Bill Knauss' Home and Greenhouse Gasifier
Bill has been working developing TLUD greenhouse and home heaters for a project in Mexico where the plan to use pecan shells for heating applications, and use the biochar to help restore soil fertility. He's done a nice job designing the fan system to detect the heat inside the burner and buzz to remind the user to pay attention to the stove when the fuel canister needs attention.
Bill has also developed a comal style stove top for the TLUD stove that can use pecan shells, wood chips, or other crop residues for cooking.
The TLUD designs that are the basis for the combustion component of this stove are found here: http://www.drtlud.com
