Domes are the only man-made structure that become proportionally stronger as they increase in size (if the frequency is increased). One or two people can erect the basic structure very quickly, from lightweight pieces. Domes are aerodynamic, withstanding considerable wind loads, such as those created by hurricanes.
This dome is covered with an elastomeric coating that is inexpensive and waterproof.
