While it’s good to be skeptical, algae tanks like this are actually a good idea for the use-cases for which they are designed. Places where trees would be difficult and expensive to grow. The tanks more efficiently capture carbon, require less maintenance, produce fertilizer as a byproduct and the solar panels on the tank produce enough extra power for there to be a USB charger on the bench. The goal isn’t to replace trees with tanks but to use them where it makes sense to do so.
To echo what some other people have said, these algae tanks absolutely should not be used instead of trees. If I see a tree get chopped down and replaced with one of these, I’ll be sad and angry. However, these can go in places where trees can’t go, like rooftops. And you don’t have to either wait for a tree to grow for a decade or take a tree from somewhere else to install one. It also serves as both a seating area and can mount a solar panel on top. These and trees both have their place and should both continue to be used.
Well Trees don’t make as much money for rich people who own everything and Trees make hot days more comfortable for homeless people
We are in a parasitic relationship with capitalism. Capitalism constantly extracts from life and the environment. When life begin to limit captialism, capitalism will go to great ends to remove life. Capitalism is not sustainable, nor is it naturally occurring. Abolish this evil system.
easier to digest
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.
Also tree roots will tear stuff up
That adds character.
But they provide little shade 😒
Jump in and you won’t need shade to cool down.
Trees don’t generate large profits this quarter, obviously.
They do for a landscaping company…
