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.

This was my thought as well. They should be used in addition to, not as a replacement for, trees, bushes, and grass.

It does make me wonder, though, whether or not we could use these to help capture more carbon than we're creating.

That would require a gigantic scale of operations, and trees are just waaaay more economical.

Think of entire oceans full of algae not being enough to stop what's currently going on with ecological situation.
