Richard Buckminster “Bucky” Fuller

born on July 12, 1895, in Milton, Massachusetts,

 Spending much of his youth on Bear Island, in Penobscot Bay off the coast of Maine

Struggled in school

Slide4

Fuller was sent to Milton Academy, in Massachusetts, and after that, began studying at Harvard.

He was expelled from Harvard twice: first for spending all his money partying with a vaudeville troupe, and then, after having been readmitted, for his "irresponsibility and lack of interest." By his own appraisal, he was a non-conforming misfit in the fraternity environment

Slide5

By age 32, Fuller was bankrupt and jobless, living in public, low-income housing in Chicago, Illinois.

In 1922,

Fuller's young daughter Alexandra died from complications from polio and spinal meningitis.

Allegedly, he felt responsible and this caused him to become drunk frequently and to contemplate suicide for a while.

He finally chose to embark on "an experiment, to find what a single individual [could] contribute to changing the world and benefiting all humanity.

Slide11

Geodesic Dome

Although Fuller was not the original inventor, he developed the intrinsic mathematics of the dome, thereby allowing popularization of the idea — for which he received a U.S. patent in 1954

Slide12

The geodesic dome appealed to Fuller because it was extremely strong for its weight, its "

omnitriangulated

" surface provided an inherently stable structure, and because a sphere encloses the greatest volume for the least surface area

The 

Dymaxion

Chronofile

 is Buckminster Fuller's attempt to document his life as completely as possible. He created a very large scrapbook in which he documented his life every 15 minutes from 1920 to 1983.

The scrapbook contains copies of all correspondence, bills, notes, sketches, and clippings from newspapers. The total collection is estimated to be 270 feet (80 m) worth of paper.

This is said to be the most documented human life in history.

Slide18

"There is no energy crisis, only a crisis of ignorance."

Fuller coined to mean "doing more with less“

Buckminster Fuller was one of the first to propagate a systemic worldview, and he explored principles of energy and material efficiency in the fields of architecture, engineering and design. 

He cited François de

Chardenedes

' opinion that petroleum, from the standpoint of its replacement cost out of our current energy "budget" (essentially, the net incoming solar flux), had cost nature "over a million dollars" per U.S. gallon (US$300,000 per

litre) to produce. From this point of view, its use as a transportation fuel by people commuting to work represents a huge net loss compared to their earnings

Buckminsterfullerene

"It is the roundest and most symmetrical large molecule known to man.

Buckministerfullerene

continues to astonish with one amazing property after another. Named after American architect R. Buckminister

Fuller who designed a geodesic dome with the same fundamental symmetry, C60 is the third major form of pure carbon; graphite and diamond are the other two

Carbon Nanotubes

Slide22

Many potential applications have been proposed for carbon

nanotubes

,

including

conductive and high-strength composites; energy storage and energy conversion devices; sensors; field emission displays and radiation sources; hydrogen storage media; and nanometer-sized semiconductor devices, probes, and interconnects.

Some of these applications are now realized in products. Others are demonstrated in early to advanced devices, and one, hydrogen storage, is clouded by controversy.

Nanotube

cost, polydispersity in nanotube type, and limitations in processing and assembly methods are important barriers for some applications of single-walled

nanotubes

Slide23

Applications of Buckytubes

Carbon

nanotubes

have valuable qualities as structural materials. Potential uses include:

Textiles

—CNT can make waterproof and/or tear-resistant fabricsBody armor

—MIT is working on combat jackets that use CNT fibers to stop bullets and to monitor the condition of the wearer.

[1] Cambridge University developed the fibres and licensed a company to make them.

[2]

Concrete

—CNT in concrete increase its tensile strength, and halt

crack propagation

.

[3]

Polyethylene

—

Addint

CNT to polyethylene can increase the polymer's

elastic modulus

by 30%.

Sports equipment

—Stronger and lighter

tennis rackets

,

bicycle

parts,

golf balls

,

golf clubs

, and

baseball bats

.

Space elevator

—CNT are under investigation as possible components of the

tether

up which a space elevator can climb. This requires

tensile strengths

of more than about 70 

GPa

.synthetic muscles: Due to their high contraction/extension ratio given an electric current, CNTs are ideal for synthetic muscle.[4]High tensile strength fibers—Fibers produced with polyvinyl alcohol required 600&nbspJ/g to break.[5] In comparison, the bullet-resistant fiber Kevlar fails at 27–33 J/g.Bridges—CNT may be able to replace steel in suspension and other bridges.Flywheels—The high strength/weight ratio enables very high rotational speeds.Fire protection—Thin layers of buckypaper can significantly improve fire resistance due to the efficient reflection of heat by the dense, compact layer of CNT or carbon fibers.[6]
