They intend to beam the energy to earth through a laser. I wonder if building a space-mirror and focussing a beam of sunlight would be a much easier and scalable solution.
Though I guess you would need multiple base stations to beam it somewhere where there's no clouds?
- En_gr_Student 8y agoUsing a wavelength transformation to send this through the non-absorption windows means more energy hits the ground and you aren't hacking terrestrial albedo in a bad way. That global warming is about absorption of sunlight, so putting a lot more sunlight on the same absorption percent means more heat retained. It doesn't do any good to cut gwp materials in the air, then increase sunlight hitting the atmosphere in a way that makes heat retention higher.
