Arcology, in simplest terms, is "the fusion of architecture with ecology." Designed by Paolo Soleri, Arcosanti is located in the high desert of northern Arizona. Begun in 1970 as an "urban laboratory," it can house 7000 people while occupying only 25 acres of a 4,060 acre preserve. The site promotes this alternative use of space and seeks to educate people on arcology and Soleri via a virtual tour, various essays and e-mail links to some of the residents. The Arcosanti web site is the next best thing to being there.
