Megastructure
A megastructure (or macrostructure) is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures. Most megastructure designs could not be constructed with today's level of industrial technology. This makes their design examples of exploratory engineering, speculative (or exploratory) engineering. Those that could be constructed tend to qualify as megaprojects. Examples of megaprojects are the Zuiderzee Works in the Netherlands and Burj Khalifa in Dubai, the UAE. Megastructure (planning concept), Megastructures are also an architectural concept popularized in the 1960s where a city could be encased in a single building, or a relatively small number of buildings interconnected. Such arcology concepts are popular in sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megastructure (planning Concept)
Megastructure is an architectural and urban concept of the post-war, post-war era, which envisions a city or an urban form that could be encased in a massive single human-made structure or a relatively small number of interconnected structures. In a megastructural project, orders and hierarchies are created with large and permanent structures supporting small and transitional ones. According to John W. Cook and Heinrich Klotz, the lexical meaning of megastructure is an over-scaled, colossal, multi-unit architectural mass. The post-war megastructure movements led by avant-garde architectural groups such as Metabolism (architecture), Metabolists and Archigram regarded megastructure as an instrument to solve issues of urban disorder. Megastructure was once the dominant tendency in architecture of the 1960s, which resulted in numerous radical architectural proposals and a few built projects.

Megascale Engineering
Megascale engineering (or macro-engineering) is a form of exploratory engineering concerned with the construction of structures on an enormous scale. Typically these structures are at least in length—in other words, at least one megameter, hence the name. Such large-scale structures are termed megastructures. In addition to large-scale structures, megascale engineering is also defined as including the transformation of entire planets into a human-habitable environment, a process known as terraforming or planetary engineering. This might also include transformation of the surface conditions, changes in the planetary orbit, and structures in orbit intended to modify the energy balance. Astroengineering is the extension of ''megascale engineering'' to megastructures on a stellar scale or larger, such as Dyson spheres, Ringworlds, and Alderson disks. Several megascale structure concepts such as Dyson spheres, Dyson swarms, and Matrioshka brains would likely be built upon sp ...

Metabolist Movement
was a post-war Japanese Biomimetic architecture, biomimetic architectural movement that fused ideas about architectural Megastructure (planning concept), megastructures with those of organic biological growth. It had its first international exposure during Congrès Internationaux d'Architecture Moderne, CIAM's 1959 meeting and its ideas were tentatively tested by students from Kenzo Tange's Massachusetts Institute of Technology, MIT studio. During the preparation for the 1960 Tokyo World Design Conference a group of young architects and designers, including Kiyonori Kikutake, Kisho Kurokawa and Fumihiko Maki prepared the publication of the Metabolism manifesto. They were influenced by a wide variety of sources including Marxism, Marxist theories and biological processes. Their manifesto was a series of four essays entitled: Ocean City, Space City, Towards Group Form, and Material and Man, and it also included designs for vast cities that floated on the oceans and plug-in capsule ...

Astroengineering
Engineering on an astronomical scale, or astronomical engineering, ''i.e.'', engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering. On the Kardashev scale, Type II and Type III civilizations can harness energy on the required scale. Kardashev, Nikolai.On the Inevitability and the Possible Structures of Supercivilizations, The search for extraterrestrial life: Recent developments; Proceedings of the Symposium, Boston, MA, June 18–21, 1984 (A86-38126 17-88). Dordrecht, D. Reidel Publishing Co., 1985, p. 497–504. This can allow them to construct megastructures.

