And by the way, using helium instead of air gives about 250% increase in lift. 600% for hydrogen .
The benefit of the geodesic structure is stability and strength. The structure will not be "closed" and filled with pressurized gases. It would be only air with openings above and below. Hence, I don't see any need to have an amorphous structure (such as a typical balloon).

Anyways, Hydrogen is dangerous and Helium is in short supply.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
