The stove was created by Dutch designers Roel de Boer and Michiel Martens.
Users start by placing a log (a section of tree trunk, really) on the adjustable-height support stand, then pushing it into the cylindrical stove – presumably a small fire has already been started in there, using kindling. Once the business end of the log is in, a steel diaphragm is closed around it. From there, users just periodically push the log in a little farther, as the end of it burns away.
