Why is this in self hosted?

in case you want to self-host your own algae, I guess

[–] Jake_Farm@sopuli.xyz 9 points 1 day ago

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 like how everyone is acting like it is normal to have this in self hosted

[–] superkret@feddit.org 27 points 1 day ago* (last edited 1 day ago)

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.

[–] danielquinn@lemmy.ca 80 points 1 day ago (9 children)

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.

[–] A_norny_mousse@feddit.org 18 points 1 day ago

I appreciate Rebecca Watson's opinion. Watched the 6min video, now convinced 👍

Also learned a new term: kneejerk cynicism

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 51 points 1 day ago (1 children)

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

[–] halcyoncmdr@lemmy.world 31 points 1 day 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 32 points 1 day 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 1 day ago

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

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

[–] sorter_plainview@lemmy.today 18 points 1 day ago (2 children)

Try

docker run liquidtrees:micro-algae

[–] 9point6@lemmy.world 13 points 1 day ago

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

  1. Wrong community, maybe? Lol

  2. 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.

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.

[–] urandom@lemmy.world 27 points 1 day ago (1 children)

Trees don’t look cool

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.

[–] Rakonat@lemmy.world 13 points 1 day ago

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

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.

[–] Andres4NY@social.ridetrans.it 22 points 1 day ago* (last edited 1 day ago) (4 children)

@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!
[–] mosiacmango@lemm.ee 15 points 1 day ago* (last edited 1 day ago) (3 children)

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

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

[–] otacon239@lemmy.world 17 points 1 day ago* (last edited 1 day ago)

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.

[–] TORFdot0@lemmy.world 16 points 1 day ago (1 children)

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

Isn’t spirulina more effective for capturing carbon than trees? And also you can eat it in the way you don’t normally eat trees? Trees are great and all but why do you want me to be angry about algae?

Devil's advocate:

These cost far less to maintain than having a team or two dedicated to upkeep for the trees.

That said, these things are a terrible idea, clearly the brainchild of clueless techbros, and overall a massive eyesore. Trees are objectively the better option. Just not Bradford Pear trees... Anything but the cum tree.

I don't think your dog will see that as problematic.

[–] termaxima@programming.dev 10 points 1 day ago (1 children)

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)

I want to say deployment time is faster with the algae, you can also get hydrogen from the biomass
