      My startup is going to rent sunlight interceptors that block the extra sunlight sattelite beams that your neighbour rented and what is keeping you awake all night.

    This gives me a great idea for a new startup! I’m going to put a giant mirror in space, and you’ll need to pay me to turn OFF the sunlight at night.

      The people behind that startup are in tears strangling each other wishing they thought of this.

    I’d like to have darkness during daytime. I’m not sure I would pay for it, but I’d like it very much.

    It’s so dumb uggh. Getting the same power output as the sun would need a MINIMUM surface area of the size of the area on earth it would illuminate.

    So say the use case is extending daylight time in Anchorage, Alaska during winter. You would need a mirror that has MINIMUM surface area that of Anchorage. Somehow, it would need to be in an orbit that can reliably reflect light to Anchorage at all points.

    Then, it would most likely be in low Earth orbit as putting it higher would require bigger mirrors. However, if u are in LEO, u are also moving incredibly fast. You would thus need an array of these super large mirrors.

    All of this for what? Something that an led can do incredibly easily?

      Would it not be possible to deflect it through a lens? Couldn’t that increase the spread area significantly and because of the contrast at night you would only need a fraction of the light intensity to make an area feel well lit?

        You don’t need a lens, just a differently shaped mirror. Their point is just that the light you capture is based on the mirror’s surface area, so if you are selling sunlight-equivalent amounts of light you would need a mirror of equal area to that you are selling. You would not need such a large mirror to sell an area of dimmer light, and you would not need a lens.

        • A convex mirror could work, sure. A lens would be impossible to construct for the size necessary.
        • I don’t get what u mean by “contrast at night”, but sure - let’s assume that you would need 5% of the power at noon. You would still need a mirror with a surface area of 5% of the area you are illuminating.

      Okay, luddite. All of the studies resoundingly show that pointing a giant space mirror down toward our collective homes is a great idea.

      The space mirror is only going to enhance the night sky by better lighting up everything else. And since it’s a mirror, you get double the star goodness for whatever you want to see!

        You mean zero stars because many nights the moon alone provides enough reflection to blind the sky essentially.

        I was an adult before i learned that in actual darkness we can see the andromeda system and the beautiful colors of our own galaxy at large with our naked eye.

        I used to think pictures like these required super expansive special camaras… and to be fair i was correct in that assessment. But i failed to realize the ultimate light sensor is simply our own eyes.

        The sky is beautiful, its sad how hard it is to catch a real glimpse of it in proper light contrast

          I grew up in an area that was fairly dark. Probably somewhere between Bortle class 3 and 4 when I was young.

          When I went backpacking in the Rockies, it was like nothing I had ever seen before. The night sky is vast and beautiful, and so full of lights and color. Constellations are hard to make out because there are so many dots to look at, rather than the light being too faint to make out.

    Not exactly a new idea. Soviets tried it. Expenses were huge, and something that nobody thought of much back then is that nature would surely found itself hanging upside down…
