    Space based mirrors for asteroid mining. Bounce a sh*tton of light from the sun around and just melt asteroids. Love that in the Troy Rising series.

    Lots of problems getting there irl (need a better way to get out of the gravity well, and light speed lag for command and control would be a real issue) but the idea is just too fun.

      That sounds like a great way to accidentally muzzle sweep a thousand international satellites with a billion-kWh laser beam. Not saying it’s entirely a bad idea, but having invisible unshielded beams of stupendous energy bouncing all over the solar system sounds like a recipe for a couple accidental meltings. I could just see someone making an adjustment to the next mining target without informing China and whoops, that secret manned satellite you sent up a couple months ago is now slag.

        Depends how it’s focused. It wouldn’t be a straight coherent beam, because that would actually break thermodynamics if you could produce it from sunlight.

        Yeah they deal with that in the book series. Lots of AI who do space traffic routing space ships around the beams so as not to get fried.

        It’s also used as a weapon in the books to defend the solar system. Fune books. I read em once a year or so.
