> it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power

We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon.

edit: Also, this would capture a very trivial percentage of the Sun's power. A few trillionths per year.

In fairness, solar cells can be about 5x more efficient in space (irradiance, uptime).

>>moeadh+Lf
Solar cells have exactly the same power rating on earth as in space surely? What would change is their capacity factor and so energy generation.

The atmosphere is in the way, and they get pretty dirty on earth. Also it doesn't rain or get cloudy in space

I'm all for efficiency, but I would think a hailstorm of space junk hits a lot harder than one of ice out on the farm.

Except it doesn't melt like regular hail so when further storms come up you could end being hit by the same hail more than once :\
