1
Fan draws air into a collector
box and through a filter
CO2 in air
Fan
CO2-free
air
Highly selective filter becomes saturated with CO2
2
When the filter is full the box is closed
and the filter heated to 100C
Heating causes the filter to give up its store of CO2
3
Captured CO2 is mixed
with water and pumped
deep under ground
Water
Basalt rock
Mixture turns to stone in about two years
