The 2017 appropriate technology course developed an outdoor rocket oven. The oven's roof may be adapted so that the oven can be used indoors. During construction, welding and raw steel oven racks that can endure 1000 degrees Fahrenheit were used. The video also covers seasoning racks and storing the oven in bad weather. We also learn about j-tube and wood feed design and how to permanently install the oven. For pizza and other high-temperature cooking, this video shows how to build and use a rocket oven outside.
