly were considered "problems" and sources of "dis-ease" -- all other technologies can be more easily placed around the eternal fire that results from  this natural hearth.  Most other energy systems are intermittent. Biodigestion is a bacterial constant, producing just enough baseline energy and nutrient rich fertilizer to allow homes and communities to relax and integrate all of the other solutions for sustainable in a meaningful way, enabling the flowering of true solar cities around the world.
