What of a buckytube one meter in radius? Or merely one millimeter in

was using the correct equation for stress on a diametral section.

I would love to see such figures.

You are in luck! I had completely forgotten that Robert A. Freitas Jr
covers this topic in the book Nanomedicine, "9.5.3.3 Buoyant Nanoballoons"
which is online at this URL:

Thanks to Freitas for pointing this out.

Wow!
Thanks for finding that.
dang guy is at least 7 yrs ahead of my brain huh?
