I appreciate the welcome.
Please don’t spend too much time trying to understand the HyperCubes because they are not explained in those pages, they will be when we get our website online again. For now, consider them as being balloons with a framework giving them the shape of a cube. Also assume that the mass of the framework would have originally been the mass of a gondola in a traditional balloon. One more point; we say that the SpaceShaft shows rigid properties because the HyperCubes framework is made to be assembled in such a way that when stacked could be compared to a scaffolding system or an antenna that has within the structure balloons that make it buoyant.
And although Old Cracker is very funny it will be nice to name you with a a more humane name 🙂 Cheers
