Arizona State University is taking a new step to combat climate change by installing its first “mechanical tree” in Tempe that removes carbon dioxide from the air, just as real trees do.
The trees, which are actually shaped like large tubes, remove carbon dioxide by catching carbon molecules on a uniquely absorbent sorbent material. The tree technology is also passive, meaning it does not need energy-consuming fans to direct air into its capture process.
These devices, called MechanicalTrees,…
