Dyson sphere

A Dyson ring — the simplest form of the Dyson swarm — to scale. Orbit is 1 AU in radius, collectors are 1.0×107 km in diameter (10 Gm or ~25 times the Earth–Moon distance), spaced 3 degrees from center to center around the orbital circle.

A relatively simple arrangement of multiple Dyson rings of the type pictured above, to form a more complex Dyson swarm. Rings' orbital radii are spaced 1.5×107 km with regard to one another, but average orbital radius is still 1 AU. Rings are rotated 15 degrees relative to one another, around a common axis of rotation.

A Dyson bubble: an arrangement of statites around a star, in a non-orbital pattern. As long as a statite has an unobstructed line-of-sight to its star, it can hover at any point in space near its star. This relatively simple arrangement is only one of an infinite number of possible statite configurations, and is meant as a contrast for a Dyson swarm only. Statites are pictured as the same size as the collectors pictured above, and arranged at a uniform 1 AU distance from the star.

A cut-away diagram of an idealized Dyson shell, a variant on Dyson's original concept, with a radius of 1 AU.

A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures most or all of its power output. The concept was first described by Olaf Stapledon in his science fiction novel, Star Maker (1937), and later popularized by Freeman Dyson in his 1960 paper, "Search for Artificial Stellar Sources of Infrared Radiation". Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival. He proposed that searching for such structures could lead to the detection of advanced, intelligent extraterrestrial life. Different types of Dyson spheres and their energy-harvesting ability would correspond to levels of technological advancement on the Kardashev scale.
