Jim,

Thanks for the link. I responded to Spaceman earlier and find with your
help that nanotubes may actually work like large scale balloons. Spaceman I
take back my earlier statement.

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.
