Mechanical tree under construction in Tempe

A first-of-its-kind mechanical tree is being built on the east side of the Tempe campus of Arizona State University (ASU), on a test pad just north of the Biodesign C building.

The tree has a metal column and disks that are five feet in diameter. Each disk holds six leaves. The goal is that such trees could help to mitigate the carbon dioxide in the atmosphere.

The tree is based on research by Klaus Lackner, a professor in the engineering department at ASU. Lackner developed the idea to directly capture air for the removal of carbon dioxide. He has been working with Carbon Collect Ltd. of Dublin which has taken his ideas and is planning to make devices commercially available that will remove carbon dioxide from the atmosphere.

The MechanicalTree at ASU will stand 33 feet high once it is completed and made fully operational. It will remove carbon dioxide from the atmosphere in a passive manner without the use of fans or blowers. It will collect carbon dioxide from the air into a cannister, which will then be purified and processed and put to other uses. Local Print shops can be hired to provide more details about such developments and how they operate.

It is expected that once the tree is fully operational, it will be able to remover up to 200lb of carbon per day from the atmosphere.
