Very promising but I'm going to hold out until I actually see this being applied in places like South Korea, literally suffocating from a combination of both local and foreign smog from Korea's favorite neighbor.

You can't really fault me because we've often seen groundbreaking, extraordinary claims, and very little of it is actually realized. Sort of like how we get news about how somebody found a cure for AIDs or Cancer. Again, not trying to shit on anybody, just practicing good old skepticism, I will believe it when my nephews and nieces in Korea are able to breathe in cleaner air and can play outside without wearing industrial face masks. Until then, fingers crossed and hope this is the real deal.

I totally agree on skepticism. We are working hard to prove our economics. We are targeting selling renewable gasoline from the air for a profit next year. It will be much better for air quality too!

How will this improve the global average of air quality? If you are removing the CO2 from the air then reintroducing it back into the same environment (assuming it is not repurposed in another sector e.g. jet fuel, commercial containers) wont the net effect be the same?

I understand this will concentrate the pollution significantly and may even reduce it in the short term, but wont the average effects be the same?

By "air quality" I believe he is saying that an extra benefit to being carbon neutral is that their fuel combusts more purely than fuel made from crude oil. This means less SOx, NOx, particulates, etc.

It'll improve net air quality (if it works) because our current methods of producing fuels themselves require other 'carbon negative' energy.

Hope the best for you guys, I really do! If realized, this could be too seductive for foreign governments that depend on importation of oil and polluting their air to support export industries. Cleaning up the air AND mining the skies for gasoline? Good deal imho.
