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)

On second thought, this arrangement may prove sufficient for single stead stability (when moving ?), while multiple ones are supposed to connect and form a semi-submersible platform.--Jesrad 08:51, 15 September 2008 (UTC)
