Rocket stove/brick chimney for open air grilling.
Build your pit by placing 5 bricks to be the base, and then leave a void in the middle to act as the burn chamber. The draft effect is what makes it efficient.
I controlled the heat with this log, and also fed the fire with the small amount of wood shavings for flavor. All through the brick sized opening.
It took about 12 minutes to get my steaks to medium.

Nice design from google
This is a good design as well, but I like being able to perfect my version before I do anything permanent.
I may copy this design.
Excellent design. Seek additional ideas on YouTube. Thanks and happy Easter.
