7 ounces of this yellow powder can capture as much CO2 as a tree

A new material developed at UC Berkeley could help bring down the cost of capturing carbon dioxide from the air.
Earlier this year, scientists at the University of California, Berkeley, filled a device with bright-yellow powder, connected it to a tube, and stuck the tube through the wall of a lab. Over the next 20 days, they used the material to pull CO2 from the outdoor air. Then they extracted the CO2 from the powder, repeating the process 100 times.
