It's ok, I got it now. I would probably use red brick and some wet sand to make a makeshift encasement for the chimney just because. I'd think using a 120-180 mm computer fan rigged to a battery pack to drive the fan and pickup all the smoke would be mighty useful. Probably with a large hole mesh filter to filter out any bugs. Probably use an aluminum sheet wrap to stiffen the end and then drill and loop some metal wiring to keep the fan in place.So sorry. I did a poor job explaining myself.
The chimney starter with lump would be on the ground outside the Egg. The drier vent would move the smoke from the chimney starter to the exterior opening of the Egg’s lower vent door. So the Egg was only receiving the smoke...the heat reduced on the trip to the Egg. Let me see if I can find a picture.
