This Startup Wants to Use Space Mirrors to Light Up Earth at Night. Feds Just Said Go Ahead

2. This has been proposed for many many years (maybe not proposed but speculated to in many Sci-Fi books.

Of course, seems rather difficult to do, in real life, to (1) get the thousands of pieces of mirrors up there (or similar objects), get arranged precisely, gather the collected energies, ship it to Earth somehow for use, etc. Sounds like a lot of complicated tasks. They've done this on a far smaller scale, e.g., solar on satellites, but not on the scale like this.

Worth trying but make it scalable, so if successful, can easily add to, e.g., attach it to the space station/etc., keep adding to it over the years instead of rebuilding the whole damn thing again and again and again.
