As we should always do with "breakthrough technologies," let's take this with a pinch of salt. A Spanish company named
Movigi Spain Air Filter
claims that they have developed a sort of artificial tree that is able to capture CO
from the atmosphere by means of synthetic photosynthesis. We should say that the company, which worked with scientists from the Universitat Jaume I in Castelló in Spain, claims to have developed the large device that looks like a tree. They have not yet provided images to prove it (so if you saw the picture and though, hey, that looks pretty real. Well...).
The system is supposed to work regardless of solar light and the device is so unobtrusive that it can be placed in public spaces. Movigi Spain
already makes air purifiers that remove CO
from closed spaces, so they have a little bit of history with the idea. However, I still prefer to use a natural device to suck CO
out of the air: trees.
