Comment on Controversial startup's plan to 'sell sunlight' using giant mirrors in space would be 'catastrophic' and 'horrifying,' astronomers warn

  Ohh, I know of one sack lying piece of shit orange man with a fake tan who could use some concentrated sun rays. And quite a few of his accomplices.

  This is the same reason that harvesting solar energy in space and beaming it down is also a stupid fucking idea. It’s politically problematic. Nobody wants anybody to have giant death rays in space, so there’s effectively no way to get the energy down to earth. It looks like we’ll all just have to rely on all the green technologies that already work.

    Weaponization or dangerous rays are not among the challenges facing space-based solar.

    Contrary to appearances in fiction, most designs propose beam energy densities that are not harmful if human beings were to be inadvertently exposed, such as if a transmitting satellite’s beam were to wander off-course. But the necessarily vast size of the receiving antennas would still require large blocks of land near the end users. The service life of space-based collectors in the face of long-term exposure to the space environment, including degradation from radiation and micrometeoroid damage, could also become a concern for SBSP.
