Especially the 1 km square receiving grid. They say the energy would be like standing in the sun. I'll bet there is more to it than that, like cancer or radio interference or other unknown nonsense. But... wonder what a solar array 1km square would receive from the sun itself? Honestly, I'm reminded of moving across states. When I went to move, every pound of stuff had a price, like .50/lb. So I could figure out if something was worthwhile to move. If something weighed 200 lbs, it had to be worth $100 just to break even. In the same way, how much energy would we expend to get those solar panels into orbit, and how much would the receiving array cost to build in time + real estate. Would it break even compared to expending the same amount of money on the ground? like if launching an array into orbit + ground station was $10b dollars, how much ground-based solar could you get for $10b dollars. And with batteries? I'll bet the economics of ground-based is pretty good.
