The WGS is a turbo wood gas stove, i built from galvanised iron sheet, it burns clean purplish flames
it takes a maximum of 1 Kg which burns in gas (flame) mode for approximately 45 minutes and in charcoal mode for 10 minutes at its lowest setting, which is basically appropriate for normal cooking.
It boils 1 litre in 5 minutes at highest setting! 200 g of wood chips will cook Nsima(corn meal)! i will burn a piece of cardboard the size of an A4 with no smoke in 3 minutes! it runs a small PC fan on a cellphone battery! for 4 days!
