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.

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.

The most dystopian thing I've seen... Fuck, idk, it's all pretty dystopian these days, I've lost count

How's my dog supposed to piss on that

I don’t think anything’s wrong with trees, but maybe we could also have some of these as well as trees ?

Replace the advertisements on bus stops with a really cool green liquid wall 😮 (but they’d have to make the glass super thick, these things tend to be vandalized from time to time)

Very cyberpunk

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.

1. Wrong community, maybe? Lol

2. 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.

Have you ever seen how long it takes for a tree to grow?

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.

Trees grow and rip up the pavement around them. I do love the canopy though

Why is this in self hosted?

Nothing is wrong with trees, but the microalgae CO2 capture rate is 50x higher````` .

I like how everyone is acting like it is normal to have this in self hosted

at least give it some shape that is not an eye sore to start with

Is it FOSS?

Because there's no serious answers being given even though there are at least 2:

• trees have roots, roots ruin any nearby human infrastructure. You'll note this says "in urban environments" and that there are trees nearby, so this is probably the big reason
• trees need maintenance, which costs money. this is a stupid reason imo, but it's one nonetheless
• algae is cool, ok?

Liquid Trees! Slam it down fast!
