I think that the $45 filter is a cool temporary help but in the long run we should be moving to electric cars.
That being said, Im curious as to the source of energy that is used to charge that electric car. If it is coal or nuclear power than I really think we should be working towards something else. That isn't to say that we need to immediately kill all those jobs that coal and nuclear power create but transition to something else. The sooner the better.
I am very skeptical about the real effect of the filter on cars emissions, I mean, this carbon dioxyde can be filtered and kept somewhere but it cannot be destroyed so simply just with a $45 filter or we would have no more global warming problem if it was that simple, it seems like a scam to me but maybe it help a little bit. Anyone knows how it could really work ?
