<p>a party balloon - say a cubic foot - is about 2g of hydrogen. Involves 16g of oxygen. So we're talking 18g of very fast burning, borderline detonating mass. Releases 240 KJ of energy.
To compare the hand grenade - 60g TNT <a href="https://en.wikipedia.org/wiki/F-1_grenade_(Russia)" rel="nofollow">https://en.wikipedia.org/wiki/F-1_grenade_(Russia)</a> - releases the same 240 KJ of energy.</p>

<p>i already wrote that drones (or more precisely - cheap semi- and fully autonomous high-precision weapons) are a new strategic parity weapon <a href="https://news.ycombinator.com/item?id=44203848">https://news.ycombinator.com/item?id=44203848</a> - it has been playing that role in Ukraine vs. Russia, and now in Iran vs. USA.<p>Interesting that the original post demonstrates the same reaction to that new strategic parity weapon as the one caused back then by the original strategic parity weapon - the nuclear - to dig into the ground on the basis of the same key principle of "nowhere is safe"<p>I'm sure that even in the future when another strategic parity weapon emerges - say it would be a throwing rocks from space or a cheap mass production of autonomous nanobots precisely delivering some strong poison/pathogen - our first reaction would be the same urge to dig into the ground.</p>

<p>look at the history of technology, and before that to the biological history - how long it took from single cells to multi-cells vs. for example how long it took from lizard brain to human brain - the things are naturally going exponential (my thinking why - <a href="https://news.ycombinator.com/item?id=9418811">https://news.ycombinator.com/item?id=9418811</a>) at least until they hit some wall, yet so far hitting walls mostly  only stimulated even more advanced development.<p>There is an issue of the "non-uniformity of the spread of the future" though with fast development, and the faster the development the stronger the non-uniformity and the tensions it creates. Strong non-uniformity and resulting tensions have tendency to resolve catastrophically on their own at some point if not solved/smoothed by the other ways before.</p>

<p>>you're opening incentives for people to do so<p>how about short-selling of stocks, isn't it the same thing? I'd even argue that sinking one ship affects say 10 people of the crew who most probable will survive in the warm Gulf waters whereis sinking a company may affect many people life outcomes probably causing a number of indirect deaths. CDS of 2008 would be similar example.<p>>buying OIL or Palantir is morally questionable, it does not create such direct incentives<p>it creates direct incentives to suppress competitors - wind and solar energy for OIL, and whoever Palantir competitors are.<p>Wrt. "Hormuz open" - does the "open" definition includes the new fee Iran would be taking for the strait traverse (something like $1/barrel, nice for Iran, how come that they had't implemented such an idea before? one can only wonder)</p>

<p>It was a government call. I grew up in USSR and know very well how those government "calls to volunteer" work in totalitarian regimes. Especially in a wartime country where even in peacetime they would kill people even just for being incorrectly dressed.<p>Anyway, as i said in the other comment, it is actually not that important how all those people got there. The key thing here is that it was a deliberate government act of human shield creation.</p>

<p>Whether sauna is hot or not depends on whether you enjoy the cold water plunge afterwards :)<p>The typical preset on dry saunas in Bay Area is ~165 F (73 C). Which is cold. Waste of time and money :). Usually, by closing or pouring cold water on sensor, one can make it to 180-190 F (82-87 C) - this is where you start to feel like you are in sauna, though it takes prolong time to heat you up enough to enjoy the cold plunge. If you're lucky enough, you can get to 200, 210, 220 F (104 C) - this is where you start to feel relaxed like as if the heat is working inside you.<p>>Are you actually throwing water? Because even with 80 the steam is pretty hot<p>Of course those numbers would be impossible to enjoy in steam sauna. The only steam sauna that had a wall thermometer that i've visited in recent years was showing 55 C when it already felt pretty well and hot.<p>Note - steam sauna and "throwing water" are 2 different things. The steam sauna is a machine generating a lot of steam, so the room is close to 100% humidity.<p>The "throwing water" is like Russian "banya" - it is in-between of dry and steam, though frequently is more close to dry Finnish sauna - wooden walls, stove, etc.  where in addition to the heated air, you'd throw a water on the heater/stones thus adding a hit of hot steam to that air (in some "banya" configurations if you happen to be close to and in the immediate  path of that steam you can sometimes get light burns).</p>

<p>no, the million or two is small battlefield drones, mostly quadcopters carrying an RPG warhead or similarly sized payload. The long range drones - and they carry only relatively small, like 20-50kg payloads  - are well under 100 thousands. FP-5 was declared 1 per day half a year ago. By now i think we've seen may be 10-20 such missiles used - they use real turbo jet engine, there isn't much of them available, and they are expensive.<p>>They just took out 40% of Russian oil export capacity.<p>Yes, Ust-Luga and Primorsk. Very successful hits. Painful for Putin. Yet it isn't a knock-down. Russia is like a big drunk guy in a street fight - just delivering painful blows to him doesn't help, you have to deliver a knock-out blow, and unfortunately Ukraine still seems far from it.</p>

<p>you miss that i was talking about 650km/h "drones" (because, yes, it was already 3rd year of war, and 200km/h drone like Shahed became much easier target - this is why Russia has started to also use the 600km/h modification of Shahed with RC jet engine). There is related discussion under that comment addressing your point about interception.<p>>Both countries do the type of attack drone clustering you suggest<p>Ukraine still isn't completely there. They do attack Russia with up to 200 drones/day. They seem to never cluster more than a few, and the drones they are using are comparably small - 50kg warhead - and slow, 100+ km/h, almost always less than 200km/h.  So they are easy to intercept/shoot down, almost never penetrate Moscow air defense, and do noticeable damage only when hitting flammable targets like oil/gas industry related.</p>

<p>that is the point  - to make you scared to fly your drone, anywhere, anytime. That is among the main differences between democratic society and the rest - a citizen of democratic society knows the extent of his rights, and where he would be crossing the line into violation of law, and that makes the citizen pretty assertive in his rights. That assertiveness isn't compatible with the non-democratic societies (or with authoritarian abuses of power in a [still overall] democratic society).</p>

<p>How they were hit? Multiple drones overwhelming relatively small number of air defense systems. Systems like Patriot are great against several very capable targets like ballistic missiles. Such (expensive centralized) systems do much worse against multiple widespread targets like an armada of low flying low speed drones (add to that low speed cut-off filter to avoid hitting general aviation and the likes).<p>Point defense systems like Skyshield (or even that very old and cheap - $2M - Gepard <a href="https://en.wikipedia.org/wiki/Flakpanzer_Gepard" rel="nofollow">https://en.wikipedia.org/wiki/Flakpanzer_Gepard</a> ) work wonderfully against all those drones coming in.<p>Heck, even just soldiers with MANPADs would have easily shot down those drones (you just have to distribute those soldiers to all those strategic objects which hasn't been done)<p>We have classic situation here - everybody have been watching Ukraine war for 4 years, yet nobody has prepared for such style of war.<p>>I am unconvinced that even AMZN's pocket change could realiably protect against the kind of attacks we see in this war<p>No even low flying slow drone - pretty typical situation of top Russian cruise missile shot down by Gepard<p><a href="https://www.reddit.com/r/CombatFootage/comments/zdbvim/a_ukrainian_gepard_shooting_down_a_russian_cruise/" rel="nofollow">https://www.reddit.com/r/CombatFootage/comments/zdbvim/a_ukr...</a><p>Also AMZN has its own drones dept - in "hot" zones in "hot" times they can put several people with drones (in the high speed configuration) to be used for interception.
