A novel design "convection pressure" alcohol stove featuring both inner and outer flame jets. Click on the time here 7:28 to skip discussion on the limitations of other stove designs. This easily-made stove starts heating the kettle from the moment it's lit (no pre-heating, no "cold pot kill"), has no central cold spot, does not need a pot stand and allows easy retrieval of unburnt fuel for later use. As a bonus, it also works well as a charcoal stove, for a long, slow simmer
The rising column of hot alcohol vapour formed by the lower internal flame jets gently pressurizes the upper half of the stove, forcing the vapour out of the upper jet holes. After secondary ignition, these jets form the main heating source. Make one and it will change the way you look at the humble tin can forever!
