ZEN STOVES - TWISTER AND MAGH STOVES

........The MAGH Twister Stove/ in fact is a double walled vortex stove which uses centrifugal decomposition to mix smoke with air for a more complete burn.

.........Alternately, placing the fan on the side of the stove enables you to build a less complex stove without a bottom which should be easier to build, harder to break, and lighter.
