Would serving as a dam and supplying water to its 55,000 residents The aims of the project are to reach a nautical mile in height while "not using concrete, orthogonal grids, traditional systems, mortars, cranes." If built, the tower would reach 1,852 metres (6,076 ft). ĭesigned by architect Omero Marchetti as part of his proposed "ethic city" concept. "De Nederlandse Berg", Dutch for "The Dutch Mountain" is a proposal for an artificial mountain by Thijs Zonneveld. Tourism, leisure, commercial and wind generation If built, it will be the largest man-made structure on Earth. The structure would be approximately 14 times as high as the Great Pyramid of Giza, and would house 750,000 people. The Shimizu Mega-City Pyramid is a proposed project for construction of a massive pyramid over Tokyo Bay in Japan. Residential, commercial, retail, and leisure real estate Residential, commercial, and retail real estateĭesigned by American architect Eugene Tsui in 1991 Would accommodate five hundred thousand to one million inhabitants Residential, commercial, retail real estate, as well as heavy industry The cost would be around ¥3 quadrillion ($22 trillion). Would house roughly 30 million people and take 100–150 years to build. It has a long (1000–1500 km) vacuum tube, levitated via strong currents in superconducting cables

The structure would be free standing and actively guyed over its base. Tourism, communications, wind generation, andĪ sub-orbital or mini version.
The Launch loop is a concept that has been proposed for the purposes of orbital launch. Multiple tethers can be connected from orbital ring to the ground enabling mass-transport to space. A motorized platform is placed on the cable that runs in the opposite direction at the speed that makes the ring structure become stationary relative to the ground at much lower attitude compare to space elevator which has to maintain its center of mass around geostationary orbit.
The Orbital ring is a concept of an artificial ring shaped cable placed around Earth and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. Space tourism/ exploration/ colonization, Space manufacturing, Telecommunication, and Space-based solar power Space tourism, space exploration, and space colonizationĪn extraordinarily long cable, anchored on or near the equator, held up by the rotation of the Earth.ġ60 km (99 mi) to 80 km (50 mi) of minimal height This list is incomplete you can help by adding missing items.
