Kwakigra,

Cyberpunk city with no plantlife other than these algae vats all over the place. Big towers of murky green liquid.

ThatFembyWho,

and they are fed by nutrients extracted from dead humans, because there’s no room to bury anymore and the air is too polluted for cremations

leggettc18,

To echo what some other people have said, these algae tanks absolutely should not be used instead of trees. If I see a tree get chopped down and replaced with one of these, I’ll be sad and angry. However, these can go in places where trees can’t go, like rooftops. And you don’t have to either wait for a tree to grow for a decade or take a tree from somewhere else to install one. It also serves as both a seating area and can mount a solar panel on top. These and trees both have their place and should both continue to be used.

millie,

Used for what exactly? To have a dirty fish tank?

JudahBenHur,

please god tell me you’re trolling

millie, (edited )

Nah, I just think it’s really silly.

If growing algae is effective at anything, why do it in a small sealed tank in the middle of a street? Most of the oxygen we breathe is produced in the ocean, regardless of where we personally are. Why would we need to stand vaguely near a rather sealed looking algae tank? If simply growing algae is effective for oxygen replenishment and carbon capture, surely we’d be better off simply growing massive ponds of it away from city centers? Like, out in the open?

It seems like green-washing bullshit to me.

Trees provide a lot more than oxygen. They provide shade, habitation for animals, and psychological well-being for humans. Dirty fish tanks don’t provide any of those things.

People are seriously in this thread complaining about roots like they’re a reason to replace trees with algae boxes. Getting some big plant-based NFT cryptobro carbon-credit nonsense vibes.

DragonTypeWyvern,

It’s actually hilariously ignorant that you people are pretending this is a cost effective idea for carbon capture. It will, in fact, just make a bunch of dirty fishtanks that are abandoned or thrown away almost immediately.

JudahBenHur,

thanks for calling me you people dude!

who said it was cost effective? I only said I cant believe this person didnt get the idea.

its not “in fact” its “you believe” . youre probably right, just saying

leggettc18,

For the conversion of Carbon Dioxide into Oxygen? That was the main point of these, the algae does that and is actually even more efficient at it than a tree. Trees do have other benefits hence why they shouldn’t be replaced, but these should go in places where trees can’t.

millie,

That is adorable.

frezik,

Putting a ton of water on the roof isn’t a good idea, unless it was already rated for a swimming pool.

They don’t need to be inside cities at all.

CCF_100,

SciShow made a video about these: youtu.be/QUGJPZ1a308

@DrDominate@lemmy.world avatar

That is super cool and my immediate assumptions were dispelled. I would love to see these in my city.

MeatsOfRage,

Thanks for posting this! I was curious about this and had to scroll through so many miserable comments in this thread to find this.

eltimablo,

For real, the people on this site deserve the hell they create for each other. If Kbin had a functioning account delete button, I'd have been gone months ago.

Blademax,

It’s coarse, and rough, and irritating, and it gets everywher…wait…that’s sands… Nevermind…

gerbler,

I think a lot of these are just cool experiments and projects grad students do for the sake of doing them. Then some hack writes an op ed about how we don’t need to worry about deforestation because we can plop algae tanks down instead.

WetBeardHairs,

Oh thank god. We don’t have to worry about deforestation anymore? Phew. Thanks, tank of algae.

anarchy79, (edited )
@anarchy79@lemmy.world avatar

Sadly, dealgaeation is quickly becoming a catastrophic problem. However, we are confident we can soon genetically modify human lungs to partially breathe the sulphur clouds that will engulf our planet!

Baphomet_The_Blasphemer,

I thought it was more of an experiment that, if proven successful, could eventually aid in the exploration of space since we would need to engineer ways of creating oxygen for prolonged travel.

smiling_big_baby_boy,

We are in a parasitic relationship with capitalism. Capitalism constantly extracts from life and the environment. When life begin to limit captialism, capitalism will go to great ends to remove life. Capitalism is not sustainable, nor is it naturally occurring. Abolish this evil system.

WetBeardHairs,

How about we only have some capitalism. Let’s only allow less slavery and habitat destruction in exchange for us all to be subservient to billionaires.

2deck,
@2deck@lemmy.world avatar

Okay, you get 5 capitalism. But you have to share.

pelerinli,

What are you, a communist?

TipRing,

While it’s good to be skeptical, algae tanks like this are actually a good idea for the use-cases for which they are designed. Places where trees would be difficult and expensive to grow. The tanks more efficiently capture carbon, require less maintenance, produce fertilizer as a byproduct and the solar panels on the tank produce enough extra power for there to be a USB charger on the bench. The goal isn’t to replace trees with tanks but to use them where it makes sense to do so.

ridethisbike,

This was my thought as well. They should be used in addition to, not as a replacement for, trees, bushes, and grass.

It does make me wonder, though, whether or not we could use these to help capture more carbon than we’re creating.

Sanyanov,

That would require a gigantic scale of operations, and trees are just waaaay more economical.

