It came from Arcosanti in Arizona, a place I've known about way back into the late 1960s and to which I took Jerry sometime after we married. Arcosanti is an amazing place, and something about it touches an "arty" core inside my being. I couldn't possibly tell you the "how" and "why" of Paolo Soleri's Arcosanti and do it justice, so I've borrowedfrom their website <http://www.arcosanti.org/main.html> and trust that you will go there on your own, for it is absolutely fascinating.
Here's what you'll read: "In 1970, the Cosanti Foundation began building Arcosanti, an experimental town in the high desert of Arizona, 70 miles north of metropolitan Phoenix. When complete, Arcosanti will house 5000 people, demonstrating ways to improve urban conditions and lessen our destructive impact on the earth. Its large, compact structures and large-scale solar greenhouses will occupy only 25 acres of a 4060 acre land preserve, keeping the natural countryside in close proximity to urban dwellers.
"Arcosanti is designed according to the concept of arcology (architecture + ecology), developed by Italian architect Paolo Soleri. In an arcology, the built and the living interact as organs would in a highly evolved being. This means many systems work together, with efficient circulation of people and resources, multi-use buildings, and solar orientation for lighting, heating and cooling. In this complex, creative environment, apartments, businesses, production, technology, open space, studios, and educational and cultural events are all accessible, while privacy is paramount in the overall design. Greenhouses provide gardening space for public and private use, and act as solar collectors for winter heat. "
