"One of the biggest changes that makes the SilverFire a real next generation rocket stove is that the airflow pattern has been optimized to get the most usable heat from the least amount of fuel. The bottom of the stove is vented to allow air into the stove body from the base. This feeds oxygen in from the bottom of the fuel chamber and also in through a secondary set of ventilation holes above the burning wood. Once this rocket stove starts burning, it produces no smoke, as long as you tend the fire a bit."
