Was there anything in particular that you specifically disagree with Van Allen on, either in my summary or the first (free) chapter of his book?
I shared the link that you sent me with him on Discord, and he told me that he’s seen it before.
He also said that the link that you sent still doesn’t specify the structure in enough detail, as far as he can see, and that it doesn’t really matter.
Like, I noticed that O’Neill proposed: 1. retrieving the cylinder materials from the Moon and 2. setting up either a Rotary Pellet Launcher or a Transport Linear Accelerator for retrieving materials from the Moon to make the construction cheaper.
I agree that he didn’t address this possibility in the book, but I don’t fully understand your criticism regarding the steel structure math.
You might be more knowledgeable on this topic than I am, so I’m also wondering if you know of any sources where O’Neill gave a more specific description of what he was thinking about?
For example, I’m trying to figure out what O’Neill proposed for the thickness of the original cylinder hull.
I can’t find it on Wikipedia or in the link that you sent me, and I think this is a huge deal because the exact dimension of the hull thickness can greatly change the amount of materials that are required for building the cylinder.
