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

Don’t sit under the algae tank with anyone else but me… anyone else but me… anyone else but me!
JimVanDeventer@lemmy.world 11 months ago
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?

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
0ops@lemm.ee 11 months ago
It’s not an either/or thing, the tank in the picture is literally sitting under a tree
Guenther_Amanita@slrpnk.net 11 months ago
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!
TORFdot0@lemmy.world 11 months ago
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
hazl@lemmy.blahaj.zone 11 months ago
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.

Why is this on the self hosting community

Its apart of a Watercooling setup

self hosting is anti-capitalist, so is being against urban brutalism.

The most dystopian thing I’ve seen… Fuck, idk, it’s all pretty dystopian these days, I’ve lost count
bluewing@lemm.ee 11 months ago
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.
jagged_circle@feddit.nl 11 months ago
Oh thats why the box below it provides heating and cooling. Its powered by a gasoline generator.
bluewing@lemm.ee 11 months ago
Do you want to pay for the heating and cooling of a bunch of those tanks out of your pocket? Or even the cost of upkeep to keep the tanks clean?
Capricorn_Geriatric@lemmy.world 11 months ago
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.
exedore6@lemmy.sdf.org 11 months ago
Roots limit where they can grow without messing up infrastructure.
Dozzi92@lemmy.world 11 months ago
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.
ArcaneSlime@lemmy.dbzer0.com 11 months ago
- 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 shad
Good.
- Animals like birds and insects like bees and mosquitos like to live next to them
Good.

Bullshit.

CheeseNoodle@lemmy.world 11 months ago
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 11 months 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

I don’t think anything’s wrong with trees, but maybe we could also have some of these as well as trees ?
First of all nobody is proposing to replace existing trees with that, that would be silly!
And yes, that’s pretty much the idea: install these in densely packed cities that are already highly polluted to start truning things around. Rebecca Watson’s 6min take
danielquinn@lemmy.ca 11 months ago
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.
lightnsfw@reddthat.com 11 months ago
How long does it take to break even from the pollution and electricity spent to make and install these?
FarceOfWill@infosec.pub 11 months ago
It provides fertilizer but needs “some food”.
How much food and what is it?
rumba@lemmy.zip 11 months ago
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.

…Did we mention it doubles as a convenient dumping ground for mob snitches?

Depends on the variety of course… my Willows need cutting down, whereas the acorns I planted before the willows are still tiny oaks in pots 🙂

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.

Trees grow and rip up the pavement around them. I do love the canopy though
jagged_circle@feddit.nl 11 months ago
Line the plater with steel, and this is not a problem. Bonus: trees are dwarfs and don’t present risks of falling on structures in storms.
Valmond@lemmy.world 11 months ago

… with damaging infrastructure? Well, presumably the infrastructure will no longer be as good at serving its original purpose once it is damaged.
xor@lemmy.blahaj.zone 11 months ago
It makes it difficult to use the pavement for what it’s for, especially for elderly people and people with disabilities, costs the council a bunch of time and money to repair, and doing the repairs often require killing off the tree

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.

tal@lemmy.today 11 months ago
As I recall, at least under US law, you can’t copyright genetically-engineered life, just get a twenty year biological patent. So I don’t think that FOSS status would be directly germane other than maybe in how some such licenses might deal with patent licensing.

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.
jagged_circle@feddit.nl 11 months ago
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 contributions to the climate catastrophe out of existence.
