technically pv panels are also heat engines. this is why they need cooling

the steam part is in the rest of hydrological cycle

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

I suspect that we’ll see these “rockets” (missiles?) used for ground based air defenses before too long.

there’s already a ground based launcher for APKWS and FZ275 is compatible with it too

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

noted, fixed

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

he’s trying to become immortal which makes him alchemist at best

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

EY pinged grok and it responded so at least he pays for twitter

i’m aware, last year i’ve been tasked to use a certain process but refused and instead modified it in such a way as to get rid of mercury salt used; it was dissolved in DMF, so (regular nitrile) gloves won’t even help. worse than that, it took me only 2-3 weeks start to finish to figure it out, meaning that anyone else could do that earlier and handful of people were put at risk for no reason. aggression as a result of lead toxicity is probably a bit more complex story and looks like it might have a developmental part, judging by delay and how kids are more susceptible to lead toxicity in general; meaning that presumably mostly adults won’t be affected to the same degree. another big nope on my list would be thallium and cadmium compounds, and while i’d only use sub-g amount at most, there are places where all of these metals are mined, and at one point are in form of fine dust fortunately these are so obscure that i’ve never came across these

long term lead exposure will also do that, and neurotoxic part at least appears to be irreversible. can’t remember how much of it is more of neurodevelopmental thing tho

wasn’t there a case of some supplements that were contaminated with lead? you know, a sneaky neurotoxin with no antidote whose results only show up months later

but then you’re living with red-button-pushers only

i heard a story about varnish factory that failed quality checks after one old guy got fired, he was a smoker and used to spit in the main reactor. some enzyme from saliva made it shinier

it will vary, just after distillation (or RO/ion exchange) it should be closer to 7 then it goes down as carbon dioxide gets absorbed. that’s why it’s buffered everywhere where it matters

in my case the size of the system was so small they didn’t have that excuse, yet they were only ever able to get correct results after experimental data was handed over to them, zero predictive power, useless

seeing that jargon file has an extensive page on retrocomputing feels like figuring out that there were archeologists in ancient egypt

some people would tell you that we can simulate small bits of chemistry but it’s flat out wrong (i might be biased as i’ve wrangled for a year with computational chemists about results that don’t conform to reality) and even then errors are so large that’s it’s useless
