Flexburn - 3 Stage Burn

[Daryl]

I wanted to share this because of the concept of a 3 stage burn.  The smoke from the fire is pulled down into a secondary combustion chamber and then moves to a catalyst.  While trying to get information about the Flexburn technology I came across mixed reviews.  Everything from VC is a piece of crap to cutting edge technology.  I am fascinated by science so I am intrigued by the stove and possibilities for the future.  I am not sure the stove is any good but it sure is interesting.

Low mass stoves extend burn times (thus extending the heating cycle) by reducing air, making the catalyst necessary.
High mass stoves extend the heating cycle by storing heat in mass; the fire can be intense, burning cleanly without expensive catalysts.
