Why is this on the self hosting community
The water is hosting algae
Looks like one of them fish tank PC cases that are apparently a thing.
self hosting is anti-capitalist, so is being against urban brutalism.
I can kinda see that, yeah. 👍
homeless people find sitting in the shade of trees to be comfortable, and the city whole point of urban design is to make them uncomfortable and to suffer
I think it’s probably cheaper in the long run to self host a tree instead, unless you live in an apartment with absolutely no green space. But I’d rather get a VPF and host a tree there if I had too
Does this count too?
I already posted this on !balconygardening@slrpnk.net. .
I’m purposefully growing duckweed on my balcony.
I’m doing !hydroponics@slrpnk.net, and by doing that, I have lots of waste water with still good fertilizer in it.Duckweed is one of the fastest growing, nutrient densest and least demanding plant out there, and you can just scoop it out with a strainer.
It’s exponentially growing and if you don’t wanna eat it, it makes great organic fertiliser or animal feed with lots of protein and micronutients!
It’s not an either/or thing, the tank in the picture is literally sitting under a tree
I had the same reaction until I read this.
TL;DR: it’s 10-50x more efficient at cleaning the air and actually generates both electricity and fertiliser.
Yes, it would be better to just get rid of all the cars generating the pollution in the first place and putting in some more trees, but there are clear advantages to this.
I appreciate Rebecca Watson’s opinion. Watched the 6min video, now convinced 👍
Also learned a new term: kneejerk cynicism
It provides fertilizer but needs “some food”.
How much food and what is it?
Typically for aquariums you have to feed these things fertilizer so it seems odd
How much food and what is it?
…Did we mention it doubles as a convenient dumping ground for mob snitches?
Short answer: the bank won’t give your shiny new tree-planting business a loan as easily as it will to a “liquid tank tree replacement” one.
Long answer:
- Trees take time to grow
- Trees need to be planted
- Trees make shade
- Animals like birds and insects like bees and mosquitos like to live next to them
- Trees don’t need electricity
- Trees take in heat radiated from the pavement
- Trees don’t look cool
While algae are more efficient at turning CO2 into oxygen in theory, in practice algae don’t have a good climate in such a tank (no oxygen without ventilation, i.e. constant electricity and they get cooked through the glass).
All in all, more of a gimmick than anything.
Roots limit where they can grow without messing up infrastructure.
Trees don’t look cool
You take that back!
was about to furiously reply with the same retort… but yeah. I LOVE green spaces
- Trees take time to grow
Sure, of course not removing literally all of them in the first place is preferable but hindsight is 20/20 I guess. And good things come to those who wait.
- Trees need to be planted
True, planting a tree seems a bit easier than installing a weird tank though, despite time to grow.
- Trees make shade
Good.
- Animals like birds and insects like bees and mosquitos like to live next to them
Good.
- Trees don’t need electricity
Good.
- Trees take in heat radiated from the pavement
Good.
- Trees don’t look cool
Bullshit.
Aren’t like half of those bullet points positives? Also in addition to what you said once you got a tree you got a tree, those tanks need constant maintenence and cycling which I doubt anyone is going to bother with for more than a year after installing them.
The comment you replying to was trying to not so subtly point out this is a business plot and little else. Nobody is going to pay a subscription fee to have a tree in front of their business, but they might cough up money for a third party to maintain a tank of algae out front if it was sold right

Not liquid enough.

Wrong community, maybe? Lol

iirc, algae are better oxygen producers per units of mass and volume, so a tank full of algae might actually be better than a tree. One issue though is that trees can grow on open ground, while algae require a tank to be built, most likely negating the economic benefits. Also, trees are more aesthetically pleasing.
What? You don’t like future jelly tree?

