Sorry for a probably obvious question - I see that the charcoal is gravity fed using the chamber in the back of the unit - gravity loads charcoal into the fire box - how does the fire not climb up the charcoal chamber? How is the fire kept contained in the fire box?
Maybe there is some type of baffle or something that keeps the fire in the fire box?
Looks pretty cool though - I'm sure it will cook for a long time and if you need more fuel - I guess the idea is to just drop some more down the gravity chamber and reload.
