The Baobab Tree
The baobab tree is a conceptual artificial tree designed to absorb carbon dioxide (CO2) from the air through an automated process. It releases clean, cool air while consuming a minimal amount of energy generated by solar panels at the top of the tree.
This design is minimalistic and can be scaled in size and quantity, with the primary goal of placement in public spaces or city centres where CO2 concentrations are high.
How It Works:
Fans in the tree force air through panels coated with Amine. As the air passes, the Amine absorbs CO2, cooling the air as it travels through the "trunk" and exits at the tree's base.
Sensors are positioned at both the entrance and exit of the panel container to monitor the amount of CO2 entering and leaving with the air. When the difference in CO2 levels becomes low, the doors to the container close, and a water spray is activated. When the water comes into contact with the Amine panels, the CO2 is released and collected in a container with algae. Alternatively, it can be compressed and used in other industries, such as agriculture, or pumped back into the ground.
