The Russian Plan To Use Space Mirrors To Turn Night Into Day (vice.com) 126
merbs writes: Throughout the early 90s, a team of Russian astronomers and engineers were hellbent on literally turning night into day. By shining a giant mirror onto the earth from space, they figured they could bring sunlight to the depths of night, extending the workday, cutting back on lighting costs and allowing laborers to toil longer. If this sounds a bit like the plot of a Bond film, well, it's that too. The difference is that for a second there, the scientists, led by Vladimir Sergeevich Syromyatnikov, one of the most important astronautical engineers in history, actually pulled it off.

The move won't happen anymore, because it happened already.

These methods were just bad, the versailles hall of mirrors room needed tons of candles in order to be properly lit.

From the article, they were planning on lighting up urban areas only. The mirrors wouldn't be large enough to light up more than a city, and the light would only have been the equivalent of a bright moonlight. And cities already have electric illumination at night. So this would only be substituting current electric night time lighting in city centers with the reflected light, which would have the advantage of cutting energy costs. The idea was being pitched as an energy saving measure for city centers. It's not so terrible if limited to urban centers.
Sure it's not such a terrible energy saving measure...unless the cost to build the damn thing was eleventy bazillion dollars, sending your ROI into fucking orbit.

Some quick Googleing and I see that Boston, as an example, spends 8 million annually just on street lights and space X costs $100 to 260 million for a launch. Assuming a 20 year lifespan of the satellite, you end up with $160 million to mess around with. So it's not completely absurd that such a plan might pay for itself if it can be done with a single satellite that is cheap enough and lasts long enough. If doing multiple cities, there might be some savings in manufacture of satellites as they aren't all o

Most urban areas get significantly brighter during the night when it's cloudy out because all the light pollution reflects off the clouds (even more so in northern climates when there's also snow on the ground). Obviously, without the streetlights you're going to have a lot less light to reflect, but you could probably get away with a lot less of them.

If I recall correctly burning enough fossil fuels to produce 1 watt-hour of thermal energy produces CO2 which, over the course of it's average lifetime in the atmosphere, will retain a million watt-hours of solar thermal energy.

It may block the same amount of sunlight as it passes over the day side of the earth (unless it is in a polar orbit that is synchronized with the earth's revolution around the sun).
Perhaps even more, since its reflective timeframe would be limited as it would pass into the earth's shadow. Also I assume the material's opacity is greater than its reflectivity.

Like so many other discussions about stuff in space or terraforming, this was discussed in KSR's Mars trilogy. They used an orbiting "soletta", a flexible mirror that would reflect onto itself. It was capable, when tuned, of either acting as a lens or as a prism, either focusing or scattering sunlight. You do that by making it out of conical strips which can alter their angle. If the angle of each cone is made more acute as you proceed towards the outer ring, then you get a focusing lens. But if you make ea
