DIY off-grid Slow Cooker




This cook stove is based on a design by Dr. Dieter Seifert. Please follow this link for more information on this. Ben 2 & Ben 3 firewood stoves.


This stove is made up of the parts shown below and can easily be made in a small workshop. The cook stove can be shipped flat packed for assembly locally with just a screw driver.




















Here you can see the cookers being used. They produce less smoke than a conventional 3-stone fire and is more efficient saving on time and money spent on firewood.


















Here are photos of the traditional fireplace used for cooking.
