They caught on for covering large areas (stadiums, aircraft hangars, etc.) but they don't really make sense on what you might call the "human scale", roughly 3 to 10 meters, say. At human scale wood and metal are strong and light enough that you don't really need geodesic designs. (Wood and metal are geodesic already, just at small scale, eh?) - - - - A slight tangent, but check out the demo carbon-fiber strut work here: https://dragonplate.com/carbon-fiber-truss https://dragonplate.com/carbon-fiber-truss > The truss measures 8 feet long, 16 inches high with a depth of 12 inches. This is just one of many structures that could be easily built using our square tubes and gussets. Weighing in at just 14lbs., the truss is light enough for a six year old child to lift and carry! They show that: a cute kid holding it up, no problem. Then they load it up. > ...we loaded it with 35 80lb. bags of concrete mixture, totaling a whopping weight of 2800 lbs.! Again, we saw no signs of weakness or flexing. We would have put on more bags, but we just couldn't stack them any higher! We could cover whole cities with domes...
