yeah, you better do

there's not that many of them and one Trident missile costs only $31M

both 198Au and 199Au have half-life in order of 3d, waiting 1y will decrease radioactivity to nothing (5E40 times for 198Au and 1.3E35 times for 199Au. others are shorter-lived and fission products can be probably separated chemically to an acceptable degree). it's also pretty decent deterrent against stealing it, and decay product mercury is stable and easily separated. i'm not even sure if irradiating gold with neutrons would make it worthless because of that. might even go up in value because there's now a story behind it. bigger problem would be that it's scattered everywhere

i think there was an update or two since

also the minimum deterrence always kept up by brits is that there's at all times enough nukes in submarines to destroy moscow. french have some more fine-grained options

triple the defence budget

okay i see now

but what if you put another split ring inside it, it'll be different

this is just small-ish magloop

i've seen some people make magloops out of bike rims, it's similar sized. the smaller it is the lower radiation resistance, higher currents and voltage on capacitor, narrower bandwidth, and lower efficiency. i don't remember how it scales but efficiency goes up fast with size, 1m dia magloop is already better. downside is that tuning becomes impossible on higher bands (capacitance required for this is below minimum capacitance of capacitor that you have)

also cryonics and "enhanced games" as non-FDA testing ground. i've never seen anyone in more potent denial of their own mortality than Peter Thiel. behind the bastards four-parter on him dissects this

will it antenna? i think it will

split ring resonator has already two different lengths of paths so - even without accounting on how these two interact - you could expect two different frequencies where it's resonant, with peaks perhaps overlapping to a useful degree making a decently wide band possible. it looks a bit like halo antenna with parasitic, downside being that it's probably a bit hard to feed it, circumference has to be halfwave on lowest frequency and if made for HF it'd be gigantic

i think it's more useful to think of magloop as extremely shortened, low impedance, low bandwith halo antenna

 
 
 

(they didn't learn their lesson)

 

don't ask whose plan tho

 

might be too credible

of course he was afraid of russian nuukes. this only prompted Ukrainian engineers to bypass use of starlink entirely and current sea drones, like the one used in second Kerch bridge strike, or these used against SIG tanker and Olenegorsky Gornyak landing ship use domestic technology only
