Scientists at Columbia University are working on a sort of synthetic tree that aims to capture about 1,000 times as much carbon dioxide as more organic versions. They’re hoping to extend the technology even to heavy-emitting cars and planes.
The units, demo versions of which already exist (this is assuredly not a concept), take CO2 in from the air and turn it into liquid, which is easier to store and manage. Professor Klaus Lackner, lead developer, notes that the synthetic trees are not designed to replace, say, coal plants that reduce emissions from the inside, but this could be one very useful plastic plant if it sees mass production.
