Stanford Torus vs Bernal Sphere

The study which produced the Stanford Torus is available on the web
here:

I don't know that I ever got to see the study which produced the Bernal
Sphere. I think everything I know about it comes out of The High
Frontier. I know that the 4 million ton figure I quoted came from that
book.

all I can really do is compare published and peer-reviewed studies ...
The published figures of 10 million tons mass vs. 4 million tons would
seem to imply about a 2:1 ratio.

Mike, can you aim us at your "published and peer-reviewed studies"? I
don't doubt you; I just love to document these things for other
discussions on other lists. Thanks...
