The Lean Linear City is Soleri's latest incarnation of Arcology. The idea is that as part of the Lean Alternative a program of global sustainable development would be commenced by a consortium of internationally affiliated groups. These groups would work to create a ecosystem of ventures to create the design, technologies and related services and skill sets to not only build alternative human habitats like Lean Linear City but also create the economy that will sustain these habitats and enable finance further development.
