I think a realistic O'Neill cylinder would not have a single fake landscape inside a huge open space, dotted by pastoral farm buildings and quaint towns. The O'Neill Cylinder. Plants tolerate higher radiation levels and don't care about Coriolis forces. Rama Object, inspired by Arthur C. Clarke's story Rendezvous with Rama. In a simple, non-spining station, the mass/inertia of objects is only noticeable if you want to move them relative to the station. The O'Neill cylinder, also called an Island Three habitat, is a space habitat design proposed by physicist Gerard K. O'Neill in his book The High Frontier. If anything it was an O'Neill Cylinder that was tailored to fit the forces that longitudinal space travel would impart upon it, with the high wall on one side of the "ocean". I don't feel that the Halo franchise is a reasonable example of the O'Neill cylinder because the environment of the Halo world is more of a fantasy habitat for Aliens.  O'Neill proposed the colonization of space for the 21st century, using materials extracted from the Moon and later from asteroids. THE O'NEILL CYLINDER ... small isolated cells is desirable since any disease in one unit could be confined and that unit sterilized with solar radiation prior to a new planting. A different but related design, the Kalpana One: The Kalpana One is an interesting design, and quite suitable for the first generation… In the 1970s, Princeton physicist Gerard K. O'Neill, was tasked with designing a free floating space colony with existing technology, materials and construction techniques.  In the book O'Neill proposes the colonization of space for the 21st century, using materials from the Moon. Everything O'Neill Cylinder and rotating habitats. They are used exclusively by the Jovian Republic, where the rocky shell of the hab protects the residents from Jupiter's dangerous radiation. It's a cylinder colony, with its own on-board weather and everything. A Stanford torus needs radiation shielding on all four sides, but the cylindrical section of an O'Neill cylinder is like a stack of Stanford tori which only needs radiation shielding on one side (the bottom). Worldbuilding Discussion: A Medieval Society Inside of an O'Neill Cylinder. The O'Neill cylinder (also called an O'Neill colony) is a space settlement concept proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. O'Neill cylinders can be quite large. oneillcylinders. Lots of water is heavy. The basic principle is fairly simple. In a series of studies held at Stanford University in 1975 and 1976 with the purpose of speculating on designs for future space colonies, Dr. Gerard K. O'Neill proposed Island One, a modified Bernal sphere with a diameter of only 500 m (1,600 ft) rotating at 1.9 RPM to produce a full Earth artificial gravity at the sphere's equator. Each black hole wouldn’t last for very long, owing to their small size and rapid decay, so the ship would come equipped with gamma ray lasers to produce black holes ‘on-demand’. The O'Neill cylinder (also called an O'Neill colony) is a space settlement design proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. Artist's depiction of a pair of O'Neill cylinders. The O'Neill Cylinder is much larger but being cylindrical, the weight is supported by tension in two directions increasing the mass needed. In a spin habitat, centrifugal force pushes objects on the inner surface against the surface. The view point is from up in the "mountains" at the hub farthest from the sun. This is a good diameter for a space habitat: if it is an order of magnitude larger, the structure won't hold together when it spins; an order of magnitude smaller, the Coriolis force is more noticeable. The cylinders would rotate in opposite directions in order to cancel out any gyroscopic effects that would otherwise make it difficult to keep them aimed toward the Sun. The Stanford Torus is the result of a student competition at Stanford and is by far the most likely to be built. The O'Neill cylinder (also called an O'Neill colony) is a space settlement design proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. 54. The farm cylinders need only be suprisingly few and small. Each would be 5 miles (8.0 km) in diameter and 20 miles (32 km) long, connected at each end by a rod via a bearing system. An O'Neill cylinder requires less mass for radiation shielding, because geometry.
