Actually, my version is around the size of 7-8 football fields with enough room for independent sanitation process and filtration, room for farming essential agriculture, a dynamic canopy for solar power, fresh water filteration for farming and consumption and an enormous space for self storage and loading. Most dynamics considered for a city or small community scaled down.

Ultimately, islands like these are grouped in a community.

I would like to get involved in the conceptual idea of this.
