Sawdust burner with hopper

[@TerryDeck]

The yellow drill is augering the sawdust into burn chamber. The chain drive turns the burn chamber so the sawdust keeps burning. Just a very rough prototype. Working on a better one.

Dude this is genius. What is the purpose of the yellow drill at the rear of the hopper? I thought it might be powering an auger pushing the sawdust into the fire, but then I see the chain driven part that I assume to have the same job.
