  • 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




  • yeah that’s because that’s not what happened, there were multiple targets, not just one. that signal chat directly mentions “mutliple targets”, it could be 5 it could be 15. if goldberg stayed in this chat maybe we’d know how many exactly

    weapons mix suggests that at least some of these were chosen to limit collateral damage (two F18 sorties, Tomahawks launched - these could be used against hardened targets, like bunkers or caves, and targeting shifted from weapons to leadership, but probably not completely - but also drones, and drones can’t carry heavy weapons like F18 can)







  • 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)



  • 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
