I want to say deployment time is faster with the algae, you can also get hydrogen from the biomass
Let’s go for a walk in the park - they just cleaned the algae tanks!
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!
Algae in water doesn’t burn like trees
Checkmate commies !
It sounded cool a couple of years ago, but it was first installed in 2021 and I’m yet to hear of it really going anywhere.
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
It’s not an either/or thing, the tank in the picture is literally sitting under a tree
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 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.
Not liquid enough.
Elon musk going into the tree business I see.
Why is this on the self hosting community
Its apart of a Watercooling setup
Self hosting a tree
sigh take your upvote
We’re gonna go ahead and merge the gardening community with this one 😌
self hosting is anti-capitalist, so is being against urban brutalism.
I can kinda see that, yeah. 👍
The water is hosting algae
Looks like one of them fish tank PC cases that are apparently a thing.
The most dystopian thing I’ve seen… Fuck, idk, it’s all pretty dystopian these days, I’ve lost count
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.
Oh thats why the box below it provides heating and cooling. Its powered by a gasoline generator.
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.
Yeah this is a big problem I see often. You have underground utilities? Tree planting becomes a huge thing. And in a lot of these walkable areas, places you’d want trees, folks tend to also prefer not to have the wires overhead with telephone poles everywhere, and so they’ve been backed into a corner.
I did just sit through a presentation by my local environmental commission where they addressed the issue. The solution seems to be trees bred for the specific environment: deciduous provides shade but doesn’t drop a lot of leaves; can grow tall but the root ball grows in a certain way so as not to interrupt sidewalks and utilities; hearty and resilient. I can’t recall the trees, but they were described as essentially not naturally occuring.
Ginkos are very common. They’re ancient trees, and almost went extinct, but they’re tolerant of the rather extreme conditions of an urban environment and very pollution resistant
- 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.
Trees don’t look cool
You take that back!
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
