Big Green Egg?

yup.. Uncle Ray is the man to answer this.

But from my limited experience it runs very efficient once the ceramic is heated up with a small amount of lump with small chunks of wood. Uses a small pan of water as a damper/drip catch if you want. Takes a while to respond to damper controls and a long time to loose heat if u need to. Capacity is limited. Its a dream cooker for low volume low/maintance cooking. If your looking into it, look at the kamodo cooker also. There are comparison charts on there web site too.
