Hard disagree: they exhibit 4 perfect octahedral cleavage planes in addition to their adamantine lustre, diamond is one of the most useful materials in existence, and their petrological origins speak to incredibly interesting conditions of formation! In fact, a mineral inclusion within a diamond gave us our first solid evidence of the existence of water at equilibrium with mantle rock at depth on Earth, which was previously largely discounted.
But yeah, fuck De Beers.
Alright, now we agree: solar isn’t for everywhere, and the gravity storage method won’t work in most places. You need preexisting slope, and my original comment was highly US-normative. As such, yes, we would need huge swathes of solar and wind collection sites, passive wave generators, pumped hydro and, yes, perhaps nuclear. Not everything will be “on” all the time. As far as the energy vs. Electricity numbers, while I vacillated between different terms, I WAS quite careful to only include electricity numbers throughout my stats and, again, none of my points were trying to prove that solar, specifically, is the right answer for the netherlands in exclusion of all else, but only that a significant energy storage problem can be solved with gravitational potential, and that the solution IS scalable if sites are selected carefully, and the fact that this has not been tried at scale anywhere in the world is due to government corruption. Still a US-normative idea, which I’ll grant, but still true, when you have places from morocco to the Gobi, to the outback to the western US, all with significant natural elevation change, significant open areas, and excellent prospects for renewable energy sources of ALL kinds.
Also, as far as solar panels go, remember that actual diode solar panels are NOT the only way to harvest solar energy (let alone the cheapest). Mirrors can easily be used to boil water, and this plan was nearly attempted throughout egypt a hundred years ago (see Frank Shuman’s solar thermal generators). However, I’m not about to argue that we should put giant solar collectors in one of the countries that is simultaneously the most population-dense (3rd highest in europe, IIRC) AND in a climate where large-scale solar is somewhat inefficient, ESPECIALLY when you have so much available wind power.
That’s interesting. For me, I guess it’s a “grass is greener” scenario. I look at the headway various countries in the eurozone have made on topics from socialized medicine, to universal basic income, to free postsecondary education, to the protection of personal data, and even to forcing Apple to change its charging cable to the standard USB-C. That change of policy forced them to change it here, as well. The EU’s stodginess helps people even beyond its borders. My students ALL have iPhones, and It’s unbelievable to witness the ease with which they can access their devices now, vs. when they were all forced to use a specialized cable for connection and charge. America hasn’t even figured out high-speed rail yet. As an american who teaches secondary science to a bunch of naturalized citizens under the age of 18, I don’t think I can stay through the next 4 years. I fear the pogroms, if not for myself, then for my students and their families. I can’t have my tax dollars go towards a repeat of the mistakes of 90 years ago. I’m thinking New Zealand is looking comparatively nice (though apparently there’s a growing nationalist movement there as well).
In general, I do sense that there is a significantly greater sense of “rugged individualism” in the US, compared to many other countries, but I see the costs of that individualism more acutely because of its proximity. People seem to be largely incapable of consideration here, from anti-vaxx and anti-mask movements to the hesitance to tax the wealthiest individuals due to the thought that “maybe that’ll be me one day”. It’s really quite distressing.
And hey, you know what, that’s almost got a point. Firstly, I’m in the US, and I’ll freely admit that my comment was highly US-normative. However, I believe my comment on government corruption stands for the US case, where there is an insane amount of space that is already partly-developed in random bits of desert.
Now, let’s get into your claims against the Netherlands case. Let’s do some “basic maths”:
Quod Erat Demonstrandum.

ETA: rectify a quote (“just 1 small country”), and make it more civil in response to the prior commenter removing some of their more condescending language.
Again, a fair point. Assuming that anyone with an idea of the meaning of “potential energy” survives the next ten years, I’d still like to see it more fully explored in the american west, but it is, unfortunately, rather a moot point for at least five years.
I agree with you on the linearity issue. I just feel like using its size as a criticism is invalid, given that the very source you cited pointed out that the reason it’s so small is because they chose to reuse an already-disturbed site, rather than building it on 100 acres of BLM land, which I’d argue is quite admirable. The colocation point is also fair, though our water resources in the entire american west are severely limited, and will become moreso over the next 50 years. Utah’s declining snowpack and the overdrawn Colorado can only cover so much. I feel like, while the GPE law is linear for both mass and height, the fact that we can scale both is a point in favor of both pumped hydro and rail storage, and rail storage can be stored virtually indefinitely, as long as it doesn’t have time to rust in place. Being able to supplement the off-hours is absolutely doable with rail.
A fair point, but given how the best places to build solar infrastructure tend to not have easily accessible large volumes of water, I should think that economies of scale can apply if we were to put actual investment into scaling up the gravitational potential. Sure, it’s not a geometric law like for kinetic energy, but greater height and greater mass are both trivial quantities to scale in places with large empty areas. I’m simply pointing out that we’ve never invested in that obvious possibility as a civilization. Am I missing something obvious that makes the scaling non-viable?
I feel like we’re missing the part about “push carts up a hill”, which involves virtually no serious engineering difficulties aside from “which hill” and “let’s make sure the tracks run smoothly”. See: the ARES project in Nevada
Let’s be clear, the only reason grid-level storage for renewables “doesn’t exist” is because of a lack of education about (and especially commitment to) simple, reliable, non-battery energy storage such as gravitational potential, like the ARES project. We’ve been using gravitational potential storage to power our mechanisms since Huygens invented the freaking pendulum clock. There is simply no excuse other than corruption for the fact that we don’t just run a couple trains up a hill when we need to store massive amounts of solar energy.
Yeah, the only reason I replied was because you were responding to the calcium dude above, then said “s-block”. Just wanted to spread the good word of the 9th-most abundant element in the universe 🙏
Magnesium is fine (see response above). https://invidious.darkness.services/watch?v=Q_4I30Nz_b0 Just don’t vomit on it before you lick it, 'cause it’ll get spicy with acid.
I have elemental magnesium (4 ~50g ingots, I keep it in my library in a barely-sealed ziplock). it’s shelf stable and doesn’t react violently with water. Want me to try licking it and let you know? (hint: at worst it’ll make a minuscule amount of milk of magnesia)
ETA: Would I stick my tongue in pyrophoric magnesium powder? No, and you wouldn’t do that with pyrophoric aluminum or zinc powders, either, but that doesn’t stop me from using (or licking) alumnum foil. Proof: https://invidious.darkness.services/watch?v=Q_4I30Nz_b0
To be fair, Coelacanth, I don’t think you’re a normative judge of the passage of time.
