Heat pumps and radiators. Pumping heat to 2x the absolute temperature reduces the size of the radiator by ideally up to a factor of 8.

No, even if you include that. Remember to not commit the mistake of thinking current launch costs are written in stone for all time to come.

What part of "potentially" didn't you understand? The critics of space data centers seem to be focused on the immediate instant and downplaying any potential tech improvements.

Heat pump and a radiator, I believe. Very low mass PV would help a lot; PV can in principle be much less massive than a radiator of similar area.

Medical insurance companies in the US are the agents by which health costs are kept down. In centralized government health systems the government itself does this; in our system the insurance companies do it. They have the negotiating pow

Sorry, when you make an assertion, you don't get to demand I justify questioning it. You need to explain why I should believe you. Your reversal of burden of proof is a red flag that you don't have a good argument. IMO, it is qui

"SpudCell" already has 36 genes; the information encoded there basically cannot occur by random processes. There is still an enormous complexity gap between it and abiotic systems. > somewhere among 2 TRILLION planets in our g

And also when doctors are expected to provide the best treatments or else they can be sued for malpractice.

Health outcomes in the US are affected by higher levels of obesity. If anything, the higher health spending keeps that from being worse. I expect Ozempic and the like to have a significant impact on this.

I could be sad this was gone if I had any idea what it was.

I agree. The Fermi Argument, and the apparent rarity of K3 civilizations in other galaxies, is to me powerful evidence of the scarcity of life. At the least, this suggests SETI should focus on distant galaxies where the Fermi argument doe

The Youtube channel Kyplanet recently had an episode on recent arguments that the Earth/Moon system was formed from at least three giant impact events, not just a single one between proto-Earth and Thea that formed the current Earth an

Were that to happen it could be the worst news humanity ever receives, since it would greatly increase the chance the "Great Filter" is in front of us, not behind us.

That whole effort was predicated on success of efforts to develop fission-free bombs. That never worked out, although the inertial confinement fusion program is in a way its descendant. The scale of ICF reactors shows why it didn't w

The "AlAu4" structure comment got me reading about the aluminum-gold phase diagram. One component there, AlAu2, was infamous in the early IC industry for causing chip failures ("purple plague"). https://en.w

On the other hand, quantity has a quality all its own. Conjectures that survive the gauntlet of immediate proof/disproof could also be interesting.

Non-Erdős problems are also falling. The AIs seem to have some combination of very broad familiarity with math (enabling relevant things from other subfields to be brought in to the proof) as well as patience and "sitzfleisch" (st

Solar power in space is potentially very cheap; solar on a ship is not. The heat problem has demonstrable solutions that people who are physics challenged can't seem to get themselves to accept.

Are folks still thinking orbital data centers are an impossibility? Because this is a strong part of the motivation for those.

I see Cornell was mentioned. If you're ever in Ithaca, NY, visit Cornell's Lab of Ornithology at Sapsucker Woods. The people at the lab are also responsible for the Merlin app that lets your phone identify birds from their voca

Or perhaps the comment you were responding to was asserting "knowing" or "caring" is not something Nature can do.

While you may want AI results to somehow "not count" if the methods weren't disclosed, that doesn't present these results from poisoning the well for others. Once a result (with verifiable proof object) is delivered, th

The sociopathy here is describing a perfectly acceptable activity as somehow evil. You should be ashamed of yourself.

Yes, without any justification let's assume the worst. This is true good faith arguing.

Can cause hyponatremia. Which is where your blood sodium is too low and your brain can swell due to osmosis, destroying it.
