[16][17] Several concepts were studied, with sizes ranging from 1,000 to 10,000,000 people. In Earth orbit, this amounts to 1400 watts of power per square meter. Nitrogen may also be available in unknown quantities on certain other bodies in the outer solar system. O'Neill cylinder: "Island Three", an even larger design (3.2 km radius and 32 km long). [6][full citation needed], The optimal habitat orbits are still debated, and so orbital stationkeeping is probably a commercial issue. Surely if humanity is capable of building these mega structures then we presumably also managed to end poverty and such. Since then, many variations of this idea have been proposed for space stations and habitats, such as the von Braun Wheel, the O’Neill Cylinder, and the Stanford Torus. I’ll be posting an updated treatment for my “Epiphany” screenplay shortly, I wanted to do a little pretend-trip, this time to an O’Neill Cylinder or its relative Stanford Torus. He and other participants presumed that once such manufacturing facilities had started production, many profitable uses for them would be found, and the colony would become self-supporting and begin to build other colonies as well. An O'Neill Cylinder is roughly 5 times wider than a Stanford Torus, vastly longer, and thus so much larger than the Stanford Torus that the math ceases to be meaningful. A very simple form of continuous ring-shaped habitat is the torus; the classic design shown is the so-called Stanford Torus, which uses mirrors to illuminate the internal surface through a transparent roof. This is the principle design considered by NASA during a 10 week study of space colonization. I think it would take longer than a century if we built it at the same pace as the ISS. A space habitat (also called a space colony, space settlement, orbital habitat, orbital settlement or orbital colony) is more than a bare-bones space station, in that it is intended as a permanent settlement or green habitat rather than as a simple way-station or other specialized facility. [1][2] In the 1920s John Desmond Bernal and others speculated about giant space habitats. It can also function as one for a generation ship for travel to other planets or distant stars (L. R. Shepherd described a generation starship in 1952 comparing it to a small planet with many people living in it.)[12][13]. The structure would have an outside diameter of 30 feet (9.1 m) with a 30 inches (760 mm) ring interior cross-section diameter and would provide 0.08 to 0.51g partial gravity. [citation needed] This provides quick, inexpensive access to both raw materials and the major market. The requirements for a space habitat are many. O'Neill's concepts had an example of a payback scheme: construction of solar power satellites from lunar materials. Most of the nitrates, potassium and sodium salts would recycle as fertilizers. The air of a habitat could be recycled in a number of ways. An O'Neill cylinder is an orbiting space colony composed of two large cylinders which rotate in opposite directions to replicate the effects of Earth's gravity. O'Neill published an article about these colony concepts in Physics Today in 1974. Press J to jump to the feed. If a large area at the rotation axis is enclosed, various zero-g sports are possible, including swimming,[9][10] hang gliding[11] and the use of human-powered aircraft. The space habitats have inspired a large number of fictional societies in science fiction.

Some of the most popular and recognizable are in the Japanese Gundam and Macross universe, the space station Deep Space Nine and the space station Babylon 5. The franchise helped popularize the O'Neill Cylinder space colony (see below in "Literature"), as well as other designs.
