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

Showerthoughts@lemmy.world•Do you think politicians purposefully make the world worse so that their lawyer friends have more cases to make money from?
5·7 days agolol as if they could plan this far forward

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?
2·7 days 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
this is how antibodies work
it would be about as reliable either way

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%
4·10 days agothat’s no problem at all, systems like that are in use

Technology@lemmy.world•More Renewables Lead To Lower Demand For Methane In EuropeEnglish
1·11 days 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

4·11 days 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

3·11 days agoLithium-iron is about 2x more expensive, there might be different availability and energy use during manufacture is probably higher

Ask Lemmy@lemmy.world•How can you detect cancer spreading Nitrates in the water supply?
7·13 days 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
1·14 days 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
2·14 days 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

5·14 days agoEMALS has been around for over 15 years so naturally trump lost interest
ah well then yeet that and instead

rtl-sdr uses the same chip as dvb-t tuners, but the everything else part is completely different
