Geodesic Dome




Developed by Buckminster Fuller in 1954, the Geodesic Dome was promoted as the world's strongest, most economical, lightweight structure. The ingenious engineering of the geodesic dome allows it to cover a wide stretch of space without using internal supports. The geodesic dome design was patented in 1965.


Geodesic Domes are ideal for emergency housing and mobile shelters such as military camps. However, the innovative geodesic shape has been adopted for elegant, upscale housing.




A geodesic dome is a sphere-like structure composed of a complex network of triangles. The triangles create a self-bracing framework that gives structural strength while using a minimum of material. The term geodesic is from Latin, meaning earth dividing. A geodesic line is the shortest distance between any two points on a sphere.


The the idea of combining triangles with the arch was pioneered by German engineer Dr. Walther Bauersfeld when he designed the world's first projection planetarium, built in Jena, Germany in 1922. However, it was Buckminster Fuller ("Bucky") who conceived the concept of geodesic dome homes. Fuller's first patent for a geodesic dome was issued in 1954.

 

Geodesic domes are efficient, inexpensive, and durable. For $350, an African family can be housed in a corrugated metal dome. Plastic and fiberglass domes used for sensitive radar equipment in Arctic regions and for weather stations around the world. Geodesic domes are also used for emergency shelter and mobile military housing
