Re:why can't this be built in full gravity? (Score 1)

Theoretically, the design would work, but there are so many better ways. The three simplest points are: 1: The structure would be under extreme sheer stress at the focal point. (The idea behind most buildings construction is to spread the load so one can get away with less expensive materials and a lesser amount of them as well). An anology that would work is using a cheap lug wrench to break loose lugs nuts on a car. That thing bends before you break that nut loose. Imagine the foundation doing that. 2. Okay, say the frame holds up. What's to keep the small, buried end from busting up through the porous, lightweight, psuedo-volcanic rock of which I assume the moon is made? I didn't see any bracing there on that design. I guess we're supposed to assume.... (This point is also valid if you believe that the moon is made of one of those really stinky, expensive types of cheeses.) 3. Fine, the frame holds, and the stone/cheese also holds. That hotel looks to be just stuck in the rock, what's to keep it from rocking as people move? Seeing as how 10-15 people weigh about a ton, if you have 10-15 thousand people staying there, you could have an unbalanced wieght of about a thousand tons, which would unbalance most structures that are anchored down. Due to all the other points made here, a moon hotel is unfeasible at this time. Aside from that, this design is awful.
