DYSON SPHERE
A Dyson Sphere is an enormous, theoretical structure proposed in 1959 by physicist Freeman Dyson (1925- ). This hollow sphere would be built surrounding a planet and its sun in order to collect all of the sun's emitted energy.

In 1960 Dyson wrote a short paper for the journal Science (vol. 131 p. 1667), entitled "Search for Artificial Stellar Sources of Infrared Radiation".
A Dyson sphere or Dyson ring is the extreme of solar energy. An entire star would be surrounded by solar cells to capture its energy for a civilization's use.
At this time, the biggest obstacle to wind and solar energy is the battery technology.
Dyson spheres might have different emission spectra depending on the desired internal environment; life based on high-temperature reactions may require a high temperature environment, with resulting "waste radiation" in the visible spectrum, ...
A type I civilisation would have the entire resources of a single planet at hand; type II civilisations would be able to utilise the entire power output of a star (perhaps with an immense engineering project such as a Dyson Sphere) while a type III ...
