- Comment on Grid-Scale Bubble Batteries Will Soon Be Everywhere 1 day ago:
There is a thermal energy storage included as s major part. This works because compressing CO2 to 55atm adiabatically heats it up to some 450-ish C, so that heat is pretty high grade, and only the final stage cools it down with heat exchanger open to air. In discharging direction, some heat is taken from outside air to evaporate part of CO2 and heat stored is used up
- Comment on Grid-Scale Bubble Batteries Will Soon Be Everywhere 2 days ago:
compressors, turbines (like steam turbines), piping, container for liquid carbon dioxide, lots of plastic for the bubble, something for thermal storage, dry and clean carbon dioxide, these aren’t unusual or restricted resources, don’t depend on critical raw materials or anything like that
- Comment on Grid-Scale Bubble Batteries Will Soon Be Everywhere 2 days ago:
Compressed air without heat recovery is more like 30%, so this is huge

- Comment on How does the private equity bubble compare to the AI bubble if at all? 1 week ago:
Or you could use different hardware, maybe from competition, because result isn’t worth electricity it used
- Comment on How does the private equity bubble compare to the AI bubble if at all? 1 week ago:
gpus as used for genai aren’t really suitable for normal loads like aerodynamic simulations, genai uses low precision data like fp8, fp4, blackwells and such are optimized for it so hard that you can’t really do anything else on this thing
- Comment on Revealed: Israel Used Palantir Technologies In Pager Terrorist Attack In Lebanon 2 weeks ago:
they maybe used it to get entry into hezbollah supply chain, and then for monitoring aftermath
and yeah this is a blatant lie:
In a recent interview, the former head of the Israeli Mossad, Yossi Cohen, revealed that Israel has similar “booby-trapped and spy-manipulated equipment” in “all the countries you can imagine”.
an attack that was a combination of supply chain infiltration, psyops (convincing hezbollah to ditch phones), surveillance (lending credence to the former), mass tampering, that got planned for a decade, took well over a half year to execute, and now will be useless because people know about it, and will try to mitigate (by looking inside), used as an one-shot chance against strategic adversary, but yeah there are thousands of phones with bombs in moldova, dude trust me
this is propaganda fluff for israeli nationalists

Tax reasons perhaps? In some countries ethanol with (certain kinds of) perfume mix can be taxed as denatured alcohol, otherwise some other kind of denaturant would be needed

for ccgt it’s more like 2/3 for gas turbine, 1/3 for steam turbine split, even more uneven for diesel/steam because diesel exhaust is much colder

as a citizen of a country whose government (-owned company) makes insulin, this reads weird to me

good. generic biosimilars cost like 1/5 of the on-patent thing price

I don’t think it’s a thing because even the same insulin analogue from different manufacturer can have different dosing

couple of reddit threads suggest that this is something you can do, but you have to be evasive around american border guard later if you go in person
- Comment on Insulin 3 weeks ago:
i mean i don’t think about it as a separate budget line because if you don’t have that you get police raids and investigation instead of normal business, but yea. insulin is purified using HPLC, so at all times you get some of analytical data about fractions you just made, so some of QC, not all, but already something, already happens at this point
my point is that actual manufacturing costs will be low because biotech scalability logic is that you need to make yeast or something that makes peptide you like and then all you need to do is keep bioreactor alive and happy. lots of what is left is in purification
also it’s an injectable so it’s gonna be kept to some standards that non-injected drugs aren’t
- Comment on Insulin 3 weeks ago:
there are multiple short-acting and long-acting insulins because you can’t patent other people’s things, but now it’s all off-patent. just take your stainless steel bioreactor and preparative HPLC, cook up a batch, wait ten years for biosimilar approval and you’re good to go
- Comment on Insulin 3 weeks ago:
I know not every state can or are willing to do this
this kind of thing scales well, i see no reason why after california has it set up, other states couldn’t get insulin from them, or chip in
- Comment on Insulin 3 weeks ago:
it might just be in glass vial and freezing broke it
- Comment on Insulin 3 weeks ago:
also european, but with some background: the problem is that there is natural (as in, unmodified) generic insulin available, it’s just that it sucks compared to everything else. you see, insulin is a peptide that is supposed to appear, do some signalling, then disappear and unmodified insulin copies this thing exactly. the problem is, most of the time, you don’t want to do that, you’d like insulin to last longer than usual, which means changes to it that make breakdown slower, or adding something that makes it stick to albumin, which has similar effect because it hides insulin somewhere enzymes can’t reach it. this means less frequent dosing and less changes in insulin activity over time. there are also other insulins that start acting faster than natural, and this is also due to a couple of modifications in its structure
for another example, ozempic was not the first drug in its class, it’s also a modified peptide, and it can be injected s.c. once a week, compared to previous iteration (liraglutide) that requires daily injections. if natural peptide is injected i.m. instead, its halflife is half an hour, and in serum it’s only two minutes (it gets released a bit slower than it is metabolized)
