No Stupid Questions@lemmy.world•Realistically, what do people plan to do on the Moon and Mars that requires a permanent, or long term human presence there?
0·20 hours agoMusk believes in a sort of secular mormonism except instead of magic he has money so he tries to eventually, after millenia to spread his progeny over the entire known universe

No Stupid Questions@lemmy.world•Is there something like join-lemmy.org that doesn't list tankie instances?
0·2 days agoYou can join from voyager app, and the three instances aren’t listed by default, or so it seems at least
no no, it makes sense. alpha male, so not ready for release and bugs are to be expected

LG would be South Korea. Maybe it contacts tracks on PCB below and it’s some kind of semi-conductive rubber

No Stupid Questions@lemmy.world•If someone's injected with cancer cells, they develop cancer. Could at least part of the increase in cancer be to do with people getting other people's cancer cells inside their bodies?
0·1 month agocancer is in large part an old people disease, if you avoided dying of cholera you’re more likely to die of something else. also now there’s a lot of people who were exposed to carcinogens decades back, and we got better at treating pr preventing some other common causes of death like stroke or heart disease

Technology@beehaw.org•A Finnish town is heating itself with 2,000 tonnes of crushed rock: its giant “sand battery” can cover almost a month of heating demand and has cut district heating emissions by 70%

1·1 month agoThis will continue as long as there are CCGTs used as baseload, then it will drop as CCGTs (and biomass + waste burners) will cover the gaps

4·1 month agomethane cracker? that’s a very unusual unit that outputs hydrogen and carbon. i could find info about opening of ethane cracker in 2025, but that’s for plastics, next to shutdown of another similar unit

Ask Lemmy@lemmy.world•How can you detect cancer spreading Nitrates in the water supply?
0·1 month agoyeah this is only practical option, the analysis isn’t that expensive, but equipment to run it is. but also people who have their own water wells have to submit their own samples

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
1·1 month agoNo they don’t, there’s still 4 units one per launcher. Most of problems you mention seems to come from energy storage system. Energy is stored in the flywheels, which requires annoying converter, so chinese variant uses giant set of supercapacitors instead which is just a bit heavier and has less problems with communications interference. Also can be split in many parts and fit in any space you have. Mostly benefit of being designed later. Zero surprises if americans figure it’s better but institutional inertia keeps them using the old one

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
2·1 month agoThey don’t actually. Steam catapult is operated with completely separate steam supply, and major design goal of ford class was to remove it so even if pedo in chief wanted, retrofit is physically impossible. That separate steam supply needs extra freshwater because it’s not condensed and recovered. EMALS is much milder on plane and pilot because it’s a big linear motor that gives constant acceleration instead of spike then decreasing like with steam. Efficiency of steam catapult is also dogshit compared to turbine + energy storage system

DCM is also about the only good solvent left that is also resistant to lewis acids. I think that some people were pushing for benzotrifluoride as a replacement, but it just straight up doesn’t work as well where i tried it
Tbf before “do it in DCM” was “do it in CCL4” or “do it in benzene”, DCM just works without nuking operator’s liver
Lots of these new green solvents are also annoyingly polar so perhaps they can be used as replacements of other polar solvents but not anything else. I’m not using cyrene, fuck that
TFA is used because it works and is shelf-stable. Replacements like HCl in ether or ethyl acetate are bitch to make and when these can be bought, they have to be refrigerated all the way. Straight up not worth the effort on small scale
