Dear Charlie,

If you have your heart set on sucking dirty gas I would recommend building 
some kind of ejector. A fan might get plugged up with tar but with an ejector 
you could use steam, compressed air or water to move the gas. Or the exhaust 
from your car. Simply connect your exhaust pipe to the ejector with a rubber 
garage exhaust hose. Now start your car engine and place a good size brick on 
the gas pedal. Get your reactor cooking and set back while everbody enjoys 
the show.

Tell Jim Mason that Jeff said hi.

Best of luck,


Jeff
