Selfhosted

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.

Why is this on the self hosting community

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

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

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 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.

It's not an either/or thing, the tank in the picture is literally sitting under a tree

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.

Why is this in self hosted?

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.

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

Not liquid enough.

How's my dog supposed to piss on that

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?
