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).

And how much of that power would be spent on high speed communications with Earth that aren't, you know, a megabit or two per second

>>bastaw+ri
That's pretty much a solved problem. We've had geostationary constellations for TV broadcast at hundreds of megabytes for decades now, and lasers for sat-to-sat comms seems to be making decent progress as well.

Which satellites are operating from "deep space"?
