  • 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?
