Pinkerton was the only good Weezer album

Just remember folks. You can always just wear an n95 around. If any one asks just say you have ass covid.

Who would have EVER known…

I’d probably install it in that case. Like a dark mode.

Port was already in use?

Every accusation is a confession.

Ahem…

Sure, but its like, way, way way easier to scale a hydro system.

Yes, I agree. I’m just making the point that there isn’t just a lower limit to the scale for a system like this, but an upper limit too, where you would have been better off just building a dam.

I mean you are more than welcome to make that not the case. The git hub repo is right there. Fork it and make it your own.

Energy density has nothing to do with this.

No it absolutely does, and it matters because:

It’s the cost of how much pollution refining the rare earths and making batteries produces vs the amount of pollution associated with construction of a building with pulleys that move weights up and down.

If an entire building could be supplied with a few elevator shafts and some weights, because the energy density of the system is so high, it would be silly not to do so. But the energy density of these systems isn’t remotely close to that. Where as yes, a building absolutely can be built with batteries as a part of it to support its typical duty cycle.

Gravity is just not a particular energy dense form of storage. Its not really debatable. And like you said, building buildings comes with all kinds of other forms of pollution. Not to mention, we could be building them to house people, not pulleys and weights.

Its an idea that sounds good, but once you engage with it seriously, its limits become obvious. Pumped hydro will almost always make more sense. A big tank at the top and a big tank in the basement, and bam. Battery built. not to mention you’ve got a semi-permanent back up reservoir now built, which could help with flood control, drought tolerance, fire control, all kinds of other things. And you don’t need to build new buildings for this. They can go into/ on existing buildings.

Its a design choice that is central to how the infrastructure of the fediverse works.

And I disagree with your second statement.

That display is dependent on your view into the fediverse. If it was deleted on your instance, yes. If viewed from a different instance, not necessarily…

Pumped hydro almost always will make more sense because, for one, we’ve got pumps and pumping, and water storage VERY figured out. And water storage, well. Thats just a great co-benefit to have from the system.

it only makes sense if you do it at large scale

Or rather, it specifically might NOT make sense at scale. It might only make sense in middle scales, where there isn’t a topographic advantage to use, but the requirement is more than batteries can support.

I can’t imagine environmental impact would be worse than mining and refining rare earths for regular batteries here.

I mean it depends on the energy density. Where the batteries go. Can they be just “slapped into” existing infrastructure? Can they rare earths be used effectively indefinitely once mined, and on and one and on.

An inability to imagine isn’t a form of evidence.

Thats a pretty fucking big on. Also, the technology to “turn a wheel” to create electricity… pretty fucking established.

And… god forbid, if the community you are in ends up needing water more than electricity, well, you’ve got a bunch stored and ready for other uses.

savings that fall out of it naturally.

sigh… Buh dim tish.

On the topic, I really doubt it’s about savings at this scale, which is very much proof of concept. I mean it could be but at this stage it’s more important to show it’s potential. And for some thing that’s gonna run for thousands of cycles…
