A New York startup says it can already make gasoline from air on a rooftop, and it demonstrated the process in Manhattan with a machine about the size of a refrigerator

Hmmm. Is this idea BS, or is there something to it?

The idea is that a startup who has created a machine which captures carbon from the air, and then they cause a chemical reaction with water to produce a carbon-hydrogen bond. The result is a liquid, which they are saying is gasoline that can be used in a typical engine. 

Gasoline is, in fact, a carbon-hydrogen bond, which averages around C₈H_18. So it's not complete hokum. 

It just doesn't feel quite right to be able to create gasoline from the air in such a simple way, on a rooftop in Manhattan. 

But who knows? Maybe there's something to this.
