    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.

    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.

    It’s been proven that humans didn’t actually get most of their fresh air from the rainforest, but actually from millions of these algea in the sea… Which is actually more logical, since trees do the opposite at night, kinda undoing any advantage they made during the day… Hence why it’s said you should never put a decorative small tree or even plants in the bedroom as they can take away oxygen levels in closed rooms at night. It’s even said not to sleep under trees outside at night cause it can cause respiratory problems.

      They don’t use enough oxygen over night to negate the effect as they use the carbon to grow. It’s still bad to have a lot of plants in your bedroom, but it doesn’t really matter as long as they are relatively small.

          They consume oxygen during the night so when you have a lot of them it can cause respiratory problems, that is for the bedroom

            An effective HVAC system makes this a non-issue. It isn’t like the air is stagnant, the air handler keeps air moving.
