When reading about this city, many other failed projects come to mind. We shouldn't forget that there was not one successful city that had been founded will the goal of Utopia that is still functioning on those principles. New Harmony, Indiana and even Radburn New Jersey come to mind. Radburn had gone bankrupt before the city could be completed (a very watered-down version of a Garden City), and New Harmony erupted in chaos.
Apparently the creators of this new green city have not down any research into the (un)success of creating new towns that are structured on completely new ideas. I just say why not focus on improving the cities and towns that exist today, before creating entirely new ones?
