Another cloud free day in Scotland let me catch almost 9 hours of this huge and lively prom. Taken with my home made 90mm modded Coronado PST and DMK21 camera. Software: CdC, Eqmod, DSSR, AutoStakkert!, Wavesharp, DVS, Shotcut and Gimp.

Doesn’t take a genius

I assume that's sarcasm 😂

Roughly you need at least 906.000 km² of 1x1m solar panelling.

That's actually not the worst. It seems doable to produce that much square area of solar panels, even for a civilization like us. We need about 500 000 square kilometers of solar panels on the Earth's surface to power our global electrical needs. This is within the realm of possibility

The more tricky part is to actually position it around the sun, that part is what makes it impossible for our current tech level and space infrastructure

Yeah the possibilities of a solar field on the moon is much more sensible.
