Modifications to Puxin 10m3 design for continuous feed digestion of food wastes

Legacy issues from the time when most people assumed biodigesters were a rural technology best fed with animal manures still plague digester design and operation.
A case in point is the current design of the simplified 10m3 Chinese "Puxin" digester.
Plans for the digester, which is increasingly used in urban and suburban areas where food waste is the most available and preferred feedstock,  still call for a vertical feedpipe, despite the fact that food wastes are usually very buoyant and have a hard time going down the "throat" of the domestic dragon.

Update on Jordan Trips

 Update on Jordan Project

In January of 2017, after extensive team and relationship building in preparation for the initiative, Solar CITIES president T.H. Culhane and graduate student Enas AbdelRahman left the Arava Institute of the Environment, where they were working on a biogas refrigeration project, by bus, traveling overland to Jericho to make the King Hussein/Allenby Bridge crossing from Israel to Jordan.  They made the trip using Culhane’s personal money.

Solar CITIES first Puxin Digester in Florida.

Solar CITIES is completing Florida's first community biodigester at the Bishop family farm Rosebud Sustainability Education project. This is the first of three and will be used as a proof of concept and training ground for the entire south, using biogas as the central technology that will include hydroponics, native plants, and Solar energy. USF Patel College students and faculty have been involved and it is hoped that the site will become a living laboratory for best practices in Sustainable Development that will influence the entire region.

Intro Slide for 3 minute update

"While Nobody  expects the Spanish Inquisition, I expect or at least hope you may want to hear my “what’s new with  Solar CITIES”  3 minute exposition in which I would like to reveal our three chief weapons against such diverse elements as poverty indoor air pollution, deforestation and climate change.

Weapon #1:

The right to a sustainable city... and how to get there

The use of the term “sustainable cities” forces us to ask the question “what are we trying to sustain?”. These days “sustainability” has become a buzzword for some hazy notion of “ecologically friendly”.  But “sustainable” merely means “lasting”.  Not everything that we sustain is a good thing, and in many cities, for example, crime has become self-perpetuating and hence “sustainable”. Are cities making people happy so that they will stay and contribute?
