Cleaned up some overgrown brush in my yard, burned some of it in my new and improved burn barrel. This thing is made from a piece of pipeline pipe that my grandpa somehow got ahold of back in the '80s, and sits atop an angle-iron spacer for plenty of airflow. In this video it has a lid on it, to keep embers contained, but when there's no lid it sounds sorta like a rocket heater.