Yona Friedman
Yona Friedman (5 June 1923 – 20 February 2020) was a Hungarian-born French architect, urban planner and designer. He was influential in the late 1950s and early 1960s, best known for his theory of "mobile architecture". In 2018, on his 95th birthday, he was awarded the Austrian Frederick Kiesler Prize for Architecture and the Arts. Early years Born in Budapest, Hungary, in 1923, into an ethnic Jewish family, which posed him problems because of the anti-Semitic quota laws at universities, Friedman survived the Second World War by escaping the Nazi roundups of Jews, and he lived for about a decade in the city of Haifa in Israel before moving permanently to Paris in 1957. He became a French citizen in 1966. In 1956, at the Xth International Congress of Modern Architecture in Dubrovnik, his "Manifeste de l'architecture mobile" contributed to question definitely the daring will planning to architectural design and urbanism. It was during that conference, and thanks especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendezvous With Rama
''Rendezvous with Rama'' is a 1973 science fiction novel by British writer Arthur C. Clarke. Set in the 2130s, the story involves a cylindrical alien starship that enters the Solar System. The story is told from the point of view of a group of human explorers who intercept the ship in an attempt to unlock its mysteries. The novel won both the Hugo and Nebula awards upon its release, and is regarded as one of the cornerstones in Clarke's bibliography. The concept was later extended with several sequels, written by Clarke and Gentry Lee. Plot An asteroid strikes Italy in 2077, prompting the creation of the Spaceguard system to track potentially hazardous objects in space. In 2131, Spaceguard detects an interstellar object entering the Solar System, designating it "31/439" before naming it Rama after the Hindu god. A space probe reveals that Rama is a perfectly smooth cylinder long and in diameter, indicating that it was constructed by intelligent beings. ''Endeavour'' is ...

Archigram
Archigram was an avant-garde British architectural group whose unbuilt projects and media-savvy provocations "spawned the most influential architectural movement of the 1960's," according to Princeton Architectural Press study ''Archigram'' (1999). Neofuturistic, anti-heroic, and pro-consumerist, the group drew inspiration from technology in order to create a new reality that was expressed through hypothetical projects, i.e., its buildings were never built, although the group did produce what the architectural historian Charles Jencks called "a series of monumental objects (one hesitates in calling them buildings since most of them moved, grew, flew, walked, burrowed or just sank under the water." The works of Archigram had a neofuturistic slant, influenced by Antonio Sant'Elia's works. Buckminster Fuller and Yona Friedman were also important sources of inspiration. "Their attitude was closely tied to the technocratic ideology of the American designer Buckminster Fuller," ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trans-Global Highway
A fixed link or fixed crossing is a permanent, unbroken road or railroad, rail connection across water that uses some combination of bridges, tunnels, and causeways and does not involve intermittent connections such as drawbridges or ferry, ferries. A bridge–tunnel combination is commonly used for major fixed links. This is a list of proposed and actual transport links between continents and to offshore islands. See also list of bridge–tunnels for another list of fixed links including links across rivers, bays and lakes. History Cosmopolitan Railway In 1890 William Gilpin (governor), William Gilpin first proposed to connect all the continents by land via the Cosmopolitan Railway. Significant elements of that proposal, such as the English Channel Tunnel, have been constructed since that era. However, the improvement of the global shipping industry and advent of international air travel has reduced the demand for many intercontinental land connections. Europe English Channel T ...

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Nine (tensegrity Sphere)
Cloud Nine is the name Buckminster Fuller gave to his proposed airborne habitats created from giant geodesic spheres, which might be made to levitate by slightly heating the air inside above the ambient temperature. Geodesic spheres become stronger (and relative to the volume enclosed, lighter) as they become bigger, because of how they distribute stress over their surfaces. As a sphere gets bigger, the volume it encloses grows much faster than the mass of the enclosing structure itself. Fuller suggested that the mass of a mile-wide geodesic sphere would be negligible compared to the mass of the air trapped within it. He suggested that if the air inside such a sphere were heated even by one degree higher than the ambient temperature of its surroundings, the sphere could become airborne. He calculated that such a balloon could lift a considerable mass, and hence that 'mini-cities' or airborne towns of thousands of people could be built in this way. A Cloud Nine could be tether ...

Strait Of Gibraltar
The Strait of Gibraltar is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Europe from Africa. The two continents are separated by 7.7 nautical miles (14.2 kilometers, 8.9 miles) at its narrowest point. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between . The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar. Under the United Nations Convention on the Law of the Sea, foreign vessels and aircraft have the freedom of navigation and overflight to cross the strait of Gibraltar transit passage, in case of continuous transit. Names and etymology The name comes from the Rock of Gibraltar, which in turn originates from the Arabic (meaning "Tariq's Mount"), named after Tariq ibn Ziyad. It is also known as the Straits of Gibraltar, the Gut (coastal geography), Gut of Gibraltar (although this is mostly archaic), the STROG (STRait Of ...
