What is the best way to remove/ block smog from a Med - Large city? Can it be achieved within 8 years?

Question

What I looking for is a reliable and cost effective way to reduce the number of "Unhealthy Air Days" in urban areas. Until the majority of transportation and energy machines operate at low to zero emissions many cities across the world will experience weeks of the year when it will be unhealthy to breath. The "Spare the Air" campaign doesn’t seem to be reducing the number of unhealthy days in a year. Is there anyone who can think of a to move smog out of or to block if from moving into heavily populated areas?

Answer 1

The internal combustion burnes very inefficient.The only way to reduce air pollution is to change the fuel.Burning ethanol or methanol with gasoline would completely solve the problem.

Answer 2

Reducing the number of Unhealthy Air Days is easy. Just change the standard to a higher level.

If you are talking about smog, you need to lower/stablize the number of people/cars that are in the urban area. Reliable and cost effective is dependant on the area you live it. Reducing/stabalizing the number of people in LA is possible because of the suburban sprawl that is happening in places like Riversdie County. This of course doesn't really reduce smog, but moves it out to the suburbs.

The "Spare the Air" campaign is not meant to reduce the number of unhealthy days but to prevent it from getting to "Very Unhealthful".

You cannot block smog, but you can delay the formation of photochemical smog by changing the amount of nitrous oxide compounds in the air.

Answer 3

Build a large thermally operated tower and pump the smog into the sky. ie suns warms air which rises...once it starts it continues.
