Aircela demonstrated the process, making gasoline directly from air, in front of a live audience in New York. We built a working machine,” Dahlgren said in a statement. Direct air capture, the approach used by Aircela, pulls CO₂ directly from the atmosphere. These separate sections handle the stages of air capture and fuel synthesis. On the back of the machine is a standard-looking gasoline nozzle, similar to what you’d find at a gas station.
