The Kardashev Scale: the Case of "KIC 8462852" (1)

So far, there is no valid scientific explanation for the dimming of a star 1,480 light-years away. Some have advanced the hypothesis of an extraterrestrial system capturing energy. Have you ever heard of a Type II Kardashev civilization? Human civilization has not yet reached Type I (0.73) and will (perhaps) get there in 200-300 years.
A Type II Kardashev civilization is a technologically advanced society capable of harnessing all the energy emitted by its star through enormous orbiting systems. Science fiction?
Great authors such as Isaac Asimov, Carl Sagan, and Arthur C. Clarke have discussed it, among others.
In 1964, Soviet scientist Nikolai Kardashev devised a scale that linked the level of development of potential extraterrestrial civilizations with their ability to harness the entire energy of a planet (type I), a solar system (type II), or an entire galaxy (type III).
An important corollary of his studies is that to find a highly advanced alien civilization, you don't need to try to pick up a radio signal (as the Arecibo radio telescope has been doing for 45 years without—yet—finding anything), but rather observe whether a star's light appears much dimmer than it should be, whether it experiences sudden and inexplicable drops in light energy, or—in extreme cases—whether its light is completely absent. This would mean that "someone" or "something" is "harvesting" the star's energy.
