Buckminster Fuller wanted his dome houses to be cheap, quickly constructed, and portable. Yes, your house was supposed to be able to be picked up with a helicopter and dropped off somewhere else! The Marines experimented with it in the 60's. There are pictures of domes being flown around.
My purpose for building domes is the same as Bucky's: to save humanity from extinction. We are currently building houses the same way as we did thousands of years ago. Bucky said we would adopt his new technologies only when it was absolutely necessary. Well, the time has arrived. Here is why YOU should be living in a dome:
1) They use far less material than a square building
2) They are much stronger, domes have withstood hurricanes and tornadoes, even a nuclear blast
3) They use less energy, the oft quoted amount is 30% less, but it goes up as the dome gets bigger
I am submitting this as part of the "Win A Home Fabricator" contest. If I had had one when this started, it would have shaved days off of construction and lots of frustration. My next dome will be made out of bamboo, and hopefully use home fabricated vertices (the connectors between the wooden struts.) So if you like this Instructable, please rate it highly so I can make a better dome next time, and work toward that goal of saving humanity from itself.
