Stability of split version
With the height that you show I don't think just having heavy stuff in the bottom of the sphere will give you enough stability. I think even wind could tip it. Maybe a hanging ballast would be the way to go. Vincecate 22:48, 14 September 2008 (UTC)
- I figured I'd add a ballast on the outside, but then I realized the top half was maybe 2-5% of the total mass, and the truss 10% max. The center of mass stays inside the sphere easily, just having the bank of batteries at the bottom of it, plus scrap metal, would keep it upright.
- Of course that means landing aircraft there would be impractical or maybe even impossible... On the other hand, a hanging ballast could help with dynamic stability, if not static stability. I'll look into it.--Jesrad 08:47, 15 September 2008 (UTC)
