the point is, as always, to continue doing business as usual (in this case, by inhibiting BEV adoption). that fuel is carbon-neutral but also extraordinarily wasteful. trump's deal is something called "clean coal", which isn't (it suggests carbon capture, but it's not a thing, they marketed normal emissions control like we have in europe as some unusually green innovation). i think he was also captured by gulf monarchies for the one hour when their representative talked to him

e: wait it still makes smog so checks out

recently learned about electrofuels. it's a hypothetical rube goldberg scheme where you put enough energy to propel 5-7 EVs in, and pull out enough gasoline to fuel one car. it's sold as a green technology, because now gasoline is green somehow. this spin ignores that it would require massive buildout of renewables + nuclear, and just by doing this electrification of many energy end uses just makes sense, including transportation. (what the fuck is train??) it's also sold as a long term storage for renewables, but i struggle to see how scheme that has less than 30% roundtrip efficiency can be considered "storage". just build more renewables and don't use them all if needed

i thought they were yet another rationalist offshoot

real. every prediction i got from computational chemists was wrong

like any other, it can be even seen deforming in the last frames

slowmo shot of the last american nuclear test delivered by airdrop, it is spherical, but not because of condensation cloud (that moves away quickly and is transient anyway)

does it mean that libertarians will lose interest in it real soon

there's a couple of amusing hells inside that job, you either have to deal with construction crews and contractors, jump between power poles including in cold and rain, wrangle with paperwork for permits for new lines, or fix horrors left by someone before you, it can be also dirty and people-facing

in this case it's hard to tell one from the other

i still think that lots of people damaged by chatbots will stop in their tracks when this vc money burning charade ends, they won't be able to set up it all locally because chatbots brainrotted them even if it was possible in the first place

If you don't care about precise size, balls can be made cheaply by dropping drops of metal down tower where they are cooled by air as they fall, and then by water after they solidify. Then just sort by size

Ferrite beads allow you to use old calibration. If you make 1:1 balun just by threading coax through toroid, you can use old calibration as well provided it's the same coax. Keep in mind minimum bending radius of coax. There are other designs, like using twisted pair on toroid, then you have to include balun in calibration as well (it adds some electrical lenght). If you noticed changes after making air core, this suggests that you do have some common mode current, this will make your measurements sensitive to random changes as rf current flows on the outside of cable where it shouldn't

I've seen people using PE-Al-PE pipe for variables, this gives you layer of good dielectric (polyethylene) (but not as good as air) in dimensionally stable form. One connection is aluminum layer inside the pipe, and for the other you'll have to figure it out on your own. Retuning might be required anyway within the band (magloops are narrowband) Common way to make variables is to bolt two of them in series, so that no sliding contact is used, moving part is the same for both. This is good for high voltages also but i'm not sure if you'll need it
