Could you help me out al little further? (here's the idea elaborated) This structure would be just that, only devised to demonstrate the possible height. It would not be a building, or have an elevator or door. It would just be the least amount of required materials to achieve maximum tall. Can I have some answers on how high and how minimal of a structure could be built. If I were to build as far as is humanly possible, how high could I go with the perfect circumference (as minimal as possible yet strong enough to hold up).
