The segments themselves are 100% modular and you could tile an US state with them. The main problem is engineering: the whole thing needs to behave like a single object, turning 360 degrees and moving between horizon and zenith (horizontal and vertical), with a minimum of mechanical flexure. And also resisting wind load. In essence, it's a lightweight building that has to move freely, and this one won't get bigger.
