Reflect Orbital Offers 'Sunlight on Demand' And Light Pollution
A startup based in the USA wants to offer "Sunlight on Demand" even when it is dark by creating a network of orbital mirrors angled to beam sunlight back to surface-based solar farms.
Theodore Sturgeon described orbital mirrors in his 1941 story Completely Automatic:
That ship was quite something. There may be a few of them left - bulky old KH-type ore carriers. The series has been discontinued now, but it seems to me I saw one or two of them on the inter-asteroid runs a few years ago. Her capacity was something like two hundred thousand tons net and she was loaded to the ceil-plates with granular magnesium and sodium for the Sun mirrors of Titan. I don't have to tell you about the seven two-mile-diameter orbital mirrors that circulate around the satellite, making it habitable. You may not know, though, that the girders are all solid mag, because great rigidity isn't needed out there, and mag is cheap. The mirrors are silvered with sodium, which is bright and easy to handle. They have a patrol for each of the mirrors, which patches up meteorite punctures when they occur, squirting liquid sodium around the holes until they fill, then shaving them down with N rays. Well, we were bringing them their stock in trade, and it was interesting cargo to handle.
