During my last visit to Singapore we visited the latest “place of interest” built in the city, Gardens by the Bay, which was opened to the public last June. It is a botanic garden with artificial trees called “supertrees” of up to 50 meters tall that are powered by solar energy.
In total there are 18 supertrees with photovoltaic panels and that are also able to accumulate rain water thanks to their conical shape. They are not arcologies yet because they can’t host human life, but when you go up the trees and walk from one to another you can’t avoid thinking that they look like structures generated by rendering software used in science fiction movies.
