I just want to highlight what's important about this design: IT'S FRAMELESS This drastically brings down the costs. There are still disadvantages, of course -- the inflexible shape and lack of large, flat, vertical surfaces is a problem for most applications -- but the dome is now so much cheaper that, in some niches, they're worth a second look. I can well imagine, for instance, mass-produced geodesic haybarns based on this design.
