Put simple thin reflectors in orbit, I'm fairly certain you can get some kind of polished metal foil or thin panes to give you 90%+ of what's hitting them and beam it down onto receivers.

I'm not anti-nuclear but nukefags are so fucking tiring when they act like they're too based and redpilled to live on solar power. The solar panels, batteries, fuel cells, etc. exist.

Solar accounts for less than 1.7% of the US power grid right now, Nuke accounts for nearly 20%. If we're talking about lack of power infrastructure, solar is nearly fucking nonexistent as a grid supplier. No, I don't fucking care that pretentious upper middleclassers use them to power their shitty houses, if we're talking about managing industrial size HVAC units and chemical air scrubbers, constant power management, and the charging of electrically powered vehicles like you're going to need for any colony in space, and you want to move a lot of power around a grid, Solar ain't exactly accounting very well for itself right now.
Now those problems can be solved, but lets not pretend for even a second that there's even a comparison between atomic and solar power for grid applications, there isn't, solar barely contributes enough to even be talked about in the large scale grid application argument at all.

>> No.12804877

pretty sure he deletes comments that point out the flaws, thus leaving only room temp IQ drones.

>> No.12804893

When did I say anything even remotely political? You said you're talking infrastructure, guess what, solar isn't even two percent of the infrastructure, if it were any less relevant to large scale power generation I wouldn't have even bothered to make a reply, and the further from the sun it gets the less relevant it will be as a power supplier.
Now if we're talking about a Mercury colony or an orbital around Venus, hell yeah solar is your power source, if we're talking about Mars and beyond, solar shouldn't be anything more than a supplementary power source at most, so far as it's proven itself here on Earth, .4 AU *closer* to the sun than Mars, it's OK at the small scale and pretty much irrelevant at the large scale.
How favorably do you think it's going to pan out from solar with 40% less sunlight, especially now that it's known that Mars' barely existent atmosphere is still doing a good bit of work to reduce that incoming radiation even more?

What's your plan for transporting a traditional nuclear installation to Mars, fucktard? US infrastructure does not have anything to do with space because it doesn't have nearly the same kind of mass restrictions. Even Starship isn't going to change that, it will change the magnitude of the problem but it won't make it make sense to use traditional nuclear infrastructure on other planets. It's barely worth it here because we're stuck on the uranium meme.
>How favorably do you think it's going to pan out from solar with 40% less sunlight, especially now that it's known that Mars' barely existent atmosphere is still doing a good bit of work to reduce that incoming radiation even more?
Considering that our starting point is Earth's atmosphere it's definitely doing that job less than Earth, as long as Miguel is doing his job and sweeping the panels. Second, with the volume and mass constraints, Starship can easily pack in >10MW of solar panels in one go even with the efficiency hit, they have low volume and high specific power. There isn't a nuclear system we can say the same about right now.
