The latter has more, like Multiplayer 2.4 Dragoon, and Multiplayer 2.5 Elephant(in development), which weren't available locally when I last looked.
There is also https://github.com/longturn/freeciv21 which has an acceptable local client, and finally does not slow down so much when playing larger maps with many AIs, like both FreeCiv and FreeCivWeb tend to do.
Indeed, that seems unnecessarily complex for what is actually needed. I don't understand why the great grandparent comment seems to suggest it's an "unsolved" problem - as if grid-scale solar buildouts don't already have examples of things like motorized brushes on rails for exactly this already.
And it's always a numbers game - sure they're not /perfect/, but a few % efficiency loss is fine when it's competing against strapping every kilo of weight to tons of liquid hydrogen and oxygen and firing it into space. How much "extra" headroom to buffer those losses would that equivalent cost pay for?
And solar panels in space degrade over time too - between 1-5% per year depending on coatings/protections.
Attach heat-pipes with that stuff to the chips as is common now, or go the direct route via substrate-embedded microfluidics, as is thought of at the moment.
Radiate the shit out of it by spraying it into the vacuum, dispersing into the finest mist with highest possible surface, funnel the frozen mist back in after some distance, by electrostatic and/or electromagnetic means. Repeat. Flow as you go.
This is sort of where I think he is going with it. Run the compute part super cold (-60C) in a dielectric fluid. Maybe even at a low pressure. It boils off, gets collected, and is then condensed into something way hotter. Like boiling water hot. This is sent through a high temperature radiator for heat dispersion (because Stefan-Boltzmann has a damned 4), and then pumped back into the common storage area. Cycle indefinitely. Beyond the simple space whatever non-sense, there is a nugget of a good idea in there. Cold things are going to have less internal resistance - so they will produce less waste heat. If you can keep them at a constant temperature via submerged cooling they are also going to suffer less thermal stress due to heat fluctuations. So the vacuum of space becomes the perfect insulator. You can’t have humans getting into them anyways because then you have to reheat and recool, causing stress on the system. Just have to accept your slow component losses. Microsoft and IBM have been working the same basic concept for a while (decade plus), Elon is just throwing ‘Space!!’ into the equation because of who he is. I think it’s 50% hype and 50% this is where the industry is going regardless. I always assumed they would just find an abandoned mine or something. But the always-cold, thermally-stable, no-humans-allowed data center is coming. We are hitting the point where the upfront cost of doing it is overshadowed by the tail cost savings.

Even if that worked, you don’t gain much. It’s not the local surface area that matters — it’s the global surface. A device confined within a 20m radius sphere can radiate no more heat than a plain black sphere of the same radius.
There are only two ways to cheat this. First, you can run hotter. But a heat pump needs power, and you need to get that power from somewhere, and you need to dissipate that power too. But you can at least run your chips as hot as they will tolerate. Second is things like lasers or radio transmitters, but those are producing non-thermal output, which is actually worse at cooling.
At the end of the day, you have only two variables to play with: the effective radiating surface temperature and the temperature of the blackbody radiation you emit.
hits crack pipe used by elon but only after washing it thoroughly What if we used the waste heat to power a perpetual motion device that generated electricity?
https://news.ycombinator.com/item?id=23533175 <- my complaint, a few years ago. Regarding Lex Fridman episode, featuring him. Wondering what the people like about them both? The interviever doing not much at all, the interviewhee talking shit, most eloquently. Yawn.
I thought the whole point of Lex Fridman was to allow interviewees to eloquently talk shit without challenge? Like, seriously, that seems to be the USP; ultra-softball interviewing of weirdoes.
Your brain doesn't need to indulge in sugar to the point of becoming a poisonous vice. You can get more than a sufficient amount eating readily available whole foods.
It's a bit like suggesting we are all addicted to water. Sure, enough of it will kill you, but that's not exactly helpful pedantry.
That aside, where I live my nearest neighbors are about half a mile away, and behind me is nothing but my forest as far as I can see(which isn't that much, because mountain ridges, but still ;-> ), and behind that national forest. When I descend into more densely populated areas, I'm not trailing clouds of purple haze behind me. Be it for reasons of preferred soberness while doing business, shopping, not driving under the influence, whatever.
At the same time I'm feeling undisturbed by most of the stuff, except sometimes for matters of taste. Thinking something like "Ugh! I'd never smoke that crap."
I'm sure there are places where you'd be less disturbed by stuff like that.

I tried that, recently, and barely espcaped a relapse. (Phew!)
