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?
Gooooood Morning Night City!
Why is this on the self hosting community
Self hosting a tree
sigh take your upvote
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. 👍
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
Problem with VPFs is irrigation throttling, or lack thereof. Most people are cool, but I’ve heard of people hosting exotics which just max out downstream 24/7. Plus everyone has root access which gets abused frequently.
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!
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.
How long does it take to break even from the pollution and electricity spent to make and install these?

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
It’s just some circle of life stuff, fertilizer, carbon dioxide, light in, The algae produces more algae. It loads up on a bunch of carbon, some of the bloom dies off, by removing it, you take the carbon with it along with some of the fertilizer components. You add a little more fertilizer in and the algae blooms more and sucks up more carbon dioxide.
How much food and what is it?
…Did we mention it doubles as a convenient dumping ground for mob snitches?
Why is this in self hosted?
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.
It has a USB port.
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
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

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.

It’s not an either/or thing, the tank in the picture is literally sitting under a tree
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.
How’s my dog supposed to piss on that
I don’t think your dog will see that as problematic.
How do I self host these? I tried
docker run liquidtreesit didn’t workThey’re not stupid; its not in docker. Check apt.
Try
docker run liquidtrees:micro-algaeI think there’s an alpine build too if your system has low oxygen levels
Instructions unclear, installed Liquid Swords.
Not to worry, just make sure to change guid and puid to 1000 then restart the container
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 liquidtreesJust tried this and my DE got replaced with Sway and now there’s algae oozing out of my keyboard
Thats not a bug, thats intended behavior. Issue closed
Oh yeah, I put sway in depends for my own builds so I ensure it’s installed for new arch installs, oops
Nothing is wrong with trees, but the microalgae CO2 capture rate is 50x higher````` .
Their lifetime is also much shorter. Guess where all that CO2 goes, when they die ^^
I have a solution. More algae.
This is the solution. You drain it and sequester the carbon.
Based and algae-pilled
Fake and algae
Fertilizer
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.
This technique is controversial because there is limited understanding of its complete effects on the marine ecosystem,[5] including side effects and possibly large deviations from expected behavior. Such effects potentially include release of nitrogen oxides,[6] and disruption of the ocean’s nutrient balance.[1] Controversy remains over the effectiveness of atmospheric CO2 sequestration and ecological effects.
Geoengineering is bullshit proposed by funding from fossil fuel companies so they can continue to pollute.
The solution is simple: make it illegal to pollute. Fine the companies responsible for their past contributions to the climate catastrophe out of existence.
Not liquid enough.
