Their lifetime is also much shorter. Guess where all that CO2 goes, when they die ^^

[–] pikmeir@lemmy.world 19 points 10 hours ago (2 children)

I have a solution. More algae.

I'm gonna bet that you're going to get a much-more-economical return there by powdering whatever iron is used in building that thing and then dumping said iron powder into the ocean at an appropriate point.

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?
[–] pennomi@lemmy.world 48 points 12 hours ago (1 children)

Algae is also more efficient per cubic meter, if I understand correctly.

[–] halcyoncmdr@lemmy.world 29 points 11 hours ago

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.

[–] Dremor@lemmy.world 31 points 12 hours ago (4 children)

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.

Don't forget pollen and seeds.

[–] AustralianSimon@lemmy.world 12 points 11 hours ago

Bees need pollen. We need bees and you can self host them.

Bet that algae box will need maintenance too :-)

How do I self host these? I tried docker run liquidtrees it didn't work

[–] 30p87@feddit.org 2 points 7 hours ago* (last edited 7 hours ago) (1 children)

git clone https://aur.archlinux.org/liquidtrees.git && cd liquidtrees && makepkg
or
add https://repo.30p87.de/private/archlinux as a repo, and sudo pacman -Sy liquidtrees. Then sudo systemctl enable --now liquidtrees

Try

docker run liquidtrees:micro-algae

[–] 9point6@lemmy.world 11 points 11 hours ago

I think there's an alpine build too if your system has low oxygen levels

Trees grow and rip up the pavement around them. I do love the canopy though

@ECEC Good lord the number of replies here from people whose brains have been destroyed by "planners"...

  1. Trees lower the urban heat island effect.
  2. There's plenty of room for trees in dense places, so long as "density" means efficient housing and efficient transportation rather than parking lots and stroads and single-family homes.
  3. Someone said "trees require maintenance", as if asphalt & pretty much everything doesn't require maintenance?
  4. Trees harm cars. But cars harm cars too!

Trees are also essential for insects, bird and animal life in cities. They are psychologically calming for people as well.

There's plenty of room for trees in new dense places, sure. But if you're in the parts of London with old ass-narrow ass-streets, this may be less true.

Very cyberpunk

[–] MTK@lemmy.world 12 points 10 hours ago (3 children)
[–] Valmond@lemmy.world 8 points 9 hours ago

Looks more like MOSS.

[–] Flax_vert@feddit.uk 7 points 9 hours ago (3 children)

Trees are FOSS. This is a fork of trees.

The most dystopian thing I've seen... Fuck, idk, it's all pretty dystopian these days, I've lost count

[–] Zagorath@aussie.zone 16 points 11 hours ago (1 children)

Good post.

Wrong community.

[–] Cyber@feddit.uk 1 points 6 hours ago

Maybe, I'm self hosting several trees, so... 🤷‍♂️

[–] bluewing@lemm.ee 2 points 7 hours ago (1 children)

Yeah, those are going to last at -40F/-40C nights we often experience where I live. Nor do I see them being able to add any cool relief from their shade on a hot day.

That said, it is hard to grow healthy trees in the poisoned soils of a big city. They tend to struggle and be sickly when choked by concrete and asphalt.

Have you ever seen how long it takes for a tree to grow?

A big problem with trees is roots, especially in cities with dense underground infrastructure. If there’s an actual way to produce the same amount of oxygen as a tree in a smaller space, I’m all for it. I’m honestly okay with how these look, assuming low maintenance.
