I have been looking into this over the last couple of years and have been dismayed by costs and complexity of hubs. This is the best one I have seen and even my carpentry skills (none whatsoever) would be up to this. I will be having a go once my solar dehydrator (plans per permies) is constructed.

Domes are a great design if you are prepared for the high air mass volume to sqft print.
Pagoda springs where the growing spaces co is located has hydro-thermal springs in the area so they have easy to tap winter heat.
I do not know of any other domes that are running year round.
Of the domes I have read about in Alaska, Alberta, WI, etc they all seem to be season extension greenhouses, not year round operations.
AFAIK, no university working on cold climate growing spaces has advocated for a geodesic dome design... (Yukon, Alaska, Minnesota et. al.)
