Some of the common elements to all projects are on-site food and energy production; on-site rain and grey water recycling and re-use; on-site sewage treatment and re-use; on-site solid waste collection, recycling and re-use; mass public transit systems; roof-top gardens; solar architecture; mixed land uses; road infrastructure for personal transportation devices (e.g. “Segway” vehicles, electric skateboards, bicycles, GPS-guided mini-autos); and physical and policy measures to adapt to rising sea levels (where necessary). All projects also put emphasis on the aesthetic qualities of public spaces.
