Geodesic dome "transmigration" method is based so specifically on dome design that only fixed numbers of people can take part in the process at each deliberation stage. Many geodesic domes are among the largest clear-span structures in the world. According to the Buckminster Fuller Institute in 2010, the world's 10 largest geodesic domes by diameter are: One other large dome in Venezuela was missed on the original Fuller Institute list, while two others built later are also now in the top 10. Currently, several geodesic domes are larger than 113 m in diameter. Geodesic dome A geodesic dome is a hemispherical thin-shell
Geodesic dome A 30-foot wood and plastic geodesic dome was lifted and carried by helicopter at 50 knots without damage, leading to the manufacture of a standard magnesium dome by Magnesium Products of Milwaukee. Tests included assembly practices in which previously untrained Marines were able to assemble a 30-foot magnesium dome in 135 minutes, helicopter lifts off aircraft carriers, and a durability test in which an anchored dome successfully withstood without damage, a day-long propeller blast from the twin 3,000 horsepower engines of an anchored airplane. The dome was introduced to a wider audience as a pavilion for the 1964 World's Fair
