"The major culprits from transportation sources are carbon monoxide (CO),[9][10] nitrogen oxides (NO and NOx)"

Transforming and removing CO2, while a greenhouse gas, isn't going to address the environmental issue.

Very cool that they can now do this though, and I hope that it takes off so we dont have to keep using corn; because corn sweats and mass amounts of it can attribute to higher humidity which makes the world feel hotter! Would be nice to go to the track over the summers if it'd be bearable!

It may not help with smog, but will definitely help with global warming as CO2 is one of the major parts of exhaust fumes.

Maybe we will see ethanol and water cars coming in the future with drastically increased mpg, although it seems like electric is the way to go.

As well as the major emissions of any living animal. You may have picked up on a few of us posting in this thread not being convinced of AGW being a serious problem...
