    I've heard of déjà vu. I've heard of jamais vu, the feeling that you're seeing something you've never seen before. Is there a phrase for when you're sure you've been somewhere already but you're wrong?

    I felt sure that I, too, had posted about graupel on PriusChat, some time long ago. But my search now turns up nothing.

    Have we talked about the shapes of falling raindrops here? That's a fun one.

    All 'my' graupel melted.
    It seems to me that commercial snow-making operations (for skiing) actually make graupel, but I don't find an authority for that.

    US electricity production by sectors:

    US‘s wind and solar will generate more power than coal in 2024 - Ars Technica
    Electric Power Monthly - U.S. Energy Information Administration (EIA)

    I am surprised that it did not happen before 2024. For another country (my home) see:
    China’s EV growth: How a bet made decades ago is paying off big | CNN

    Figure far down on page shows %contributions. I expect coal % will not fall so fast by 2030 to 2035, but just me talkin'.

    ==
    Every country wisely would increase its electricity production in coming decades, but wisdom may come from how that is accomplished.

    the way these server farms are growing, and with bitcoin and now ai, i think we will be reopening the coal mines

    Interesting, but this news is really a what if.
    The new, higher amount of geologic hydrogen reserves is based a model that, "...makes no predictions about how or where this hydrogen is distributed in the subsurface. The authors note that much of it is likely too deep, too far offshore or in accumulations too small to be economically recoverable." The map the article is about places where this hydrogen could be trapped. Might be nothing there when the drilling is done.

    Maybe they can build AI centers directly over the hydrogen mines

    A Theoretical hydrogen mine. None have yet to be developed.

    Or do they all have yet to be developed?

    they could build theoretical AI centers over them

    Theoretically you can pull gold out of seawater. Even actually. The reason it remains more of a science experiment - like the practicality of hydrogen cars, it's way way too expensive to be practical, once you factor in all of the collateral infrastructure, r&d etc. Money better spent on the critical issues we are already failing miserably at as a nation.

    A few metal (ion) types in sea water come closer to plausible than gold. I recollect mentioning here desalinization brines as starting materials for extracting those. No idea if it is bring explored.

    There exist soil bacteria that bio accumulate gold. They may be under exploration to work on gold-mine tailings. They nota gonn na like sea salinity.

    US science funded by NIH and NSF* is now +/- shut down. I have not read if USDA, NASA, EPA among others are the same, but it would seem likely.

    University administrations typically are intermediaries between govt funding and actual research doers. Universities vary on how they are handling this, but some advise researchers to stop doing everything. There are some research activities that can take a break with little adverse consequences. Those with 'living biology' components (clinical trials, animal colonies, bacterial, fungal, viral growing among others) are in a pickle.

    *NSF, see:

    https://www.npr.org/2025/01/31/nx-s1-5282162/scientists-grants-frozen-trump-executive-actions-dei-deia

    With Kitt Peak Observatory as the sample image. This makes me wonder about several sky watch observatories that look for potential earth impactors every night. Those are things that may be rarely visible. Sure would be a shame if shut down forces a bad rock to go unseen.

    Let me stress that I don't know to what extent funds are frozen, you don't either, nor for how long. But most importantly, the funding recipients don't know. How much are we talking about overall? Below is Federal research funding for fiscal year 2022. A few are now a bit higher, others a bit lower, but pie slice sizes have not changed much. I would have made this for FY 2024, but Congressional Research Service website is now blocked to me. That seems a very recent change :eek:

    Sorry, serious misprint in the previous. Millions should be in all cases billions.

    Following my theme of 'anything is environmental if you squint':

    FDA approves first non-opioid pain medicine in more than 20 years - Ars Technica

    Suzitrigene acts on peripheral nervous system, so overdose will not stop lung function. that's a plus. Anything that acts on ion channels makes me think of snake neurotoxins but this molecule does not resemble those weird polypeptides. It does contain 4 fluorine atoms. Don't see that every day.
