True! I just wonder how much energy they'd realistically be able to store for a given amount of resources. I just wonder if this has the same issues as Lifted Weight Storage, where the energy density just doesn't really make sense once you get right down to it. I don't know the relevant math to determine how much water and at what pressures might be required to scale this up to the 500MWh/1GWh range. It might be perfectly fine.

I wonder if this suffers from the same power density issue as most alternatives to pumped hydro systems. It's REALLY hard to do better than megatons of water pumped 500 meters up a hill.

here you go

Yep, although using angle grinders can possibly destroy what's inside. UL does have much more stringent standards. To quote the Wikipedia article on safes:
TL-15 - This is a combination-locked safe that offers limited protection against combinations of common mechanical and electrical tools. The safe will resist abuse for 15 minutes from tools such as hand tools, picking tools, mechanical or electric tools, grinding points, carbide drills and devices that apply pressure. While the UL 687 defines this as a "limited degree" of protection, that standard is used for commercial applications, and the TL-15 rating offers significantly better protection than many unrated safes.

I love LPL, but he tends to focus on mechanical bypasses. I feel pretty sure that the safes mentioned in this article are actually listed by UL as safes. UL, of course, fucked up with the electronic locks themselves by underwriting them, but I have much more confidence in UL's mechanical expertise. The common bypasses that LPL uses would not be present on one of these safes, and he'd likely consider them to be truly secure (this vuln nonwithstanding, of course).

I thought I remembered reading that saltwater electrolysis is far more efficient than freshwater electrolysis. It's probably not orders of magnitude different, but I imagine it might help a bit.

Idk, they're probably fine. There are SO many instances out there nowadays, and I'd guess most of them are fine.

Anywhere but lemmygrad or hexbear, really. lemmy.dbzer0.com, lemmy.world, lemmy.zip, or lemmy.blahaj.zone are all good ones. I'm quite partial to kbin.earth (although you'd need a different app), and there's also piefed instances.
- Comment on Epic Games just won its antitrust lawsuit against Google again 2 weeks ago:
I don't like them because they took games that were perfectly functional on Linux and MacOS and made them not function anymore. I paid for Rocket League with the understanding that I'd be able to play it, and now I can't.

I'd be fine if property taxes were also tied to household income, with no exceptions being made for rentals. Like, raise my taxes and make my income bracket pay 100%, but reduce the property tax rate for households with lower incomes so they can stay in their homes. All taxes should be fair and progressive.

Taxes bad amirite? I mean, I wish my local school districts would stop doing stupid things, but I actually like paying for kids to go to public school.

Comments are the primary form of interaction on link aggregation sites. Most mod actions are performed against comments, not posts. The other way makes more sense to me, but who would want to post and then be unable to respond?
I feel that women should have an easily discovered place where they can talk about shit that is difficult to talk about online. Having the community show up in the All feed is the very best way to make it discoverable.
Like, if it's that important, there could be a !WomensStuffOpen that mirrors the other community but is open to comments from men. That feels fair and inclusive without taking away from women having a space for themselves.
- Comment on [deleted] 3 weeks ago:
Fucking exactly. Like, I blocked the community because I almost posted there several times without realizing. I didn't want to make extra work for the mods there, so I hit the block button. That's it, that's all it takes. The community should be public so women can easily find it. Blocking a community isn't an inherently negative thing, you should block stuff that isn't relevant to you. If you're good at remembering that you shouldn't post there and like to read the posts, then don't block it.
Would people be as upset if it was a community for gay men? I obviously can't know, but I don't think there'd be this much furor. Why is this so emotionally challenging for some people to accept? I can guess, but I won't do so here.

God fuck our coffee. I finally got an espresso machine somewhat recently just so I could have lattes like the ones I had in Europe. A good latte should not need sugar! Espresso should be yummy!
- Comment on [Gamers Nexus] The ASUS Dumpster Fire 4 weeks ago:
Yeah, it was a very foolish thing to do now that I know more. I was still a bit of a dumb kid though, and you'd think that their instructions would include something to that effect. Still, I wasn't really upset at them for that. I was mad because I spent months trying to get any form of support and simply could not.
- Comment on [Gamers Nexus] The ASUS Dumpster Fire 4 weeks ago:
I bricked an Asus laptop 15 years ago because their instructions on performing a BIOS update didn't include anything about what filesystem to use on the flash drive with the update file. I used NTFS (which was obviously a mistake in retrospect) and completely bricked the machine.
I tried calling their support line 30 times and never once got to talk to a human. I eventually just gave up on that laptop and replaced it with a Mac. I've been intensely sceptical of Asus products ever since then.
- Comment on Olympic casual GigaChad 1 year ago:
Your eye is still open under that flap though, no? I dabbled in Olympic pistol shooting back when I was doing across-the-course service rifle, and I was told to always keep both eyes open by the dude teaching me. Same for service rifle (and later palma). I always found that closing one of your eyes fucks up your focusing. If you don't have the little flappy dealy, you just do your best to defocus/deprioritize the view out of your non-dominant eye. I actually went for quite a while without any sort of cover because it helped me avoid cross firing (which is probably more of an issue with across-the-course than with Olympic pistol).
You're absolutely right about the lack of spectacles though. This guy is one hell of a marksman.
- Comment on We need this level of energy. All the time... 1 year ago:
Isn't this just a research grant? Plus, it's like, 11 million dollars. That's a shitton of money, but also an inconsequential amount of money when compared to the dogfuck tire fire that is the US healthcare system.
Like, I am regularly filled with rage at the stupid ways the US and various states waste money that could have paid for meals, houses, or hospital beds. I hate how we don't take care of people who need help. I hate that we all have to live in a place where rage like this is normal and accepted and reinforced, because it means we're all suffering under so much shit and all we can do is get angry. This video just makes me feel sad because it looks like a trauma response. I can empathize with and try to understand trauma, but I can't encourage it.
I just don't think a concept study for a train on the moon is the cause for our problems. I don't think it even represents the cause for our problems, because at least it's trying to look forward and consider/solve issues that humans will eventually face.
