10 fantastic space megaprojects Bashny.Net

If the mega-projects, which will be discussed in this review, ever be realized, they will be a great achievement of mankind. After all, in practice, at one point, even the most fantastic embodied desires.





Space elevator
Space Elevator proposed to build to transport material from the surface of the Earth into orbit. It offers a lot of options, but the most realistic look at where the goods are displayed on the geostationary orbit near the equator. Modern technology does not allow us to construct a lift, but the researchers suggest that the advanced design of carbon nanotubes can withstand the load.

Orbital ring
Orbital ring - is, in fact, a type of a space elevator, it differs in that revolves around the Earth orbit (rotating cable is placed into low Earth orbit over the equator). Within this ring may move along the cable using superconducting magnets. Also orbital ring stretched to the Earth a number of space elevators made from cables with high tensile strength.

Galo
The first time the colossal structure of "Halo" was described in the novel, science fiction writer Larry Niven. It is a giant (from thousands to hundreds of millions of kilometers) metal rings in space. On the inside of the ring are air, water, plants and animals. Huge walls on the sides of the internal structure as well as the centrifugal force produced by the rotation of the ring, to prevent leakage of the atmosphere into space. The outer surface of the dot dock and windows. This suggests that part of the ring structure is hollow and is used for maintenance and energy production.

Globe Cassus
Globe Cassus - art project of the Swiss architect and futurist Christian Valdfogelya. According to this concept it is supposed to use the entire mass of earth to build instead giant hollow object ecosphere on its inner surface. As a result, living surface that is suitable for human habitation, millions of times have increased. Sunlight will enter through two huge windows, and gravity will be created due to the centrifugal effect. Ecosphere will be limited to the equatorial zone, while the tropical area of ​​low gravity and tenuous atmosphere would be suitable only for plantations. The polar regions will have no gravity, no atmosphere, and therefore will be used for the storage of raw materials and production processes.

Topopolis

Topopolis - is essentially a huge habitable tube, which is due to the rotation of the force of gravity has on the inner surface. Such a tubular structure can be several times "twisted" noose around the star in a torus knot. The concept was invented by Pat Gyunkelem Larry Niven and mentioned in the work "More than worlds." Topopolis sometimes called space spaghetti. Length of habitable cylinders - hundreds of millions of kilometers and a diameter of several kilometers.

Star engine
Star Motors - a kind of hypothetical megastructures that use radiation of the star to generate useful energy. Some embodiments of this energy is used for propulsion, speeding star and its entire system in a given direction.

Brain matryoshka
This structure consists of one or more of the Dyson spheres (spherical shell the size of the radius of the planetary orbits with the star in the center), built around the star, and nested one inside the other. A significant portion of these envelopes will consist of nano-sized computers. Dyson shell will absorb the energy radiated on its inner surface, to use it to power their computer systems, and then re-radiate energy to the outside. The idea mozga- dolls does not violate any of the presently known laws of physics, though its scale simply staggering.

Dyson Sphere
Dyson Sphere - hypothetical mega structure, first described by Freeman Dyson. This "area" should be a system of orbiting solar power satellites, which completely cover the star and will pick up most of the energy emitted by the star. Also Dyson sphere can be a giant spherical shell that cover the entire star and a good half of it, and in which people can live.

Alderson Drive
Alderson Drive (named after its inventor, Dan Alderson) is an artificial astronomical Megastructure, like rings Niven or Dyson sphere. Disc thickness of several thousand kilometers will have a radius approximately equal to the orbit of Jupiter. The star will be in the center of the disc, and the habitable zone - in the middle of the structure. The theoretical weight of the disc is greater than the mass of the sun. It will not be day and night, and the whole world will be submerged in a perpetual twilight.

World-ring
This is an artificial ring with a radius approximately equal to the radius of Earth's orbit. The star is in the center of the ring that rotates to provide artificial gravity. The weight of this ring is estimated to be the total mass of all the planets in the solar system. If such a structure is built, it will be able to provide people with a huge living surface on its inner side.
