Treepex is not a concept, but rather a real device that claims to use living tree cells compressed in replaceable cartridges to transform carbon dioxide into oxygen, emulating a tree’s ability to filter polluted air into mineral-enriched air. It was developed by a Georgian, Tbilisi-based, startup using a new technology called CRISPR, which is allegedly able “to extract the DNA of actual trees to recreate the living cells that are responsible for photosynthesis” by simply inserting a cartridge into the tubular Treepex.
