During emergency and for use in open areas a inverted tornado of fire can be easily created from a used tin can, as shown in the above photos. Dry chips of wood / wood shavings / leaves / etc., biomass can be used as fuel. If all the biomass is soaked in kerosene it lasts longer. For ignition any combustible material should be used. A small ring of 2 inches diameter can easily pass through the tornado. If glass cover is used the light will be more brighter. Don't try it in closed environments it is dangerous. The end product is charcoal, which can be used for soil amendment. (Terra Preta nova).
