So I think the general idea is that you can convert more CO² to carbon in the form of sugars and O² molecules per square foot with algae than with trees. Trees would totally do the same thing if we ripped up all the concrete and buildings to replant a forest, but that process would take decades.
This can be added into existing infrastructure and helps I guess. Kinda a neat concept.
Shade, cooler Air in summer, better protection against rain… 🤷♂️ Trees are 😎
Exactly man… fewer floods, more biodiversity, they look nice which is better for mental health and reducing hypertension (the number one risk factor correlated with deaths), some of them give you fruits or nuts to eat… Trees are awesome.
I think any city should strive to have at least as many trees as the number of people living in it.
…if we ripped up all the concrete and buildings to replant a forest…
You say this like it’s a downside, we’d better get started!
It would be. Cities and urban areas aren’t the problem. Suburbs, with 20+ Minute commutes, on hot swollen rivers of concrete and asphalt flowing from them, with every individual in their own metal/polymer box burning hydrocarbons is the bigger problem. Cities might be a solution.
Conversely these algae tanks can go lots of places a tree wouldn’t be practical. They’ll never need to be trimmed out of power lines etc. Or tear up sidewalks, streets or foundations. That’s not to say we shouldn’t have trees. Just more green overall.
But why not just like… Do that somewhere where the mass actually makes a difference? You’d be better off dumping acres full of this shit instead of regrowing a forest. Doing it in individual tanks, sparsely within a city, is both an inefficient use of resources and fucking ugly.
Trees only purpose in a city is not to clean out CO2. It’s not even their primary purpose in a city. If it was, they’d be selecting specific species etc.
I mean ideally we would flood the ocean with Fe³ and spark a mass breed of this shit where it belongs. The biomass could work it’s way up the food chain as an added benefit too.
But we won’t 🙃
If history taught us anything it is that purposely messing with an ecosystem seldom has the effect we want to achieve.
Alright I’m just going off of what I learned in environmental science class this summer, not an expert here. There was something about algae blooms (usually caused by fertilizer runoff) being a really bad thing for local ecosystems. I’m not sure if this is relevant to what you’re saying, just throwing it out there lol
If they didn’t just breath oxygen and give off CO² at night, maybe, but trees actually undo much of their oxygen creation overnight… 😅
On this note, think of all the benefits if we filled all our public swimming pools with algae!! I’m sure nobody would notice the difference
I saw something like this, which piped exhaust from a generator thru a container of water and algae, with the idea to capture the co2, etc produced. Sure why not. I’ll still prefer trees.
I’ll still prefer trees
God, yes. Trees provide shade, transpirative cooling, homes for animals (birds, mammals, insects), and a particular natural beauty that tanks of algae do not.
Trees are too useful so we keep cutting them down
Nobody uses an urban tree that gets cut down. It just gets hauled off to the landfill.
It’s absolutely ludicrous that when the gigantic oak in my yard fell the arborist didn’t know of anybody who could cut it up into lumber for me – even in a city with so many urban trees that it’s called the “city in a forest” – but allegedly the economics of it don’t work out, or something. I dunno if that’s true, but it pisses me off enough that I’m half-tempted to go buy a damn portable sawmill and start a business doing it myself.
Say that to the table in my living room. (They removed a lot of old exotic trees that were lining some road some years back, those trees got sold to people making nice tables).
Selling the trees was only a side effect, and these weren’t your run of the mill trees either. But exceptions exist
This doesn’t have a root system to worry about so it needs less underground space. Don’t get me wrong I love me a good tree, but in places where there isn’t enough land for roots to spread this could be useful. Lots of side walk trees die due to not enough space for the roots
Trees have trouble in urban areas with a lot of traffic
