  • The previous 40kW proposal linked in the article mentions it would allow operation where solar panels aren’t feasible, like permanently shadowed areas where water might be. There’s also the dust problem to solve with solar panels, although this would also be a problem for nuclear reactors since their radiators could become less efficient from dust buildup.

    There’s a lot of extra costs associated with making solar panels space worthy. No atmosphere also means no radiation shielding and no cooling. I actually managed to find satellite solar panels for sale: https://www.cubesatshop.com/product/solar-panels/. They have front and back panels but if we assume they didn’t have a back and all panels faced towards the sun it would be ~120W. That gives us $133/W, which means 100kW would be $13.3 million. Unfortunately the mass isn’t listed, so we can’t estimate the launch costs. I don’t have a way to estimate the cost of a fission nuclear reactor on the moon since we don’t know how it would work yet, so this calculation is mostly for fun. That math would change significantly if we are able to manufacture solar cells from lunar regolith.

    In nuclear’s defense, we’ve been sending plutonium-238 into space since 1961. There’s been a few accidents, but the fuel casing has been improved so that the later accidents resulted in no leakage. That was in the early days, so we know a lot more about safety now. Do you think the risks are too high for any nuclear fuels in space, or does uranium pose unique risks?


  • It was a bad demo. I solved every “puzzle” near instantly except the robot, where I didn’t realize the arm had to be on a specific side. The demo was basically the story prologue and intro tutorial, but then it stops without ever giving you a proper puzzle. It didn’t do a good job of showing depth in its mechanics. Each puzzle has a single correct obvious solution. I wanted to optimise, but that single solution doesn’t give anything to work with. Forget single solution though, most levels are a single part. I get that they’re introducing new parts, but you’re allowed to what you’ve already taught even when introducing new mechanics. The lack of interaction between parts is a large part of what makes it seem so shallow. It makes me question if the dev even knows how they interact.

    I didn’t mind the story at first, but it overstayed its welcome. Your “less is more” is an excellent way of putting it.

    Hopefully the full game will be better, but I’m not counting on it.





  • https://xkcd.com/978/ The problem is that a lazy answer builds credibility for a source or fact. You may try to disclaim that it’s unreliable, but the mere act of suggesting an answer implies your own support for it.

    “I’ve heard there’s studies that suggest vaccines cause autism.” is a lazy answer to the question of vaccine safety that ignores the complicated nature of academic research. What it does do is build consensus. Over time, that lazy answer repeated gets you to state where a lot of people doubt the safety of vaccines.

    I realize we all live busy lives and nobody has time to research things in great depth. Some people barely research major purchase decisions. What people are trying to communicate here is that an AI answer has very low credibility along the lines of “my uncle who works at Nintendo”.

    We don’t need you to act as a human interface for ChatGPT. If you want to use ChatGPT, use it as a starting point for your own research. Ask it questions like “Where could I find information on this topic?” and go from there. Of course, that’s a lot of work; but you can always choose not to post.

    If you have life experiences that give you insight into a topic, or you did research and found a good source; please comment and share your insights. They add value to the conversation and it’s why most of us are here.


  • I don’t know how you would go about banning parties. You would have to ban almost all forms of cooperation.

    I agree with Madison that you can’t treat the causes of factionalism, you can only mitigate its effects. Madison argued a large government with many members makes it harder for one faction to seize a majority.

    Unfortunately, the founding fathers fucked up bad when they chose first-past-the-post/plurality as the voting system. Social choice theory shows that plurality voting will naturally gravitate towards a two party system. No third party can get a single toe in the door because of the spoiler effect. Plurality’s only benefit is its simplicity, everything else about it is somewhere between bad and horrifying.
