Reply to comment by mrod9191 in Israeli pens plan for belt of solar panels on moon to power oxygen production. With NASA mulling nuclear reactor to generate energy, Ben Gurion University expert says his idea would produce same amount of power with six times less mass. by Zee2A
The article says they propose building a large ring of solar panels above the 88th parallel, so enough solar panels to always have half in sunlight and half in darkness.
I think fission is much more sensible.

I'm wondering how THAT would possibly use less mass

I'm guessing over-estimates on the lunar nuclear solution, best case estimates for solar panel mass, and sidestepping the problem of volume for that many solar panels. Oh and don't forget to pack 10km (!) of transmission line.

My napkin says it's probably more like 400 km of transmission line.

Reasonable idea once the moon is saturated with enough humans though.

I mean, if you're running out of nuclear fuel, sure

At that point Solar thermal might be even cheaper. No pesky atmosphere to get in the way

I wonder if the assumption is a lot of the materials for solar panels could be harvested from the moon fairly easily?

You would not get anything from the moon material wise easily. Without having infrastructure in place to do it. So no.

They would need a lot of cable to make that work.
