Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.

    Considering the cost per kg to put something in geostationary orbit, seems less expensive to do GWs of land-based solar, and eventual interconnections, for the same price.

    Wouldn’t capturing sunlight in outer space that was not directed at the earth and beaming it down result in global warming. Effectively, we will have increased the amount of sunlight reaching the earth. That additional energy once used would I think result in additional heating.