Think of entire oceans full of algae not being enough to stop what’s currently going on with ecological situation.

anarchy79,
@anarchy79@lemmy.world avatar

Too expensive to grow trees? Thank god capitalism is saving us so much money, we are all so rich now that we can simply buy oxygen tanks instead of having to deal with those money sucking trees and plants.

iamnotdave,

Because they pick trees that have gender. They plant male trees, see dogwoods, the flower but not bare fruit. So you get allergies because of tree cum. And as far as I know plankton cum doesn’t come with side effects.

CoffeeJunkie,

I’d have to see how it is better than, worse than trees on a case-by-case basis. But generally speaking, I can think of a few reasons this is better:

Trees are messy. They take a long time to grow, they take constant maintenance while growing, then they eventually die. Tree roots fuck up pipes & concrete. If this installation is equivalent to 1 or more trees, it is doing the work in a fraction of the space.

CiderApplenTea,

At the same time, though, green space has shown to improve mental health. I would be curious (and very sceptically biased) if algae tanks have the same impact.

@driving_crooner@lemmy.eco.br avatar

Trees also provide shadows and space for birds and other animals.

uis,
@uis@lemmy.world avatar

They are too good

NabeGewell,
@NabeGewell@lemmy.world avatar

Imagine replacing trees with those, and some drunk breaking the glass like once a week lmao

rosymind,

That was my thought as well. I’ve seen what some homeless people are capable of. (Not trying to dump on unhoused people, here, but there are some seriously ill people left out on the streets). This glass needs to be nearly unbreakable for it to work

anarchy79,
@anarchy79@lemmy.world avatar

Not to mention what ordinary pub goers can do!

candle_lighter,
@candle_lighter@lemmy.ml avatar

The answer is trees take years to grow and aren’t suitable in places like rooftops

LoamImprovement,

Also, trees that get too big have roots that damage infrastructure and have to be cut down. I’m not saying I like the dirty fishtank look more, but I can see how this might be easier to maintain in urban spaces.

uis,
@uis@lemmy.world avatar

It is fucking street

candle_lighter,
@candle_lighter@lemmy.ml avatar

And you can’t grow trees on concrete. This one is particular is just the first one of it’s kind and it’s mostly in a spot to show off the technology. I’m not aware of any other ones that have been built yet.

anarchy79,
@anarchy79@lemmy.world avatar

That’s why there are no trees anywhere in cities, and roofs never have plants anywhere.

ILikeBoobies,

Algae should be more effective and pollution kills trees

uis,
@uis@lemmy.world avatar

Pick metric for efficiency

frezik,

CO2 absorbtion rate over time. It’s not even close.

That said, trees have other benefits in an urban setting.

uis,
@uis@lemmy.world avatar

CO2 absorbtion rate over time.

Educated person found.

That said, trees have other benefits in an urban setting.

Yes. It is easier to notice burning skin than different CO2 level.

anarchy79,
@anarchy79@lemmy.world avatar

We are not replacing trees with green sludge canisters. I’ll take up weapons way before that.

radioactiveradio,

Can’t wait to see hulk semen cartridges everywhere when I go out for a walk.

the_post_oftom_joad,

HULK SMASH CO²!

Hiro8811,

Huh?

mycatiskai,

They are saying these day glo green containers look like the incredible hulk ejaculated into glass boxes on the street.

Hiro8811,

Ahhh. There was no capital H so I got confused.

TheBat, (edited )
@TheBat@lemmy.world avatar

HULK SMASH?

RememberTheApollo_,

Trees offer real world benefits of carbon reduction, temperature reduction, shade for people, the psychological benefits that trees offer, some limited wildlife habitat, and they do it without much outside help. They grow themselves with decent maintenance.

But you have to build and maintain this tank. What carbon was used to do so, and what maintenance will it need. Can it offset its own cost? It offers no benefits to wildlife, no shade, no temperature reduction.

Yeah, trees leave leaf litter and can heave sidewalks with roots, but given that neither system is perfect, there’s no reason to argue that boxes of algae are better.

ook_the_librarian,
@ook_the_librarian@lemmy.world avatar

Why do we need to argue which is better? In some places, beautification isn’t really practical, but you can still stick these around. They don’t look hard to install or uninstall, unlike trees.

I would hate to see a tree actually replaced by one these. But no one but the meme is saying that is the plan.

anarchy79,
@anarchy79@lemmy.world avatar

I think we have reached the limit for how much we should “improve” and replace nature, if there’s no room for trees we should make room instead of accomodating yet another industrial solution to a problem created by industry in the first place.

We’re going in the wrong direction.

uis, (edited )
@uis@lemmy.world avatar

carbon reduction

Mostly indirect.

Also trees dampen noise

Can it offset its own cost?

I guess.

there’s no reason to argue that boxes of algae are better.

Depends on metric of choice. Still I would prefer trees.

EatYouWell,

Algae is actually much better at capturing carbon than trees are.

anarchy79,
@anarchy79@lemmy.world avatar

We are just fine with the trees though, thanks.

Meowoem,

So you’re a climate change denier? You don’t think we need to worry about co2 levels?

Or is this just a knee jerk unthought responce because you hate science and technology?

EatYouWell,

Except we aren’t. And trees are awful for urban areas from an infrastructure standpoint.
