How Power Grids Work

UP NEXT: Carbon Capture-to-fuel Is Almost Here

This rendering shows Carbon Engineering's proposed air contactor design. This unit would be one of several that would collectively capture 1 million tons (907,184 metric tons) of CO2 per year.

It be nice if we could pull CO2 out of thin air and transform it into a fuel. HowStuffWorks looks at the science and how far off in the future it is.