Why is this in self hosted?
It has a USB port.
in case you want to self-host your own algae, I guess
Can I combine this with my water-cooling setup?
Just give me a 4U tank somewhere where someone else can deal with harvesting the algae and a webcam aimed at it and I can enjoy it just fine from here. For me, selfhosting is mostly about the privacy, not principally about needing to be resistant to loss of Internet connectivity or the like.
I have seen a few guides on growing your own algae including from CodySlab.
Come on, you know there’s someone out there trying to work out how to selfhost one of these.
I have a birth bath I don’t ever replace the water in. Its like a shrub to me.
birth bath
Uhhhhhh you should probably at least drain out the placenta fluid…
No, it’s essential to the flavor.
You should look up “Walstad planted tank”. An all plants aquarium you don’t ever have to mess with (except to trim if you want to)
How’s my dog supposed to piss on that
I don’t think your dog will see that as problematic.
I like how everyone is acting like it is normal to have this in self hosted
I love this about lemmy.
Like someone stumbling into the wrong house and still being welcomed.
It’s a lot more informal and relaxed than on the piss page of the Internet.
I don’t think anything’s wrong with trees, but maybe we could also have some of these as well as trees ?
Replace the advertisements on bus stops with a really cool green liquid wall 😮 (but they’d have to make the glass super thick, these things tend to be vandalized from time to time)

First of all nobody is proposing to replace existing trees with that, that would be silly! AFAIU the people who created this also don’t want these to be used where trees could be planted. They are outspokenly designed for already densely packed cities that are already highly polluted and hostile to trees, to start turning things around. Rebecca Watson’s 6min take
Practical answer, fits in places trees may not. Pessimistic answer, fits in some guys cyberpunk ass vision for what he wants his office block to look like.
Because there’s no serious answers being given even though there are at least 2:
- trees have roots, roots ruin any nearby human infrastructure. You’ll note this says “in urban environments” and that there are trees nearby, so this is probably the big reason
- trees need maintenance, which costs money. this is a stupid reason imo, but it’s one nonetheless
- algae is cool, ok?
Algae is also more efficient per cubic meter, if I understand correctly.
Not just more efficient, vastly more efficient. Algae is 10-50 times faster at processing CO² than trees are. Some algae can be up to 400x as efficient.
It’s just not as “nice” to look at, we usually associate algae with growth in unsafe bodies of water like bogs, etc. versus a nice clean pool or even a maintained pond.
On the other hand, algae do not produce shade, not sure if it filters atmospheric pollutants, and trees provide all sort of other services to the local ecosystem.
Maybe this invention can be used on places where trees cannot lives, but I’d still take a city with trees over a city full of green tanks.

These in the spots where trees once stood but were too destructive & trees everywhere else imo. Cool tech future AND trees, plus these are benches too it looks like

This part is the most surprising. For something meant to go in urban areas, where’s the hostile architecture? No railings between seats? No spikes?
That sounds like it needs its own community. “Hostile Architecture” I love it.
Edit: I googled the term and think it could be a sub. https://www.re-thinkingthefuture.com/designing-for-typologies/hostile-architecture-anti-homeless-architecture/
(Sorry, you made me think of this article)
Don’t forget pollen and seeds.
Bees need pollen. We need bees and you can self host them.
Oh yeah
I’m one of those elites who don’t have allergies so I tend to forget 😎😎😎
>:(
Let’s tie him up and sneeze on him.
Plus pollen means having to pay to clean it off.
Bet that algae box will need maintenance too :-)
“let’s uproot all these trees and invade this space. and when the roots of the few remaining trees do what they are supposed to do, let’s blame them for ‘ruining’ human infrastructure!”
trees dont ruin ANY human infrastructure. But the usual urban infrastructure isnt well thought out enough to exist around trees. But smarter urbanism is possible and in fact does exist.

I think you mean all, as this reads more like “nuh uh, trees don’t ruin anything”
But smarter urbanism is possible and in fact does exist.
And those are not the norm, so for places that don’t plan to just destroy what’s already there and start anew, this is an option
People ruin nature’s infrastructure
