bindeez 2007 recall would be close. tldr childrens toy contained plastifier that turned out to metabolize to ghb, this in turn was put in there as an unauthorized cost cutting measure by manufacturing subcontractor. within 2 weeks of the first incident there was a global recall. note that nobody died and there are no expected long term medical consequences. new batches had added bitrex and undergo qc for this specific contaminant, and brand name was changed
No not really. APKWS or JDAM are retrofits of old weapons with new guidance package. Belgium has no large stockpile of old unguided weapons so they get to design the entire thing from ground up. The principle is similar, its a laser guided beam riding missile shot from a heli or a jet, but APKWS sensors are on leading edge of winglets and this new thing has sensor in nose like a tiny Stugna. overall drop-in APKWS replacement with 10k manufactured per month target
you can distill it before use if you are so inclined, but it would take dry ice and somewhat specialized glassware (distillation of ammonia is more common and it would work just about the same way). there is food grade/cosmetics grade (99.99%) dme available. just in order to not deal with it i would use diethyl ether instead, which can be distilled with normal equipment
man if there was a common household chemical, like plastifier, that causes psychosis after couple months of use in small segment of population, you would absolutely hear no end of this [1]. but you see, now it's an app, oh we're just throwing up hands, can't do anything about it and it's but one of inconveniences that we all have to pay for Progress and Glorious Technocratic Future
[1] i'm thinking here of things like phthalates, bisphenol A, PFOA or paraquat, herbicide linked to increased risk of parkinsons and banned in some countries. their harmful effects need a lot of time to show up and are nowhere as dramatic
that mmwave radar would have to be attached to a drone, because their manned aircraft are unbelievably obsolete. it means smaller size meaning low resolution, and as starlink emits pinpointing them would be very easy when active, much easier than any passive sat dish, and starlink is still in use. i've seen some advice on hiding starlink that includes turning off starlink wifi and using wired connection, because irgc is looking for 2.4 ghz signal (from ground?) and not for 14-ish ghz uplink, so they probably dont have a lot of flying ew/radars
i'm not saying that iranian air force has definitely none of that, but i would be decently surprised if they do have more than 2
there are ways. for example, put a fake hot water barrel on the roof, made from fiberglass or polypropylene or what have you, but not metal, and put dish inside, or in any variety of inconspicuous containers or boxes made from plastic or wood or fabric. some other antennas can be camouflaged as fake chimneys or gutters or water piping or many other things
If one were to make hydrogen producing solar farm specifically, this could have made sense if there were efficiency gains compared to pv + electrolyser. But there ain't, and from what i understand won't be
Ye i've seen that before. Perennial problem with this aporoach is that efficiency is capped below what pv panel can get and also now instead of wiring you need to install purified water + hydrogen plumbing. Also while you just can use only excess of generation for electrolysis, this is always on
technically pv panels are also heat engines. this is why they need cooling
