I just saw on the news a small piece about a volcano dome collapsing, (didn't catch where it was) which of course sent tons of ash spilling onto the local town. As I saw a guy wiping what looked to be about 4-5 inches (10-13cm) of ash off his car, it reminded me of the dust that enveloped NYC after the WTC towers came down. I also wondered what could be done to make a car run in such conditions if he had to get out of town in a hurry. I doubt he would have made it very far before the air intake was completely clogged.

Now, we doni't have many volcanoes here in VA, or tall buildings for that matter, and driving out would probably be a poor choice in either event, but is there a way to keep the air intake from clogging under these conditions to at least make it an option?

Any ideas?

Chris.
