The geodesic dome
Fuller was most famous for his lattice shell structures - geodesic domes, which have been used as parts of military radar stations, civic buildings, environmental protest camps and exhibition attractions. However, the original design came from Dr. Walther Bauersfeld. Chapter 3 of Fuller's Book
Critical Path states:
"... I found a similar situation to be existent in World War II. As head mechanical engineer of the U.S.A. Board of Economic Warfare I had available to me copies of any so-called intercepts I wanted. Those were transcriptions of censor-listened-to intercontinental telephone conversations, along with letters and cables that were opened by the censor and often deciphered, and so forth. As a student of patents I asked for and received all the intercept information relating to strategic patents held by both our enemies and our own big corporations ..."
An examination of the geodesic design by Bauersfeld for the Zeiss Planetarium, built some 20 years prior to Fuller's work, reveals that Fuller's Geodesic Dome patent (U.S. 2,682,235) follows the same methodology as Bauersfeld's design.
Their construction is based on extending some basic principles to build simple "tensegrity" structures (tetrahedron, octahedron, and the closest packing of spheres), making them lightweight and stable. The patent for geodesic domes was awarded during 1954, part of Fuller's exploration of nature's constructing principles to find design solutions. The Fuller Dome is referenced in the Hugo Award-winning novel
Stand on Zanzibar by John Brunner, in which a geodesic dome is said to cover the entire island of Manhattan, and it floats on air due to the hot-air balloon effect of the large air-mass under the dome (and perhaps its construction of lightweight materials).

Transportation
In the 1930s, Fuller designed and built prototypes of what he hoped would be a safer, aerodynamic car, which he called the Dymaxion. ("Dymaxion" is said to be a syllabic abbreviation of
dynamic maximum tension, or possibly of
dynamic maximum ion.) Fuller worked with professional colleagues for three years beginning in 1932 on a design idea Fuller had derived from aircraft technologies. The three prototype cars were different from anything being sold at the time. They had three wheels: two front drive wheels and one rear, steered wheel. The engine was in the rear, and the chassis and body were original designs. The aerodynamic, somewhat tear-shaped body was large enough to seat eleven people and was about long, resembling a blend of a light aircraft (without wings) and a Volkswagen van of 1950s vintage. All three prototypes were essentially a mini-bus, and its concept long predated the Volkswagen Type 2 mini-bus conceived in 1947 by Ben Pon.
Despite its length, and due to its three-wheel design, the Dymaxion turned on a small radius and could easily be parked in a tight space. The prototypes were efficient in fuel consumption for their day, traveling about 30 miles per gallon. Fuller contributed a great deal of his own money to the project, in addition to funds from one of his professional collaborators. An industrial investor was also very interested in the concept. Fuller anticipated the cars could travel on an open highway safely at up to about 160 km/h (100 miles per hour), but, in practise, they were difficult to control and steer above 80 km/h (50 mph). Investors backed out and research ended after one of the prototypes was involved in a high-profile collision that resulted in a fatality. In 2007,
Time Magazine reported on the Dymaxion as one of the "50 worst cars of all time".
In 1943, industrialist Henry J. Kaiser asked Fuller to develop a prototype for a smaller car, but Fuller's five-seater design was never developed further.
Housing
Fuller's energy-efficient and inexpensive Dymaxion House garnered much interest, but has never been produced. Here the term "Dymaxion" is used in effect to signify a "radically strong and light tensegrity structure". One of Fuller's Dymaxion Houses is on display as a permanent exhibit at The Henry Ford in Dearborn, Michigan. Designed and developed during the mid-1940s, this prototype is a round structure (not a dome), shaped something like the flattened "bell" of certain jellyfish. It has several innovative features, including revolving dresser drawers, and a fine-mist shower that reduces water consumption. According to Fuller biographer Steve Crooks, the house was designed to be delivered in two cylindrical packages, with interior color panels available at local dealers. A circular structure at the top of the house was designed to rotate around a central mast to use natural winds for cooling and air circulation.
Conceived nearly two decades before, and developed in Wichita, Kansas, the house was designed to be lightweight and adapted to windy climates. It was to be inexpensive to produce and purchase, and assembled easily. It was to be produced using factories, workers and technologies that had produced World War II aircraft. It was ultramodern-looking at the time, built of metal, and sheathed in polished aluminum. The basic model enclosed 90 m² (1000 square feet) of floor area. Due to publicity, there were many orders during the early Post-War years, but the company that Fuller and others had formed to produce the houses failed due to management problems.
During 1969, Fuller began the Otisco Project, named after its location in Otisco, New York. The project developed and demonstrated concrete spray technology used in conjunction with mesh covered wireforms as a viable means of producing large scale, load bearing spanning structures built on site without the use of pouring molds, other adjacent surfaces or hoisting.
The initial construction method used a circular concrete footing in which anchor posts were set. Tubes cut to length and with ends flattened were then bolted together to form a duodeca-rhombicahedron (22 sided hemisphere) geodesic structure with spans ranging to . The form was then draped with layers of ¼-inch wire mesh attached by twist ties. Concrete was then sprayed onto the structure, building up a solid layer which, when cured, would support additional concrete to be added by a variety of tradition means. Fuller referred to these buildings as monolithic ferroconcrete geodesic domes. The tubular frame form proved too problematic when it came to setting windows and doors, and was abandoned. The second method used iron rebar set vertically in the concrete footing and then bent inward and welded in place to create the dome's wireform structure and performed satisfactorily. Domes up to three stories tall built with this method proved to be remarkably strong. Other shapes such as cones, pyramids and arches proved equally adaptable.
The project was enabled by a grant underwritten by Syracuse University and sponsored by US Steel (rebar), the Johnson Wire Corp, (mesh) and Portland Cement Company (concrete). The ability to build large complex load bearing concrete spanning structures in free space would open many possibilities in architecture, and is considered as one of Fuller's greatest contributions.
Alternative map projection
Fuller also designed an alternative projection map, called the Dymaxion map. This was designed to show Earth's continents with minimum distortion when projected or printed on a flat surface.
