Talk:Air-formed domes

Closely related page: http://openfarmtech.org/wiki/Monolithic_Dome, perhaps we can merge them. Basic difference: binishells= concrete first, then inflate monolithic= inflate, then "shotcrete" --Rasmus

Binishells seem much cheaper. I have no idea why. --Conor 13:44, 26 February 2011 (PST)

Doesn't make obvious sense. Monolithic has brought down the cost of the ecoshell to bare bones materials cost. And now with basalt fibers one of the significant cost items (steel rebar) is eliminated. The inflatable form can be reused 100 times in both concepts. --Rasmus

Conor, I just saw the Youtube link you posted on the page Air-formed_domes. The Binishell appears to require not only two membranes (a major cost item, even when reusable) but also a particular kind of steel spring.
