Imagine a bubble that can accommodate 4000 residents and 1000 visitors. This 500m diameter bubble could house all the elements of a city: shops, hotels, offices and housing.

A 20 billion euro project, but it will be necessary to wait until 2030 for the technology to allow its construction, specify the visionary engineers of Shimizu.
